Question

tensing of the muscles that does not involve joint movement is called:
a: Isometric stretching
b:static stretching
c:isotonic stretching
d: PNF strtching

Answer 1

Static stretching is used to stretch muscles while the body is at rest. It is composed of various techniques that gradually lengthen a muscle to an elongated position (to the point of discomfort) and hold that position for 30 seconds to two minutes. 30 seconds is the minimum duration to get the benefits of stretching, whereas two minutes is the maximum (if a position can be held for more than two minutes, a farther stretch should be performed). During this holding period or directly afterwards, participants may feel a mild discomfort or warm sensation in the muscles. Static stretching exercises involve specialized tension receptors in our muscles
