Muscular endurance

Power
The product of strength x speed
Reaction time
The time taken for your body to respond to a certain stimulus
Strength
The ability to overcome resistance 4 different types 1. Maximal strength 2. Static strength 3. Dynamic strength 4. Explosive strength
Maximal strength
Greatest force possible in a single muscle contraction
Static strength
Amount of force exerted on an object you cannot move. The body is held in the same position and the muscle length stays the same.
Explosive strength
Amount of force exerted in one quick muscle contraction. (Closely linked with power)
Dynamic strength
Amount of force exerted repeatedly by a muscle. (Linked to muscular endurance)
Speed
The maximum rate at which an individual can perform a certain movement or cover a distance in a certain time.
Speed equation
