The deadlift is a very effective compound exercise for strengthening the lower back, but also exercises many other major muscle groups, including quads, hamstrings and abdominals. It is a challenging exercise, as poor form or execution can cause serious injury. [ 8 ]
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 ...
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] Many exercises such as the squat have several variations. Some studies have analyzed the differing muscle activation patterns, which can aid in exercise selection. [42]
"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 ...
The greatest benefit of moving an exercise onto an unstable surface is achieving a greater activation of the core musculature, exercises such as curl-up or push-up performed on an exercise ball. [13] An unstable surface increases activation of the rectus abdominis muscles (abdominals) and allows for greater activity per exercise when compared ...
The available oxygen and energy supply, and disturbances of muscle ion homeostasis are the main factors determining exercise performance, at least during brief very intense exercise. Each muscle contraction involves an action potential that activates voltage sensors, and so releases Ca 2+ ions from the muscle fibre's sarcoplasmic reticulum.
