The effect of intermittent training in hypobaric hypoxia on sea-level exercise: a cross-over study in humans

摘要: The purpose of this study was to examine the effect intermittent training in a hypobaric chamber on physical exercise at sea level. Over 10 day period, 16 male triathletes trained for 2 h each day cycle ergometer placed chamber. Training intensity 60%–70% heart rate reserve. There were 8 subjects who simulated altitude 2,500 m, other A year later, cross-over took place. Baseline measurements made level, which included an incremental test until exhaustion and Wingate Anaerobic Test. Altogether, 12 subjects completed study. At 9 days after hypoxia, significant increases seen maximal power output ( $$ \dot W_{{\rm max}} $$ )(5.2%), anaerobic mean (4.1%), peak (3.8%). non-significant increase oxygen uptake (V˙O2max) 1.9% observed. no changes (2.1%), V˙O2max (2.0%), (0.2%) (0.2%). When comparing results two regimes, only variable that showed significantly larger as result altitude. And, although differences percentage change between protocols not significant, they substantial well power. indicate can improve energy supplying system, also, lesser extent, aerobic system. It be concluded overall predominantly improvements metabolism variance with previous our own group, where relative increased by 7%.
