"Dynamic Tension" is the name Charles Atlas gave to the system of physical exercises that he first popularized in the 1920s. Dynamic Tension is a self-resistance exercise method which pits muscle against muscle. The practitioner tenses the muscles of a given body part and then moves the body part against the tension as if a heavy weight were ...
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 ...
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 ...
At one point or another, we’ve all experienced the unexpected, intense pain of a muscle cramp.. Muscle cramps, also known as muscle spasms or charley horses, are the involuntary contraction of ...
There is a BMU for each mode of muscle contraction, including: isometric (muscle contraction at a fixed length, i.e. no movement), isotonic concentric (muscle shortens as it contracts at a constant torque), isokinetic concentric (muscle shortens as it contracts but at a constant velocity), isotonic and isokinetic eccentric (muscle extended).
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]
