NCT06636916

Brief Summary

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

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.
