taken from the atmosphere with the help of nose and mouth and is sent to the lungs and from where it is transferred to the blood. Transportation of oxygen from lungs to the target muscle is very important. How much oxygen will be transported depends upon the amount of oxygen absorbed by the blood and the capacity of the heart which will pump the blood into circulation. The amount of oxygen absorbed in blood depends upon the amount of haemoglobin present in the blood which carries oxygen to the target muscles. The capacity of the heart and vascular system of the body will determine how fast the blood will reach to the target muscle. If the heart is strong and has larger chamber size, it will pump more blood in circulation which will help the oxygen to reach the target muscle in less time. Further, when the oxygen reaches the target muscle, it has to be taken up by the muscle and then consumed. . Anaerobic capacity: It is the ability of the muscle to work in the presence of inadequate amount of oxygen. During such conditions, two types of energy systems work, i.e., splitting of phosphogens and glycolysis of glycogens. The phosphogens, i.e., Adenosine
