【摘要】：研究目的：随着生活水平的提高、生活方式的改变，肥胖已经成为全球性的人类公共健康问题。肥胖与体重控制的研究倍受关注。运动增加能量消耗量，可以起到防肥减肥的作用。运动的能量消耗不仅表现在运动中的能量消耗，而且在运动结束之后也会引起额外的能量消耗即EPOC（Excess Post-exercise Oxygen Consumption，运动后过量氧耗）。运动后EPOC的增加主要与运动后脂肪供能有关。因此，在运动对体重控制的研究中如何通过增加EPOC而增加运动总能耗量而倍受关注。本文采用不同强度时间组合但相同运动中能耗量的功率车运动干预，观察其对肥胖男青年运动后过量氧耗的影响，为更好的利用EPOC控制体重提供试验依据。研究方法：研究对象为9名无运动禁忌、无系统运动训练史的肥胖男性大学生。运动中能量消耗为300kcal（参考ACSM减肥运动处方指南），分别以70%、60%、40%的VO_2max强度进行功率车运动测试。其中有5人未完成70%VO_2max强度的运动测试，60%和40%VO_2max组各受试者全部完成。监测采用MAXII运动心肺测试系统，监测运动前、中和运动恢复期的HR、VO_2max、RER和恢复期EPOC量及持续时间等指标。统计方法采用PASW18.0软件，对数据进行重复测量方差分析，显著水平为p＜0.05。实验结果：①运动后EPOC的量三组分别为6471.91（1988.40）ml，7902.92（2863.10）ml，4618.90（1099.54）ml,其中40%VO_2与60%VO_2具有显著差异性（P=0.024），70%VO_2VS60%VO_2与70%VO_2VS40%VO_2组相比均无显著差异（P＞0.05），，但是60%VO_2有高于70%VO_2趋势。 ②EPOC持续时间23.76（3.03）min、31.95（2.80）min、32.26（6.23）min；70%VO_2与60%VO_2相比具有显著差异（P=0.000），70%VO_2与40%VO_2相比具有显著差异（P=0.034），40%VO_2与60%VO_2无显著差异（P=1.000）但是40%VO_2有EPOC持续时间有高于60%VO_2的趋势。 ③相同能耗量不同强度时间运动后对过量能耗40%VO_2VS60%VO_2具有显著差异性（P=0.030）；70%VO_2VS40%VO_2与70%VO_2VS60%VO_2均无显著差异性（P＞0.05）。不同强度时间的定量运动后机体的总耗能变化：70%VO_2VS40%VO_2有显著差异（P=0.004），40%VO_2VS60%VO_2具有显著差异性（P=0.000），70%VO_2VS60%VO_2无差异（P＞0.05）。结论：相同运动中能耗量（300kcal）的40%VO_2max、60%VO_2max和70%VO_2max强度时间组合的功率车运动，60%VO_2max运动方案运动能耗的高于其它两种方案。建议：在青年肥胖男性在运动减肥实践中可接受的范围内尽可能采用中等偏高强度的有氧运动，这样更有利于脂肪分解代谢。
[Abstract]:Objective: with the improvement of living standard and lifestyle, obesity has become a global public health problem. Obesity and weight control have attracted much attention. Exercise increases energy consumption. It can prevent fat and lose weight. The energy consumption of exercise is not only reflected in the energy expenditure in exercise, After exercise, it also caused additional energy consumption, EPOC(Excess Post-exercise Oxygen consumption, excess oxygen consumption after exercise. The increase of EPOC after exercise was mainly related to the energy supply of fat after exercise. How to increase the total energy consumption of exercise by increasing EPOC has attracted much attention in the study of body weight control by exercise. In this paper, the power vehicle exercise intervention with different intensity time combination but the same energy consumption in exercise is adopted. To observe the effect of EPOC on excess oxygen consumption after exercise in obese young men and provide experimental basis for better use of EPOC to control body weight. Methods: nine subjects without exercise taboos were studied. Obese male college students with no history of systematic exercise training. The energy expenditure in exercise is 300kcal (refer to the ACSM diet exercise prescription guide). The power car exercise test was conducted with a VO_2max intensity of 70 / 60g / 40% respectively. Among them, 5 of them did not complete the exercise of 70VO 2max intensity. All subjects in the 60% and 40 VOS2max groups were completed. The monitoring was performed with the MAXII exercise cardiopulmonary test system. HRVO _ 2maxRER, EPOC quantity and duration of recovery period were monitored before and after exercise. The statistical method used PASW18.0 software to carry out repeated measurement variance analysis of the data, the significant level was p < 0.05. The results of the experiment were as follows: the number of EPOC in the three groups was 6471.91 / 1988.40ml / s 7902.92n / 2863.10ml / 4618.90 / 1099.54ml / ml, respectively, and there was a significant difference between 40VO2 and 60VO2 as compared with 60VO2. There was no significant difference between the two groups (P > 0.05), but the level of 60VO2 was higher than that of 70VOVO / VS40 group (P > 0.05), but the level of 60VO2 was higher than that of 70VOVO2. 2The duration of EPOC is 23.76 / 3.03 / min / 31.95 / 2.80 / min / min ~ (32) 266.23 / min / min _ (70). There is a significant difference between P0.000T / S and 60VO2. There is no significant difference between P0.03440VO2 and 60VO2), but there is a trend that the EPOC duration of 40VO2 is higher than that of 60VO2 (P < 0.05). (2) there is no significant difference between P0.03440VO2 and 60VO2 (P 1.000), but there is a trend that the EPOC duration of 40VO2 is higher than that of 60VO2 (P < 0.05). (3) there is a significant difference in the excess energy consumption of 40VS60VO2 after the same energy consumption amount and different intensity time movement. There is a significant difference in the total energy consumption of 70VO2VS40VO2 in the aspect of 70VO2VS40VO2. There is no significant difference between the two levels (P > 0.05). There is a significant difference in total energy consumption of 70VO2VS40VO2 after the quantitative exercise at different intensity times. There are significant differences in the total energy consumption of 70VO2VS40VO2, P0.004VS40VO2 and 40VO2VS60VO2. There was no difference (P > 0.05) between VS60 and VO2VS60. Conclusion:. The energy consumption of 40 Vos _ 2max60 / VO _ 2max / VO _ 2max / VO _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max / V _ 2max. Recommendations:. In the range acceptable to young obese men in exercise and weight loss practice, moderate and high intensity aerobic exercise is adopted as far as possible, which is more advantageous to adipose catabolism.
