Abstract:
A comprehensive recent study by Trommelen et al. demonstrated that muscle tissue exhibits a greater capacity to incorporate exogenous exogenous protein-derived amino acids into bound muscle protein than was previously appreciated, at least when measured in \"anabolically sensitive,\" recreationally active (but not resistance-trained), young men following resistance exercise. Moreover, this study demonstrated that the duration of the postprandial period is modulated by the dose of ingested protein contained within a meal, that is, the postexercise muscle protein synthesis response to protein ingestion was more prolonged in 100PRO than 25PRO. Both observations represent important scientific advances in the field of protein metabolism. However, we respectfully caution that the practical implications of these findings may have been misinterpreted, at least in terms of dismissing the concept of protein meal distribution as an important factor in optimizing muscle tissue anabolism and/or metabolic health. Moreover, based on emerging evidence, this idea that the anabolic response to protein ingestion has no upper limit does not appear to translate to resistance-trained young women.
摘要:
Trommelen等人最近的一项综合研究。证明肌肉组织表现出比以前认识到的更大的将外源蛋白质衍生的氨基酸整合到结合的肌肉蛋白质中的能力,至少在“代谢敏感”中测量时,“娱乐活动(但不是抵抗训练),抵抗运动后的年轻人。此外,这项研究表明,餐后时期的持续时间是由膳食中摄入的蛋白质的剂量调节,也就是说,运动后对蛋白质摄入的肌肉蛋白质合成反应在100PRO中比25PRO中延长。这两种观察都代表了蛋白质代谢领域的重要科学进展。然而,我们恭敬地警告说,这些发现的实际含义可能被误解了,至少在消除蛋白质膳食分布作为优化肌肉组织合成代谢和/或代谢健康的重要因素的概念方面。此外,根据新出现的证据,这种认为对蛋白质摄入的合成代谢反应没有上限的想法似乎并不能转化为抵抗训练的年轻女性。
