【摘要】：基于运动训练过程中能量代谢的角度,研究马拉松运动训练的过程中,糖与脂肪协调供能系统的最佳运动训练负荷强度的区间。通过机体在运动过程中呼吸交换率(呼吸商RER)的变化趋势,对运动员在运动过程中,运动训练负荷强度对糖与脂肪协调供能的最佳氧化区间的影响;在此基础上对马拉松运动项目进行研究,探讨运动负荷训练强度与糖脂协调供能的相关调节机制。运用文献资料法、跟踪观察法、数理统计法和实验测试法对宁夏马拉松队的运动员的专项训练情况进行研究,通过场地最大摄氧量与无氧阈的测试方法,对宁夏马拉松运动员自身的最大摄氧量(VO2max)摄氧量(VO_2)、二氧化碳呼出量(VCO_2)、呼吸商(RER=VCO_2/VO_2)、心率(HR)、通气无氧阈(AT)、脂肪氧化率和碳水化合物的氧化率等测试指标进行整理与分析。实验测试研究发现:通过呼吸商在马拉松运动中的应用研究,在马拉松的运动训练中,如果用呼吸商来界定其糖脂协调供能的区间,呼吸商界定的范围为0.73-0.99,在训练中呼吸商的范围所对应的训练负荷强度即是糖与脂肪协调供能的区间,呼吸商在0.73-0.99这个区间会出现一个糖与脂肪协调供能的最佳点且在运动训练实践中有很大的指导意义。结论:1.在马拉松运动项目中,呼吸交换率在0.73-0.99这个区间时为马拉松的糖脂供能区间。2.在马拉松运动项目中,负荷运动过程中机体呼吸交换率为0.84左右时,其所对应的负荷强度为马拉松的糖脂协调供能区间的最佳训练负荷强度。3.糖脂协调训练对马拉松运动员最大摄氧量(VO2max)的能力有维持能力的积极作用,并提高机体对氧的利用率;对马拉松运动员无氧阈(AT)的能力有提高的变化趋势;对马拉松运动员测试总时间(成绩)有提高的变化趋势;对马拉松运动员的最大心率影响不大;对马拉松运动员糖脂协调供能能力的提高有较大的影响。
[Abstract]:Based on the point of view of energy metabolism in the course of sports training, the optimum training load intensity of the coordinated energy supply system of sugar and fat was studied in the course of marathon training. According to the changing trend of respiratory exchange rate (RERA) during exercise, the effect of exercise training load intensity on the optimal oxidation interval of coordinated energy supply between sugar and fat was studied. On this basis, the marathon events were studied, and the related regulation mechanism between the intensity of exercise load training and the coordinated energy supply of sugar and lipids was discussed. The special training of Ningxia Marathon athletes was studied by the methods of literature, tracking and observation, mathematical statistics and experimental test. The test methods of maximal oxygen uptake and anaerobic threshold were used. The test indexes such as maximal oxygen intake (VO _ 2max) of Ningxia marathon athletes (VO _ 2max), CO _ 2 exhalation and VCO _ 2C _ (2), respiratory quotient (RERA) VCO _ (2) / V _ (O _ 2), heart rate (HR), ventilation anaerobic threshold (ATN), fat oxidation rate and carbohydrate oxidation rate were analyzed. The experimental results show that: through the application of respiratory quotient in marathon training, if the respiratory quotient is used to define the range of sucrose and lipids coordinated energy supply, The range of respiratory quotient is 0.73-0.99.The training load intensity corresponding to the range of respiratory quotient in training is the interval of coordinated energy supply between sugar and fat. Respiratory quotient (RQ) in the range of 0.73-0.99 will have an optimal point of coordinated energy supply between sugar and fat, and it has great guiding significance in the practice of exercise training. Conclusion 1. In marathons, respiratory exchange rates range from 0. 73-0. 99 for marathon sugars and lipids. In the marathon, when the respiratory exchange rate of the body is about 0.84, the corresponding load intensity is the best training load intensity of the coordinated energy supply range of sugar and lipids in the marathon. The coordinated training of sugar and lipids can maintain the ability of maximal oxygen intake of marathon athletes and improve the utilization rate of oxygen in the body. It has a tendency to improve the total test time (results) of marathon athletes; has little effect on the maximum heart rate of marathon runners; and has a great influence on the improvement of the ability of sugar and lipid coordinated energy supply of marathon runners.
