Subject group (N = 38) performances in isokinetic concentric tests of lower body and trunk muscle power and postural stability.

Isokinetic tests of absolute (W) and relative (W·kg−1) muscle power, maximal and endurance. The statistical method (SM) was parametric (P) or non-parametric (NP) (see Methods section). Parametric tests are presented as mean ± standard deviation (min-max). Non-parametric tests are presented as median ± Interquartile range (min-max). Groups marked with different symbols in rows (*, †) are significantly (p<0.01) different (* significantly different from †).
