Cerebral and Muscle Oxygenation during Repeated Shuttle Run Sprints with Hypoventilation

Ten highly-trained Jiu-Jitsu fighters performed 2 repeated-sprint sessions, each including 2 sets of 8 x $∼$6 s back-and-forth running sprints on a tatami. One session was carried out with normal breathing (RSN) and the other with voluntary …

Physiological adaptations to repeated sprint training in hypoxia induced by voluntary hypoventilation at low lung volume

Purpose: This study investigated the effects of repeated-sprint (RS) training in hypoxia induced by voluntary hypoventilation at low lung volume (RSH-VHL) on physiological adaptations, RS ability (RSA) and anaerobic performance. Methods: Over a …

The effect of severe and moderate hypoxia on exercise at a fixed level of perceived exertion

Purpose: The purpose of this study was to determine the primary cues regulating perceived effort and exercise performance using a fixed-RPE protocol in severe and moderate hypoxia. Methods: Eight male participants (26 ± 6 years, 76.3 ± 8.6 kg, 178.5 …

Acute effects of repeated cycling sprints in hypoxia induced by voluntary hypoventilation

Purpose: This study aimed to investigate the acute responses to repeated-sprint exercise (RSE) in hypoxia induced by voluntary hypoventilation at low lung volume (VHL). Methods: Nine well-trained subjects performed two sets of eight 6-s sprints on a …
