大学生实施力量训练与外源营养摄入干预效果研究

Intervention Effect of Strength Training and Exogenous Nutrition Intake for Police College Students

通过研究男女大学生在力量训练后服用不同运动营养补充剂,分析其对身体机能恢复的影响。以48名湖北省某大学学生为试验对象,平均分成实验组和对照组,实验组为力量训练结合运动营养补剂的方式,对照组为单纯力量训练的方式,测定身体机能数据并采用SPSS22.0软件对结果进行分析。大学生服用不同的运动营养补充剂,力量训练后各身体质量指数基本无变化,而服用左旋肉碱实验组体重有一定下降;服用3种运动营养补充剂结合力量训练可以显著提高骨骼肌含量;服用营养补充剂对大学生的力量训练后的血常规指数影响较小,但有助于维持血红蛋白平衡;服用营养补充剂有助于力量训练后血乳酸值恢复至正常值,但其相对峰功率、相对平均功率和功率递减率与服用前相比均无显著性差异。服用营养补充剂对大学生力量训练后身体机能指标恢复有促进作用,该研究可以为力量训练人员的营养补充剂选择提供指导。

By studying the effects of different exercise nutrition supplements taken by male and female college students after strength training on physical function recovery,48 students from a university in Hubei Province were selected as experimental subjects and divided into an experimental group and a control group.The experimental group received strength training combined with exercise nutrition supplements,while the control group received strength training alone.Physical function data were measured and analyzed using SPSS 22.0 software.College students taking different sports nutrition supplements showed no significant changes in their body mass index after strength training,while the experimental group taking L-carnitine experienced a certain decrease in weight;Taking three types of sports nutrition supplements combined with strength training can significantly increase skeletal muscle mass;Taking nutritional supplements has a relatively small impact on the blood routine index of college students after strength training,but it helps maintain hemoglobin balance;Taking nutritional supplements can help restore blood lactate levels to normal after strength training,but there is no significant difference in relative peak power,relative average power,and power decline rate compared to before taking.Taking nutritional supplements can promote the recovery of physical function indicators in college students after strength training,and this study can provide guidance for the selection of nutritional supplements for strength training personnel.
