Abbreviations: BMI: body mass index; 1RM: 1-repetition maximum; strength score: sum of all three strength measures, WC: waist circumference. Significance was calculated using Wilcoxon signed-rank test. P-values with a superscript b indicate between-group analysis, and w indicates within-group analysis. Median values are presented with 25th and 75th percentile in parentheses, and median change scores are presented with the accompanied 95% confidence intervals.
Significant P values (P<0.05) are bolded.
