Deck 1: Exercise Physiology, Bioenergetics (ATP-PC, Glycolysis, Oxidative) & Muscle Fiber Types (32 Cards — Basic)

What this deck covers: NASM CPT, ACE, and NSCA CSCS exercise physiology mastery covering the three metabolic energy systems (ATP-PCr, anaerobic glycolysis, oxidative phosphorylation), work-to-rest ratios, sliding filament theory, muscle spindles vs Golgi tendon organs, muscle fiber types (I, IIa, IIx), Fick equation, EPOC, RER, and ventilatory thresholds.

High-Yield Prompt / Question	Core Concept & Mechanism	Exam Application & Details
Compare the three metabolic energy systems (Phosphagen / ATP-PCr, Anaerobic Glycolysis, and Oxidative System) across fuel substrate, rate/capacity of ATP production, and primary activity duration.	1. Phosphagen (ATP-PCr): Uses stored ATP and Phosphocreatine (creatine kinase)	fastest rate of ATP production, lowest capacity; dominates 0–10 seconds of maximal power (1RM lift, 100m sprint). 2. Anaerobic Glycolysis: Breaks down blood glucose or muscle glycogen in sarcoplasm without oxygen; rapid ATP rate, intermediate capacity; dominates 15 seconds to ...
What are the NSCA CSCS recommended Work-to-Rest Ratios for training the Phosphagen (ATP-PCr), Fast Glycolytic, and Oxidative energy systems?	• Phosphagen (ATP-PCr) System (90–100% max power, 5–10s work): Work-to-rest ratio of 1:12 to 1:20 (full phosphocreatine resynthesis requires 3–5 minutes	50% replenished in ~30 seconds, 85–90% in 3 minutes). • Fast Glycolytic System (75–90% max power, 15–30s work): 1:3 to 1:5. • Fast Glycolytic + Oxidative (60–75% max power, 1–3m work): 1:3 to 1:4. • Oxidative System (<60% max power, >3m work): 1:1 to 1:3.
How many net ATP molecules are yielded from 1 molecule of blood Glucose vs. 1 glycosyl unit of Muscle Glycogen during Anaerobic Glycolysis and Complete Aerobic Oxidation?	• Anaerobic Glycolysis (cytoplasm): Yields 2 net ATP from 1 blood glucose molecule (requires 2 ATP investment at hexokinase and PFK) vs.	3 net ATP from muscle glycogen (glycogen phosphorylase bypasses hexokinase). • Complete Aerobic Oxidation (Glycolysis + Krebs Cycle + Electron Transport Chain): Yields ~32 ATP from 1 blood glucose vs. ~33 ATP from muscle glycogen.
What is the rate-limiting enzyme of each metabolic pathway: ATP-PCr, Glycolysis, Krebs (Citric Acid) Cycle, and the Electron Transport Chain?	• ATP-PCr system: Creatine Kinase (stimulated by elevated ADP, inhibited by elevated ATP).	• Glycolysis: Phosphofructokinase (PFK). • Krebs Cycle: Isocitrate Dehydrogenase. • Electron Transport Chain: Cytochrome Oxidase. All are allosterically stimulated by high ADP/AMP and inorganic phosphate (Pi), and inhibited by high ATP, NADH, or citrate.
Explain the fate of Pyruvate in Fast (Anaerobic) vs. Slow (Aerobic) Glycolysis, and describe the Cori Cycle.	When oxygen supply and mitochondrial capacity meet energy demand (Slow Glycolysis), pyruvate is transported into the mitochondria and converted by pyruvate dehydrogenase into Acetyl-CoA to enter the Krebs cycle.	When glycolytic flux exceeds mitochondrial capacity (Fast Glycolysis), Lactate Dehydrogenase (LDH) reduces pyruvate into Lactate (oxidizing NADH back to NAD+ so glycolysis can continue). In the Cori Cycle, blood lactate is transported to the liver and converted back into gluco...
