Data analysis
The SPSS (version 23.0) is used for data management and statistical analysis. The kolmogorov-Smirnov test is used for normality test. The normality data are expressed as mean ± standard deviation, and the skewness data are expressed as median and quartile spacing. An intention-to-treat analysis will be used to assign participants whether or not they complete the intervention. Lost result data will be processed using a mixed-mode approach. Each protocol is then analyzed, including only subjects who completed all outcome measures and followed the intervention protocol. One-way analysis of variance (ANOVA) or nonparametric tests wil be used to compare baseline differences between groups. The effects of training are evaluated using a 22 ANOVA (group × time). Using either a paired T-test or a nonparametric test, differences in each group of variables over time (from baseline to three months) will be evaluated. To detect differences between categorical variables, the Chi-square test will be applied. P values less than 0.05 are considered significant.
