What Are The Effects Of Altitude Training On Athletic Performance And Acclimatization?

Introduction

Altitude training, which involves training at high altitudes, is a common practice among athletes aiming to enhance their performance. The primary rationale behind this practice is the physiological adaptations that occur due to reduced oxygen availability at higher altitudes, which can potentially improve performance upon return to sea level. This synthesis examines the effects of altitude training on athletic performance and acclimatization based on multiple research studies.

Key Insights

Living High-Training Low Strategy:
- Living at moderate altitude (around 2,500 m) while training at lower altitudes (around 1,250 m) improves sea-level performance in trained runners by increasing VO2 max and red cell mass volume .
- This strategy is effective for both elite and sub-elite athletes, leading to significant improvements in endurance performance .
Hemoglobin and Oxygen Transport:
- Acclimatization to altitude increases hemoglobin concentration, which is a key adaptation that enhances aerobic power and performance upon return to sea level .
- Increased erythropoiesis, indicated by elevated erythropoietin and soluble transferrin receptor levels, supports improved oxygen transport capacity.
Performance at Altitude:
- Initial exposure to high altitude can impair aerobic performance due to reduced oxygen uptake, but acclimatization over time can mitigate these effects .
- Short-term acclimatization (e.g., 45 hours) can partially recover aerobic performance losses, while anaerobic performance remains largely unaffected.
Optimal Acclimatization Altitude:
- For athletes competing at moderate altitudes (around 1,780 m), living at the competition altitude is more beneficial than living at higher altitudes, which may initially worsen performance and require longer acclimatization periods.
Risks and Considerations:
- Athletes are at risk of developing acute high altitude illness (AHAI) due to rapid ascent and vigorous exertion. Proper acclimatization is crucial to prevent such conditions.
- Training at high altitudes can decrease VO2 max and reduce training workloads, necessitating careful planning of training programs to balance acclimatization benefits with performance maintenance.

Conclusion

Altitude training, particularly the "living high-training low" strategy, is effective in enhancing sea-level performance by improving VO2 max and red cell mass volume. Acclimatization increases hemoglobin concentration and supports better oxygen transport, which are crucial for improved aerobic performance. While initial exposure to high altitude can impair performance, adequate acclimatization can mitigate these effects. Athletes should carefully plan their altitude training and acclimatization strategies to optimize performance and minimize risks associated with high altitude exposure.
