Abstract

People practicing high-intensity interval exercise (HIIE) fasted during the morning hours under a lack of sleep. Such a habit may jeopardize the health benefits related to HIIE and adequate sleep. Fifteen habitually good sleeper males (age 31.1 ± 5.3 SD year) completed on a treadmill two isocaloric (500 kcal) HIIE sessions (3:2 min work:rest) averaged at 70% VO2reserve after 9–9.5 h of reference sleep exercise (RSE) and after 3–3.5 h of acute-partial sleep deprivation exercise (SSE). Diet and sleep patterns were controlled both 1 week prior and 2 days leading up to RSE and SSE. HIIE related performance and substrate utilization data were obtained from the continuous analysis of respiratory gases. Data were analyzed using repeated measures ANOVA with the baseline maximum oxygen uptake (VO2max) and body fat percentage (BF%) as covariates at p < 0.05. No difference was observed in VO2max, time to complete the HIIE, VE, RER, CHO%, and FAT% utilization during the experimental conditions. Whether attaining an adequate amount of sleep or not, the fasted HIIE performance and metabolism were not affected. We propose to practice the fasted HIIE under adequate sleep to receive the pleiotropic beneficial effects of sleep to the human body.

Highlights

We hypothesized that the high-intensity interval exercise (HIIE) performance in the sleep deprived condition will be impaired, but results presented that the HIIE performance was not influenced by acutepartial sleep deprivation, even though a trend for a marginal decrease emerged
CHO% and less FAT% during the HIIE, but on the contrary, results showed that partial sleep deprived participants utilized more FAT% and less CHO% compared to the reference sleep and HIIE
Our findings suggest that acute-partial sleep deprivation has no impact on the HIIE

Summary

Introduction

Sleep research is commonly focused on acute-total and chronic-partial deprivation [1,2]with sleep related parameters to be either self-assessed (e.g., Pittsburgh Sleep QualityIndex–PSQI) [3,4,5,6,7,8,9,10] and/or objectively assessed with a sophisticated apparatus (e.g., sleep monitors, polysomnography, actigraphy) [4,5,6,9,10,11,12]. Sleep research is commonly focused on acute-total and chronic-partial deprivation [1,2]. Few studies have examined the acutepartial sleep deprivation with respect to the exercise performance, with most of them focusing on anaerobic performance (e.g., Wingate). Partial sleep deprivation at the end of the night decreases anaerobic performance compared to the deprived condition at the beginning of the night among Judokas [16]. Even fewer studies have focused on acute-partial sleep deprivation on aerobic performance, yielding contradictory findings. Antunes et al reported that sleep quality and duration assessed by PSQI are associated with the maximal incremental cycle ergometer performance and appears to be fitness independent.
