Special Issue Information
The present Special Issue aims to join efforts towards the comprehension of the effects of nutrition and physical exercise on skeletal muscle physiology, injury, and recovery, using different experimental models (cells, animals, and humans) in both healthy and pathological conditions. Of particular interest, studies addressing cellular and molecular mechanisms involved in these processes, including energy metabolism, inflammatory pathways, oxidative stress regulation, mitochondrial function alteration, and gene expression control are welcome. We also welcome papers targeting the identification of cellular and molecular targets of nutritional interventions and physical exercise for the treatment and/or prevention of skeletal muscle injury and recovery.

Abstract: Objective: To determine the effectiveness of whey protein supplementation during resistance exercise training (RET) versus RET with or without placebo on skeletal muscle mass and strength, and physical performance in older people with sarcopenia. Methods: Electronic searches in the PubMed, Embase, Scopus, Web of Science, LILACS, SPORTdiscus, Epistemonikos, and CINAHL databases were performed until January 20, 2023. Randomized clinical trials conducted in sarcopenic adults from 60 years or older, were included. The studies had to compare the effectiveness of the addition of supplements based on concentrated, isolated, or hydrolyzed whey protein (WP) during RET and compare it with RET with or without placebo on skeletal muscle mass and strength changes. The study selection process, data extraction, and risk of bias assessment were carried out by two independent reviewers. Results: Seven randomized clinical trials (591 participants) were included and five of them provided data for quantitative synthesis. The overall pooled standardized mean difference (SMD) estimate did not show statistically significant differences between RET plus WP versus RET with or without placebo for skeletal muscle mass, according to appendicular muscle index (SMD = 0.25; 95% CI, -0.01 to 0.50; P = 0.06; I2 = 41.86%, P = 0.142) and appendicular skeletal muscle mass (MD = 0.96 Kg; 95% CI, -0.61 to 2.54; P = 0.23; I2 = 61.19%, P = 0.076). The overall pooled SMD estimate showed statistically significant differences in favor of the RET plus WP group for handgrip strength (SMD = 0.64; 95% CI, 0.16 to 1.11; P = 0.008; I2 = 81.85%, P < 0.001). The narrative synthesis revealed discordance between the results of the studies on physical performance. Conclusions: The WP supplementation during RET is effective in increasing handgrip strength in people with sarcopenia compared to RET with or without placebo. However, no differences were found for skeletal muscle mass. The evidence quality was very low according to the GRADE approach. Further research is needed in this research field.
