• Resumen

  • The purpose of this study was to determine the effectiveness of 16 weeks of continuous passive motion (CPM) or machine-assisted exercise as an alternative form of training on body composition, muscle strength, and flexibility in women aged 40�65 years. Thirty-one exercisers and 8 controls completed 16 weeks of training, with the exercisers averaging 3 sessions per week. Six toning tables targeted different muscle groups by moving the body and/or limbs while subjects attempted to resist the movements. Body composition was assessed by individual measures (dual energy x-ray absorptiometry, hydrodensitometry, and bioelectric impedance) and a 4-compartment model, flexibility was assessed by a Leighton flexometer and the sit and reach procedure, and strength was measured by standard 1 repetition maximum procedures before training began, after 5 weeks of training, and after 16 weeks of training. When the 2 groups were compared after week 5 and week 16 of training, few significant ( p < 0.05) group by trial differences were noted; however, these differences were minimal and represented little or no practical significance (very low effect sizes). In conclusion, CPM training did not appear to provide a sufficient stimulus to significantly alter measures of strength, flexibility, or body composition in women aged 40�65 years.
