Summary

Hypobaric hypoxia significantly reduces peak oxygen uptake (VO2) in swimmers during both front crawl and arm strokes. The percentage decrease in peak VO2 was similar for both swimming styles, suggesting a central limitation.

Area of Science:

  • Sports Science
  • Exercise Physiology
  • Environmental Physiology

Background:

  • Swimming performance is influenced by oxygen uptake, especially under hypoxic conditions.
  • Understanding the limiting factors in swimming is crucial for optimizing training and performance.

Purpose of the Study:

  • To investigate the limiting factor for swimming performance under hypobaric hypoxic conditions.
  • To measure peak oxygen uptake (peak VO2) during front crawl and arm stroke swimming.
  • To compare the effects of hypobaric hypoxia on peak VO2 in different swimming strokes.

Main Methods:

  • Seven trained swimmers performed front crawl and arm stroke exercises in a hypobaric hypoxic chamber.
  • Water flow rate was progressively increased until exhaustion.

  • Peak oxygen uptake (peak VO2) and heart rate were measured using an automatic analyzer.

    • Main Results:

    • Peak VO2 values were significantly lower under hypobaric hypoxic conditions compared to normal conditions for both swimming strokes.
    • Peak VO2 during arm stroke was significantly lower than during front crawl under both normal and hypoxic conditions.
    • The percentage decrease in peak VO2 under hypoxia was similar for front crawl (12.0%) and arm stroke (9.8%).

    Conclusions:

    • Hypobaric hypoxia limits swimming performance by reducing peak oxygen uptake.
    • The similar reduction in peak VO2 for front crawl and arm stroke suggests a central physiological limitation.
    • These findings align with previous studies on centrally limited exercise under hypoxia, such as running and cycling.
