MUSCLE PHYSIOLOGY

Detailed explanation-1: -Concentric contractions may be isokinetic or isotonic. Isokinetic exercise attempts to combine the best features of both isometrics and weight training. It provides muscular overload at a constant preset speed while a muscle mobilizes its force through the full range of motion.

Detailed explanation-2: -Isokinetic contractions are those in which there is a consistent rate of speed. Isotonic contractions are those in which there is consistent tension as the muscle length changes. These can be either concentric (muscle shortening) or eccentric (muscle elongation).

Detailed explanation-3: -During isokinetic contractions a muscle shortens at constant speed (or constant angular velocity) over the full range of motion. During a full isokinetic contraction, the tension developed by a muscle is at its maximum throughout its whole range.

Detailed explanation-4: -Isokinetic-or “same speed”-exercise refers to movement at a constant speed regardless of the amount of resistance applied. Muscles contract at a constant speed in isokinetic contraction. This consistency allows muscles to gain strength uniformly all through the range of movement.
