Elite speed skaters are increasingly using altitude tents to simulate high-altitude conditions and boost their performance. These tents, which create an environment with reduced oxygen levels, mimic the effects of training at high altitudes, prompting the body to produce more red blood cells, which enhances oxygen delivery to muscles.

Marcel Bosker, a four-time world champion, uses an altitude tent at home, highlighting the growing trend among skaters. While he admits the process is “terribly boring,” he recognizes the benefits for his conditioning. Many major skating teams now utilize altitude tents, a practice that was once limited to a few individuals or teams.

However, the use of altitude tents is shrouded in some secrecy, with coaches being cautious about sharing information. The effects of altitude training vary from person to person, requiring customized approaches. Some athletes experience significant improvements in their condition, while others see little or no effect. Some even experience negative effects like disrupted sleep.

Altitude tents work by filtering oxygen from the air, forcing the body to compensate for the reduced oxygen levels by producing more red blood cells. This is similar to the body’s response to altitude training camps, which are typically conducted at elevations of 1,800 meters or higher. Upon returning to sea level, the increased red blood cell count can temporarily improve oxygen absorption, which is beneficial for endurance sports like skating.

While altitude tents offer a convenient way to simulate altitude training, they have limitations. The air mixture in the tent is different from that at real altitude, with a higher proportion of other gases like nitrogen and carbon dioxide. Some coaches believe the effects of altitude tents may not last as long as those of real altitude training. Furthermore, the reduction of muscle mass and coordination may be impacted.

Coaches emphasize the importance of careful monitoring and individualization when using altitude tents. Some skaters may not respond well to altitude simulation, and the intensity of training sessions must be adjusted to avoid overexertion. The balance between conditioning and muscle strength needs to be managed, especially for explosive skaters who may be more susceptible to muscle loss at altitude.
