The Impact of Altitude Training on Performance

impact of altitude training

Altitude training has become a buzzword in the world of sports and fitness, known for its potential to significantly boost athletic performance. This training method involves exercising in, living in, or otherwise being exposed to conditions of higher altitude where oxygen levels are lower. In this blog post, we’ll explore the impact of altitude training on athletic performance and why many athletes incorporate it into their training regimens.

Understanding Altitude Training

At higher altitudes, the air is thinner, meaning there’s less oxygen available. When athletes train under these conditions, their bodies are forced to adapt to the decreased oxygen levels. These adaptations can lead to significant improvements in performance, especially when athletes return to sea level to compete.

Physiological Adaptations to Altitude Training

  • Increased Red Blood Cell Production: The body responds to lower oxygen availability by producing more red blood cells, which transport oxygen to the muscles.
  • Enhanced Aerobic Capacity: Over time, altitude training can lead to improved VO
  • 2 max (maximum oxygen uptake), which is a key indicator of aerobic endurance.
  • 3. Improved Oxygen Efficiency: The body becomes more efficient at utilizing oxygen, which can enhance endurance performance.
  • Muscle Adaptations: There can be changes in muscle composition and function, favoring more efficient energy use.

Types of Altitude Training

  • Live High, Train High (LHTH): Athletes live and train at high altitude. This method provides constant exposure to low oxygen but can impact training intensity due to the reduced oxygen.
  • Live High, Train Low (LHTL): Athletes live at high altitude but train at lower altitudes. This method is popular for maintaining training intensity while still gaining altitude adaptation benefits.
  • Intermittent Hypoxic Training (IHT): Athletes train in hypoxic conditions for short periods and then return to sea level. This can be achieved through natural or artificial means, like hypoxic chambers.

Benefits of Altitude Training

  • Endurance Enhancement: The primary benefit is improved endurance, as the body becomes more efficient at oxygen utilization.
  • Performance Boost at Sea Level: Many athletes find that their performance at sea level improves after a stint of altitude training.
  • Mental Toughness: Training in challenging conditions can also enhance mental strength and resilience.

Challenges and Risks of Altitude Training

  • Risk of Altitude Sickness: Symptoms include headaches, nausea, and sleep disturbances, which can hinder training.
  • Individual Response Variability: Athletes may respond differently to altitude training, with some experiencing greater benefits than others.
  • Reduced Training Intensity: The lack of oxygen can limit how hard athletes can train, potentially impacting high-intensity training sessions.

Scientific Evidence on Altitude Training

Research shows mixed results. Some studies have found significant improvements in performance at sea level following altitude training, while others have seen minimal benefits. The effectiveness can depend on factors like the duration of the training, the altitude, and the individual athlete’s response.

Best Practices for Altitude Training

  • Gradual Acclimatization: It’s important to acclimatize to high altitudes gradually to reduce the risk of altitude sickness. This involves slowly increasing altitude exposure over several days or weeks.
  • Monitoring Health: Regular monitoring of health indicators like blood oxygen levels and heart rate is crucial.
  • Hydration and Nutrition: Staying well-hydrated and ensuring adequate nutrition, especially iron intake, is vital as dehydration and nutrient deficiencies can exacerbate the challenges of high-altitude conditions.
  • Personalized Approach: Tailoring the altitude training program to the individual athlete’s needs, fitness level, and response to altitude is important.
  • Recovery Time: Allowing adequate time for recovery after training sessions and between altitude training cycles is essential.

Altitude Training for Different Sports

  • Endurance Sports: Runners, cyclists, and swimmers often benefit most from altitude training, as their sports are heavily dependent on aerobic capacity.
  • Team Sports: Athletes in sports like soccer or basketball may use altitude training to enhance their overall endurance and recovery time during games.
  • Strength and Power Sports: While less common, athletes in sports focused on strength and power, such as weightlifting, may also use altitude training, particularly for the physiological and mental toughness benefits.

Incorporating Altitude Training into a Training Program

A well-planned altitude training program should be integrated into the overall training plan strategically. This might involve specific cycles or phases where altitude training is emphasized, particularly leading up to major competitions.

Use of Artificial Altitude Environments

With advancements in technology, artificial altitude environments, such as hypoxic chambers and tents, have become more accessible. These allow athletes to simulate high-altitude conditions without needing to travel to high-altitude locations. While beneficial, they should be used under professional guidance to ensure safety and effectiveness.

Recovery Strategies Post-Altitude Training

After completing an altitude training cycle, it’s important to focus on recovery strategies to help the body adjust back to sea-level conditions. This may include rest, hydration, nutrition, and gradual reintroduction to sea-level training intensities.

Research and Future Directions

Continued research into altitude training is shedding more light on its effectiveness, how athletes can maximize its benefits, and the mechanisms behind its impact on performance. Future developments may include more personalized approaches to altitude training and new technologies for simulating high-altitude conditions.


Altitude training presents a unique and effective way for athletes to enhance their performance, particularly in aerobic capacity and endurance. By understanding the physiological adaptations to high altitude, athletes and coaches can harness these benefits to gain a competitive edge. However, it’s crucial to approach altitude training with caution, considering the potential risks and ensuring a well-planned and individualized training program. As research in this area continues to evolve, altitude training will likely remain a valuable tool in the arsenal of athletes striving for peak performance.
