Speed-Strength

Speed-Strength: Speed training where there is relatively more contribution from acceleration than force. Speed-strength training uses lower intensities than power training or strength-speed training and has its greatest effect on rate of force development rather than maximum strength

Isokinetic Muscle Action

Isokinetic Muscle Action: Muscle contraction against a resistance that moves at a constant velocity, so that the maximum force of which the muscle is capable throughout the range of motion can be applied. This means, theoretically, that the muscle shortens or lengthens at a constant velocity whereas, normally, muscles shorten or lengthen at various rates and tension throughout a movement, as the joint angle changes. Isokinetics are used primarily for testing purposes.

Equilibrium

Equilibrium is the state of a system that is not changing its speed or direction. At rest it is called static equilibrium and during movement it is called dynamic equilibrium. Equilibrium is often used interchangeably with balance but balance is the process of controlling movement during short or long periods rather than the the unchanging state itself, which is equilibrium.
