Time at VO2max During High-Intensity Interval Training

October 10, 2024 updated by: Filipe Silvano Pinto Maia, University of Maia

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

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: short intervals
This group will perform the hiit by doing short intervals
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.
