What type of exercise involves resistance given at a fixed velocity of movement?

Isokinetic exercise refers to a type of resistance training where the speed of movement remains constant throughout the entire range of motion. This means that the resistance is adjusted according to the amount of force applied by the individual, allowing for maximum effort at a predetermined velocity. This is particularly useful in rehabilitation and strength training, as it focuses on increasing strength without putting excessive strain on the joints. The controlled nature of isokinetic exercise allows for safe and effective training, leading to improved muscle function and performance.

In contrast, isometric exercises involve muscle contraction without any movement of the joint angle, while plyometric exercises focus on explosive movements that utilize the stretch-shortening cycle of muscles. Body weight exercises primarily rely on an individual's own weight for resistance, without the control of velocity that is characteristic of isokinetic exercises.
