Riassunto dello studio

Twenty-seven women diagnosed with osteosarcopenic adiposity (OSA) were randomized to undergo a 12 week progressive elastic band resistance exercise training (peRET) program (n=15) or control consisting of a 40 educational lecture on home exercise instructions, as well as an elastic band to take home (n=12). Outcomes of interest included body composition (i.e. body fat %, absolute muscle mass, lean mass, relative muscle mass, skeletal muscle mass, bone density of the spin) and physical capacity which was measured by functional forward reach (FFR), single leg stance (SLS), time up and go (TUG) test, time chair rise (TCR) test, grip strength, and gait speed. All outcomes were measured at 3 and 9 months follow-up. Results of this randomized controlled trial demonstrated that no statistically significant differences were observed for all body composition outcomes at both 3 and 9 months follow-up between the peRET program group and the control (p>0.05 for all). However, the TUG and TCR test results were statistically significantly in favour of the peRET group compared to the control at month 3 (p<0.05 for both), but not at 9 months follow up (p>0.05 for both). All remaining physical outcomes were not statistically significantly different between the two groups at 3 and 9 months follow-up period (p>0.05 for all).
