Abstract：
Animal-sourced whey protein (WPr) is the most popular protein supplement among consumers and has been shown to improve muscle mass and strength. However, due to allergies, dietary restrictions/personal choices, and growing demand, alternative protein sources are warranted. Sedentary adults were randomized to pea protein (PPr) or WPr in combination with a weekly resistance training program for 84 days. Changes in whole-body muscle strength (WBMS) including handgrip, lower body, and upper body strength, body composition, and product perception were assessed. The safety outcomes included adverse events, vital signs, clinical chemistry, and hematology. There were no significant differences in the change in WBMS, muscle mass, or product perception and likability scores between the PPr and WPr groups. The participants supplemented with PPr had a 16.1% improvement in WBMS following 84 days of supplementation (p = 0.01), while those taking WPr had an improvement of 11.1% (p = 0.06). Both study products were safe and well-tolerated in the enrolled population. Eighty-four days of PPr supplementation resulted in improvements in strength and muscle mass comparable to WPr when combined with a resistance training program in a population of healthy sedentary adults. PPr may be considered as a viable alternative to animal-sourced WPr without sacrificing muscular gains and product enjoyment.
摘要：
动物来源的乳清蛋白（WPr）是消费者中最受欢迎的蛋白质补充剂，并已被证明可以改善肌肉质量和力量。然而,由于过敏,饮食限制/个人选择，不断增长的需求，替代蛋白质来源是必要的。久坐的成年人被随机分为豌豆蛋白（PPr）或WPr，并每周进行84天的阻力训练计划。全身肌肉力量（WBMS）的变化，包括手柄，下半身,和上身力量，身体成分,和产品感知进行了评估。安全性结果包括不良事件，生命体征,临床化学，和血液学。WBMS的变化没有显著差异,肌肉质量，或PPr和WPr组之间的产品感知和可爱度评分。补充PPr的参与者在补充84天后WBMS改善了16.1%(p=0.01)，而服用WPr的患者则提高了11.1%(p=0.06)。两种研究产品在登记人群中均安全且耐受性良好。在健康久坐的成年人群体中，与阻力训练计划相结合，补充84天的PPr可改善与WPr相当的力量和肌肉质量。PPr可以被认为是动物来源的WPr的可行替代品，而不会牺牲肌肉增益和产品享受。
