Scientific disciplines
This domain tests integration of exercise physiology, biomechanics, motor control and learning, nutrition, and sport psychology into applied sport-science decisions. Expect items that ask for the most defensible interpretation, not isolated definitions.
Core rules
- Physiology: read VO2max, lactate threshold, movement economy, and substrate use against event duration and intensity; a high value is not automatically performance-limiting.
- Biomechanics: connect kinematics (joint angles, segment velocities) and kinetics (ground reaction force, impulse, rate of force development) to force-velocity qualities and tissue load.
- Motor learning: apply practice specificity, feedback scheduling, and transfer; more feedback is not always better.
- Nutrition and psychology: treat energy availability, fueling timing, arousal, and adherence as modifiable performance inputs.
Worked example
A sprinter's 30 m time plateaus despite rising back-squat strength. A force-velocity profile shows high estimated force (F0) but low theoretical velocity (V0). Reasoning: the limiter is velocity-oriented, so the program should emphasize maximal-velocity sprinting, wicket runs, and lighter high-velocity loading rather than more heavy squat volume. Verify with reliable electronic timing and video; track split times and jump metrics to confirm the intended adaptation.
Traps
- Answering from one discipline when the stem requires integration.
- Comparing laboratory and field measures as if identical.
- Ignoring training age, event demands, health status, or measurement error.
