The changes on the hrv after a wıngate anaerobıc
Exercises at altitude make more rapid and greater physiological changes than those at sea level. This is because altitude hypoxia leads to exercise-induced physiological changes such as total blood volume, hemoglobin, number of red blood cell, mitochondrial concentration and muscle enzyme activity changes(1). Sincethe Mexico City Olympic Games were heldin 1968, the high altitude training (HAT) methods have had a substantial place in the area of training sciences to enhance the performance of athletes(2). Researchers tried live high-train highprocedure to gain the positive conse-quences of altitude training extensively(2, 3, 4, 5).
Nevertheless, due to the fact that to bring ath-letes to high altitude, and keep them there at least a couple of weeks(6) take a long time and cost too much, new approaches have been found. To provide live high-train low/high or live low-train high (also known as intermittent hypoxic training) environ-ments at the sea level, some special altitude cham-bers and/or devices in laboratories have been uti-lized(7, 8, 9).
