【摘要】：目的:检测便携式能量消耗测试仪SenseWear Armband(SWA)应用于职业足球运动员在不同强度奔跑时能量消耗测量的有效性。方法:9名职业女子足球运动员(19.3±1.3岁),至少空腹2小时,静坐10分钟后上跑步机先后以四种不同强度的速度(50%VO_(2max)、65%VO_(2max)、75%VO_(2max)、85%VO_(2max))跑步10分钟,每个强度完成以后受试者休息直至心率恢复到110次/分钟再开始下一个强度的测试。采用便携式心肺功能测试仪Cosmed K4b2记录受试者的气体交换情况,同时采用SWA记录受试者的能量消耗。结果:配对t检验结果显示,除了70%VO_(2max)(相对应的代谢当量为10 METs),在其它三个强度运动时,SWA和Cosmed K4b2的每分钟数据均具有显著性差异(P0.001)。与Cosmed K4b2测量结果相比,在56%VO_(2max)时,SWA显著高估了热量消耗,而在79%VO_(2max)和87%VO_(2max)时,SWA显著低估了热量消耗。当运动强度以能量代谢当量表示时,测量误差值的绝对值在10 METs左右达到最小。SWA和CosmedK4b2在9~11 METs间的每分钟数据显著相关(P0.05)并无显著差异性(P=0.365),而在小于9 METs或大于11 METs的运动强度区间时,SWA和Cosmed K4b2的每分钟数据显著相关并具显著差异性(P0.001)。结论:SWA在10 METs代谢当量附近监测热量消耗最为准确,此强度也是职业女足比赛时的常见强度。因此,虽然SWA在检测低于9 METs和高于11 METs能量代谢当量强度的运动时的热量消耗误差渐增,但可有效地应用于女足运动员在比赛中的热量消耗测定。
[Abstract]:Objective: to test the effectiveness of the portable energy expenditure tester (SenseWear Armband SWA) in measuring the energy expenditure of professional soccer players when running with different intensity. Methods: nine professional women soccer players were measured by 19.3 卤1.3 years old, at least 2 hours on an empty stomach. After 10 minutes of sitting on the treadmill, at four different speeds of different intensities, you will have to run for 10 minutes at a speed of 50 per cent, at a speed of four different intensities, and at a speed of about 65 Vox, and at a speed of 65 Vox, and at 2max.75 Vox, and then on the running machine.) for 10 minutes, you can run for 10 minutes. After each intensity was completed, the subjects rested until the heart rate returned to 110 beats per minute before starting the next intensity test. A portable cardiopulmonary function tester, Cosmed K4b2, was used to record the gas exchange of the subjects. At the same time, SWA was used to record the energy expenditure of the subjects. Results: the results of the paired t test showed that, With the exception of 70 Vos / 2max1 (the corresponding metabolic equivalent is 10 METsN), there is a significant difference in the data per minute between SWA and Cosmed K4b2 during the other three intensity exercises. Compared with the results of the Cosmed K4b2 measurement, SWA significantly overestimates heat consumption at 56VOD _ 2max. The SWA significantly underestimated the energy consumption at 79-V _ 2max. when the exercise intensity was expressed as the equivalent of energy metabolism, The absolute value of the measurement error value reached the minimum SWA at about 10 METs and the significant correlation between the CosmedK4b2 and the data per minute between 9 and 11 METs (P0.05). There was no significant difference in the absolute value between SWA and CosmedK4b2 in the range of exercise intensity of less than 9 METs or greater than 11 METs (P0.05), but the difference between SWA and CosmedK4b2 was not significant in the range of exercise intensity less than 9 METs or greater than 11 METs. There was significant correlation between clock data and significant difference (P 0.001). Conclusion the monitoring of energy consumption at 10 METs metabolic equivalent is the most accurate. This intensity is also a common intensity in professional women's football competitions. Therefore, while SWA tests for activities with energy metabolism equivalent below 9 METs and above 11 METs energy metabolism equivalent, the error of caloric consumption is increasing. However, it can be used effectively to measure the heat consumption of women football players in the competition.
