Benefits of Training in the Heat
Training at high altitude was thought to benefit athletes as there is less oxygen in the air, which makes the body produce more red blood cells, which in turn creates increased oxygen capacity when the athlete returns to lower altitude levels. For most of us, this training method is unrealistic unless you have access to a plane to travel to high altitude facilities or have a hypobaric chamber. However, research in the Frontiers in Physiology suggests similar cardiac benefits
