文题释义:

高强度间歇运动:是指进行多次短时间高强度运动训练,在每2次训练之间以相对较低的强度运动或者完全无负荷休息形成间歇期,常采用全力冲刺或90%左右最大摄氧量强度。单组运动时间和间歇期可持续几秒到几分钟不等,按间歇周期长短可分为短间歇高强度间歇运动和长间歇高强度间歇运动。
气体代谢:是指机体消耗氧和产生二氧化碳的过程。组织细胞在生命活动过程中需要不断获取能量,其来源是体内营养物质(蛋白质、糖类和脂肪)的氧化。为维持体内正常的氧化过程,需经常供给氧和排出二氧化碳。测定单位时间内氧耗量和二氧化碳产生量可计算出能量代谢率。
摘要
背景:
研究发现高强度间歇运动比中等强度持续运动对于腹部脂肪的减少有更好的效果且更具时效性。
目的:以能量代谢的角度,探讨相同强度及时间下不同间歇方式的高强度间歇运动对肥胖女青年能量消耗及底物代谢的影响。
方法:采用气体代谢分析仪对7名肥胖青年女性在2次不同间歇形式的高强度间歇运动中的气体代谢情况进行分析。受试者需完成3次测试,第1次进行最大摄氧量测试。随后随机顺序进行后续2次运动测试:①90%VO2peak强度低频的高强度间歇运动(低频组);②90%VO2peak强度高频的高强度间歇运动(高频组)。每次运动之间间隔1周且运动时间避开受试者卵泡早期。运动干预方案获河北师范大学体育学院伦理委员会批准。参与试验的个体均为自愿参加,对试验过程完全知情同意。
结果与结论:①运动后高频组的血乳酸浓度显著小于低频组(P < 0.01),高频组糖酵解供能和无氧糖酵解的供能量显著低于低频组(P < 0.01);②运动期高频组的脂肪供能量、糖供能量、总的能量消耗均显著低于低频组(P < 0.05或P < 0.01),间歇期高频组的糖供能量要高于低频组(P < 0.05),脂肪供能量和总能量消耗也显著高于低频组(P < 0.01);③恢复期时高频组的脂肪供能量显著低于低频组(P < 0.05),训练期和全部时期总和的脂肪供能量显著高于低频组(P < 0.05);④结果说明,高强度间歇运动时间频率的改变能够减少血乳酸的堆积,促进脂肪的动员及氧化,在相同的能耗量下,改变了糖脂供能比例。

Abstract:

BACKGROUND: Compared with the moderate-intensity continuous movement, high-intensity interval training is more time-sensitive and effective for reducing abdominal fat.
OBJECTIVE: To investigate the effects of different forms of high-intensity interval training at the same intensity and time on energy expenditure and substrate metabolism in obese young women from the perspective of energy metabolism.
METHODS: The gas metabolism of seven obese young women in two different intermittent forms of high-intensity intermittent exercise was analyzed by gas metabolism analyzer. The subjects underwent thrice test: maximal oxygen uptake, 90%VO2peak at low-frequency high-intensity interval training (low-frequency group), and 90%VO2peak at high-frequency high-intensity interval training (high-frequency group). Exercise was performed once every 1 week and early follicle was avoided. The study was approved by the Ethics Committee of Sports Institute of Hebei Normal University. The subjects participated in the study voluntarily, and signed the informed consent.
RESULTS AND CONCLUSION: (1) The blood lactate concentration, glycolysis energy supply and anaerobic glycolysis energy supply after exercise in the high-frequency group were significantly lower than those in the low-frequency group (all P < 0.01). (2) The fat energy supply, sugar energy supply and total energy expenditure during exercise in the high-frequency group were significantly lower than those in the low-frequency group (P < 0.05 or P < 0.01). The sugar energy supply at interval time in the high-frequency group was significantly higher than that in the low-frequency group (P < 0.05), and the fat energy supply and total energy expenditure in the high-frequency group were significantly higher than those in the low-frequency group (P < 0.01). (3) The fat energy supply at convalescent period in the high-frequency group was significantly lower than that in the low-frequency group (P < 0.05), and the total fat energy supply in the high-frequency group was significantly higher than that in the low-frequency group (P < 0.05). (4) These results indicate that intermittent frequency changes during high-intensity interval training can reduce the accumulation of blood lactic acid, promote the mobilization and oxidation of fat, and change the ratio of glycolipid energy supply under the same energy consumption.
