- What is periodization?
- The planned long-term variation of training volume and intensity over time to peak performance and manage fatigue.
- What % of CSCS Scientific Foundations is Exercise Science?
- About 60% of the Scientific Foundations section — roughly 48 of the 190 scored questions — making it the single highest-yield CSCS domain.
- Hierarchy of skeletal muscle organization (largest to smallest)
- Muscle → fascicle → muscle fiber (cell) → myofibril → sarcomere. The sarcomere is the functional contractile unit.
- What is the sarcomere?
- The functional contractile unit of muscle, bounded by Z-lines and built from overlapping thick (myosin) and thin (actin) filaments.
- State the sliding filament theory
- Myosin cross-bridges bind actin and pull the thin filaments toward the sarcomere center, shortening the sarcomere while the filaments themselves do not change length.
- During contraction, which sarcomere regions narrow vs. stay constant?
- The H-zone and I-band narrow as filaments slide inward, but the A-band stays a constant length.
- Myosin vs. actin: which is thick, which is thin?
- Myosin is the thick filament whose cross-bridges pull; actin is the thin filament that myosin attaches to and pulls during the power stroke.
- Role of ATP in the cross-bridge cycle
- ATP binds myosin to detach it from actin, and its breakdown re-cocks the head. Without ATP cross-bridges cannot detach — this causes rigor.
- What triggers calcium release in a contraction?
- An action potential travels down the T-tubules, signaling the sarcoplasmic reticulum to release calcium into the sarcoplasm.
- What does calcium bind to start contraction?
- Calcium binds troponin, which shifts tropomyosin off actin's myosin-binding sites, allowing cross-bridges to form.
- Neurotransmitter released at the neuromuscular junction
- Acetylcholine, released when the motor neuron action potential reaches the NMJ; it depolarizes the sarcolemma to begin excitation.
- Function of T-tubules
- Invaginations of the sarcolemma that carry the action potential into the muscle fiber's interior to trigger SR calcium release.
- Function of the sarcoplasmic reticulum
- The intracellular membrane network that stores and releases calcium to control muscle contraction, then pumps it back to allow relaxation.
- Role of tropomyosin at rest
- At rest, tropomyosin covers actin's myosin-binding sites, preventing cross-bridge formation until calcium binds troponin.
- Order the EC-coupling sequence after ACh release
- Sarcolemma depolarizes → impulse down T-tubules → SR releases CaX2+ → CaX2+ binds troponin, tropomyosin shifts → cross-bridges power stroke → CaX2+ pumped back, muscle relaxes.
- Type I muscle fiber characteristics
- Slow-twitch: fatigue-resistant, mitochondria- and capillary-rich, high oxidative enzymes and myoglobin; suited to endurance and recruited first.
- Type II muscle fiber characteristics
- Fast-twitch: larger, generate more force and power, more glycolytic with greater PCr stores, fatigue faster; recruited as force demand rises.
- Type IIx vs. Type IIa fibers
- Type IIx are the most powerful and glycolytic and fatigue fastest; Type IIa are intermediate in speed, force, and fatigue resistance.
- Which direction does training shift fiber types?
- Training shifts fibers along the continuum from IIx toward IIa — NOT from Type II to Type I.
- What is a motor unit?
- A single motor neuron plus all the muscle fibers it innervates; all fibers within one motor unit are the same fiber type.
- State the size principle
- Motor units are recruited in order of size: smaller (Type I) units first, larger (Type II) units last as force demand increases.
- Why does heavy explosive work develop Type II fibers?
- High force/power demands recruit larger motor units last (size principle), so only heavy or explosive efforts preferentially recruit Type II fibers.
- Which fibers store more phosphocreatine and glycolytic enzymes?
- Type II fibers store more PCr and glycolytic enzymes; Type I fibers hold more capillaries, myoglobin, and mitochondria.
- Name the three energy systems
- The phosphagen system, glycolysis (fast/slow), and the oxidative system. They overlap rather than switching fully on and off.
- Phosphagen system: duration, fuel, use
- Uses stored ATP and phosphocreatine for immediate, maximal-power efforts under ~10 seconds, such as a 1RM or sprint start; fastest ATP rate.
- Fast glycolysis: duration and product
- Anaerobic breakdown of glucose/glycogen to lactate, dominating efforts of roughly 10 seconds to 2 minutes; nets about 2 ATP per glucose.
- Fast vs. slow glycolysis
- Fast glycolysis converts pyruvate to lactate without oxygen; slow glycolysis sends pyruvate into the mitochondria when oxygen is available.
- Oxidative system: when does it dominate?
- It is the primary supplier at rest and during prolonged, lower-intensity work beyond about 3 minutes; slowest ATP rate but most ATP yield.
- Net ATP: anaerobic glycolysis vs. full oxidation
- Anaerobic glycolysis nets ~2 ATP per glucose, while complete oxidation of one glucose yields roughly 38 ATP.
- Why can't fat fuel high-intensity work?
- Fat provides far more ATP per molecule than glucose but cannot be mobilized fast enough to meet the rapid ATP demand of high-intensity efforts.
- Which energy system needs the longest rest, and why?
- The phosphagen system, because phosphocreatine resynthesis is slow (via the oxidative system) relative to the brief, maximal work bout.
- Work-to-rest ratio to train the phosphagen system
- About 1:12 to 1:20, giving near-complete PCr recovery to preserve maximal power on each repetition.
- Work-to-rest ratio for fast glycolysis
- Roughly 1:3 to 1:5, targeting glycolytic conditioning with incomplete recovery between bouts.
- Work-to-rest ratio for the oxidative system
- Approximately 1:1 to 1:3; shorter rest biases the session toward oxidative (and glycolytic) adaptations.
- 5-second phosphagen sprint: how much rest?
