effect of yoga on muscular system

Impact of Yoga Asanas on Muscular SystemSome people are exploring the effects of yoga on the muscular system. Read some of the information I have gathered below from:


Yoga Asanas have a strengthening and toning impact on the muscular system of the human body. Yoga asanas are effective in countering problems of fitness as the practice of yoga postures improves physical health, mental peace and aids in spiritual growth.

Muscles get stronger and well toned if yoga asanas are practiced on regular basis. Asanas reduce the fat in the abdomen and waist. All the organs and cells of the body become active, thus increasing the immunity against diseases. The muscular system consists of almost five hundred muscles. The muscles not only cover the skeleton, but also occupy the deeper parts of the human body. The ‘skeletal muscles’ are made up of small, elongated, thread-like structures, called ‘muscular fibres’. The muscular coats of the stomach, the intestines and other such organs are made up of smoother muscular tissue.

When a muscle is working through yoga asanas, these tissues contract and consequently become shorter. The result is that the whole muscle is contracted and becomes shorter. When a muscle composed of fibres is at work, it not only becomes shorter but also thicker in the middle portion. This thickening of the muscle in the middle can best be felt and seen in the case of the biceps. This muscle crosses the upper arms in the front and its work is responsible for bending the forearms in the elbows. Yoga asanas strengthen the muscles of the body by effecting just such a rhythmic contraction and elongation.

Muscles that cover the skeleton bring about all the physical movements in the human body. A person can bring about any one of these movements at their own will simply because the muscles connected with these movements are under the control of the individual’s will. Thus, these muscles are called voluntary. There are other muscles, however, which cannot be contracted at the will of the individual. Their work is being done independent of the willpower and is called involuntary muscles. The best examples of involuntary muscles are those of the stomach, the intestines and the heart. The walls of arteries are also made up of involuntary muscles.
