【摘要】：研究目的:最大脂肪代谢强度在减脂健身中具有广泛的应用前景。本研究旨在比较研究最大脂肪代谢强度的常用测量方法,结合体质测量与评价理论,验证一次持续递增负荷试验信效度,以一次递增负荷试验实测最大脂肪代谢强度方法为校标的基础上,依托20米折返跑建立推测20~39岁成年人最大脂肪代谢强度的简易方法。简化最大脂肪代谢强度的测试方法,为大众科学减脂健身方案的制定提供方法学依据,方便该指标在大众健身领域中推广与应用。研究对象与方法:选取321名20~39岁成年人为研究对象,16人用于验证最大脂肪代谢强度的测量方法,分别进行最大摄氧量、血乳酸和最大脂肪代谢强度的测量。305名受试者测量身高、体重、肺活量等,20米折返跑测试及功率车测量最大脂肪代谢强度。利用皮尔逊相关、配对样本T检验、逐步回归方程等数理统计方法建立20米折返跑测量最大脂肪代谢强度的模型并进行检验。研究结果:1.一次递增负荷试验测量最大脂肪代谢强度的方法与经典的两次测量方法测得的最大脂肪代谢强度在0.01水平上显著相关(r=0.921),配对样本T检验结果显示两种方法无显著性差异(P0.05)。因此认为一次递增负荷试验测量最大脂肪代谢强度信效度较好。2.20米折返跑测得最大脂肪代谢强度与一次递增负荷试验测试结果在0.00的水平上显著相关(r=0.775),并且两次试验无显著性差异(P大于0.05),说明利用20米折返跑推测FATmax的方法有效。3.20米折返跑推测最大脂肪代谢强度的模型Y(FATamx)=0.057*20米折返跑级别+0.012*体重-0.010*年龄+0.004*握力-0.041,经过检验,模型有意义,且具有56.2%的解释力度。研究结论:1.本文同标准试验效标,验证了起始负荷25W,每级2分钟递增25W,转速60转/分钟的一次递增负荷试验简便、有效、可行,可作为大样本数据采集FATmax的标准试验,利于推广与应用,为科学的减脂健身、运动训练、缓解脂代谢性疾病提供靶强度。2.利用20米折返跑数据及最大脂肪代谢强度相关指标,建立回归模型,该模型准确、有效。20米折返跑测试简化了最大脂肪代谢强度的测试方法,为大众科学减脂健身方案的制定提供了方法学依据,方便了该指标在大众健身领域中的推广。
[Abstract]:Objective: the maximum fat metabolism intensity has a wide application prospect in reducing fat fitness. The purpose of this study was to compare the commonly used measurement methods of maximum fat metabolic intensity and to verify the reliability and validity of a continuous incremental load test combined with the theory of physical fitness measurement and evaluation. Based on the method of maximum fat metabolism intensity measured in an incremental load test, a simple method for estimating the maximum fat metabolic intensity of adults aged 20 ~ 39 years was established based on the 20m reverse run. To simplify the test method of maximum fat metabolism intensity, to provide the methodological basis for the formulation of mass scientific fat-reducing fitness program, and to facilitate the popularization and application of this index in the field of mass fitness. Subjects and methods: 321 adults aged 20 to 39 years were selected to measure the maximal fat metabolic intensity. The maximal oxygen intake, blood lactic acid and maximal fat metabolic intensity were measured respectively. Weight, vital capacity, etc. 20 meters back run test and power car to measure the maximum fat metabolic intensity. By using Pearson correlation, paired sample T test, stepwise regression equation and other mathematical statistical methods, a 20m reverse run model for measuring maximum fat metabolic intensity was established and tested. The result of the study was: 1. The maximum fat metabolic intensity measured by one incremental load test was significantly correlated with the maximum fat metabolic intensity measured by the classical twice measuring method at 0.01 level. The T test of paired samples showed no significant difference between the two methods (P 0.05). It is concluded that the reliability and validity of a single incremental load test for measuring the maximum fat metabolic intensity is good. 2.20 m reverse run shows that the maximum fat metabolic intensity is significantly correlated with the results of one incremental load test at the level of 0.00, and the maximum fat metabolic intensity is significantly correlated with that of the single incremental load test at the level of 0.00, and twice. There was no significant difference in the test (P > 0.05), which showed that the method of predicting FATmax by 20m reverse race was effective. The model of predicting maximum fat metabolism intensity by 3.20m reverse race was 0.012 * body weight -0.010 * age 0.004 * grip strength -0.041. The model is meaningful and has 56.2% explanation. Conclusion: 1. In the same standard test, it is proved that the initial load is 25W, the speed is 60 rpm, the initial load is 25W, the rotational speed is 60rpm, and the test is simple, effective and feasible. It can be used as the standard test for large sample data acquisition FATmax, which is helpful for popularization and application. Provide target strength. 2. 2 for scientific lipid-reducing fitness, exercise training and alleviating lipid metabolic diseases. The regression model was established by using the data of 20m reverse race and the related indexes of maximum fat metabolism intensity. The model is accurate and effective. The test of .20m reverse race simplifies the test method of maximum fat metabolism intensity. It provides a methodological basis for the formulation of scientific fat-reducing fitness program, and facilitates the popularization of the index in the field of mass fitness.
