【摘要】：随着社会的飞速发展,大众生活条件越来越高,由此带来肥胖的问题也逐年增加。特别是近年来,由于肥胖引起的相关代谢疾病患病率呈直线上升的趋势。肥胖已成为一种慢性的代谢疾病。肥胖的分类有很多种,根据脂肪分布的位置分为外周型肥胖和向心型肥胖。由肥胖引起的相关代谢疾病很多都与内脏脂肪堆积过多有关系,因此如何有效减少内脏脂肪对改善肥胖患者身体健康有着重要的意义。近年来高强度间歇运动对改善身体健康的效果成为大众研究的热点。一些研究表明,高强度间歇训练能够有效提高有氧能力、降低血糖、提高胰岛素敏感性、改善血管内皮功能和减少身体脂肪含量。高强度间歇训练与中等强度持续训练相比,由于运动时间短、节奏变化快,因此更容易被大众接受。相关研究提示,高强度间歇运动能够有效减少腹部皮下脂肪量和内脏脂肪量。但是高强度间歇运动的方案较多,其中大部分的运动时间较长,对一些久坐少动的肥胖人群来说,他们更偏向选择短时间大强度间歇训练,但是在高强度间歇训练优化方案方面的研究较少,目前还没有找到一个减肥效率特别高的方案,因此高强度间歇运动方案值得深入研究。研究目的:比较分析短时间大强度间歇训练与其它两种训练方案对肥胖青年女性腹部皮下脂肪量、内脏脂肪量、全身脂肪量和有氧能力的影响,为运动减肥提供理论指导,同时也为肥胖人群减肥提供一种新的选择。研究方法:58名肥胖青年女性(Fat%:38.59±2.6%)随机分为4组:S组、H组、M组、C组,干预12周。S组的运动方案为短时间大强度间歇运动,使用Monark 894无氧功率自行车,进行全力冲刺6s间歇9s的运动;间歇过程无负荷,空蹬功率自行车。每冲刺6s间歇9s即完成一组,共需完成80组。M、H组均使用Monark 839有氧功率自行车,克服相同机械功,前2周每次运动克服机械功为200kj,后10周每次运动克服机械功300kj。M组的运动强度为60%VO2peak强度持续运动,H组的运动强度为90%VO2peak强度的间歇运动。H组以90%VO2peak强度运动4分钟后间歇,间歇过程中不运动,当主观体力感觉(Rating of Perceived Exertion,RPE)下降到13时,再进行4分钟运动。运动干预期间,所有受试者保持与运动干预前相同的饮食和体力活动习惯。12周运动干预结束后用双能x射线和计算机断层扫描(computedtomography,ct)分别对全身脂肪含量和腹部皮下脂肪和内脏脂肪进行测量。研究结果:1.除vo2peak外,所有初始指标各组均无统计学差异(p0.05),三个运动组之间vo2peak无统计学差异(p=0.64)。2.12周干预前后腹部皮下脂肪和内脏脂肪面积比较12周干预后s组腹部内脏脂肪面积减少了9.1%(69.27±23.43cm2vs62.95±21.85cm2,p=0.042),h组内脏脂肪面积减少了13.4%(68.96±24.71cm2vs59.87±19.09cm2,p=0.019);s组和h组变化值之间无交互作用(p=0.831);m组12周干预前后内脏脂肪面积无显著性差异(69.4±26.63cm2vs60.21±23.52cm2,p=0.053);c组12周干预前后内脏脂肪面积有减少的倾向,但无统计学意义上的差异(69.81±21.30cm2vs69.43±19.49cm2,p=0.725)。12周干预后s组腹部皮下脂肪面积减少7.1%(244.89±62.27cm2vs227.54±51.83cm2,p=0.040),h组腹部皮下脂肪面积减少14.1%(248.43±61.19cm2vs213.37±51.03cm2,p=0.005),m组腹部皮下脂肪面积减少12.9%(219.87±47.56cm2vs191.58±35.50cm2,p=0.008),且三组变化值之间无交互作用(p=0.797,p=0.145,p=0.234),c组腹部皮下脂肪面积无显著性差异(302.62±91.18cm2vs299.72±92.72cm2,p=0.373)。3.实验组fat%、全身脂肪量和体重变化情况12周干预后s组、h组、m组fat%(s组:38.41±2.33%vs36.34±2.12%,p=0.000;h组:38.14±2.28%vs35.62±1.98%,p=0.000;m组:38.00±2.13%vs35.64±2.33%,p=0.000)、全身脂肪量(s组:25.67±3.45kgvs23.68±3.33kg,p=0.000;h组:25.72±3.28kgvs22.85±3.04kg,p=0.000;m组:38.00±2.13kgvs35.64±2.33kg,p=0.000)、体重(s组:66.68±6.41kgvs64.94±6.15kg,p=0.000;h组:67.33±6.09kgvs64.00±5.99kg,p=0.000;m组:68.52±8.00kgvs65.14±7.72kg,p=0.000)均有显著性降低,且三组变化值之间均无交互作用。c组运动干预后fat%、全身脂肪量、体重均无显著性差异(p=0.973,p=0.437,p=0.462)。4.实验组vo2peak变化情况12周干预后S组、H组、M组VO2peak水平均有显著性提高(S组:30.75±3.54ml/min/kg VS 38.50±4.79ml/min/kg,P=0.000;H组:31.49±2.17 ml/min/kg VS 39.79±4.48 ml/min/kg,P=0.000;M组:30.61±3.53 ml/min/kg VS 38.33±4.44ml/min/kg,P=0.000),且三组变化值之间均无交互作用。C组运动干预后VO2peak水平无显著性差异(27.62±2.81ml/min/kg VS 27.56±2.20 ml/min/kg,P=0.936)。结论经过12周干预,短时间大强度间歇训练与其它两种运动方式相比,运动时间短、减肥效果好,能够有效减少肥胖青年女性全身脂肪量、Fat%,特别是对减少腹部脂肪量有着良好效果,同时还能提高最大摄氧量水平,为肥胖人群运动减肥提供了一种新的选择。
[Abstract]:With the rapid development of society, the public life condition is more and more high, resulting in the problem of obesity is also increasing year by year. Especially in recent years, due to a linear increase in prevalence rate of metabolic diseases caused by obesity. Obesity has become a chronic metabolic disease. There are many kinds of classification of obesity, according to fat distribution the location is divided into peripheral obesity and obesity related metabolic disorders to heart. Many are caused by obesity and visceral fat excessive accumulation of a relationship, so how to effectively reduce the visceral fat is important to improve the health of obese patients. In recent years, high-intensity intermittent exercise to improve the physical health effects has become a hot research mass. Some studies have shown that high intensity intermittent training can improve aerobic capacity, reduce blood sugar, improve insulin sensitivity, improve endothelial function and reduce body fat Content. High intensity interval training and continuous medium intensity training, because the movement time is short, fast rhythm changes, so more easily accepted by the public. The related studies suggest that high-intensity intermittent exercise