What kind of exercise involves exerting as much force as possible against a resistance that moves at a more or less constant speed?

isokinetic exercise

Explanation:

In the method of isokinetic work, 6 to 20 repetitions series are used as a rule for each muscle group, making maximum muscular efforts of each angle of movement so that advantages can be obtained, taking advantage of the best of this training method, which is to provide resistance proportional to the applied force of each angle of motion, a fact that does not occur in isotonic and isometric methods. It is important to say that strength training with the isokinetic method is intended to improve strength in general and strength endurance. When we work, with the aim of seeking muscular strength, the best form of evaluation and training is isokinetic.

For a better understanding, we can define "muscular strength" as the maximum amount of force that a muscle can generate in a specific pattern of movement and at a certain speed of movement.

Currently, in primary strength training programs, contractions are found that begin with the elongated muscle and muscular effort is exerted to shorten the muscle. These contractions are called concentric. Muscle contraction is eccentric when the muscle lengthens during contraction. That is, during the development of active voltage.
