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 ( = 0.01), while those taking WPr had an improvement of 11.1% ( = 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.
动物源乳清蛋白（WPr）是消费者中最受欢迎的蛋白质补充剂，已被证明可以增加肌肉质量和力量。然而，由于过敏、饮食限制/个人选择以及需求的增长，有必要寻找替代蛋白质来源。久坐的成年人被随机分配到豌豆蛋白（PPr）或 WPr 中，并与每周的阻力训练计划一起进行 84 天。评估了全身肌肉力量（WBMS）的变化，包括握力、下肢和上肢力量、身体成分和产品感知。安全性结果包括不良事件、生命体征、临床化学和血液学。在 WBMS、肌肉质量或产品感知和喜爱评分方面，PPr 和 WPr 组之间没有显著差异。补充 PPr 的参与者在补充 84 天后 WBMS 提高了 16.1%（ = 0.01），而服用 WPr 的参与者提高了 11.1%（ = 0.06）。在纳入的人群中，两种研究产品均安全且耐受良好。在健康久坐的成年人中，与阻力训练计划相结合，84 天的 PPr 补充可提高力量和肌肉质量，与 WPr 相当。在不牺牲肌肉收益和产品享受的情况下，PPr 可以被认为是动物源 WPr 的可行替代品。