can effectively reduce abdominal subcutaneous fat and visceral fat weight. But high intensity intermittent exercise program more, most of the long time movement among them, some of the sedentary obese people, they tend to choose high intensity interval training in short time, but in the high intensity intermittent training optimization research has yet to find a weight loss of very high efficiency scheme, so the high intensity intermittent exercise program deserves further study. The purpose of the study: a comparative analysis high intensity intermittent training time and the other two kinds of training program for obese young women abdominal subcutaneous fat, visceral fat mass, body fat mass and aerobic capacity The effect of weight loss, to provide theoretical guidance for the movement, but also provides a new choice for weight loss in obese individuals. Methods: 58 obese young women (Fat%: 38.59 + 2.6%) were randomly divided into 4 groups: S group, H group, M group, C group,.S 12 week exercise program intervention group for a short time and high intensity intermittent exercise, the use of Monark 894 anaerobic power bicycle, full sprint 6S intermittent 9s movement; batch process without load, empty pedal power bicycle. Each 9s is a complete 6S intermittent sprint group were required to complete the 80 group.M, H group were using Monark 839 aerobic power bicycle, overcome the same the mechanical work, the first 2 weeks of each exercise to overcome the mechanical energy is 200kj, 10 weeks after each exercise exercise intensity to overcome the mechanical power group 300kj.M 60%VO2peak intensity endurance exercise, exercise intensity in the H group.H group 90%VO2peak intermittent exercise intensity to 90%VO2peak intensity exercise after 4 minutes of intermittent, intermittent process Do not exercise, when perceived exertion (Rating of Perceived Exertion, RPE) dropped to 13, then 4 minutes of exercise. Exercise intervention period, all subjects maintained and exercise intervention diet and physical activity habits.12 weeks after the end of the same exercise intervention by dual energy X ray and computer tomography (computedtomography CT) measurements were performed on the body fat content and abdominal subcutaneous fat and visceral fat. Results: 1. in addition to VO2peak, there was no significant difference in all indexes of each group (P0.05), initial VO2peak no statistical difference between the three exercise group (p=0.64) before and after.2.12 weeks of intervention of abdominal subcutaneous fat and visceral fat area compared to 12 weeks the intervention group s abdominal visceral fat area was reduced by 9.1% (69.27 + 23.43cm2vs62.95 + 21.85cm2, p=0.042), H group of visceral fat area was reduced by 13.4% (68.96 + 24.71cm2vs59.87 + 19.09cm2, p=0.019); Group s and H No interaction between group variation (p=0.831); group M, visceral fat area had no significant difference before and after 12 weeks of intervention (69.4 + 26.63cm2vs60.21 + 23.52cm2, p=0.053); C group before and after 12 weeks of intervention of visceral fat area tended to be decreased, but no statistically significant difference in the (69.81 + 21.30cm2vs69.43 + 19.49cm2, p=0.725).12 weeks after the intervention group s abdominal subcutaneous fat area decreased by 7.1% (244.89 + 62.27cm2vs227.54 + 51.83cm2, p=0.040), 14.1% H group reduced abdominal subcutaneous fat area (248.43 + 61.19cm2vs213.37 + 51.03cm2, p=0.005), 12.9% M group reduced abdominal subcutaneous fat area (219.87 + 47.56cm2vs191.58 + 35.50cm2, p=0.008), and the three groups change value no interaction (p=0.797, p=0.145, p=0.234), the C group has no significant difference in abdominal subcutaneous fat area (302.62 + 91.18cm2vs299.72 + 92.72cm2, p=0.373).3. fat% in the experimental group, body fat and body weight changes 12鍛ㄥ共棰勫悗s缁，
