GENERAL FITNESS ASSESSMENT :
Cardiovascular Endurance ( also known as VO2 max ):- Cardio vascular endurance, cardiovascular fitness, or aerobic fitness has been defined as the ability of the lungs, heart, and blood vessels to deliver adequate amounts of oxygen and nutrients to the cells to meet the demands of prolonged physical activity. As a person breathes, part of the oxygen contained in the air is absorbed in the lungs and transported to the heart by blood. The heart is then responsible for pumping the oxygenated blood through the circulatory system to all organs and tissues of the body. At the cellular level, oxygen is used to convert foods, primarily carbohydrates and fats, into energy necessary for physical activity, body functions, and to maintain a constant internal equilibrium.

Some examples of activities that promote cardiovascular or aerobic fitness are brisk walking, jogging, cycling, rowing, swimming, cross-country skiing, aerobic dance, soccer etc. A sound cardiovascular endurance program greatly contributes toward the enhancement and maintenance of good health.
Cardiovascular endurance is determined by the maximal amount of oxygen that the human body is able to utilize per minute of physical activity. This value is commonly expressed in milliliters of oxygen per kilogram of body weight per minute of physical activity (ml/kg/min). Since all tissues and organs of the body utilize oxygen to function, a higher amount of oxygen consumption indicates a more efficient cardiovascular system.

Step up and down on an 8 inch high box at a fast pace at a speed of 30 up/down in one minute. After one minute check the pulse. If he starts panting for breath, then he is required to improve his VO2 max (maximum volume of oxygen intake in one minute). He is therefore be advised some low level aerobic exercises like slow cycling or treadmill in the beginning.
