While performing isotonic exercise, the muscle length is shortened with constant tension or weight. On the other hand, while performing isometric exercise, the muscle length does not change as ...

There are two phases of isotonic exercises: concentric and eccentric. During the concentric phase, the primary working muscles shorten as tension rises to meet resistance — think of it as the ...

Muscles contract in different ways to produce a range of movements: Isotonic contraction – involves the muscle producing tension and controlling the speed of the muscular contraction.

Isotonic eccentric contraction – this involves the muscle lengthening whilst it is under tension. The origin and the insertion move further away from each other. An eccentric contraction ...