Differentiate Onset of Blood Lactate Accumulation (OBLA) from the Lactate Threshold (LT), including their typical blood lactate concentrations.	• Lactate Threshold (LT / VT1): The exercise intensity at which blood lactate begins to accumulate above resting baseline levels (~1–2 mmol/L), occurring at 50–60% VO2max in untrained individuals and 70–80% VO2max in ...	• Onset of Blood Lactate Accumulation (OBLA / VT2): A second inflection point at a fixed blood lactate concentration of 4.0 mmol/L where lactate production rapidly exceeds clearance.
Describe the microscopic structure of the skeletal muscle Sarcomere (Z-disc, M-line, I-band, A-band, H-zone) and how each band changes during concentric contraction.	A sarcomere extends from Z-disc to Z-disc. • A-band (Anisotropic, dark): Entire length of thick Myosin filaments (with overlapping actin)	DOES NOT CHANGE LENGTH during contraction. • I-band (Isotropic, light): Thin Actin filaments only (straddling the Z-disc) + titin; SHORTENS during contraction. • H-zone: Central region of the A-band containing thick myosin filaments only (no actin overlap); SHORTENS/DISAPPEARS...
Outline the step-by-step molecular physiology of the Sliding Filament Theory and Excitation-Contraction Coupling.	1. Action potential travels down alpha motor neuron and releases Acetylcholine (ACh) across neuromuscular junction	2. Depolarization travels down T-tubules, triggering the Sarcoplasmic Reticulum (SR) to release Calcium ions (Ca2+); 3. Ca2+ binds to Troponin C, causing Tropomyosin to shift off the active binding sites on Actin; 4. energized Myosin heads bind Actin (forming cross-bridges) an...
What is a Motor Unit, what is the All-or-None Principle, and how does Henneman's Size Principle govern motor unit recruitment?	• Motor Unit: A single alpha motor neuron and all of the individual muscle fibers it innervates.	• All-or-None Principle: When a motor neuron fires an action potential, ALL muscle fibers within that specific motor unit contract maximally and simultaneously, or none do. • Henneman's Size Principle: Motor units are recruited in order from smallest to largest soma/axon diame...
Compare Type I, Type IIa, and Type IIx skeletal muscle fibers across contraction speed, force output, fatigue resistance, capillary/mitochondrial density, and predominant energy system.	• Type I (Slow-Twitch Oxidative): Slow contraction speed, low force/power, highest fatigue resistance, high capillary/mitochondrial/myoglobin density ('red fibers'), small motor neuron, aerobic oxidative system.	• Type IIa (Fast-Twitch Oxidative-Glycolytic / FOG): Fast contraction speed, high force/power, intermediate fatigue resistance, moderate mitochondrial/capillary density, uses both aerobic and anaerobic metabolism. • Type IIx (Fast-Twitch Glycolytic): Fastest contraction speed,...
Contrast the location, sensory stimulus, and reflex action of Muscle Spindles vs. Golgi Tendon Organs (GTOs).	• Muscle Spindles (intrafusal fibers parallel to extrafusal muscle fibers): Detect the MAGNITUDE and RATE OF LENGTH CHANGE (stretch).	When a muscle is rapidly stretched, the spindle fires via Ia afferents to trigger the Monosynaptic Stretch Reflex—contracting the stretched agonist muscle to prevent overstretching injury. • Golgi Tendon Organs (located in the musculotendinous junction in series with muscle fi...
Distinguish between Autogenic Inhibition and Reciprocal Inhibition in neuromuscular stretching (SMR, Static Stretching, and PNF).	• Autogenic Inhibition: Activation of the Golgi Tendon Organ within the SAME muscle being stretched or foam-rolled (sustained tension for >=30 seconds inhibits alpha motor neuron activity in that same tight muscle, al...	• Reciprocal Inhibition: Concentric contraction of the functional ANTAGONIST muscle sends inhibitory signals via spinal interneurons to relax the opposing target muscle being stretched (e.g., actively contracting the gluteus maximus to reciprocally inhibit and stretch a tight ...

