The values are presented as the means ± SD. STRE: strengthening exercise, FLEX: Flexibility exercise. FIQ: Fibromyalgia Impact Questionnaire. SF-36: Short-Form healthy Survey. VO2 max: maximal oxygen uptake. Wilcoxon Test: intra-group comparison. ANOVA: inter-group comparison, analysis of variance for repeated measures, p value: inter-group difference, *p≤0.05. Pos hoc Bonferroni’s test. Handgrip and Wells’ Bench data refer to N = 18 in the STRE group and N = 20 in the FLEX group.
