The best is breaststroke in swimming, where the water provides a constant, even resistance to the movement of adduction. Examples of using Isokinetic contractions in the day-to-day and sporting activities are rare. To measure this a special piece of equipment known as an Isokinetic dynamometer is required. Isokinetic contractions are similar to Isotonic in that the muscle changes length during the contraction, where they differ is that Isokinetic contractions produce movements of a constant speed. Each muscle has an optimum length at which the maximum isometric force can be produced. The amount of force a muscle is able to produce during an isometric contraction depends on the length of the muscle at the point of contraction. There is no movement in the joints of the hand, but the muscles are contracting to provide a force sufficient enough to keep a steady hold on the racket. Another example is when you grip something, such as a tennis racket. This occurs when carrying an object in front of you as the weight of the object is pulling your arms down but your muscles are contracting to hold the object at the same level. Isometric contractions occur when there is no change in the length of the contracting muscle.
