Abstract
High Intensity Interval Training (HIIT) has become extremely popular in recent years, however, current HIIT prescriptions lack guidelines regarding interval intensities and associated margins. The purpose of this study is to investigate Run Time to Exhaustion (Te) and provide insight regarding HIIT intensities for future aerobic exercise programming. Ten healthy adult male recreational runners (Age=22.9 ± 2.5 yr., Ht=1.72 ± 0.1m, BM=74.1 ± 7.4 kg) measured maximal oxygen consumption (VO2max) (52.4 ± 6.1ml/kg/min) with a graded exercise test (GXT). Running speed was determined using ACSM running equation for exercise metabolism. Protocols 1-3 were HIIT running sessions, and Protocol 4 was a continuous running trial, all of the same average intensity (80% VO2max). All HIIT trials implemented aerobic style bout durations of 2 minutes each, with a 1:1 work to active rest/recovery ratio. A repeated measures ANOVA determined that mean Te differed statistically between the 4 protocols. Protocol 1 elicited a significant reduction in mean Te when compared to all other conditions. Based on the findings of this study, recreational runners can monitor variables and/or prescribe intensities to maximize economy and efficacy of aerobic HIIT program implementation.
