The structural and functional independence of the muscular and skeletal systems. Network of bones, muscles, joints, and associated tissues (e.g., ligaments and tendons) of the body involved in the maintenance of body form and movement. The muscles, bones, and joints that form the moving structural frame of the body.  

Repetitive, submaximal muscular contractions measured by the time to fatigue and performed by the major muscle groups of the body.    

A tension or slight contraction of the muscle. The firmness of a muscle group in a relaxed state. A characteristic of a muscle brought about by the constant flow of nerve stimuli to that muscle, which describes its resistance to stretching. Abnormal muscle tone can be defined as: hypertonus (increased muscle tone, as in spasticity);…

An exercise that uses progressive tension-relaxation to reduce the effects of stress.  

The inability of muscle tissue to maintain a desired exercise intensity. The reduced capacity of a muscle to perform work as a result of repeated contractions and accumulation of lactic acid in anaerobic cell respiration. Fatigue may be partial or complete.  

A tearing away of a part of bone, usually by a tendon, ligament, or capsule.  

An electrical discharge associated with the activity of muscles.  

A postjunctional receptor for acetylcholine.
