Altitude tents have become increasingly popular among speed skaters as a way to simulate high-altitude conditions and boost performance. Marcel Bosker, a four-time world champion, utilizes an altitude tent in his home to replicate mountain-like environments, a practice now common among major skating teams.

The primary benefit of altitude tents is to increase the production of red blood cells, enhancing oxygen delivery to muscles. By reducing the amount of oxygen in the air within the tent, the body compensates by producing more red blood cells, similar to the effects of training at high altitudes. This increased oxygen-carrying capacity can provide a competitive edge in endurance sports like speed skating.

However, coaches and athletes acknowledge that the effects of altitude tents vary among individuals. While some skaters experience significant improvements in fitness, others see little to no benefit, or even negative consequences such as disrupted sleep. This variability necessitates a customized approach, with coaches closely monitoring each athlete’s response to altitude tent training.

Despite the benefits, altitude tents have limitations compared to actual altitude training camps. The air composition in the tent differs from natural mountain air, potentially affecting the body’s response. Additionally, some coaches believe that the effects of altitude tents may be shorter-lived than those of traditional altitude training.

Coaches are often secretive about their specific altitude tent protocols, including the duration, frequency, and simulated altitude levels. This secrecy stems from the competitive nature of speed skating, where even small advantages can make a difference. However, the use of altitude tents is now widespread in the sport, with many teams renting the equipment for their athletes.

Altitude tents are not considered a magic bullet for success, but rather one tool among many in a comprehensive training program. Coaches emphasize the importance of balancing altitude training with other factors, such as muscle strength and technique. While altitude tents offer a convenient way to simulate high-altitude conditions, actual altitude training camps remain a valuable component of many skaters’ training regimens.
