Effect of aerobic training versus resistance training for improving cardiorespiratory fitness and body composition in middle-aged to older adults: A systematic review and meta-analysis of randomized controlled trials.
Abstract
This systematic review and meta-analysis aimed to examine the influence of aerobic training (AT) versus resistance training (RT) on cardiorespiratory fitness and body composition in middle-aged to older adults. Four electronic databases including PubMed, Scopus, Cochrane CENTRAL, and web of science, as well as reference lists of included randomized controlled trials (RCTs) were searched from inception to April 2024. Data were pooled by the inverse-variance method and reported as mean differences (MDs) with 95 % confidence intervals (CIs). Thirty-eight RCTs, with a pooled sample of 1682 participants, met our inclusion criteria. Meta-analysis revealed that AT significantly improved VO

Research summary
The paper is relevant to longevity research as it investigates the effects of different types of exercise on cardiorespiratory fitness and body composition in middle-aged to older adults, which are important factors in promoting healthy aging and potentially extending lifespan. However, while the findings contribute to our understanding of exercise's role in aging, they represent a solid but incremental advance rather than a groundbreaking discovery.