Compare the Muscle Action Spectrum: Concentric, Eccentric, Isometric, and Isokinetic contractions, ranking them by maximal force capacity.	Force capacity ranking from highest to lowest: Eccentric > Isometric > Concentric. • Eccentric (lengthening under tension): Muscle develops tension while lengthening to decelerate gravity/external load (`Force < R...	produces the highest force (~20–40% greater than concentric) at the lowest metabolic ATP cost per unit of force. • Isometric (static stabilization): Muscle develops tension with no visible change in joint angle (Force = Resistance). • Concentric (shortening): Muscle develops...
Define the four Functional Roles of Muscles (Agonist, Antagonist, Synergist, Stabilizer) and provide the exact muscles for each role during a Barbell Bench Press and a Squat.	• Agonist (Prime Mover): Principal muscle producing the joint action. • Antagonist: Muscle acting in direct opposition to the agonist (relaxes via reciprocal inhibition). • Synergist: Assists the prime mover in perfor...	Synergists = Anterior Deltoid & Triceps Brachii; Stabilizer = Rotator Cuff; Antagonist = Posterior Deltoid / Middle Trapezius / Rhomboids. • Barbell Squat: Agonists = Gluteus Maximus & Quadriceps; Synergists = Hamstrings complex; Stabilizers = Transverse Abdominis & Erector Sp...
Explain Altered Reciprocal Inhibition and Synergistic Dominance, and give three classic clinical examples tested on the NASM CPT exam.	• Altered Reciprocal Inhibition: When a tight, overactive agonist muscle chronically decreases the neural drive to its functional antagonist, rendering the antagonist weak and underactive. • Synergistic Dominance: Whe...	2. Inhibited Gluteus Medius -> Tensor Fasciae Latae (TFL) becomes dominant in hip abduction (IT band syndrome); 3. Inhibited Lower Trapezius/Serratus -> Upper Trapezius & Levator Scapulae dominate shoulder elevation (impingement).
Compare First-Class, Second-Class, and Third-Class Levers (F-R-E / 1-2-3), including their Mechanical Advantage (MA = Moment Arm_F / Moment Arm_R) and human anatomical examples.	Mnemonic FLE-123 (what is in the middle: Fulcrum = 1st, Load/Resistance = 2nd, Effort/Force = 3rd): • First-Class Lever (E - F - R): Fulcrum lies between Effort and Resistance (e.g., Nodding the ...	MA can be >1 or <1. • Second-Class Lever (F - R - E): Resistance lies between Fulcrum and Effort (wheelbarrow; e.g., Standing Calf Raise where ball of foot/MTP joint is Fulcrum, body weight through ankle is Resistance, and Gastrocnemius/Soleus insertion on calcaneus ...
How is Torque (T) calculated biomechanically, and how does changing the Moment Arm during a Lateral Raise or Moving a Barbell Away from the Shins in a Deadlift alter joint torque?	Torque (T) = Force (F) x Moment Arm (d_perpendicular), where the Moment Arm is the shortest perpendicular distance from the joint's axis of rotation (fulcrum) to the line of action of the force (gravity).	During a free-weight Dumbbell Lateral Raise or Biceps Curl, resistance torque is maximal at 90 degrees of abduction/flexion because the horizontal moment arm from the joint to the vertical line of gravity is longest. During a Deadlift, allowing the barbell to drift forward...
Explain the Length-Tension Relationship of a sarcomere and how chronic postural adaptive shortening alters force production.	The Length-Tension Relationship states that there is an optimal resting sarcomere length (~100–120% of resting length, ~2.0–2.25 micrometers) at which the maximum number of actin-myosin cross-bridges can form, generat...	If a sarcomere is excessively shortened before contraction, actin filaments overlap and interfere with cross-bridge formation (active insufficiency). If a sarcomere is excessively stretched, there is minimal overlap between actin and myosin filaments, reducing active t...
