ANOVA outcome.
Fig 1.
Means of subjects’ strength performance measures during pre and post training testing.
A: maximal voluntary isometric force of the left leg (MIF-ULL); B: maximal voluntary isometric force of the right leg (MIF-ULR); C: maximal voluntary isometric force of both legs (MIF-BL). HRT = bilateral heavy-resistance strength training group, BAL = predominately unilateral balance training group, CON = old adults control group, YA = young adults control group. Error bars represent standard deviation (SD); brackets show Cohen’s d.
Fig 2.
Means of subjects’ bilateral deficit (BLD) in maximum voluntary isometric force during pre and post training testing.
HRT = bilateral heavy-resistance strength training group, BAL = predominately unilateral balance training group, CON = old adults control group, YA = young adults control group. Error bars represent standard deviation (SD). Brackets show Cohen’s d. The dashed line indicates the BLD of YA.
Fig 3.
Association between the training-induced changes in maximal voluntary contraction for both legs (∆MIF-BL) and the change in bilateral deficit (∆BLD) for the bilateral heavy-resistance training group (HRT) and the predominately unilateral balance training group (BAL).
Pearson’s correlation coefficients (r) are displayed separately for HRT and BAL.
