Hypoxic ventilatory response is correlated with increased submaximal exercise ventilation after live high, train low
This study tested the hypothesis that live high, train low (LHTL) would increase submaximal exercise ventilation in normoxia, and the increase would be related to enhanced hypoxic ventilatory response (HVR). Thirty-three cyclists/triathletes were divided into three groups: 20 consecutive nights of hypoxia (LHTLc, n=12), 20 nights of intermittent hypoxia (4x5-night ‘blocks’ of hypoxia interspersed by two nights of normoxia, LHTLi,n=10), or control (CON,n=11). LHTLc and LHTLi slept 8–10 h per night in normo-baric hypoxia (2,650 m), and CON slept under ambient conditions (600 m).
