Exercise Physiology and Applied Movement Analysis Flashcards
Speed equation
distance / time
Velocity equation
displacement / time
Acceleration equation
change in velocity / time taken
Friction Definition
Contact force acting on surfaces opposing motion
Factors Affecting Friction
Surface area
Force applied
Molecular interaction
Air Resistance Definition
Form of fluid friction
Factors Affecting Air Resistance
Velocity
Frontal cross-sectional Area
Surface Characteristics
Maximise Horizontal Displacement
Force applied
Angle / Trajectory
Height of Release
Momentum Equation
velocity x mass
Angular Momentum
angular velocity x moment of inertia
A larger moment of inertia results in …
Lower angular velocity to conserve angular momentum
Bernoulli Principle
When an object has a pressure gradient of air surrounding it. For lift- lower pressure on top and higher pressure underneath.
lower pressure - faster fluid
Magnus Effect
Due to Bernoulli
Only for spinning objects
Due to one side of air flow moving faster (with direction) and the other side pushes the oncoming airflow causing turbulence
Momentum
The amount of energy an object possesses
strategies to speed up recovery
cryotherapy - liquid nitrogen cold
compression clothes - decreases swelling/ water retention
ice baths- stimulation of muscle cell activity
massage- target after 2 hrs, increase recovery time, reduce inflammation
