Daily variability in exercise ventilation (VE) is small in runners. Stable VE measures can be obtained by averaging results from just two testing sessions, even if they are not consecutive.

Area of Science:

  • Exercise Physiology
  • Sports Science
  • Human Physiology

Background:

  • Understanding daily variability in physiological measures is crucial for accurate research.
  • Exercise ventilation (VE) is a key indicator of cardiorespiratory function during physical activity.
  • Previous research has not fully established the reliability of daily VE measurements in trained athletes.

Purpose of the Study:

  • To quantify the daily variability of exercise ventilation (VE) in trained runners.
  • To determine the minimum number of testing sessions needed for stable VE measurements.
  • To assess the impact of training and racing on VE consistency.

Main Methods:

  • Four male and four female distance runners underwent daily treadmill testing for five weeks.

  • Subjects performed three 6-minute submaximal runs at standardized speeds daily.
  • Ventilation (VE) was measured during the final two minutes of each run.

    • Main Results:

    • The mean coefficient of variation for VE across different speeds was 4.33%.
    • 97% of the variation in mean VE was explained by data from just two testing days (consecutive or non-consecutive).
    • 98% of VE variation was accounted for within five consecutive testing days.

    Conclusions:

    • Intraindividual differences in exercise VE are minimal in trained runners when controlling for circadian rhythms and treadmill exposure.
    • Stable VE values can be reliably obtained by averaging measurements from two testing sessions.
    • This finding supports efficient and reliable protocols for assessing exercise ventilation in athletic populations.
