ROM- the normal amount your joints can be moved in certain directions.
Fast twitch muscles-better at generating short bursts of energy and power
Slow twitch muscles- more efficient at using oxygen to convert to energy. Longer lasting and fatigue less
Isometric- a type of strength training in which the joint angle and muscle length do not change during contraction
