Abstract

Purpose: Recent studies have demonstrated that modifying the ‘classic’ 6x30-s ‘all-out’ sprint interval training (SIT) protocol by incorporating either shorter sprints (6x10-s or 15-s sprints) or fewer sprints (e.g. 2x20-s sprints; reduced-exertion high-intensity interval training (REHIT)) does not attenuate the training-induced improvements in maximal aerobic capacity (VO2max). The aim of the present study was to determine whether reducing the sprint duration in the REHIT protocol from 20 s to 10 s per sprint influences acute affective responses and the change in VO2max following training. Methods: Thirty-six sedentary or recreationally active participants (17 women; mean ± SD age: 22±3 y, BMI: 24.5±4.6 kg·m-2, VO2max: 37±8 mL·kg-1·min-136 ) were randomised to a group performing a ‘standard’ REHIT protocol involving 2x20-s sprints or a group who performed 2x10-s sprints. VO2max was determined before and after 6 weeks of 3 weekly training sessions. Acute affective responses and perceived exertion were assessed during training.Results: Greater increases in VO2max were observed for the group performing 20-s sprints(2.77±0.75 to 3.04±0.75 L·min-1 ; +10%) compared to the group performing 10-s sprints (2.58±0.57 vs. 2.67±3.04 L·min-1 ; +4%; group × time interaction effect: p
