RESISTANCE TRAINING FOR MUSCLE STRENGTH AND LEAN MASS IN ADULTS OLDER THAN 60 YEARS ? A SYSTEMATIC REVIEW

Objectives : Verify the effect of resistance training (RT) in muscle mass and muscle strength in older adults. Methods : Randomized Controlled Trials (RCT ) published between 2005 and 2015, with a study population aged 65 and up that went through an RT based intervention were analysed . Body composition should be assessed by Dual Energy X - ray Absorptiometry or Computed Tomography Scan. Internal validity of each article was assessed using the PEDro scale. Results : Five RCTs whit score of 5/10 met the inclusion criteria and globally 162 participants were assessed. Each study was based on a RT program of 6 - 16 weeks of 2 - 3 times/week. Discussion Main results show that high intensity and even low intensit y RT, increased muscle mass, cross sectional area, strength of the quadriceps and functionality. RT has shown great outcomes in preventing sarcopenia. Results magnitude is proportional to RT characteristics
