Muscles are an integral part of functioning of human body. They are the providers of movement at more than 180 joints of our physical body. There have been a lot of discussion and research on the effects of yoga on muscular functions. We will try to assemble some of the facts on the topic, in this article, so as to bring to our readers a qualitative viewpoint towards the benefits of yoga.

Muscles are a collection of very small straps called fibers. Fibers are the contractile unit of a muscle, which is irritated through a nerve impulse from brain, and in response to that they respond as a whole, bringing about the contraction of the muscle. How many fibers are stimulated in a given activity determines the efficiency of performance.

Muscles are to be used constantly in order to keep them strong and fine tuned with the requirements of an individual. Active muscles allow the blood to be transfused through them deeper and maintain the level of nutrition of fibers, which are essentially made up of protein.

When we talk about training the muscles, there are generally two popular methods in the modern regime of workout, Endurance and Resistance training. First let's try and get a quick glimpse of what these are.

Endurance training: This method employs the workout which is primarily used for increasing the endurance and stamina. Activities like jogging, swimming, treadmill are some examples. These actions, when performed, engage the slow twitch fibers of muscles, which are generally meant for prolonged output in an aerobic environment, when enough oxygen is available for energy production in the muscles. It helps in increasing the efficiency level of fibers and makes them more resistance to fatigue.

Resistance training: Resistance training develops muscular strength and anaerobic endurance and increases the bulk of muscles. It employs fast twitch fibers which brings about a burst of quick action in a relatively anaerobic environment. This type of training is helps in improving the strength of muscles and ligaments, improves bone density, ensures cardiovascular health and manages the blood cholesterol. The training is done with the help of increased weight load on the muscles which improves the force production in the muscles and ability to sustain tension. Weight training is a popular method of resistance training. Sprinting is another effective method.

How yoga develops endurance:

First and foremost point is breathing. Practise of asanas is not complete without synchronizing the breathing patterns. This ensures a constant supply of oxygen for the body's requirement, thus activating the aerobic system. Yoga teaches us how to breathe appropriately in various physical movements in coordination with diaphragmatic and costal muscle involvement. Along with that we are encouraged to breathe slowly and deeply, which helps in the utilization of maximum lung capacity and also increases it overtime.

Asanas increases the endurance in that they require the use of body's strength in attaining several positions which are not falling under the normal ranges of movement in daily life. Slow paced practise while trying to cover the maximum range of our joints engages the muscles in a way that helps in improving their abilities to explore their inner potential and abilities. Flexor muscles are actively trained to sustain increased level of activity by holding the postures for long duration and the extensors at the same time are trained to avoid sending panic signals too quickly in an activity by lengthening them slowly and steadily over a long range of time. Asanas performed for a long duration of time with a steady rate of breath and maximum holding time and meditation sessions which are an integral part of yoga practise, not only improves physical but mental endurance as well. The dedication required for the practise, holding postures and letting go of fears of pain, helps clearing unnecessary Vrittis from the mind, and brings clarity and concentration due to channelization of efforts. Mediation at the same time centralizes the mental energies and help controlling the bizarre tendencies of mind to fluctuate. This strength of mind is essential in facing challenges and avoids stress in life.
