Yogic practices and physical activity increases blood flow in subjects and improve the micro circulation there was an increased peripheral blood flow, which brings greater amount of glucose to the sight of utilization. Such increased utilization glucose may bring about desirable decreasing blood sugar. The yogic practice group and physical activity group leads to hyper glycaemia, excess of sugar in gland due to glycogenolysis. But physical training leads to hypoxemia the practice of taking glucose during exercise is aimed more at prevention hypo glycaemia than in energy for the exercise.