Contrast the Force-Velocity Curve and the Power-Velocity Curve for Concentric vs. Eccentric muscle actions.	• Concentric Force-Velocity Relationship (Inverse): As the velocity of concentric muscle shortening INCREASES, the maximal force the muscle can generate DECREASES asymptotically (because fewer cross-bridges have time ...	Conversely, maximal concentric force occurs near zero velocity (isometric). • Power-Velocity Curve (Power = Force x Velocity): Peak mechanical power is NOT achieved at maximum force (where velocity = 0) nor at maximum velocity (where force ≈ 0), but at an intermediate veloci...
Define a Force-Couple Relationship and detail the exact muscles that form the Force-Couples for Scapular Upward Rotation, Scapular Downward Rotation, and Anterior/Posterior Pelvic Tilt.	A Force-Couple is the synergistic action of two or more muscles pulling in different linear directions to produce pure rotational torque around a joint: 1. Scapular Upward Rotation (essential for overhead shoulder...	Scapulohumeral Rhythm 2:1 GH to ST): Upper Trapezius (pulls superiorly/medially) + Lower Trapezius (pulls inferiorly) + Serratus Anterior (pulls laterally/anteriorly around ribcage). 2. Scapular Downward Rotation: **Rhomboids + Levator Scapulae + Pectoralis Min...
Compare Open-Kinetic-Chain (OKC) and Closed-Kinetic-Chain (CKC) exercises, and compare patellofemoral vs. tibiofemoral ACL shear stress in a Leg Extension vs. a Squat.	• Open-Kinetic-Chain (OKC): The distal segment (hand or foot) is free to move in space (e.g., Seated Leg Extension, Bench Press, Lat Pulldown)	allows isolated single-joint muscle targeting. • Closed-Kinetic-Chain (CKC): The distal segment is fixed against an immovable or heavy surface (e.g., Squat, Deadlift, Push-Up, Pull-Up); requires simultaneous multi-joint co-contraction and enhances joint compression/propriocept...
Compare the NASM Local Stabilization System, Global Stabilization System, and Movement System of the lumbo-pelvic-hip complex (core).	1. Local Stabilization System (deep muscles attaching directly to vertebrae	rich in Type I fibers and muscle spindles; provide intersegmental spinal stiffness via feed-forward activation before limb movement): Transverse Abdominis (TVA), Internal Obliques, Multifidus, Pelvic Floor, and Diaphragm. 2. Global Stabilization System (transfer loads ...

Overactive (Shortened): Soleus, lateral gastrocnemius, biceps femoris (short head), and tensor fasciae latae (TFL).	Underactive (Lengthened): Medial gastrocnemius, medial hamstring complex (semimembranosus/semitendinosus), gracilis, sartorius, popliteus, and posterior tibialis.
In the Overhead Squat Assessment (OHSA — Anterior View), what overactive and underactive muscles cause the Knees to Move Inward (Dynamic Knee Valgus)?	Overactive (Shortened): Adductor complex, biceps femoris (short head), TFL, lateral gastrocnemius, and vastus lateralis.	Underactive (Lengthened): Gluteus medius, gluteus maximus, vastus medialis oblique (VMO), medial hamstrings, and medial gastrocnemius.

Overactive (Shortened): Soleus, gastrocnemius, hip flexor complex (iliopsoas, rectus femoris), and abdominal complex (rectus abdominis, external obliques).	Underactive (Lengthened): Anterior tibialis, gluteus maximus, and erector spinae.
In the Overhead Squat Assessment (OHSA — Lateral View), what overactive and underactive muscles cause the Low Back to Arch (Anterior Pelvic Tilt)?	Overactive (Shortened): Hip flexor complex (iliopsoas, rectus femoris, TFL), erector spinae, and latissimus dorsi.	Underactive (Lengthened): Gluteus maximus, hamstring complex, and intrinsic core stabilizers (transversus abdominis, multifidus, internal obliques).
