Cover Story (view full-size image): Performing a physical warm-up has numerous physiological and performance benefits. We investigated whether performing warm-up with blood-flow restriction (WFR), which is known to potentiate endothelial and metabolic functions, induces ergogenic changes in muscle oxygenation and performance during twelve 20 m sprints in trained team-sport athletes. Compared with regular warm-up, WFR increased blood volume and muscle oxygenation during some sprint and recovery periods. Unfortunately, WFR did not alter best sprint time nor total time but tended to reduce percent decrement. Results indicate that WFR positively alters skeletal muscle haemodynamics during short sprints. These physiological changes could benefit players during longer activities. View this paper.
