Eight Weeks of Resistance Training Is Not a Sufficient Stimulus to Improve Body Composition in Post-COVID-19 Elderly Adults.
Study Goal
The researchers aimed to assess the effects of 8 weeks of resistance training on body mass and body composition in post-COVID-19 elderly adults and to compare the agreement between BIA and DXA methods for measuring body composition.
Results Summary
The study found no significant changes in body mass or body composition after 8 weeks of resistance training. BIA overestimated baseline body mass and fat-free mass while underestimating fat mass compared to DXA, but both methods showed no significant differences in tracking intervention-induced changes.

Background: This study sought to assess how body mass (BM) and body composition in post-COVID-19 elderly adults were affected by 8 weeks of resistance training. An additional goal was to determine the agreement between Bioelectrical Impedance Analysis (BIA) and Dual Energy X-Ray Absorptiometry (DXA) in elderly people. Methods: Participants were randomly assigned to an intervention Group, which engaged in 8 weeks of resistance training, and a Control Group, which was advised to maintain their usual activity levels. Before and after the intervention, the body composition was analyzed via the BIA and DXA methods. Results: We found no statistically significant changes in BM or body composition following resistance training. BIA was found to overestimate the participants' baseline BM and fat-free mass (FFM) and to underestimate the fat mass (FM), compared to the DXA method. There were no significant differences in intervention-induced changes in FM and FFM measured by BIA and DXA. Conclusions: Moderate intensity resistance training lasting 8 weeks was not found to be a sufficient stimulus to improve BM and body composition in post-COVID-19 elderly adults. We also conclude that BIA may serve as a viable alternative to DXA for measuring longitudinal changes in body composition in elderly people.