In the Overhead Squat Assessment (OHSA — Lateral View), what overactive and underactive muscles cause the Arms to Fall Forward?	Overactive (Shortened): Latissimus dorsi, teres major, pectoralis major, and pectoralis minor.	Underactive (Lengthened): Middle and lower trapezius, rhomboids, and rotator cuff (infraspinatus, teres minor, supraspinatus).
How is the Single-Leg Squat Assessment performed, and what compensation is primarily evaluated?	The client stands on one leg with hands on hips, eyes focused straight ahead, and squats to a comfortable depth for up to 5 repetitions per leg.	Primary compensation assessed: Knee moving inward (dynamic knee valgus), indicating overactive adductors/TFL and underactive gluteus medius/maximus.
What compensations are evaluated during the Pushing and Pulling Movement Assessments?	1. Low back arches (overactive hip flexors/erector spinae	underactive intrinsic core stabilizers); 2. Shoulders elevate (overactive upper trapezius, sternocleidomastoid, levator scapulae; underactive middle/lower trapezius); 3. Head migrates forward / juts out (overactive upper trapezius, sternocleidomastoid, levator scapulae; undera...
State the Karvonen Formula (Heart Rate Reserve method) for calculating Target Heart Rate (THR) and provide a worked example.	THR = [(HRmax - HRrest) x %Intensity] + HRrest, where HRmax is estimated via Tanaka formula (208 - [0.7 x Age]) or 220 - Age. Example: Age 40 (HRmax = 180 bpm), HRrest = 60 bpm, 70% intensity: HRR = 180 - 60 = 120	120 x 0.70 = 84; THR = 84 + 60 = 144 bpm.
Compare the three NASM Cardiorespiratory Training Zones (Zones 1, 2, and 3) by %HRmax and Ventilatory Threshold landmarks.	Zone 1 (Recuperative/Aerobic Base): 65–75% HRmax (below VT1	client can speak comfortably in full sentences). Zone 2 (Aerobic Efficiency/Threshold): 76–85% HRmax (between VT1 and VT2; speaking becomes challenging). Zone 3 (Anaerobic/Peak Work): 86–95% HRmax (above VT2; client can speak only 1–2 words at a time).
How is the Talk Test used to identify Ventilatory Threshold 1 (VT1) and Ventilatory Threshold 2 (VT2) in the field?	VT1 represents the point where ventilation increases non-linearly relative to oxygen uptake and blood lactate begins to rise above resting levels	identified when continuous conversation first becomes noticeably uncomfortable. VT2 (Respiratory Compensation Point / OBLA) is where lactate accumulates rapidly faster than clearance; speaking more than a few words is impossible.
Describe the protocol and clinical utility of the YMCA 3-Minute Step Test.	The client steps up and down on a 12-inch (30.5 cm) step for 3 continuous minutes at a cadence of 96 beats per minute (24 steps/minute).	Within 5 seconds of completion, the radial pulse is counted for 60 full seconds (Recovery Heart Rate) and compared against age/sex norms to classify cardiorespiratory fitness and assign starting HR zones.
Describe the protocol and purpose of the Rockport One-Mile Walk Test.	The client walks 1 mile (1.6 km) as fast as possible on a flat track. Immediately upon finishing, completion time and post-exercise heart rate are recorded. Using body weight, age, sex, walk time, and heart rate, VO2m...	ideal for sedentary, older, or overweight individuals.

(Or via the Epley 1RM formula: 1RM = Weight x [1 + (Reps / 30)]).
Describe the three phases of the Stretch-Shortening Cycle (SSC) in Plyometric Exercise.	Phase I (Eccentric Phase): Pre-stretching of the agonist muscle stores elastic energy in the Series Elastic Component (SEC — tendons) and stimulates muscle spindles. Phase II (Amortization / Transition Phase): Brief e...	MUST be kept as short as possible so stored elastic energy is not dissipated as heat. Phase III (Concentric Phase): Stored elastic energy + stretch reflex potentiate explosive concentric force.
