Biomechanics
The point around which a lever rotates.
Axis (fulcrum)
The class of lever used when standing on tiptoes.
Second‑class lever
The mental skill that involves imagining successful performance.
Visualisation
Whats the principle that training must match the sport or skill
Specificity
Whats the method involving repeated short bursts of high intensity with rest.
Interval training
The force that opposes motion and helps with grip.
Friction
Why follow‑through improves accuracy in throwing
Extends time force is applied
The type of motivation driven by internal satisfaction.
Intrinsic motivation
The principle that training must gradually increase over time.
Progressive overload
Whats the method used to improve muscular strength and power.
Resistance training
What is Newton’s law that explains why a sprinter accelerates faster when applying more force
Newton’s Second Law
The optimal angle of release for maximum projectile distance (general rule).
Around 45°
A short, positive phrase athletes repeat to stay focused.
Self‑talk
The principle that fitness decreases when training stops.
Reversibility
The method involving continuous, steady‑state exercise.
Continuous training
Whats the factor that increases when an athlete widens their base of support.
Stability
whats the type of drag swimmers try to reduce by shaving or wearing smooth suits.
Surface drag
The level of arousal needed for best performance (general concept).
Optimal arousal / Inverted‑U theory
The principle that training must be varied to avoid plateaus.
Variety
The method that alternates stations targeting different components.
Circuit training
Whats the biomechanical reason a longer lever (e.g., tennis racquet) increases hitting speed.
Greater radius of rotation → higher end‑point velocity
How centre of gravity affects balance in a handstand.
Must stay directly above the base of support (hands)
The psychological strategy used to control nerves before competition.
Arousal regulation (e.g., breathing, centering)
Whats the principle that training must be tailored to the individual.
Individuality
The method that improves flexibility through slow, controlled stretching.
Static stretching