- Using the 1:12 to 1:20 ratio, about 60 to 100 seconds of rest (5×12 to 5×20) to allow PCr resynthesis and preserve power.
- What is EPOC?
- Excess post-exercise oxygen consumption — elevated oxygen uptake after exercise that restores ATP and PCr, clears lactate, and returns the body to rest.
- How does intensity affect EPOC?
- Higher-intensity exercise produces greater EPOC, because more ATP/PCr restoration, lactate clearance, and oxygen-store recovery are required.
- First-class lever arrangement (and example)
- Fulcrum sits between force and resistance (Force–Fulcrum–Resistance); favors balance. Example: head/neck on the atlanto-occipital joint.
- Second-class lever arrangement (and example)
- Resistance sits between fulcrum and force (Fulcrum–Resistance–Force); favors force / mechanical advantage. Example: a calf raise (plantarflexion).
- Third-class lever arrangement (and example)
- Force is between fulcrum and resistance (Fulcrum–Force–Resistance); favors speed/ROM. Example: a biceps curl at the elbow — the most common in the body.
- Define torque
- Rotational force, equal to force multiplied by the perpendicular moment arm (the distance from the joint axis to the line of force).
- What is the moment arm?
- The perpendicular distance from a joint's axis of rotation to the line of force; a longer resistance moment arm makes an exercise harder.
- Why does an exercise feel hardest at one point in the ROM?
- Because that is the point of greatest mechanical disadvantage — the longest resistance moment arm — producing the highest required torque.
- Why must muscles generate large internal forces?
- Most human levers are third-class, favoring speed and ROM over force, so muscles produce large internal forces to move comparatively light external loads.
- What two factors determine stability?
- Center of gravity and base of support: a lower center of gravity over a wider base of support is more stable.
- Define the stretch-shortening cycle (SSC)
- A rapid eccentric (lengthening) action immediately followed by a concentric (shortening) action that produces more force than the concentric action alone.
- Eccentric vs. concentric muscle action
- Eccentric: muscle lengthens under tension (e.g., lowering a load), storing elastic energy. Concentric: muscle shortens under tension to produce movement.
- Three phases of the SSC
- Eccentric (stores elastic energy, triggers the stretch reflex), amortization (the brief eccentric-to-concentric transition), and concentric (releases stored energy).
- What is the amortization phase?
- The brief eccentric-to-concentric transition in the SSC; a shorter amortization phase yields more power because less elastic energy is lost as heat.
- Why do fast ground contacts beat slow ones in plyometrics?
- A shorter amortization phase preserves stored elastic energy; if the transition is delayed, that energy dissipates as heat and power is lost.
- Two sources of the SSC's extra force
- Stored elastic energy from the eccentric stretch plus the muscle-spindle stretch reflex contraction, released during the concentric phase.
- Function of the muscle spindle
- A proprioceptor that senses rapid muscle stretch and triggers a protective reflexive contraction — the stretch reflex that aids the SSC.
- Function of the Golgi tendon organ
- A proprioceptor at the muscle-tendon junction that senses high tension and can inhibit contraction to protect the muscle-tendon unit.
- Muscle spindle vs. GTO: stimulus and response
- The muscle spindle senses rapid stretch and drives contraction; the GTO senses high tension and inhibits contraction to protect against injury.
- Primary anabolic hormone and its action
- Testosterone — promotes protein synthesis and interacts with the nervous system; rises acutely with large-muscle, heavy, high-volume, short-rest training.
- What resistance protocol maximizes testosterone release?
- Large-muscle-mass, heavy-load, high-volume resistance exercise with short rest periods produces the greatest acute testosterone surge.
- Growth hormone: action and what maximizes it
- GH promotes tissue growth and stimulates IGF-1 release; its spikes are greatest with high-volume, short-rest, lactate-producing protocols.
- What is IGF-1?
- Insulin-like growth factor-1, an anabolic hormone released downstream of growth hormone (and tissue damage) that mediates many of GH's tissue-building effects.
- Cortisol: action and what elevates it
- A catabolic adrenal hormone that mobilizes fuel and breaks down protein; it rises with prolonged, high-stress training and overtraining.
- Acute vs. chronic hormonal response
- An acute hormone surge follows a single session; chronic adaptation reflects long-term changes in receptor sensitivity and resting hormone concentrations.
- What are the catecholamines and what do they do?
- Epinephrine and norepinephrine — fight-or-flight hormones that rapidly increase force production, energy availability, contraction rate, and arousal.
- What is arousal in sport psychology?
- General physiological and psychological activation of the athlete along a continuum from deep sleep to extreme excitement. It is a neutral state, not inherently positive or negative.
- Arousal vs. anxiety
- Arousal is neutral activation; anxiety is the negative emotional interpretation of that arousal. The exam tests this distinction directly.
- What are the two components of anxiety?
- A cognitive component (worry, negative thoughts) and a somatic component (bodily symptoms like elevated heart rate and muscle tension).
- State the inverted-U theory
- Performance improves as arousal rises to an optimal moderate midpoint, then declines as arousal climbs too high. It is the keyed answer for the general arousal-performance question.
- Inverted-U: how does optimal arousal vary by task?
- Fine-motor or complex skills peak at LOWER arousal; gross-motor strength and power tasks tolerate and peak at HIGHER arousal.
- What does drive theory predict?
- A linear rise in performance with arousal (more arousal = better performance). It holds mainly for simple, well-learned tasks and is the classic inverted-U distractor.
- What is IZOF?
- Individual Zones of Optimal Functioning: each athlete has a personal optimal arousal BAND rather than one universal midpoint. Cue: optimal level differs by athlete.
- What does the catastrophe model claim?
- High cognitive anxiety causes a sudden, dramatic performance collapse rather than a gradual decline. Cue: rapid drop-off, not a smooth curve.
