摘要
目的:明确蛋白强化的营养制剂是否能改善高运动量人员体内骨骼肌的含量及营养状况。方法:将40名高运动量人员分为试验组和对照组,分别给予水解蛋白粉强化的营养制剂和不含蛋白粉的果汁。在试验期间,保持原有训练强度不变。在试验开始前1 d和第8天,观察战士的体重、体质指数、静息能量代谢、呼吸商、骨骼肌、蛋白质、脂肪群、血清尿素氮、前清蛋白和转铁蛋白等的变化。结果:试验组战士的骨骼肌含量、蛋白质和血清尿素氮显著升高,脂肪群含量显著降低,前清蛋白、转铁蛋白升高。对照组战士的体质指数显著下降。结论:蛋白强化的营养制剂能增加骨骼肌含量,改善营养状况。
Objective： To observe whether the protein-enriched and easily absorbed nutritional agents can improve the muscle and nutrition condition.Methods： The single-blind randomized trial was used.40 people taking the high-physical exertion were divided into experimental and control groups.The people in the experimental group took the protein-entriched agents and the people of control group took the fruit juice without protein.During the experiment,they kept the training intensity.Before and the 8th day after the experiment,the rest energy expense,the body composition blood urea nitrogen,prealbumin and transferrin were examined.Results： The muscle,protein and blood urea nitrogen elevated significantly and the fat mass decreased significantly in experimental group.The BMI ofthe control group people after the experiment was lower than before.Conclusion： The protein-enriched and easily absorbed nutritional agents can increase muscle mass and improve the nutrition condition in the people taking the high-physical exertion.
