happoharjoittelu

Happoharjoittelu, also known as hypoxic training, is a method of exercise that involves training in low-oxygen environments. This can be achieved in several ways, including exercising at high altitudes or using specialized equipment like altitude tents or rooms that simulate lower oxygen levels. The primary goal of happoharjoittelu is to stimulate physiological adaptations that can enhance athletic performance, particularly in endurance sports.

The theory behind this training method is that reduced oxygen availability triggers the body to produce more red blood cells. Red blood cells are responsible for carrying oxygen to the muscles, so an increase in their number can lead to improved oxygen transport capacity. This, in turn, can enhance aerobic capacity and endurance, allowing athletes to perform at higher intensities for longer periods. Other proposed benefits include improved recovery, increased motivation, and enhanced fat metabolism.

Happoharjoittelu can be implemented using different protocols. "Live high, train high" involves living and training at high altitude. "Live high, train low" means sleeping at altitude but training at sea level, aiming to benefit from the red blood cell adaptations while maintaining high-intensity training. Intermittent hypoxic exposure involves short periods of breathing low-oxygen air interspersed with normal air. While popular among some athletes and coaches, the scientific evidence supporting the benefits of happoharjoittelu is still a subject of ongoing research and debate. Individual responses can vary, and potential risks or drawbacks should also be considered.
