Skiing is a sport to cultivate endurance. In competitive competitions, because the distance of exercise is relatively long (teenagers 1- 10 km, adults 10-50 km), continuous exercise in the snow and ice is very beneficial to human endurance training. When skiing, the human body exercises under aerobic metabolism, which promotes the growth and development of teenagers and is also beneficial to the physical quality of adults. The process of aerobic metabolism is simply that when the human body is exercising, it inhales the oxygen needed for the metabolic process from the atmosphere.
