【摘要】：目的:观察补充蛋白棒在提高运动人体的运动能力、促进疲劳消除、调整机能状态等方面的功效。方法:将某部队24名男性士兵分成实验组、阳性对照组与阴性对照组三组,实验过程中每天实验组补充蛋白棒、阳性对照组补充蛋白粉、阴性对照组补充纤维棒,其他日常膳食内容相同。分别测试三组受试者经过11天使用蛋白棒及其对照品并进行相同力量训练前后的运动能力和生化指标。结果:实验组运动后次日清晨血清CK水平较实验前显著降低(P0.05),阴性对照组和阳性对照组则无显著性差异;实验组运动后次日清晨血清BU水平较实验前显著性降低(P0.05),阴性对照组则无显著性差异;实验组运动后次日清晨血清肌酐水平较实验前显著升高(P0.05),阴性对照组则无显著性差异。实验组和阳性对照组实验后杠铃卧推最大力量与实验前相比显著提高(P0.05),阴性和阳性对照组无显著性差异;实验组实验后杠铃深蹲最大力量与实验前相比显著提高(P0.05),而阴性对照组训练前后无显著性差异;实验组实验后1分钟引体向上次数较实验前显著提高,而另外两组训练前后则无显著性差异。结论:连续11天运动前后使用蛋白棒能够降低受试者运动后第二天晨CK水平、运动后即刻和第二天晨的血BU水平,促进肌肉合成代谢,加速肌肉恢复,同时帮助提高受试者上下肢、肩等部位的肌肉力量。
[Abstract]:Objective: to observe the effects of supplemental protein bars on improving exercise ability, promoting fatigue elimination and regulating functional state. Methods: 24 male soldiers in a certain army were divided into three groups: the positive control group and the negative control group. During the experiment, the experimental group was supplemented with protein rods, the positive control group supplemented with protein powder and the negative control group supplemented with fiber rods. Other daily meals are the same. The exercise ability and biochemical indexes of the three groups were tested before and after 11 days of using the protein rod and its reference substance and the same strength training. Results: the serum CK level in the experimental group decreased significantly the next morning after exercise (P0.05), but there was no significant difference between the negative control group and the positive control group. The serum BU level in the experimental group decreased significantly the next morning after exercise (P0.05), but there was no significant difference in the negative control group, while the serum creatinine level in the experimental group increased significantly the next day after exercise (P0.05), but there was no significant difference in the negative control group. After the experiment, the maximum force of barbell supine push in the experimental group and the positive control group was significantly higher than that before the experiment (P0.05), but there was no significant difference between the negative group and the positive control group. The maximum strength of barbell squatting in the experimental group was significantly higher than that before the experiment (P0.05), but there was no significant difference before and after training in the negative control group. There was no significant difference between the other two groups before and after training. Conclusion: the use of protein rods before and after 11 consecutive days exercise can reduce the CK level in the morning after exercise, blood BU level immediately after exercise and early morning exercise, promote the metabolism of muscle synthesis and accelerate the recovery of muscle. It also helps to increase muscle strength in the upper and lower limbs, shoulders, and so on.
