PURPOSE: To evaluate whether improvements in physical function are related to
changes in body composition after a three-month progressive resistance and
balance exercise program among individuals approximately one to three years after
stroke. METHODS: In this randomized controlled trial, 43 community-dwelling
subjects (65-85 years, mean age 73 +/- 5 years, 73% men) were allocated to a
progressive resistance and balance exercise program twice weekly for three months
(intervention group [IG], n = 20) or a control group (n = 23). The main outcome
measures were fat mass (kg) and fat-free mass (kg), as measured by bioelectrical
impedance analyses (Tanita((R))). Physical function was measured using the
six-minute walk test. RESULTS: Complete case analyses revealed reduced fat mass
in the IG compared with the control (-1.5 vs. (0).13% of body weight,
respectively; effect size =0.62; p = 0.048). In contrast, no between-group
difference in fat-free mass was observed. The six-minute walk test was improved
(25 vs. -10 m, respectively, effect size =0.69, p = 0.039) at three months in
favor of the IG. The reduced fat mass was associated with an improved six-minute
walk test (r = 0.48, p = 0.038) in the IG. CONCLUSIONS: Three-month progressive
resistance and balance training was associated with reduced fat mass, which was
related to improvements in walking capacity in older adults approximately one
year after stroke. Implications for rehabilitation This three-month PRB group
exercise program supported by motivational discussions and daily home-based
exercises indicate the following: * Improved walking capacity was associated with
a reduction in fat mass. * IGF-1 is reduced, possibly indicating improved insulin
sensitivity.
