补充瓜氨酸与运动相结合:对老年人肌肉功能的影响(CITEX 研究) (CITEX)
2021年8月3日 更新者:Mylène Aubertin-Leheudre、Université du Québec a Montréal
瓜氨酸补充剂结合运动对老年肥胖男性和女性肌肉功能和功能能力的影响
本研究的主要目的是确定口服补充瓜氨酸与 HIIT 相结合时,是否可以对老年肥胖男性和女性的身体成分、肌肉质量、肌肉代谢和功能能力产生显着变化。
研究人员假设,瓜氨酸与 HIIT 相结合将比单独使用 HIIT 更有益,HIIT 比单独使用瓜氨酸更有益,这比单独使用安慰剂对肥胖的老年男性和女性更有益。
研究概览
详细说明
瓜氨酸是一种非蛋白质氨基酸,从西瓜中分离出来,参与尿素循环和精氨酸前体。 参与者将服用 10 克/天的瓜氨酸或安慰剂(等热量)。
高强度间歇训练 (HIIT) 是一种高强度有氧训练(85% 的 HRmax 30 秒 + 65-70% 的 HRmax 1 分钟 30)。 他们 HIIT 持续时间为 30 分钟/会话。 HIIT 被认为有利于改善人体健康,例如最大摄氧量、体脂或。
然后将在连续 12 周内进行干预。
