Data analysis
In order to assess whether the measurements of the outcome variables were normally distributed the Shapiro–Wilk test was used. This analysis revealed that all outcome measures (i.e. C7WD, SH, BSL, BSR, CSRL, CSRR, TUG, BADL, and BSES) in both the Exercise Group (EG) and the Control Group (CG) were not normally distributed. Non-parametric Multivariate Analysis of Variance (MANOVA) was therefore performed to investigate whether a significant interaction effect existed between group and time for the 8 week SSG training for the set of all outcome measurements and for the four categories of (1) Posture (C7WD and SH), (2) Flexibility (BSL, BSR, CSRL and CSRR), (3) Gait (TUG) and (4) Cognition (BADL and RSES). The particular analysis that was performed used the MANOVA.RM package of R software (R Core Team (2020). R: A language and environment for statistical computing.
