【摘要】：研究目的:HIIT作为热门健身方式,其减脂效果受到国内外科研者广泛关注。本研究通过8周HIIT、MCT,选用无运动训练经历的健康男性,旨在比较两组的体成分、静息代谢率及运动后过量氧耗阶段脂供能相关指标的变化特征,进而分析训练前后产生差异的脂供能因素,探讨HIIT减肥方法对健康男性青年的应用效果与可靠性,为大众运动健身减脂开拓新的思路。研究方法:本研究将18名健康青年男性随机分为H组、M组各9名。训练采用跑台,每周3次,一次30分钟,共8周,且在中期对强度进行校正。H组采用90%V02max强度,运动3分钟、间歇2分钟,共6组;M组采用60%V02max强度,运动30分钟。对各组受试者的安静状态、运动之前、运动过程中和运动结束恢复期这四个阶段进气体和生化代谢的测量。主要监测项目有体成分、RMR、TG、FFA、血清甘油、EPOC总量及持续时间。所有数据采用SPSS18.0软件进行处理,数据采用MEAN土SD表达。对组内和组间干预前后的指标统计方法分别为配对样本T检验、独立样本T检验。其中,训练期间的血液指标采用重复测量方差分析。当P0.05时为显著性统计学差异。研究结果:1干预后,仅H组体脂率(%)、腹部脂肪质量(kg)显著性下降。2干预后,H组RMR(kcal/kg·d)显著性提升。3 H组EPOC持续时间及总量、脂肪氧化量、总能耗、脂肪供能比例均显著性大于M组。4干预后,H组过量氧耗期间RER、FFA变化幅度显著性大于M组,提示,HIIT有利于运动后恢复期脂肪动员的加强。研究结论:1 HIIT和MCT都能起到降低体脂率、减少腹部脂肪质量、提升静息代谢率的作用。2 HIIT对健康青年男性产生的EPOC总量、持续时长显著性大于MCT。3相比MCT,8周的HIIT尤其对快恢复期(AS0-10)脂肪氧化量、慢恢复期(AS10-30)总能量消耗影响较大。4 EPOC与FFA代谢密切相关,相比MCT,HIIT更利于此阶段的脂肪动员、脂肪供能。
[Abstract]:Objective: as a popular fitness method, the effect of reducing fat on HIIT was widely concerned by researchers both at home and abroad. The purpose of this study was to compare the body composition of the two groups by 8 weeks HIITT MCTT and healthy male without exercise training experience. The characteristics of metabolic rate of rest and the related indexes of lipid supply during the period of excessive oxygen consumption after exercise were analyzed. The factors of lipid supply before and after training were analyzed, and the effect and reliability of HIIT weight-loss method on healthy young men were discussed. In this study, 18 healthy young men were randomly divided into H group (n = 9) and M group (n = 9). In the middle period, the intensity of group H was corrected with 90 V 02max intensity, 3 minutes of exercise and 2 minutes of interval. Group M was treated with 60 V 02max intensity and 30 minutes of exercise. Measurement of gas and biochemical metabolism in the four stages during exercise and during the recovery period after exercise. The main monitoring items were RMR-TG-FFA.The total amount and duration of serum glycerol were measured. All the data were processed by SPSS18.0 software. The data were expressed by MEAN soil SD. The index statistical methods before and after intergroup intervention were matched sample T test and independent sample T test respectively. The blood indexes during training were measured repeatedly by ANOVA. There was significant statistical difference when P05 was used. After intervention, the RMR(kcal/kg 路d of group H significantly increased the duration and total amount of EPOC, the amount of oxidation of fat, and the total energy consumption. The ratio of fat to energy supply was significantly higher than that of group M during the period of excessive oxygen consumption after intervention, suggesting that it was beneficial to the enhancement of fat mobilization in the recovery period after exercise. Conclusion both HIIT and MCT can decrease the rate of body fat in group M, and the ratio of FFA in group H is significantly higher than that in group M during the period of excessive oxygen consumption. The effects of decreasing abdominal fat quality and increasing resting metabolic rate on the total amount of EPOC produced by 2. 2 HIIT in healthy young men were significantly longer than that of HIIT in 8 weeks of MCT.3, especially in the fast recovery period. The total energy consumption of AS10-30) was closely related to the metabolism of FFA, which was more favorable for fat mobilization and fat energy supply than MCT-HIIT.
