背景：虽然大豆蛋白可能有许多健康益处来自其相关的抗氧化剂，许多男性锻炼者避免大豆蛋白。这部分是由于一个流行的，但未经检验的概念，在男性，大豆是不如乳清在促进肌肉重量增加。这项研究提供了一个直接的大豆产品和乳清product.Methods之间的比较：瘦体重增加进行了检查，男性从一所大学的重量训练班给予每日服务的微量营养素强化蛋白棒含有大豆或乳清蛋白（33克蛋白质/天，9周，n = 9，每个蛋白质治疗组）。训练使用的锻炼，每组重复次数相当低。从类（N = 9）的对照组做的训练，但没有消耗任何类型的蛋白棒。结果：大豆和乳清治疗组均显示出瘦体重的增加，但只训练组没有。乳清和训练组，但不是大豆组，表现出潜在的有害的训练后的影响两个抗氧化剂相关的相关parameters.Conclusions：大豆和乳清蛋白棒产品都促进运动训练诱导瘦体重增加，但大豆有额外的好处，保留两个方面的抗氧化功能。
Background: Although soy protein may have many health benefits derived from its associated antioxidants, many male exercisers avoid soy protein. This is due partly to a popular, but untested notion that in males, soy is inferior to whey in promoting muscle weight gain. This study provided a direct comparison between a soy product and a whey product.Methods: Lean body mass gain was examined in males from a university weight training class given daily servings of micronutrient-fortified protein bars containing soy or whey protein (33 g protein/ day, 9 weeks, n = 9 for each protein treatment group). Training used workouts with fairly low repetition numbers per set. A control group from the class (N = 9) did the training, but did not consume either type protein bar.Results: Both the soy and whey treatment groups showed a gain in lean body mass, but the training-only group did not. The whey and training only groups, but not the soy group, showed a potentially deleterious post-training effect on two antioxidant-related related parameters.Conclusions: Soy and whey protein bar products both promoted exercise training-induced lean body mass gain, but the soy had the added benefit of preserving two aspects of antioxidant function.