- Which arousal theory is the keyed general answer?
- The inverted-U theory. Drive theory and IZOF are the contrasting distractors.
- Best arousal level for a heavy 1RM back squat?
- Higher arousal. Gross-motor strength and power tasks tolerate higher arousal levels than fine-motor skills.
- Hallmarks of effective goal setting
- Goals should be specific, measurable, and moderately difficult but realistic. Emphasize controllable process/performance goals over pure outcome goals.
- Process goals vs. outcome goals
- Process goals focus on controllable actions and technique; outcome goals (e.g., winning) depend on opponents. Process goals are stronger, more durable motivators.
- Why are outcome goals weaker motivators?
- Outcomes like winning depend on opponents and factors outside the athlete's control, making them less reliable drivers than controllable process goals.
- What is self-efficacy?
- An athlete's situation-specific belief that they can successfully execute a particular task. It is task-specific, not a global trait.
- Name Bandura's four sources of self-efficacy, ranked
- Strongest to weakest: (1) mastery experiences, (2) vicarious experience, (3) verbal persuasion, (4) physiological/emotional states.
- Strongest source of self-efficacy?
- Mastery experiences (past performance accomplishments). Engineering a recent, achievable success is the most powerful confidence builder.
- What is a vicarious experience (self-efficacy)?
- Building efficacy by watching similar others succeed (modeling). It is the second-strongest source of self-efficacy in Bandura's model.
- Where does verbal persuasion rank in self-efficacy?
- Third — weaker than mastery and vicarious experience but stronger than physiological/emotional states. It is credible encouragement or feedback.
- Weakest source of self-efficacy?
- Physiological and emotional states — the athlete's interpretation of arousal, fatigue, and mood. It is Bandura's weakest of the four sources.
- Best first move to build an anxious athlete's confidence?
- Engineer an early, achievable success (e.g., a confidently completed submaximal set), because mastery experiences are the strongest efficacy source — before any pep talk.
- Intrinsic vs. extrinsic motivation
- Intrinsic = doing an activity for its own enjoyment, satisfaction, or mastery. Extrinsic = doing it for external rewards or to avoid punishment.
- Which motivation type drives long-term adherence?
- Intrinsic motivation. The exam favors it as the more durable driver of long-term training adherence.
- What is imagery (mental rehearsal)?
- Creating a vivid, controllable, multisensory mental representation of a skill or competition. It aids both skill learning and arousal regulation.
- What makes imagery most effective?
- It should be vivid, controllable, and rehearsed from the athlete's own (internal) perspective, using multiple senses.
- What is self-talk?
- Use of cue words, instructional phrases, or reframing statements to direct attention and regulate emotion during performance.
- Technique to reduce somatic anxiety?
- Progressive muscle relaxation (tensing and releasing muscle groups) and controlled breathing reduce bodily/somatic anxiety and arousal.
- What are psyching-up techniques used for?
- Strategies to deliberately RAISE arousal before high-force or power tasks (e.g., a max lift), when more activation aids performance.
- Whose model gives the stages of motor learning?
- Fitts and Posner's three-stage model: cognitive, associative, and autonomous stages of skill acquisition.
- Describe the cognitive stage of motor learning
- Beginner phase: many large errors, heavy conscious thought, and a need for frequent, simple instruction and demonstration.
- Describe the associative stage of motor learning
- Intermediate phase: fewer, more consistent errors as the athlete refines the movement pattern. Feedback begins to fade.
- Describe the autonomous stage of motor learning
- Advanced phase: movement is near-automatic, freeing attention for strategy and tactics. Feedback only as needed.
- Athlete makes many large errors and needs constant cues — which stage?
- The cognitive (beginner) stage of motor learning. Provide frequent, simple instruction and demonstration.
- How should feedback frequency change across motor-learning stages?
- Provide frequent feedback early (cognitive stage), then progressively fade it so the athlete learns to self-detect errors.
- Knowledge of results vs. knowledge of performance
- Knowledge of results = feedback about the movement's OUTCOME (success/failure). Knowledge of performance = feedback about movement QUALITY/technique.
- Energy yield of carbohydrate
- 4 kcal per gram.
- Energy yield of protein
- 4 kcal per gram, the same as carbohydrate.
- Energy yield of fat
- 9 kcal per gram — the highest of the macronutrients. A common distractor swaps this with 4.
- Energy yield of alcohol
- 7 kcal per gram. It is not a recommended fuel and impairs recovery.
- Recommended carbohydrate intake for athletes
- Roughly 5 to 10 g/kg/day depending on training load, with higher loads requiring more.
- Recommended protein intake for athletes
- 1.2 to 2.0 g/kg/day to support adaptation and repair. A distractor uses the sedentary RDA of 0.8 g/kg.
- Per-meal protein dose to maximize MPS
- About 20 to 40 g of protein per meal to maximize muscle protein synthesis.
- How many essential amino acids are there?
- 9 of the 20 amino acids are essential — the body cannot synthesize them, so they must come from the diet.
- What is the glycemic index?
- A ranking of how quickly a carbohydrate raises blood glucose. High-GI foods speed glycogen replenishment; lower-GI foods give steadier energy.
- Best GI choice immediately post-exercise?
- High-glycemic-index carbohydrates, because they speed glycogen replenishment right after training.
- What percent of calories should come from fat?
- Generally 20 to 35% of total calories.
- Calculate energy: 350g carb, 130g protein, 90g fat
- Carb 350x4=1,400; protein 130x4=520; fat 90x9=810. Total = 2,730 kcal.
- Is 1.6 g/kg/day protein appropriate for an athlete?
- Yes. 1.6 g/kg/day falls within the recommended 1.2 to 2.0 g/kg/day athlete range.
- What body-mass loss marks the dehydration threshold?
