Figure 1. Mean changes of HR, O2-pulse and EqO2 at the submaximal workload of 150 W for the hypoxic and normoxic training group. Data are presented as percentage (%) change. Sample size : NG= 4; HG= 6. HG, hypoxic training group; HR, heart rate; NG, normoxic training group; EqO2, ventilatory equivalent for oxygen. *significant within-group changes (p≤0.05). #significant between-group changes (p≤0.05)
