3.4.1. FEV1%
15 studies [14,17-19,21-23,25,26,30-34,36,37] provided numerical
data for the FEV1, five comparisons against control were
performed (Fig. 4a). Compared with the conventional treatment, there was
no significant difference: endurance training [WMD=-0.05, 95% CI
(-4.75, 3.66)], endurance and strength training [WMD=1.00, 95% CI
(-8.80, 10.80)], endurance and respiratory training [WMD=0.35, 95%
CI (-7.32, 8.02)], endurance, resistance and respiratory training
[WMD=5.19, 95% CI (-2.38, 12.75)], respiratory and strength
training [WMD=-2.45, 95% CI (-8.38, 3.48)], endurance and
respiratory training [WMD=4.23, 95% CI (-2.68, 11.14)]. After
combined analysis, there was no statistical significance between
exercise PR and lung function FEV1 [WMD=0.59, 95% CI
(-2.0,3.19)] (Fig. 4b).