- About 2% loss of body mass, where performance and thermoregulation begin to decline. A distractor uses 5%.
- Post-exercise rehydration target per kg lost
- Roughly 1.25 to 1.5 L of fluid per kilogram of body mass lost — more than the raw weight lost, to account for ongoing losses.
- Creatine loading protocol
- About 20 g/day for 5 to 7 days, then a 3 to 5 g/day maintenance dose.
- Creatine saturation without a loading phase
- Taking 3 to 5 g/day reaches the same muscle stores in about 3 to 4 weeks without a loading phase.
- What does creatine do physiologically?
- It increases phosphocreatine stores, supporting the ATP-PC energy system for short, high-intensity efforts. It is the most-tested ergogenic aid.
- What is DSHEA and why does it matter?
- The Dietary Supplement Health and Education Act of 1994. Supplements need NOT prove safety or efficacy to the FDA before sale — a recurring gotcha.
- Are dietary supplements FDA-approved before sale?
- No. Under DSHEA, supplements are not required to prove safety or efficacy to the FDA before being marketed.
- What are the three components of the female athlete triad?
- Low energy availability, menstrual dysfunction, and impaired bone health. The three are interrelated.
- Root cause of the female athlete triad?
- Low energy availability — insufficient dietary energy for both training and physiological function — drives the menstrual and bone-health components.
- What is RED-S?
- Relative Energy Deficiency in Sport — the broader syndrome of impaired function caused by low energy availability in athletes of ANY sex.
- What is low energy availability?
- Insufficient dietary energy to support both training and physiological function. It is the root cause of the female athlete triad and RED-S.
- What share of Scientific Foundations is Sport Psychology?
- About 25% of the Scientific Foundations section (~20 scored questions). Nutrition is 15% (~12 questions).
- How are CSCS nutrition distractors typically built?
- By swapping one value for an adjacent one (e.g., fat 4 vs 9 kcal/g, protein 0.8 vs 1.2-2.0 g/kg, 2% vs 5% dehydration). Memorize exact values.
- Five resistance training technique fundamentals?
- A stable grip, correct grip width, balanced body/limb position, a full but controlled range of motion, and proper breathing. These are the baseline a coach establishes before adding load.
- Pronated grip?
- An overhand grip with palms down and knuckles up. It is used for most pulls, rows, and presses.
- Supinated grip?
- An underhand grip with palms up and knuckles down. It is used for biceps curls and chin-ups.
- Neutral grip?
- A grip with palms facing each other and knuckles pointing to the side. It is used for hammer curls and neutral-grip rows.
- Alternated (mixed) grip?
- One hand pronated and one supinated. It resists the bar rolling out of the hands on heavy deadlifts.
- Closed grip vs. open (false) grip?
- A closed grip wraps the thumb around the bar and is the safe default; an open (false) grip leaves the thumb on the same side as the fingers and is less secure.
- Breathing rule for the sticking point?
- Exhale through the sticking point (the hardest part of the lift) and inhale during the eccentric (lowering) phase.
- Valsalva maneuver?
- Forced exhalation against a closed glottis that raises intra-abdominal pressure to brace the trunk during maximal lifts. It spikes blood pressure, so it is reserved for experienced, healthy lifters on the heaviest reps.
- High-bar back squat bar placement?
- Across the posterior deltoids and upper trapezius, just below the C7 vertebra. The bar sits on muscle, not on the bony spine.
- Standard back squat depth cue?
- Descend until the thighs are at least parallel to the floor while the knees track over the feet, keeping a neutral spine and eyes forward.
- What do Olympic lifts primarily train?
- Power via triple extension — the simultaneous, explosive extension of the ankles, knees, and hips. They are the exam's premier power exercises.
- Triple extension?
- The simultaneous, explosive extension of the ankles, knees, and hips that produces power in Olympic lifts and jumps.
- Power clean phase sequence?
- First pull, transition (scoop/double-knee bend), second pull, catch, then recovery. The exam asks you to identify or correct a specific phase.
- In which power clean phase does bar velocity peak?
- The second pull, where the explosive triple extension occurs. This is the most powerful phase of the lift.
- Why must Olympic lifts be coached early in a session?
- They demand speed and skill (technique-sensitive), so they should be performed when the lifter is fresh. Note: placing them first is a Program Design choice, not a Technique cue.
- Power clean fault: early arm pull. Correct it?
- Cue the lifter to keep the arms long and relaxed until triple extension is complete, then pull under. Pulling early with the arms wastes the power of the legs and hips.
- Power clean fault: bar drifting from the body. Fix?
- Cue the lifter to keep the bar close to the body throughout the pull. A bar that drifts forward reduces power and pulls the lifter off balance.
- Correct elbow position at the power clean catch?
- Elbows high and forward in a partial front-squat rack position. A catch with elbows too low is a common fault.
- Transition (scoop) phase of the power clean?
- The knees re-bend back under the bar (the double-knee bend) after the first pull, repositioning the body for the explosive second pull.
- Stretch-shortening cycle (SSC)?
- A rapid eccentric loading stores elastic energy and triggers the stretch reflex, which is then released in a powerful concentric action. It is the mechanism behind plyometric power.
- Three phases of the stretch-shortening cycle?
- The eccentric (loading) phase, the amortization phase (the brief eccentric-to-concentric transition), and the concentric (unloading) phase.
- Amortization phase?
- The brief eccentric-to-concentric transition of the SSC. A shorter amortization phase loses less stored energy and yields more power.
- Why is a short amortization phase desirable?
- Less stored elastic energy dissipates as heat and the stretch reflex contributes more, producing a more powerful concentric action. Minimizing ground-contact time is the key cue.
- Stretch reflex?
- An involuntary muscle contraction triggered by rapid stretch that adds to concentric force during plyometric actions.
