Influence of recovery duration during 6-s sprint interval exercise on time spent at high rates of oxygen uptake.

ABSTRACT:

Background/objective

This study examined whether time spent at high rates of oxygen consumption (VO₂) during 6-s sprint interval exercises (SIE) is a function of recovery interval duration.

Methods

In a randomised crossover study, thirteen male endurance runners performed 40 × 6-s all-out sprints interspersed with 15-s, 30-s and 60-s passive recovery intervals (SIE₁₅, SIE₃₀, and SIE₆₀ trials respectively), and a work duration-matched Wingate-SIE (8 × 30-s all-out sprints with 4-min passive recovery, SIE_Win trial). The accumulated exercise time at ≥ 80%, 85%, 90%, 95% and 100% of VO_2max, and maximum heart rate (HR_max) in the four trials were compared.

Results

During the 6-s SIEs, accumulated t
