Strength, Power, Speed, etc.


Static strength is the force that can be held in one place (force)Static strength = ForceExample: isometrics
Strength is the weight that can be moved through a distance (work), or the ability of muscle to generate force against a resistanceStrength = Force x DistanceExample: competitive powerlifting (a misnomer)
Power is the product of a force and the speed (power). Power can be expressed by the work achieved in a unit time (asymptotic). Power is a combination of strength and speed.Power = Force x Distance / TimeExample: Olympic style weightlifting (strength dominated power), shot-put or jump (speed dominated power)
Speed is the distance traveled per unit time without regard to direction (speed)Speed = Distance / TimeExample: sprinting, running
Velocity is the speed and direction of an entity (velocity)Velocity = Speed and direction
Muscular Endurance = ability to perform repetitive or sustained muscular contractions against some resistance for and extended period of time.