- Key plyometric landing cues?
- Land softly on the balls of the feet, keep knees aligned over the toes (no valgus collapse), and minimize ground-contact time on reactive drills like depth jumps.
- Plyometric fault: knee valgus on landing. Fix?
- Cue knees over toes. Knee cave (valgus collapse) is a safety fault, separate from the power-related amortization fault.
- Flat-footed landing with a long pause: what SSC fault?
- A prolonged amortization phase, during which stored elastic energy and the stretch reflex dissipate as heat. Cue minimizing ground-contact time and landing on the balls of the feet.
- Plyometric: is landing correction Technique or Program Design?
- Landing correction is Technique. Foot-contact volume and recovery time are Program Design.
- Plyometric foot-contact volumes by level?
- Roughly 80-100 contacts (beginner), 100-120 (intermediate), and 120-140 (advanced). This is a Program Design number, not a Technique cue.
- Recommended recovery between plyometric sessions?
- 48-72 hours. This is a Program Design prescription rather than a Technique fix.
- Two phases of a sprint?
- The drive (acceleration) phase and the maximum-velocity phase. The body position and ground-contact times differ between them.
- Body position during sprint acceleration?
- Forward body lean with a positive shin angle and longer ground-contact times, applying force backward/horizontally to drive forward.
- Body position at maximum velocity?
- Tall, upright torso with short ground-contact times, applying force straight down (vertically) with a long, consistent stride.
- Triple flexion in sprinting?
- The coordinated flexion of the ankle, knee, and hip of the swing leg to recover the foot. It mirrors the triple extension of the drive leg.
- Overstriding fault in sprinting?
- The foot lands ahead of the center of mass, creating a braking force. Cue the athlete to strike under the center of mass.
- Proper arm action in sprinting?
- A powerful arm drive front-to-back, coordinated with the legs. Strong arm drive supports stride power and balance.
- Agility vs. change-of-direction (COD) speed?
- Agility is reactive change of direction in response to a stimulus; COD speed is pre-planned movement along a known path. True agility involves a perceptual/decision component.
- Cutting and deceleration mechanics?
- Lower the center of mass, widen the base of support, and plant the outside foot to redirect. A low hip position is the cue that enables a sharp cut.
- Pro-agility (5-10-5) test?
- Sprint 5 yards one way, 10 yards to the far line, then 5 yards back to start. It tests lateral change-of-direction speed.
- T-test?
- An agility test that combines a forward sprint to a center cone with lateral shuffles to outer cones, forming a T shape.
- Electronic vs. hand timing accuracy?
- Electronic timing is more accurate but reads slower; hand timing starts late and reads fast (faster, artificially better times).
- Which exercises require spotting?
- Exercises performed over the face/head (bench, incline press), over the trunk (squats), or with the bar on the back (back squat) with heavy free weights.
- How many spotters for very heavy barbell lifts?
- Two or three — one at each end of the bar, plus, for some lifts, one behind the lifter. One spotter suffices for moderately heavy over-the-face or over-the-trunk lifts.
- Where do you spot a dumbbell press?
- At the forearms near the wrists, as close to the dumbbells as possible — never at the elbows.
- Should Olympic lifts be manually spotted?
- No. Do not spot the wrists; teach the lifter to drop or push the bar away (a safe bail). Safety comes from technique and a platform, not from a person.
- How is an overhead press from a rack made safe?
- With power-rack pins set at the appropriate height, not a manual spot. Equipment provides the safety for overhead lifts.
- What must a spotter confirm before the set?
- Communication: the number of reps, whether the spotter assists with a liftoff, and the exact count. Agree on these before the lifter begins.
- Liftoff?
- The spotter's assistance moving the bar from the rack to the start position before the lifter begins the set.
- Requirements for a competent spotter?
- Know the exercise, be strong enough to handle the load, and keep hands ready in an alternated grip just below the bar.
- Technique vs. program design distinction on the exam?
- Technique is how a movement is performed and corrected (cues, faults); program design is how its volume, order, and work-to-rest are prescribed. Read the stem's verb to pick the right framing.
- Most common trap in the Exercise Technique section?
- Answering with the off-domain fact — giving a program-design number (sets, contacts, order) when the stem asks for a technique cue/fault correction, or vice versa.
- Why catch the power clean in a partial squat?
- The partial squat lets the lifter pull under and receive the bar at the shoulders quickly after triple extension, before standing to full extension in recovery.
- Force direction: acceleration vs. max velocity?
- During acceleration force is applied backward/horizontally to propel the body forward; at maximum velocity force is applied straight down (vertically).
- Depth jump primary coaching target?
- Minimizing ground-contact time (short amortization) by landing on the balls of the feet and exploding up the instant the feet land. This preserves the SSC's stored energy.
- What is the four-grip set the exam tests?
- Pronated (overhand), supinated (underhand), neutral (knuckles to the side), and alternated (one over, one under). Know each by feel and typical use.
- Resistance training fundamental: range of motion cue?
- Use a full but controlled range of motion. Partial or uncontrolled movement is a technique fault to correct before adding load.
- Plyometric drill definition?
- An explosive drill using a rapid eccentric-then-concentric muscle action to develop power via the stretch-shortening cycle.
- First pull of the power clean?
- From the floor, the knees extend and the bar rises while the torso angle is held relatively constant. Feet are flat with the bar over mid-foot and shoulders over the bar.
- Recovery phase of the power clean?
- After the catch, the lifter stands to full extension, then returns the bar to the floor under control.
- Which lifts are made safe by environment/skill, not a person?
- Olympic lifts (clean, snatch) and overhead lifts. Safety comes from a safe bail, a platform, and power-rack pins rather than a manual spotter.
- What % of the Practical/Applied section is Program Design?
