Lu Y, et al. - Researchers performed a systematic review and a meta-analysis of randomized controlled trials (RCTs) to determine how muscle fitness, including muscle mass, muscle strength, and physical performance, in patients on dialysis, is influenced by exercise performed. They analyzed overall 21 eligible RCTs identified from five English and 4 Chinese databases. According to pooled data, a significant improvement in leg mass was brought about by resistance training whereas such an improvement was not seen with aerobic training. A significant increase in both grip strength and knee extension strength was offered by resistance training. Findings are suggestive of the possible improvement in muscle mass and muscle strength in relation to regular resistance training with a moderate to high intensity in patients undergoing dialysis, particularly for the trained muscles. An improved physical performance may be achieved in dialysis patients with the help of both aerobic training and resistance training.
