Impact of different nutritional approaches on sarcopenia: a protocol for systematic review and network meta-analysis

Abstract

AbstractAlthough it is known that proper nutrition is effective in managing sarcopenia, the most powerful nutrients have not yet been determined. This study is designed to investigate the effects of various nutritional approaches on muscle mass, muscle strength, and sarcopenia prevention in systematic reviews. In study design, network and pairwise meta-analyses of randomized clinical trials were considered. Clinical studies regarding the nutritional effects associated with the physiological activity of skeletal muscle and management of sarcopenia will be covered. The main outcomes will cover the following five elements: anti-fatigue impact with skeletal muscle, muscle atrophy prevention, differentiation level with skeletal muscular cell, anti-inflammatory effect, and muscle injury prevention. Authors will conduct the study selection, extracting data process, and methodological quality investigation.Systematic review registrationOSF registry (ethical approval number: https://osf.io/ye4q7).
