【摘要】：目的:了解低溫環(huán)境不同強(qiáng)度跑臺(tái)運(yùn)動(dòng)時(shí)能量消耗特點(diǎn),為冬季項(xiàng)目運(yùn)動(dòng)員的營(yíng)養(yǎng)補(bǔ)充和訓(xùn)練監(jiān)控提供理論依據(jù),也能夠?yàn)槎卷?xiàng)目愛好者的健身提供科學(xué)支撐。方法:選取北京體育大學(xué)有一定訓(xùn)練年限男生10人,采用交叉自身對(duì)照的實(shí)驗(yàn)方法在12℃左右的環(huán)境下進(jìn)行靜息、65%VO2max、80%VO2max強(qiáng)度跑臺(tái)運(yùn)動(dòng)三次測(cè)試。利用固定式氣體代謝儀對(duì)受試者測(cè)試過程中的氣體進(jìn)行采集,每次測(cè)試前后采集指血和靜脈血測(cè)定生化指標(biāo)。結(jié)果:(1)環(huán)境溫度為12℃,安靜時(shí)糖、脂供能比例基本相當(dāng),以65%VO2max強(qiáng)度進(jìn)行跑臺(tái)運(yùn)動(dòng)時(shí)糖的供能比例升高,以80%VO2max強(qiáng)度進(jìn)行跑臺(tái)運(yùn)動(dòng)時(shí)糖供能占總供能近90%;在靜息、65%VO2max和80%VO2max強(qiáng)度跑臺(tái)運(yùn)動(dòng)三種狀態(tài)中,以80%VO2max強(qiáng)度跑臺(tái)運(yùn)動(dòng)時(shí)總能耗和糖供能量最高,以65%VO2max強(qiáng)度跑臺(tái)運(yùn)動(dòng)時(shí)脂肪供能量最高。(2)80%VO2max強(qiáng)度跑臺(tái)運(yùn)動(dòng)20min后血乳酸值顯著升高。65%VO2max強(qiáng)度運(yùn)動(dòng)20min后血糖值的變化與靜息20min后相比具有顯著性差異。與靜息后相比,以65%VO2max和80%VO2max強(qiáng)度運(yùn)動(dòng)后血清游離脂肪酸(FFA)水平顯著升高。與運(yùn)動(dòng)前相比,以65%VO2max和80%VO2max強(qiáng)度運(yùn)動(dòng)后血清FFA水平顯著升高。(3)12℃環(huán)境下靜坐20min后,血清胰島素(Ins)、胰高血糖素(PG)水平顯著下降,Ins下降幅度更大,脂聯(lián)素(ADPN)水平顯著升高。與65%VO2max強(qiáng)度運(yùn)動(dòng)后相比,以80%VO2max強(qiáng)度進(jìn)行跑臺(tái)運(yùn)動(dòng)后血清兒茶酚胺類激素、Ins與瘦素(LP)水平具有顯著性差異。結(jié)論:(1)當(dāng)環(huán)境溫度為12℃時(shí):安靜時(shí)糖、脂供能比例基本相當(dāng),以65%VO2max強(qiáng)度進(jìn)行跑臺(tái)運(yùn)動(dòng)時(shí)糖的供能比例升高,當(dāng)以80%VO2max強(qiáng)度進(jìn)行跑臺(tái)運(yùn)動(dòng)時(shí)糖供能占總供能近90%;(2)在靜息、65%VO2max和80%VO2max強(qiáng)度跑臺(tái)運(yùn)動(dòng)三種狀態(tài)中,以80%VO2max強(qiáng)度跑臺(tái)運(yùn)動(dòng)時(shí)總能耗和糖供能量最高,以65%VO2max強(qiáng)度跑臺(tái)運(yùn)動(dòng)時(shí)脂肪供能量最高。
[Abstract]:Objective: to understand the characteristics of energy consumption in treadmill sports with different intensity in low temperature environment, and to provide theoretical basis for nutrition supplement and training monitoring of athletes in winter events. It can also provide scientific support for the fitness of winter sports enthusiasts. Methods: select 10 male students from Beijing physical Education University with a certain number of years of training. The experimental method of crossover self-control was used to carry out three tests on the intensity of running platform of 65VO2max80 and VO _ 2max in the environment of about 12 鈩，
