High Intensity Interval Training (HIIT) has become popular in recent years, but a lack of guidelines for interval intensities and margins compromise exercise prescription. The purpose of this study was to investigate the effects of 3 HIIT sessions and 1 continuous running session of the same average intensity (80% VO2max) on total Run Time to Exhaustion (TE). Ten adult male recreational runners (Age=22.9 ± 2.5 yr, Height=1.72 ± 0.1m, Body Mass=74.1 ± 7.4 kg) completed running sessions, with HIIT trials featuring 2 minute bouts and a 1:1 ratio of work to active recovery. A repeated measures ANOVA revealed mean TE differed significantly between conditions (F (3, 27) = 23.4071, p < 0.05).
