Effects of 15 weeks of resistance exercise on pro-inflammatory cytokine levels in the vastus lateralis muscle of patients with fibromyalgia

Table 2 Overall pain intensity, pain intensity in exercising leg, and fatigue in 24 patients with fibromyalgia (FMS) and 27 healthy controls (CON) before and after 15 weeks of resistance exercise twice per week, as well as the P value for within-group comparison (Wilcoxon test)

		FMS		P value	CON		P value
		Before	After		Before	After
Pain	Overall (0–100)	53.5 (29.3)	50.0 (23.5)	*0.025*	0 (0)	0 (0)	0.723
	Leg (0–100)	52.8 (24.4)	42.8 (32.7)	0.153	0 (1.5)	0 (0)	0.751
Fatigue	Borg RPE	13.3 (2.7)	11.5 (4.0)	0.095	7.8 (2.8)	7.4 (3.0)	0.689

The figures represent the average of data sampled during microdialysis (140-220 min), which included 20 min of dynamic exercise. Data are presented as median (interquartile range)
All variables differed significantly between groups at both sessions (P < 0.001; Mann-Whitney U test)
Bold italic figures denote significant differences
