Abstract
  • The effects of a short-term (3-week) integrated body weight reduction (BWR) program on fatigue perception and on lower limb anaerobic power output were evaluated in 200 severely obese in-patients (40 males and 160 females, age: 18-83 yr, BMI: 35.0-65.3 kg/m2). Fatigue was assessed by a 7-point Likert-type scale questionnaire (Fatigue Severity Scale, FSS), while average lower limb power output (W) during a maximal effort was determined with a modification of the Margaria test for stair climbing. In both genders, total FSS score was influenced by both age and obesity level, resulting significantly (p < 0.001) lower in younger subjects (< 45 yr) than in older (> 45 yr) and in patients with lower BMI (< 40 kg/m2) than in those with a higher one (> 40 kg/m2). An opposite trend was observed in W. The 3-week BWR integrated program with moderate aerobic exercise and free standing and ground gymnastic routines induced a significant reduction in body weight (p < 0.001), in total FSS score (p < 0.001) and a significant increase in W, both in absolute terms (p < 0.05) and relative to body mass (p < 0.001). Total FSS score and absolute or relative power output were positively correlated both before and after the BWR program (p < 0.001, Wilcoxon rank test). It is concluded that: a) subjective fatigue perception, assessed by a FSS questionnaire, can be considered an indirect indicator of effective lower limb power output in severely obese patients and, b) in spite of a relatively small, although significant, decline of BMI, the full-time participation in a hospital-based, integrated BWR program with moderate exercise activity is associated with significant short-term improvements of both fatigue sensation and power output.
