Protein recommendations are provided on a daily basis as defined by the recommended dietary allowance (RDA) at 0.80 g protein/kg/day. However, meal-based, as opposed to daily, dietary protein recommendations are likely more informative given the role of the daily protein distribution pattern in modulating the post-exercise muscle protein synthetic response. Current protein meal recommendations to plateau post-exercise muscle protein synthesis rates are based on the ingestion of isolated protein sources, and not protein-rich whole foods. It is generally more common to eat whole food sources of dietary protein within a normal eating pattern to meet dietary protein requirements. Yet, there is a need to define how dietary protein action on muscle protein synthesis rates can be modulated by other nutrients within a food matrix to achieve protein requirements for optimal muscle adaptations. Recent developments suggest that the identification of an "optimal" protein source should likely consider the characteristics of the protein and the food matrix in which it is consumed. This review aims to discuss recent concepts related to protein quality, and the potential interactive effects of the food matrix, to achieve optimal protein requirements and elicit a robust postprandial muscle protein synthetic response with an emphasis on the post-exercise recovery window.
蛋白质的推荐摄入量是按推荐膳食供给量(RDA)来定义的,即每天 0.80g/kg。然而,基于日常饮食蛋白质分布模式在调节运动后肌肉蛋白质合成反应中的作用,基于餐次的而不是每日的蛋白质推荐摄入量可能更有意义。目前,为了使运动后肌肉蛋白质合成速率达到平台期,人们提出了一些关于蛋白质餐的建议,这些建议基于摄入分离的蛋白质来源,而不是富含蛋白质的全食物。在正常的饮食模式中,人们通常更倾向于食用全食物来源的膳食蛋白质来满足蛋白质的需求。然而,需要确定在食物基质中,其他营养素如何调节膳食蛋白质对肌肉蛋白质合成速率的作用,以满足最佳肌肉适应性的蛋白质需求。最近的研究表明,确定“最佳”蛋白质来源可能需要考虑蛋白质的特性和它所消耗的食物基质。本综述旨在讨论与蛋白质质量相关的最新概念,以及食物基质的潜在交互作用,以实现最佳的蛋白质需求,并在强调运动后恢复窗口的情况下引发强烈的餐后肌肉蛋白质合成反应。
