【摘要】：目的:通過檢測(cè)封閉式運(yùn)動(dòng)減肥訓(xùn)練營中肥胖青少年血管內(nèi)皮功能及RAAS系統(tǒng)主要成分的變化,揭示運(yùn)動(dòng)結(jié)合飲食控制改善肥胖青少年血管內(nèi)皮功能的生物學(xué)機(jī)制。方法:32名男性單純性肥胖青少年,年齡:15.38±2.82歲,BMI:33.21±4.23 kg/m~2。接受為期6周的運(yùn)動(dòng)結(jié)合飲食控制,采用Endo PAT-2000系統(tǒng)測(cè)試受試者實(shí)驗(yàn)前后的指端反應(yīng)性充血指數(shù)(RHI),并對(duì)血清NO、內(nèi)皮素(ET-1)、腎素(PRA)、血管緊張素Ⅱ(AngⅡ)、血管緊張素原(AGT)、血管緊張素轉(zhuǎn)換酶(ACE)、醛固酮(ALD)水平、身體形態(tài)、糖脂代謝、血壓進(jìn)行檢測(cè)。結(jié)果:經(jīng)過6周運(yùn)動(dòng)結(jié)合飲食控制干預(yù),肥胖青少年身體成分、圍度和糖脂代謝指標(biāo)明顯改善。RHI(P0.01)和血清中NO/ET-1(P0.01)顯著上升,血清PRA、AngⅡ和ALD(P0.05、P0.01和P0.01)顯著下降。運(yùn)動(dòng)結(jié)合飲食控制干預(yù)前后血清PRA、AngⅡ和ALD的變化程度呈顯著正相關(guān),而AngⅡ與RHI變化程度呈顯著負(fù)相關(guān)(r=-0.562,P=0.003)。結(jié)論:肥胖青少年RAAS系統(tǒng)活性顯著提高。6周的運(yùn)動(dòng)結(jié)合飲食控制,能夠有效改善肥胖青少年的血管內(nèi)皮功能,其機(jī)制可能與運(yùn)動(dòng)結(jié)合飲食控制降低了RAAS系統(tǒng)活性有關(guān)。
[Abstract]:Aim: to investigate the changes of vascular endothelial function and the main components of RAAS system in obese adolescents in a closed exercise training camp to reveal the biological mechanism of improving vascular endothelial function in obese adolescents by exercise combined with diet control.Methods 32 male obese adolescents, aged 15. 38 鹵2. 82 years, were enrolled in the study. BMI: 33. 21 鹵4. 23 kg 路m ~ (-1) 路m ~ (2).After six weeks of exercise and diet control,The fingertip reactive hyperemia index (RHI) was measured by Endo PAT-2000 system before and after the experiment.
