is the force that can be held in one place (force)
Static strength = Force
Strength is the weight that can be moved through a distance
(work), or the ability of muscle to generate force against a
Strength = Force x Distance
Example: 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 / Time
Example: 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 / Time
Example: 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.
Components are not discrete. Types of muscular endurance can
be seen as a continuum of characteristics. For example, swimming
requires components of continuous tension and repetitive dynamic
tension. Cycling is predominately a repetitive dynamic contraction
with slight continuous tension characteristics relative to running.
In addition, many training protocols designed for continuous
tension or repetitive dynamic contraction implement prolonged
intense contractions coupled with short rest periods.
Note: Components are not discrete. Types of muscular strength
can be seen as a continuum of characteristics. For example, slow
contractions during weight training incorporate components of
isometric contraction and dynamic contraction. In addition, all
power lifting exercises require certain muscles to be isometrically
contracted as well as dynamically contracted.