Describe the two models of Plyometric Potentiation: the Mechanical Model (Series Elastic Component) and the Neurophysiological Model (Stretch Reflex).	Mechanical Model: Rapid eccentric stretch stores potential elastic energy primarily in musculotendinous structures (Series Elastic Component)	during a rapid concentric contraction, this elastic recoil adds to active muscle force. Neurophysiological Model: Rapid stretch deforms intrafusal muscle spindles, sending Ia afferent signals to the spinal cord that synapse directly on alpha motor neurons to increase agonist m...
What are the NSCA CSCS prerequisites, foot contact volume limits, and recovery intervals for Lower-Body Plyometric Training?	Readiness guidelines: High-intensity lower-body plyometrics (such as depth jumps) traditionally favor athletes with strong relative lower-body strength (e.g., 1RM back squat >= 1.5x body weight) and solid landing mech...	Intermediate = 100–120; Advanced = 120–140. Rest between sessions: 48–72 hours; work-to-rest ratio: 1:5 to 1:10.
Rank Lower-Body Plyometric drills from Lowest Intensity to Highest Intensity, and specify recommended Depth Jump box heights.	Intensity Progression (Low -> High): 1. Jumps-in-place (two-foot ankle hop, squat jump)	2. Standing jumps (standing long jump, vertical jump); 3. Multiple hops and jumps (double-leg hops, front barrier hops); 4. Bounds (exaggerated horizontal/vertical stride length); 5. Box drills (jump to box, jump from box); 6. Depth jumps (16–42 inches / 41–107 cm; 16–32 inche...
Outline the sequential biomechanical phases of the Power Clean / Clean and Jerk (First Pull, Transition, Second Pull, Catch).	1.	First Pull (Floor to knees): Lifter extends knees and hips while maintaining a constant torso angle to the floor and keeping the barbell close to the shins. 2. Transition / Scoop (Around the knees): Knees re-bend slightly as hips move forward under the bar to re-establish the ...
What is Triple Extension, and which athletic movements share its biomechanical signature?	Triple Extension is the simultaneous, explosive extension of the Hip (gluteus maximus, hamstrings), Knee (quadriceps), and Ankle — Plantarflexion (gastrocnemius, soleus).	It is the core biomechanical engine of the Second Pull in Olympic weightlifting (Snatch, Clean, Push Jerk), vertical jumping, broad jumping, and sprint acceleration.
Compare the grip techniques used in Olympic Weightlifting and Powerlifting: Hook Grip, Alternated (Mixed) Grip, and Pronated/Supinated Grips.	Hook Grip (Olympic lifts — Snatch & Clean): Pronated grip where the index and middle fingers wrap over and trap the thumb against the barbell, preventing bar roll without creating rotational torque on the spine/biceps.	Alternated / Mixed Grip (heavy Deadlifts): One hand pronated, one hand supinated (prevents bar roll, though places slight supinated-arm biceps tendon stress).
State the NSCA CSCS Spotting Rules for Free-Weight Exercises (Overhead, Over-the-Face, On-the-Back, and Power Exercises).	1. Over-the-Face Exercises (Bench Press, Lying Triceps Extension): Spotter grasps the bar directly using an alternated grip inside the lifter's hands. 2. Overhead & On-the-Back Exercises (Back Squat, Front Squat, Shou...	use 2 spotters at ends of bar for heavy loads) or wrists. 3. Power / Explosive Exercises (Power Clean, Snatch, Push Jerk): NEVER spot! Instead, clear the platform; the lifter drops the bar forward (or jumps forward if bar goes behind).
What is the recommended Exercise Order within a Resistance Training session (NSCA CSCS guidelines)?	1. Power / Olympic Exercises First (Snatch, Power Clean, Push Jerk, Plyometrics — highest neural demand and fatigue sensitivity)	2. Other Core (Multi-Joint) Exercises (Back Squat, Deadlift, Bench Press, Bent-Over Row); 3. Assistance (Single-Joint) Exercises Last (Biceps Curl, Triceps Pushdown, Leg Extension, Hamstring Curl). Alternately: Upper/Lower body alternation or Push/Pull supersets.
