Abstract:
Today there is a growing emphasis on looking good, feeling good and living longer. Increasingly scientific evidence tells us that one of the keys to achieving these ideals is fitness and exercises. Aerobic exercise is physical exercise of relatively low intensity that depends primarily on the aerobic energy-generating process. Major muscles in a rested, untrained human typically contain enough energy for about 2 hours of vigorous exercise. Exhaustion of glycogen is a major cause of what marathon runners' call "hitting the wall". Training, lower intensity levels and carbohydrate loading may allow postponing the onset exhaustion beyond 4 hours. there was no significant difference in Vital capacity, Blood pressure and Respiratory rate as the calculated‘t’ viz, 0.15, 0.335, 1.51 and 1.35 respectively were much below then the tabulated value of 2.021 required for‘t’ ratio to be significant at 0.05 level of significance with the degree of freedom 38 Aerobic exercise and fitness can be contrasted with anaerobic exercise, of which strength training and short-distance running are the most salient examples. Some sports are thus inherently "aerobic", while other aerobic exercises, such as fartlek training or aerobic dance classes, are designed specifically to improve aerobic capacity and fitness.