- Program Design is the heaviest domain, worth about 40% of the Practical/Applied section (roughly 44 of 190 scored questions).
- Strength goal: load, reps, sets, rest?
- At or above 85% of 1RM, 6 or fewer reps, 2 to 6 sets, with 2 to 5 minutes of rest between sets.
- Hypertrophy goal: load, reps, sets, rest?
- 67 to 85% of 1RM, 6 to 12 reps, 3 to 6 sets, with 30 to 90 seconds of rest between sets.
- Muscular endurance goal: load, reps, sets, rest?
- At or below 67% of 1RM, 12 or more reps, 2 to 3 sets, with 30 seconds or less rest between sets.
- Single-effort power: load and reps?
- 80 to 90% of 1RM for 1 to 2 reps, with 2 to 5 minutes of rest. Used for single explosive events like a shot put or one jump.
- Multiple-effort power: load and reps?
- 75 to 85% of 1RM for 3 to 5 reps, with 2 to 5 minutes of rest. Used for repeated explosive efforts.
- Why does power training keep reps low?
- Low reps keep every rep explosive and fast; high reps would induce fatigue that slows movement velocity and defeats the power goal.
- What is 1RM?
- One-repetition maximum: the greatest load that can be lifted once with proper technique. It is the reference point for assigning training loads as a percentage.
- What is the load-repetition continuum?
- The inverse relationship where heavier loads allow fewer reps and lighter loads allow more, mapping load to strength, power, hypertrophy, and endurance goals.
- Why do strength/power goals need longer rest?
- They are more neural and tax the phosphagen (ATP-PC) system; 2 to 5 minutes of rest allows ATP and creatine phosphate to resynthesize so each set stays high-quality.
- How is training volume calculated?
- Volume is sets times reps; volume-load is sets times reps times load. Volume moves inversely with intensity, so heavier loads mean lower volume.
- What is the 2-for-2 rule?
- Increase load when an athlete completes 2 or more reps over the goal on the last set in 2 consecutive workouts.
- Typical load increase when progressing via 2-for-2?
- About 2.5 to 10%, with smaller increments for upper-body lifts and weaker or less-trained lifters.
- Correct exercise order for a session?
- Power/explosive (Olympic) lifts first, then large-muscle multi-joint core lifts, then small-muscle single-joint assistance work.
- Why do Olympic lifts go first in a session?
- They are the most technical and most fatigue-sensitive, so they must be performed while the athlete is fresh to preserve quality and safety.
- Multi-joint vs single-joint: which comes first?
- Multi-joint (core) exercises before single-joint (assistance), and large-muscle before small-muscle, so fatigue does not compromise the priority lifts.
- What are core exercises in program design?
- Structural, multi-joint exercises using large muscle groups (squat, bench press, deadlift) that are prioritized early in a session.
- What are the acute program variables?
- The adjustable elements of a session: exercise choice and order, intensity (load), volume (sets and reps), and rest periods.
- What does plyometric training develop?
- Power, by training the stretch-shortening cycle (SSC) to rapidly transition from eccentric loading to explosive concentric action.
- Name the three phases of the stretch-shortening cycle.
- Eccentric (loading), amortization (the eccentric-to-concentric transition), and concentric (explosive) phases.
- Why does a shorter amortization phase produce more power?
- It minimizes loss of stored elastic energy and keeps the stretch reflex active, so more energy is reused in the explosive concentric phase.
- How is plyometric volume quantified?
- By foot contacts per session (the number of ground contacts), scaled to the athlete's experience level.
- Foot contacts per session for a beginner?
- About 80 to 100 foot contacts per session, at low to moderate intensity.
- Foot contacts per session for intermediate and advanced?
- Intermediate about 100 to 120 (moderate intensity); advanced about 120 to 140 (moderate to high intensity).
- What is a depth jump and how is intensity set?
- A high-intensity plyometric where the athlete steps off a box, lands, and immediately jumps. Intensity is set by box height, typically 16 to 42 inches.
- Strength prerequisite for high-intensity lower-body plyos?
- A common benchmark is a back squat near 1.5 times body weight before performing high-intensity lower-body plyometrics like depth jumps.
- Phosphagen system: duration, intensity, work-to-rest?
- Fuels 0 to ~6 sec near-maximal efforts; conditioning work-to-rest ratio about 1:12 to 1:20.
- Fast glycolysis: duration, intensity, work-to-rest?
- Fuels high-intensity work of ~30 sec to 2 min; work-to-rest ratio about 1:3 to 1:5.
- Oxidative system: duration, intensity, work-to-rest?
- Fuels prolonged low-to-moderate work over ~3 min; work-to-rest ratio about 1:1 to 1:3.
- 6-sec max sprint for phosphagen: how much rest?
- Using a 1:12 to 1:20 ratio, roughly 72 to 120 seconds, allowing near-complete ATP-PC resynthesis so each sprint stays maximal.
- Why does shorter rest train glycolytic tolerance?
- Incomplete recovery forces continued reliance on glycolysis, building tolerance to the resulting metabolic byproducts and fatigue.
- Which training best improves VO2 max?
- Interval training and high-intensity interval training (HIIT) raise VO2 max efficiently.
- What does LSD (long slow distance) develop?
- Continuous lower-intensity aerobic work that builds the aerobic base, improving capillary density, mitochondria, and aerobic endurance.
- Is the work-to-rest ratio Program Design or Exercise Science?
- Program Design. Prescribing the work-to-rest ratio is a dosing decision, even though it attaches to a specific drill; the SSC mechanism itself is Exercise Science.
- What is a macrocycle?
- The largest periodization division, often a full year or competitive season, containing the entire training plan.
- What is a mesocycle?
- A periodization block of several weeks to a few months focused on a specific training quality (e.g., a hypertrophy or strength block).
- What is a microcycle?
