Repeated-sprint performance and vastus lateralis oxygenation: Effect of limited O2 availability

This study examined the influence of muscle deoxygenation and reoxygenation on repeated-sprint performance via manipulation of O2 delivery. Fourteen team-sport players performed 10 10-s sprints (30-s recovery) under normoxic (NM: FIO2 0.21) and acute …

Short intermittent hypoxic exposures augment ventilation but do not alter regional cerebral and muscle oxygenation during hypoxic exercise

This study investigated the effects of four exposures to normobaric hypoxia (SIH group; FIO2=0.120, N= 10) or placebo-control normoxia (Control group; FI O2=0.209, N= 9) on cardio-respiratory responses to hypoxic exercise. Before and after the …
