INTRODUCTION

Physical activity is defined as movement of body, which is produced by the skeletal muscles of the body which results in energy expenditure. There are several numbers of techniques for the assessment of physical activity related energy expend, the most valid technique to estimate this value at the definition of the physical activity is indirect calorimetry (Westerterp, 2013). Oxygen consumed during postexercise recovery period and during exercise above resting level contribute to calorie expenditure. The physiology of upperbody exercise and lower body exercise has been thoroughly researched and reviewed in so many research

Thus , the oxygen requirement to the respiratory muscles increases which results in decrease in use of oxygen by locomotor muscles. Resulting to this lack of oxygen, respiratoy muscles become fatigue. Morever, post exercise oxygen consumption and energy expenditure is more after high intensity exercise (Doucet, Imbeault, Alméras & Tremblay, 1999)
The purpose of conducting a lab is to measure the metabolic and energy expenditure with cycle ergometry. For any activities taking longer time than few minutes, main source of energy is through aerobic metabolism, as we do not store more amount of o2 in body, we must deliver o2 to tissue when it is needed during prolonged exercise. Therefore, we have to measure the volume of oxygen uptake (Vo2) and volume of carbon dioxide (Vco2) which produced by metabolism of sources of energy through indirect
