Closed chain exercises are often compound movements, that generally incur compressive forces, while open-chain exercises are often isolation movements that promote more shearing forces. [ 1 ] CKC exercises involve more than one muscle group and joint simultaneously rather than concentrating solely on one, as many OKC exercises do (single-joint ...
However, single-joint exercises can result in greater muscle growth in the targeted muscles, [40] and are more suitable for injury prevention and rehabilitation. [39] Low variation in exercise selection or targeted muscle groups, combined with a high volume of training, is likely to lead to overtraining and training maladaptation. [ 41 ]

The opposite of OKC are closed kinetic chain exercises (CKC). Both are effective for strengthening and rehabilitation objectives. [1] Closed-chain exercises tend to offer more "functional" athletic benefits because of their ability to recruit more muscle groups and require additional skeletal stabilization. [2]
Case reports of rehabilitation programs for patients with PSP generally include limb-coordination activities, tilt-board balancing, gait training, strength training with progressive resistive exercises, and isokinetic exercises and stretching of the neck muscles. [50]
An isometric exercise is an exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term "isometric" combines the Greek words isos (equal) and -metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction ...
Inclusion of isokinetic quadriceps and hamstring strengthening exercises into the rehabilitation packages for the patients with knee osteoarthritis may also enhance the high-quality of life and make a contribution to the decreased hazard of fall.
The athlete usually sinks (drops) too low which takes too long to make the transition from the eccentric to the concentric contraction. As a result, the exercise becomes a jump-strength exercise and not a true plyometric one. Jump technique remains the same regardless of whether it is a true plyometric exercise or a jump exercise.