What is the NSCA 2-for-2 Rule for progressive overload load increases, and what are the standard load increments?	2-for-2 Rule: If an athlete can perform 2 or more repetitions over their assigned repetition goal in the last set of an exercise for 2 consecutive workouts, weight should be added to that exercise for the next trainin...	Larger Athlete /Upper Body = 5–10 lb (2.5–5 kg); Smaller Athlete / Lower Body = 5–10 lb (2.5–5 kg); Larger Athlete / Lower Body = 10–15+ lb (5–7.5+ kg).

Deck 6: Sports Nutrition: Macronutrients (g/kg Guidelines), Hydration, Ergogenic Aids & Energy Balance (32 Cards — Advanced)

What this deck covers: ISSN, ACSM, and NSCA CSCS sports nutrition mastery covering carbohydrate, protein, and lipid g/kg/day targets, sweat rate and electrolyte rehydration, evidence-based ergogenic aids (creatine, caffeine, beta-alanine, nitrates, sodium bicarbonate), RED-S, and nutrient timing.

High-Yield Prompt / Question	Core Concept & Mechanism	Exam Application & Details
What are the Atwater Energy Factors (kcal/gram) and Acceptable Macronutrient Distribution Ranges (AMDR) for Carbohydrate, Protein, Fat, and Alcohol?	Caloric Density (kcal/g): Carbohydrate = 4 kcal/g	Protein = 4 kcal/g; Lipid (Fat) = 9 kcal/g; Alcohol (Ethanol — non-essential) = 7 kcal/g. Acceptable Macronutrient Distribution Ranges (AMDR — Institute of Medicine): Carbohydrates = 45–65% of total daily kcal; Fats = 20–35% of total kcal (with < 10% from saturated fat); Prote...
What are the daily Protein intake recommendations (g/kg/day) for the General Population, Endurance Athletes, Strength/Power Athletes, and Caloric-Deficit Athletes?	1.	Sedentary Adult RDA: 0.8 g/kg/day (minimum to prevent deficiency). 2. Aerobic Endurance Athletes: 1.2–1.4 (up to 1.6) g/kg/day. 3. Strength, Power & Hypertrophy Athletes: 1.6–2.2 g/kg/day. 4. Athletes in a Hypocaloric Deficit (Cutting while preserving Lean Body Mass): 2.2–2.7+...
What is the role of the Essential Amino Acid Leucine (the 'Leucine Trigger') in stimulating Muscle Protein Synthesis (MPS)?	There are 20 standard amino acids, 9 of which are Essential Amino Acids (EAAs: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine), including the 3 Branched-Chain Amino Ac...	however, all 9 EAAs are required as building blocks to sustain MPS.
What are the daily Carbohydrate intake recommendations (g/kg/day) across training volumes and intensities (ACSM / ISSN)?	1.	Light / Skill-Based Activity: 3–5 g/kg/day. 2. Moderate Exercise (~1 hour/day) or Strength/Sprint Athletes: 5–7 g/kg/day. 3. Moderate-to-High Intensity Endurance (1–3 hours/day): 6–10 g/kg/day. 4. Extreme Endurance (> 4–5 hours/day, e.g., Tour de France / Ironman) or Carbohydr...
Compare the Glycemic Index (GI) and Glycemic Load (GL), including how each is calculated and applied around exercise.	Glycemic Index (GI): Ranks how rapidly 50g of digestible carbohydrate from a food raises blood glucose over 2 hours compared to 50g of pure glucose (or white bread = 100)	Low GI <= 55, Medium GI = 56–69, High GI >= 70. Glycemic Load (GL): Accounts for actual serving size: GL = (GI x Grams of Carbohydrate per serving) / 100 (Low GL <= 10, Medium 11–19, High >= 20). High-GI carbs (sports drinks, white rice, dextrose) are ideal during exercise and...
