Figure 3. Changes in exercise performance (maximal oxygen consumption; VO2max and 400-m time trial) induced by training in normoxic training (NT) and hypoxic training (HT) groups. a. VO2max and b. 400-m time trial. Bars indicate mean ± SD. *: Significant (p < 0.05) interaction or main effect. †: Significant (p < 0.05) difference between the before training and after training values in each group.