- The smallest periodization unit, typically one week of training sessions.
- Linear periodization phase order?
- Hypertrophy/endurance, then basic strength, then strength/power, then peaking or maintenance, often into active rest.
- How do volume and intensity change in linear periodization?
- Across phases, volume progressively decreases while intensity progressively increases, moving from high-volume hypertrophy to low-volume peaking.
- What is undulating (nonlinear) periodization?
- A model that varies volume and intensity within a single week (e.g., a heavy, a moderate, and a light day) rather than gradually across blocks.
- Goal of the hypertrophy/endurance phase?
- Build a work-capacity base with high volume and low intensity, preparing tissues and metabolism for the heavier phases that follow.
- Goal of the peaking phase?
- Maximize performance for competition using very high intensity and very low volume.
- What is the maintenance phase for?
- To retain training adaptations during off-priority blocks, deliberately preventing detraining.
- What is a taper?
- A planned reduction in training volume (with intensity maintained) before competition to remove accumulated fatigue and peak performance.
- How much is volume cut during a taper, and how long?
- Volume drops substantially, commonly 40 to 60% or more, while intensity stays high, typically over about 1 to 3 weeks.
- Why keep intensity high during a taper?
- Maintaining intensity preserves strength, power, and neuromuscular fitness while the reduced volume sheds fatigue, producing a peak.
- What is detraining?
- The loss of training adaptations that occurs when the training stimulus is withdrawn or becomes insufficient.
- Taper vs detraining: key distinction?
- A taper is a planned reduction to peak performance; detraining is an unwanted reversal of adaptations from too little stimulus, a programming failure to prevent.
- Which qualities decline fastest with detraining?
- Anaerobic and power qualities decline relatively quickly, which is why maintenance work is a deliberate design choice in off-priority periods.
- Hypertrophy zone load for a 300 lb bench 1RM at 10 reps?
- Ten reps maps to roughly 75% of 1RM, so about 225 lb for 3 sets of 10 with 30 to 90 sec rest, within the 67 to 85% hypertrophy band.
- Program Design vs Exercise Technique for a movement stem?
- How to perform or correct a movement is Exercise Technique; how to load, sequence, rest, or dose it is Program Design.
- How does volume relate to intensity in resistance training?
- Inversely: as intensity (load) rises toward 1RM, training volume (total reps/sets) decreases, and vice versa.
- Goal of strength/power phase in linear periodization?
- Lower volume with high intensity plus added explosiveness, converting built strength toward sport-specific power.
- What load and reps define a strength prescription?
- At or above 85% of 1RM for 6 or fewer reps; the heavy load and low reps drive maximal-strength neural adaptations.
- Why anchor a scenario answer on the named goal?
- The goal (strength, power, hypertrophy, endurance) selects load, rep range, and rest together as a matched set; distractors pair one correct variable with a mismatched one.
- What % of the CSCS Practical/Applied section is this domain?
- About 15% — 16 of the 110 scored questions. It covers organizational environment, facility design, professional practice, and litigation issues, plus testing/evaluation logic.
- Four phases of facility design, in order
- Predesign, design, construction, and preoperation. Predesign sets the master plan; preoperation finishes interiors, hires staff, and writes policies before opening.
- What happens in the predesign phase?
- The first phase establishes the master plan, budget, needs analysis, and feasibility (roughly 25% of the timeline) before any architectural design work begins.
- What is done in the preoperation phase?
- The final phase finishes interiors, hires and trains staff, and writes policies and procedures so the facility is ready before opening day.
- Single biggest layout driver in facility design?
- Traffic flow — it most affects safety and function when multiple groups train at once. Stronger, faster movements go away from walkways and walls.
- Where should Olympic lifting platforms be placed?
- Away from walkways and walls. Explosive, high-velocity movements need clearance; lighter dumbbell and bodyweight work can sit nearer the perimeter.
- Recommended ceiling clearance for a strength facility?
- 12–14 ft above the tallest equipment or overhead lift, leaving room for overhead presses, jumps, and medicine-ball throws.
- Target temperature and humidity for a strength facility?
- Temperature 68–78°F and humidity under 60%, supporting athlete safety and thermoregulation.
- NSCA target air-exchange rate for a facility?
- 8–12 times per hour, to remove heat, moisture, and odors from the training space.
- Recommended floor space per participant?
- About 100 ft2 per athlete, which reduces collision and injury risk during training.
- Maximum athletes per barbell or station?
- No more than 3 lifters per station or barbell, to limit crowding and waiting at peak times.
- Why locate a strength facility on the ground floor?
- A ground-floor location away from offices and classrooms limits noise and vibration complaints from heavy lifting and dropped loads.
- How is flooring matched to facility use?
- Rubberized or shock-absorbing flooring goes in the lifting area, with resilient surfaces under platforms to absorb dropped loads.
- Purpose of mirrors in a strength facility?
- Mirrors aid coaching technique feedback and extend the supervisor's sight lines across the floor for safety oversight.
- NSCA standard for supervision quality
- Direct supervision by a qualified professional within sight and sound of athletes, positioned for a clear, unobstructed line of sight to the whole floor.
- What belongs at the supervisor's station?
- Mirrors, an unobstructed view of the entire floor, and a phone for summoning EMS in an emergency.
- Max supervisor-to-athlete ratio for junior high?
- 1:10 or lower. Tighten further for novices, special populations, or complex lifts.
- Max supervisor-to-athlete ratio for high school?
- 1:15 or lower. Tighten for younger or less-experienced athletes.
- Max supervisor-to-athlete ratio for college/adult?
- 1:20 or lower. Tighten (e.g., 1:12) for higher-risk or explosive movements.
- When should you tighten supervision ratios?
- For younger, novice, or special-population athletes, or when training involves complex or explosive movements like power cleans.
