The decline from the pre-training FEV1% to the posttraining FEV1% was calculated in each training session. The calculated declines of FEV1% were compared throughout the 12-week program using the one way ANOVA test followed by multiple comparisons POST-HOC Benferroni method. There was a significant difference between all sessions regarding the calculated declines of FEV1% being decreasing sequentially from the first to the last training week (F=31.424,p= 0.000). The change of the calculated declines of FEV1% over the 12-week program time is presented in Fig. 3.
