title: Effects of a progressive resistance exercise program with high-speed component on the physical function of older women with sarcopenic obesity: a randomized controlled trial.
abstract: BACKGROUND
  Sarcopenic obesity is associated with disability in older people, especially in women. Resistance exercises are recommended for this population, but their efficacy is not clear.
  
  
  OBJECTIVE
  To evaluate the effects of a progressive resistance exercise program with high-speed component on the physical function of older women with sarcopenic obesity.
  
  
  METHODS
  Twenty-eight women 65 to 80 years old, with a body mass index ≥30kg/m2 and handgrip strength ≤21kg were randomly allocated to two groups. The experimental group underwent a 10-week resistance exercise program designed to improve strength, power, and endurance of lower-limb muscles, with open chain and closed chain exercises. The control group had their health status monitored through telephone calls. The primary outcomes were lower limb muscle performance measured by knee extensor strength, power and fatigue by isokinetic dynamometry, and mobility measured by the Short Physical Performance Battery and by gait velocity. The secondary outcome was health-related quality of life assessed by the SF-36 Questionnaire.
  
  
  RESULTS
  The average rate of adherence was 85%, with few mild adverse effects. There were no significant between-group differences for any of the outcomes.
  
  
  CONCLUSIONS
  In this study, a progressive resistance exercise program with high-speed component was not effective for improving the physical function of older women with sarcopenic obesity.
