Increased air temperature during repeated-sprint training in hypoxia amplifies muscle oxygenation flux without decreasing cycling performance

Abstract

Introduction: Training under environmental stress is a popular approach to enhance athlete adaptation. Although the advantages repeated-sprint training in hypoxia (RSH) and heat exposure are well established, the benefits of a session combining these two stimuli are not yet understood. As such, the purpose of this study was to investigate the acute performance and physiological responses, with specific reference to muscle oxygenation, to ambient air temperature manipulation during RSH.