What are the pre-exercise, intra-exercise, and post-exercise Carbohydrate and Protein timing guidelines?	Pre-Exercise (1–4 hours prior): 1–4 g/kg carbohydrate + 0.15–0.25 g/kg protein (low fiber, low fat to prevent GI distress). Intra-Exercise: < 45 min = none needed	45–75 min = carbohydrate mouth rinse; 1–2.5 hours = 30–60 g/hour of glucose/maltodextrin; > 2.5 hours ultra-endurance = up to 90 g/hour using Multiple Transportable Carbohydrates (2:1 Glucose:Fructose ratio via SGLT1 and GLUT5 transporters). Post-Exercise (when < 8h recovery):...
How do you calculate an athlete's Sweat Rate, what percentage of body weight loss from dehydration impairs performance, and how much fluid must be consumed post-exercise?	Sweat Rate = (Pre-Exercise Weight - Post-Exercise Weight + Fluid Consumed - Urine Volume) / Exercise Duration.	Performance Impairment Threshold: Dehydration exceeding >= 2% of body weight (e.g., 1.6 kg in an 80-kg athlete) significantly degrades aerobic endurance, thermoregulation, cognitive function, and stroke volume (cardiovascular drift). Post-Exercise Rehydration Rule: Drink 1.25 ...
What is the optimal composition of an Oral Rehydration / Sports Drink (% carbohydrate and electrolytes) during prolonged exercise?	A 6–8% Carbohydrate solution (6–8 grams of carbohydrate per 100 mL, or 14–19 g per 8 fl oz / 240 mL) with 20–30 mEq/L Sodium (460–690 mg/L) and 2–5 mEq/L Potassium.	Solutions > 8–10% carbohydrate (like soda or undiluted fruit juice) slow gastric emptying and pull water into the intestinal lumen via osmosis, causing cramping and diarrhea.
What is Exercise-Associated Hyponatremia (EAH), what causes it, and how is it prevented?	Exercise-Associated Hyponatremia (EAH) is a potentially fatal dilution of blood serum sodium concentration below < 135 mmol/L (severe if < 125–130 mmol/L), leading to cerebral edema, headache, nausea, confusion, seizu...	include sodium in fluids.
Explain the mechanism of action, dosing protocols (Loading vs. Maintenance), and documented benefits of Creatine Monohydrate.	Mechanism: Increases intramuscular total creatine and Phosphocreatine (PCr) stores by 15–40%, accelerating ATP resynthesis via the creatine kinase reaction during high-intensity bouts and enhancing satellite cell/cell...	Maintenance Phase = 3–5 g/day (or 0.03 g/kg/day) continuously. Benefits: Increases 1RM strength, repetitive sprint power, lean body mass (initial 1–2 kg gain from intracellular water), and glycogen storage.
Explain the mechanism of action, optimal dosing, and timing of Caffeine as an ergogenic aid.	Mechanism: Competitive antagonist of central Adenosine (A1 and A2A) receptors in the brain, reducing perceived exertion (RPE) and pain while increasing motor unit recruitment and catecholamine release. Optimal Dosing ...	doses >= 9 mg/kg do not further increase performance and cause anxiety, tremors, tachycardia, and GI distress).
Explain the mechanism of action, dosing protocol, and common side effect of Beta-Alanine supplementation.	Mechanism: Beta-alanine is the rate-limiting precursor (combined with L-histidine) for synthesizing intramuscular Carnosine, an intracellular dipeptide buffer that sequesters hydrogen ions (H+) produced during high-in...	Dosing: 4 to 6 g/day divided into 0.8–1.6g doses for at least 2–4 weeks (increases muscle carnosine by 40–80%). Side Effect: Harmless transient skin tingling (paresthesia), minimized by split dosing or sustained-release tablets.
