Official title

Time at VO2max During High-Intensity Interval Training Manipulating Work and Rest

Overview

The project titled "Time at VO2max During High-Intensity Interval Training Manipulating Work and Rest" aims to investigate how different high-intensity interval training (HIIT) protocols influence the time athletes spend at or above 90% of their VO2max. By adjusting the work-to-rest ratios in the HIIT formats, the study seeks to determine which configurations maximize the time spent in this high-intensity zone, contributing to more effective endurance training strategies. The findings could help optimize training protocols for athletes targeting improvements in aerobic capacity and performance.

Interventions

  • Procedure Short Intervals HIIT
    Participants will undergo different high-intensity interval training (HIIT) protocols, which involve repeated bouts of exercise at an intensity above 90% of VO2max, followed by recovery periods. The work and rest durations will vary across the protocols to assess the impact on the total time spent at or above 90% of VO2max.
  • Procedure Long intervals HIIT
    Participants will undergo different high-intensity interval training (HIIT) protocols, which involve repeated bouts of exercise at an intensity above 90% of VO2max, followed by recovery periods. The work and rest durations will vary across the protocols to assess the impact on the total time spent at or above 90% of VO2max.

Primary outcome measures

  • time above 90% vo2max [Time frame: Duration of the HIIT (up to 20 minute)]
