Skeletal muscle mass losses with age are associated with negative health consequences, including an increased risk of developing metabolic disease and the loss of independence. Athletes adopt numerous nutritional strategies to maximize the benefits of exercise training and enhance recovery in pursuit of improving skeletal muscle quality, mass, or function. Importantly, many of the principles applied to enhance skeletal muscle health in athletes may be applicable to support active aging and prevent sarcopenia in the healthy (non-clinical) aging population. Here, we discuss the anabolic properties of protein supplementation in addition to ingredients that may enhance the anabolic effects of protein (e.g. omega 3 s, creatine, inorganic nitrate) in older persons. We conclude that nutritional strategies used in pursuit of performance enhancement in athletes are often applicable to improve skeletal muscle health in the healthy older population when implemented as part of a healthy active lifestyle. Further research is required to elucidate the mechanisms by which these nutrients may induce favourable changes in skeletal muscle and to determine the appropriate dosing and timing of nutrient intakes to support active aging.

随着年龄的增长，骨骼肌质量损失与负面健康后果有关，包括患代谢疾病的风险增加和失去独立性。运动员采用多种营养策略来最大限度地发挥运动训练的益处并促进恢复，以追求改善骨骼肌质量、质量或功能。重要的是，许多用于增强运动员骨骼肌健康的原则可能适用于支持积极老龄化和预防健康（非临床）老龄化人群的肌肉减少症。在这里，我们讨论了蛋白质补充剂的合成代谢特性以及可能增强老年人蛋白质合成代谢作用的成分（例如欧米茄 3 s、肌酸、无机硝酸盐）。我们得出结论，当作为健康积极生活方式的一部分实施时，用于提高运动员表现的营养策略通常适用于改善健康老年人的骨骼肌健康。需要进一步的研究来阐明这些营养素可能导致骨骼肌发生有利变化的机制，并确定营养素摄入的适当剂量和时间以支持积极衰老。
