Body composition and physical function after progressive resistance and balance training among older adults after stroke
(English)Article in journal (Other academic) Submitted
Purpose: To study the effects of a progressive resistance and balance (PRB) exercise program on body composition with regard to its associations with physical function among individuals approximately one year after stroke.
Method: A total of 43 individuals from the community (age 73 years (SD 5.0), 73% men) were randomly assigned either to an intervention group (IG, n=20) that received a PRB exercise program twice weekly for three months or a control group (CG, n=23). The primary objectives were to correlate potential changes in the fat-free mass (FFM (kg) and FFM index (FFMI) (kg/m2), and fat-mass (FM (kg), (%) of body weight, FMI (kg/m2)), as measured by bioelectrical impedance analyses (Tanita®), with physical function, including walking capacity; i.e., the 6 Min Walk Test; 6MWT, balance and mobility.
Results: At three months, a complete case analyses revealed a significant reduction in fat mass per cent in the intervention group when compared with the control group; -1.5 vs. 0.13 % respectively; effect size, ES=0.62 standard error (SE), 0.80; P=0.0.39). No between-group differences in FFM were observed. There was a between-group difference in the 6MWT (25 vs. -10 m) at three months in favor of the IG (r=0.47, P=0.04). Changes in FMI were associated with improved walking capacity in the IG.
Conclusions: Three months of PRB training might reduce fat mass in older adults approximately one year after stroke. This exploratory study indicated an association between improvements in physical performance and changes in body fat mass.
