It is established that protein requirements are elevated in athletes to support their training and post-exercise recovery and adaptation, especially within skeletal muscle. However, research on the requirements for this macronutrient has been performed almost exclusively in younger athletes, which may complicate their translation to the growing population of Master athletes (i.e. > 35 years old). In contrast to older (> 65 years) untrained adults who typically demonstrate anabolic resistance to dietary protein as a primary mediator of the ‘normal’ age-related loss of muscle mass and strength, Master athletes are generally considered successful models of aging as evidenced by possessing similar body composition, muscle mass, and aerobic fitness as untrained adults more than half their age. The primary physiology changes considered to underpin the anabolic resistance of aging are precipitated or exacerbated by physical inactivity, which has led to higher protein recommendations to stimulate muscle protein synthesis in older untrained compared to younger untrained adults. This review puts forth the argument that Master athletes have similar muscle characteristics, physiological responses to exercise, and protein metabolism as young athletes and, therefore, are unlikely to have protein requirements that are different from their young contemporaries. Recommendations for protein amount, type, and pattern will be discussed for Master athletes to enhance their recovery from and adaptation to resistance and endurance training.

众所周知，运动员对蛋白质的需求会增加，以支持他们的训练和运动后的恢复和适应，尤其是在骨骼肌中。然而，对这种常量营养素需求的研究几乎只在年轻运动员中进行，这可能会使他们转化为不断增长的大师级运动员（即 > 35 岁）人群变得复杂。与未受过训练的年长（> 65 岁）成年人相比，他们通常表现出对膳食蛋白质的合成代谢抗性，作为“正常”与年龄相关的肌肉质量和力量损失的主要介质，大师级运动员通常被认为是成功的衰老模型，如下所示拥有与年龄超过一半的未经训练的成年人相似的身体成分、肌肉质量和有氧能力。与未经训练的年轻成年人相比，缺乏身体活动会促进或加剧被认为支持衰老合成代谢阻力的主要生理变化，这导致建议在未经训练的老年人中刺激肌肉蛋白质合成的蛋白质建议更高。这篇综述提出了这样的论点，即大师级运动员与年轻运动员具有相似的肌肉特征、对运动的生理反应和蛋白质代谢，因此不太可能有与年轻运动员不同的蛋白质需求。将为大师级运动员讨论蛋白质含量、类型和模式的建议，以提高他们从阻力和耐力训练中恢复和适应的能力。与未经训练的年轻成年人相比，这导致了更高的蛋白质建议，以刺激未经训练的老年人的肌肉蛋白质合成。这篇综述提出了这样的论点，即大师级运动员与年轻运动员具有相似的肌肉特征、对运动的生理反应和蛋白质代谢，因此不太可能有与年轻运动员不同的蛋白质需求。将为大师级运动员讨论蛋白质含量、类型和模式的建议，以提高他们从阻力和耐力训练中恢复和适应的能力。与未经训练的年轻成年人相比，这导致了更高的蛋白质建议，以刺激未经训练的老年人的肌肉蛋白质合成。这篇综述提出了这样的论点，即大师级运动员与年轻运动员具有相似的肌肉特征、对运动的生理反应和蛋白质代谢，因此不太可能有与年轻运动员不同的蛋白质需求。将为大师级运动员讨论蛋白质含量、类型和模式的建议，以提高他们从阻力和耐力训练中恢复和适应的能力。和蛋白质代谢作为年轻运动员，因此不太可能有与年轻同时代人不同的蛋白质需求。将为大师级运动员讨论蛋白质含量、类型和模式的建议，以提高他们从阻力和耐力训练中恢复和适应的能力。和蛋白质代谢作为年轻运动员，因此不太可能有与年轻同时代人不同的蛋白质需求。将为大师级运动员讨论蛋白质含量、类型和模式的建议，以提高他们从阻力和耐力训练中恢复和适应的能力。
