背景：有氧运动中蛋白质的利用可能有益于正常体重成年人的有氧能力和身体成分。然而，尚不清楚超重/肥胖个体是否会引起类似的适应或改善其他心脏代谢/健康相关标志物以响应不同类型的蛋白质。因此，我们的目的是研究在未经训练的超重或肥胖受试者中，补充两种不同的蛋白质饮料并结合运动对有氧能力、身体成分和血液健康标志物的影响。研究方法：本研究测量了未经训练的超重/肥胖男性在6周内的训练适应和健康参数（n = 28; BMI 30.4 ± 2.2 kg/m2）（燕麦/马铃薯; n = 8）或动物源性（牛奶; n = 10）蛋白质-碳水化合物饮料（10克蛋白质/份），或对照碳水化合物饮料（n = 10），在每次训练之前和之后急性（平均三次训练/周，70%HRmax）。干预前后，肌肉活检和血液样本收集，身体成分测量（DXA）和两个不同的运动测试进行。体重得到控制，参与者在整个干预过程中保持体重稳定。结果如下：对于组合的组，训练干预显著增加（8%; P < 0.001），在力竭时间试验中的表现（~ 100%; P < 0.001），线粒体蛋白质含量和酶活性（~20-200%）。瘦体重增加1%（P < 0.01），脂肪减少3%（P < 0.01）。未观察到对空腹血糖、胰岛素、血脂或免疫功能标志物的显著影响。对于训练适应或血液测量来说，饮酒条件之间没有显着的相互作用。对于体成分，燕麦/马铃薯和碳水化合物组比牛奶组显著减少腿部脂肪量（交互作用P < 0.05）。结论：有氧能力和身体组成得到改善，一些线粒体，糖酵解和氧化骨骼肌蛋白和酶活性上调6周的训练干预。然而，没有一个耐力训练适应参数的影响，蛋白质补充之前和之后的每次训练。
Background: Protein availability around aerobic exercise might benefit aerobic capacity and body composition in normal weight adults. However, it is unknown if individuals with overweight/obesity elicit similar adaptations or improve other cardiometabolic/health-related markers in response to different types of protein. Thus, our aim was to study the effect of supplementation of two different protein drinks in conjunction with exercise on aerobic capacity, body composition and blood health markers in untrained subjects with overweight or obesity. Methods: The present study measured training adaptation and health parameters over a 6 week period in untrained men with overweight/obesity (n = 28; BMI 30.4 ± 2.2 kg/m2) ingesting either plant- (Oat/Potato; n = 8) or animal-based (Milk; n = 10) protein-carbohydrate drinks (10 g of protein/serving), or a control carbohydrate drink (n = 10) acutely before and after each training session (average three sessions/week @ 70% HRmax). Pre-post intervention , muscle biopsies and blood samples were collected, body composition measured (DXA) and two different exercise tests performed. Body weight was controlled with participants remaining weight stable throughout the intervention. Results: For the groups combined, the training intervention significantly increased (8%; P < 0.001), performance in a time-to-exhaustion trial (~ 100%; P < 0.001), mitochondrial protein content and enzyme activity (~20–200%). Lean body mass increased (1%; P < 0.01) and fat mass decreased (3%; P < 0.01). No significant effects on fasting blood glucose, insulin, lipids or markers of immune function were observed. There were no significant interactions between drink conditions for training adaptation or blood measurements. For body composition, the Oat/Potato and carbohydrate group decreased leg fat mass significantly more than the Milk group (interaction P < 0.05). Conclusions: Aerobic capacity and body composition were improved and a number of mitochondrial, glycolytic and oxidative skeletal muscle proteins and enzyme activities were upregulated by a 6 week training intervention. However, none of the parameters for endurance training adaptation were influenced by protein supplementation before and after each training session.