- Most common negligence theme on this exam?
- Supervision failures — leaving a youth group unsupervised or exceeding a ratio during peak hours is the classic breach scenario.
- 28 high schoolers doing power cleans — min supervisors?
- The 1:15 ceiling gives 2, but power cleans are complex, so tighten toward 1:10 — about 3 supervisors. The exam rewards the safer staffing choice.
- Define standard of care
- The level of service a reasonably prudent, similarly credentialed professional would provide. Falling below it exposes the coach to negligence liability.
- What is negligence?
- Failure to meet the standard of care that causes harm. It requires all four elements — duty, breach, causation, and damages — to be present.
- Four elements of negligence
- Duty, breach, causation, and damages (harm). All four must hold; if any one is missing, there is no negligence.
- Negligence element: duty
- The legal obligation to provide a standard of care to the athlete — the first element that must be established.
- Negligence element: breach
- Failing to meet the owed standard of care, such as providing no supervision or unsafe equipment.
- Negligence element: causation
- The breach actually caused the athlete's injury — a direct link between the failure and the harm.
- Negligence element: damages
- Actual harm, injury, or loss suffered by the athlete; without real damages there is no negligence.
- Injury occurred but no duty was breached — negligent?
- No. Negligence requires all four elements. Harm alone without a breach of an owed standard of care means the answer is 'not negligent.'
- What is a waiver?
- A document signed before participation that releases the provider from liability for ordinary negligence. It is not a record of understanding.
- What is informed consent?
- A document confirming the athlete understood the activity's risks and procedures. It documents understanding but does NOT release liability.
- Waiver vs. informed consent — key difference
- A waiver releases the provider from ordinary-negligence liability; informed consent only documents that the athlete understood the risks. Consent is not a release.
- Who must clear an athlete before training begins?
- A health-care provider, via pre-participation screening and clearance, following governing-body rules (NCAA/NAIA for college, state associations for scholastic athletes).
- Purpose of pre-participation screening
- To identify risk before the first session — not after. Coaches may only train athletes who have completed provider screening and clearance.
- What is an Emergency Action Plan (EAP)?
- A written, venue-specific document listing personnel roles, communication method, AED/equipment locations, EMS access, and emergency contacts.
- How often must an EAP be reviewed?
- At least annually, and it should be rehearsed so staff can execute their roles quickly in a real emergency.
- Required EAP components
- Personnel roles, communication method, AED/equipment locations, EMS access directions (gate codes, entrance), emergency contacts, and review/rehearsal.
- Suspected spinal injury — correct action?
- Stabilize the athlete and summon EMS. Never move the athlete yourself when a spinal injury is suspected.
- What records defend against litigation?
- Informed consent, screening clearance, equipment inspection/maintenance logs, incident reports, and training logs — documentation proves you acted reasonably.
- How to handle unsafe equipment?
- Inspect equipment regularly and remove or tag out anything unsafe rather than leaving it in service. Failure to do so can be a breach of duty.
- Define validity in testing
- The degree to which a test actually measures what it is intended to measure (e.g., a vertical jump genuinely reflecting lower-body power).
- Define reliability in testing
- The degree to which a test produces consistent, repeatable results across trials when conditions are held constant.
- Define objectivity in testing
- Inter-rater reliability — the degree to which different testers obtain the same score for the same performance.
- Why does test order matter?
- Earlier tests must not fatigue later ones. Running max-effort tests too early invalidates the agility and power scores that follow.
- Standard order of athletic tests in one session
- Non-fatiguing tests, then agility, then maximum power and strength, then sprints, then local muscular endurance, then anaerobic and aerobic capacity last.
- Which tests come first in a session?
- Non-fatiguing tests — height, weight, body composition, and flexibility — because they don't deplete the athlete before performance tests.
- Where do agility tests fall in the sequence?
- Second — after non-fatiguing measures but before maximum power/strength, sprints, and endurance, so the athlete is still fresh.
- Where do capacity (endurance) tests fall?
- Last — anaerobic capacity then aerobic capacity at the end, because they are the most fatiguing and would contaminate every earlier test.
- Order: vertical jump, 1RM squat, pro-agility, 40-yd sprint
- Pro-agility first, then vertical jump and 1RM back squat (power/strength), then the 40-yard sprint last (no endurance test present).
- Electronic vs. hand timing — which reads slower?
- Electronic timing reads slower (longer) because it removes reaction-time lag, making it more accurate. Hand timing reads faster.
- Can you compare hand-timed and electronic sprint times?
- No. Never compare a hand-timed sprint to an electronically timed standard — hand timing reads artificially faster due to reaction-time lag.
- What is a field test?
- A practical performance test administered outside a lab (e.g., vertical jump, pro-agility) used to evaluate an athlete's fitness.
- What is the organizational environment?
- The chain of authority and mission a strength coach operates within — athletic director, sport coaches, sports medicine, and strength staff.
- Why know the organizational reporting lines?
- They tell you who clears athletes, who approves budgets, and who owns emergency decisions within the program's chain of command.
- What is scope of practice for a CSCS?
- Program design and coaching — NOT diagnosing injuries or prescribing rehabilitation, which belong to the medical staff.
- What credentials are part of the standard of care?
- Maintaining current certification plus CPR/AED and continuing education — staying competent is part of providing the standard of care.
- Best protection against litigation in this domain
- Written, posted, and consistently enforced policies and procedures — supervision rules, cleaning, equipment maintenance, and an EAP — applied uniformly.
- Why is record-keeping the 'connective tissue' here?
- Supervising at ratio, screening, inspecting equipment, and logging it both protect athletes and prove the coach met the standard of care.
- On supervision/negligence stems, which choice wins?
- The safer, more conservative staffing or response choice — not the bare-minimum ratio — especially with youth or complex/explosive lifts.
