p-values of Linear Mixed-Effects Models analyses (significant values in bold)* significant within-group change from Pre to Post
anot normally distributed and log transformed for the analyses. For easier interpretation, non-transformed data means were reported for all variables. F
0 = theoretical maximal isometric force; V
0 = maximal velocity; S
FV/F
0 = the slope of the force-velocity relationship relative to F
0; P
max = maximal muscle power
