Castres I, et al. – In this pilot study, the authors intend was to assess the impact of a walking program of 10,000 steps per day and dietary counseling on health–related quality of life (HRQoL), resting energy expenditure (REE) and anthropometric parameters in obese subjects. This study concluded that Walking 10,000 steps per day in association with dietary counseling improved anthropometric data, REE, the physical domains of HRQoL and anxiety in obese adults.

Methods

  • In this study, 35 obese adults (26 women; age: 39.2 ± 13.4 years, body mass, BM: 104.1 ± 18.7 kg and body mass index, BMI: 38.3 ± 6.6 kg m–2) followed a walking program (instructions were provided so that the participants increase their walking distance by 1000 steps each week, until to perform at least 10,000 steps per day) and received qualitative dietary advice (cookbook presenting numerous recipes with low calories and dietary advices was provided) for 6 months.
  • Further to this, before and after the intervention, anthropometric (BM, BMI, waist and hip circumferences, fat mass: FM and lean body mass: LBM) and biological data (total cholesterol, high–density lipoprotein, low–density lipoprotein, triglyceride and glucose concentrations), REE and HRQoL (including eight dimensions and two summaries) were evaluated.

Results

  • Researchers found that after the intervention, BM (difference: 3.8 kg or 3.7 %), BMI (difference: 1.4 kg m–2 or 3.7 %), hip circumference (difference: 4.6 cm or 4.3 %), FM in kg (difference: 4.0 kg or 8.9 %) and FM in percentage of BM (difference: 1.6 kg or 6.1 %) were significantly decreased, whereas number of steps (difference: 7579 steps or 135 %), LBM in percentage of BM (difference: 2.6 kg or 4.5 %) and REE (difference: 78 kcal d–1 or 4.8 %) were significantly expanded (p < 0.05).
  • Two HRQoL subdimension scores (physical functioning and physical component summary; increase by 15.3 and 4.6, respectively, p < 0.05) and anxiety (reduction by 1.2, p < 0.05) were also significantly improved.
  • On the other hand, the biological data demonstrated no significant change (p > 0.05).
