Isotonic contractions differ from isokinetic contractions in that in isokinetic contractions the muscle speed remains constant. While superficially identical, as the muscle's force changes via the length-tension relationship during a contraction, an isotonic contraction will keep force constant while velocity changes, but an isokinetic ...
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 ...
Depiction of smooth muscle contraction. Muscle contraction is the activation of tension-generating sites within muscle cells. [1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position.

A gym where various forms of strength training are being practiced. From left: overhead presses, battle ropes, planking, and kettlebell raises. Strength training, also known as weight training or resistance training, is a form of exercise aimed at improving physical strength.
Open chain exercises are postulated to be advantageous in rehabilitation settings because they can be easily manipulated to selectively target specific muscles, or specific heads of certain muscles, more effectively than their closed chain counterparts, at different phases of contraction.
This is a compound exercise that also involves the triceps and the front deltoids, also recruits the upper and lower back muscles, and traps. The bench press is the king of all upper body exercises and is one of the most popular chest exercises in the world. It is the final exercise in 'The big 3'.
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 ...
Isometric exercise devices perform exercises or strength test using static contraction of a muscle without any visible movement in the angle of the joint. This is reflected in the name; the term "isometric" combines the prefix "iso" (same) with "metric" (distance), meaning that in these exercises the length of the muscle does not change, [1] as compared to isotonic contractions ("tonos" means ...
