Quick Answer
High Elevation Training is a well-documented approach to enhance endurance in athletes. Studies show that spending a short period at high altitude, typically between 2,000 to 3,000 meters, can lead to significant increases in red blood cell production, aerobic capacity, and exercise performance. This effect is most pronounced when the altitude exposure is brief but intense.
Benefits of High Elevation Training
High Elevation Training (HET) involves acclimatizing to lower oxygen levels at high altitude to stimulate physiological adaptations that enhance endurance performance. This approach is particularly effective for athletes competing in events at high elevations, such as the Tour de France or cross-country skiing. By adapting to the lower oxygen environment, athletes can increase their red blood cell count, improve oxygen delivery to muscles, and enhance aerobic capacity. For example, research has shown that a 10-day exposure to 2,400 meters can increase red blood cell production by 3-5%, leading to a 3-5% increase in aerobic capacity.
Practical Application of High Elevation Training
To implement HET effectively, athletes should aim to ascend to high altitude quickly, ideally within 24-48 hours. This rapid ascent triggers the body’s natural response to hypoxia, stimulating the production of erythropoietin (EPO) and subsequent red blood cell production. During the initial 7-10 days at high altitude, athletes should focus on low-intensity exercise to minimize the risk of altitude sickness while allowing their bodies to adapt. After this initial period, athletes can gradually increase their exercise intensity to simulate the demands of competition. Research has shown that a 2-4 week HET program can result in significant improvements in endurance performance, with studies demonstrating improvements in time to exhaustion by 5-15%.
