【摘要】：目的：论文旨在探讨健身跑运动对机体气体代谢和能量消耗的影响以及运动前、后递增负荷过程中气体代谢与能量消耗指标的变化特征的规律,为今后能更系统更科学地进行健身跑锻炼奠定基础,并为提高我国中年女性体质健康水平提供科学依据。方法：通过社会招募选取自愿参与健身跑锻炼的西安市50-59岁女性,共36名作为实验组受试对象,并进行16周健身跑运动干预。观察运动干预前后,机体在安静状态时、无氧阈状态时以及递增负荷运动过程中各指标的变化情况。测试指标主要有心率(HR)、摄氧量(VQ)、二氧化碳呼出量(VCQ)、相对摄氧量(VO2/kg)、通气量(VE)、氧通气当量(VE/VO2)乎吸频率(RF)、氧脉搏(VQ/HR)、代谢当量(NETS)、乎吸交换率(RER)、能耗。所有数据均采用SPSS17.0统计软件和Mcrosoft Excel 2003软件进行处理分析,结果以平均数±标准差表示。运用描述统计、定基比、配对样本T检验分析方法进行统计处理。P0.05为显著性差异,P0.01为非常显著性差异。结果：(1)安静状态下,HR、VO2、VCO2、VO2/kg、RER、METS和能耗指标运动干预后较干预前显著降低;VE和RF与运动干预前相比无显著性差异。(2)无氧阈所对应的HR、VO2、VE、VO2/HR和METS均显著增加,且到达无氧阈的时间和功率也显著增加。(3)递增负荷运动过程中各指标变化特征的比较,运动开始时运动干预后VQ增长速度大于运动干预前,VCO2、VE和RF较干预前增长速度降低;中等强度运动时,干预后VE、METS曾长速度大于干预前,干预后的能耗小于干预前;高强度运动时,VO2增长速度以及平均值均大于运干预前,且干预后的能耗、METS均大于干预前;力竭时,干预后VO2、 VCO2、VE、METS、能耗的值均大于干预前;恢复期时,干预后VO2、VCO2、VE、VO2/kg、RF、METS、能耗下降速度均大于干预前。结论：(1)安静状态下的HR、VO2、VCO2、VO2/Kg、RER指标较运动干预前显著降低,表明16周健身跑运动使50-59岁女性的心率降低,呼吸系统功能得到有效的改善,增强了机体的心肺功能。(2)16周健身跑运动使50-59岁女性的无氧阈所对应的HR、VO2、VE、VO2/HR、METS、到达无氧阈的时间和功率均明显增加,使机体的有氧工作能力增强。(3)16周健身跑运动也可明显改善递增负荷运动过程中机体的气体代谢能力,表现在机体机能动员快,耐力长,冲刺强,通气效率提高,有氧利用更经济性;中低等强度运动时,干预后的能耗小于干预前,表明50-59岁女性16周健身跑运动后对中低运动强度表现出了运动的经济性;16周健身跑运动还可增强机体的恢复能力。
[Abstract]:Objective: to explore the effect of fitness running on gas metabolism and energy consumption and the characteristics of gas metabolism and energy consumption in the process of increasing load before and after exercise. It will lay a foundation for more systematic and scientific running exercise in the future and provide scientific basis for improving the physique and health level of middle-aged women in China. Methods: 36 women (50 to 59 years old) who volunteered to take part in running exercise in Xi'an were recruited as subjects of the experimental group, and 16 weeks of exercise intervention were carried out. The changes of indexes before and after exercise intervention were observed when the body was in the quiet state, the anaerobic threshold state and the increasing load exercise. The main test indexes were heart rate (HR), oxygen uptake (VQ), carbon dioxide exhalation (CO _ 2) and VCQ _ (n), relative oxygen uptake (V _ O _ 2 / kg ~ (-1), ventilation volume (V / V _ (2), oxygen ventilation equivalent (V / V _ (2), oxygen pulse rate (VQ / H), metabolic equivalent (NETS), absorption exchange rate (R _ (2) / kg ~ (-1), energy consumption. All the data are analyzed by SPSS 17.0 and Microsoft Excel 2003 software. The results are expressed as mean 卤standard deviation. Using descriptive statistics, fixed base ratio, paired sample T-test analysis method for statistical treatment. P0.05 is significant difference. P0.01 is a very significant difference. Results (1) there was no significant difference in V E and RF between before and after exercise intervention. The HRV _ 2V _ 2V _ 2V _ (2 / kg) V _ (2 / kg) V _ (2) O _ (2) and energy consumption indexes after exercise intervention were significantly lower than those before exercise intervention. There was no significant difference between before and after intervention. (2) HRV _ (2) VEV _ (2) HR and Mets, corresponding to the anaerobic threshold, were significantly increased. The time and power to reach anaerobic threshold were also significantly increased. Compared with the change characteristics of each index during incremental load exercise, VQ increased faster after exercise intervention at the beginning of exercise than VCO _ 2VE and RF before exercise intervention. In moderate intensity exercise, the energy consumption after intervention was longer than that before intervention, and the energy consumption after intervention was lower than that before intervention, and the growth speed and mean value of VO2 during high intensity exercise were higher than those before intervention, and the energy consumption after intervention was higher than that before intervention. After intervention, the values of VO2, VCO2VEVEMETS, energy consumption were higher than those before intervention, and during the recovery period, VCO2VCO2VEV VO2 / kg / kg RFMETS, the energy consumption decreased faster than that before intervention. Conclusion the RER index of HRVO _ 2 / VCO _ 2V _ 2 / KgGN _ 2 / KG _ (1) in quiet state was significantly lower than that before exercise, which indicated that the heart rate of women aged 50 to 59 was decreased and the respiratory system function was improved effectively after 16 weeks of exercise. The body's cardiopulmonary function was enhanced by 16 weeks of exercise. The time and power of reaching the anaerobic threshold of HRVO _ 2VEV _ 2 / HRMETS, which were corresponding to the anaerobic threshold of women aged 50-59, were significantly increased. The aerobic working ability of the body was enhanced. The fitness running for 16 weeks could also obviously improve the gas metabolism ability of the body during the process of incremental load exercise, which was manifested in the quick mobilization, long endurance, strong sprint and improved ventilation efficiency of the body. Aerobic utilization is more economical, and the energy consumption after intervention is less than that before intervention. The results showed that the women aged 50 to 59 years old showed the economy of running 16 weeks after 16 weeks exercise, and the recovery ability of the body could be enhanced by 16 weeks running.
