CG, control group; LG, Liuzijue exercise group; LEG, Liuzijue exercise combined with elastic-band resistance exercise group; FEV 1, forced expiratory volume in 1 second; FVC, forced volume capacity; MMEF, maximal midexpiratory flow; 6MWD, 6-min walking distend; 6MWD%pred, 6-min walking distance as a percentage of the predicted value; 30s SST, 30s sit-to-stand test.
Notes: data was expressed as mean ± SD. The paired sample t-test was used for comparisons within groups, the one-way analysis of variance (ANOVA) was used for comparisons among groups, and post hoc multiple comparisons were performed using Bonferroni test. The significance level was set at P<0.05. None of significant difference has been found between the two training groups.
∗p < 0.05, comparisons are significant within groups. ∗∗p < 0.01, comparisons are significant within groups.
aP values for the comparison of outcome variables from baseline to 6-month among three groups.
bP values for the comparison of P values between CG and LG.
cP values for the comparison of P values between CG and LEG.
