  1. Levels of fatigue (FIQ and MFIGF) at baseline (0 weeks), during training (15 weeks) and after training (30 weeks). Lean patients had BMI 18.5 to 24.9; overweight patients had BMI 25.0 to 29.9. Obese patients had BMI ≥30.0. Median values and interquartile range are indicated. aMann-Whitney U-test. n, number; BMI, body mass index; FIQ, Fibromyalgia Impact Questionnaire; MFIGF, Multidimensional Fatigue Inventory subscale of General Fatigue.
