【摘要】：大強(qiáng)度間歇訓(xùn)練(HIIT)作為熱門健身方式,其對身體健康的影響受到國內(nèi)外學(xué)者的廣泛關(guān)注,與中等強(qiáng)度持續(xù)訓(xùn)練(MCT)相比,相似訓(xùn)練量下的兩種方式對心肺功能及有氧運動能力的作用一直受到眾多研究者爭議。本研究擬通過HIIT與MCT,以普通年輕男性為研究對象,比較兩種運動方式對心肺功能及運動能力的影響。研究對象為18名健康普通男性大學(xué)生(中高強(qiáng)度運動時間,MVPA=43.36±24.61min/d,無系統(tǒng)訓(xùn)練),年齡21.65±1.53歲,身高179.30±6.43cm,體重78.17±12.64kg。隨機(jī)分成HIIT(n=9)與MCT(n=9)組,分別測量體脂率(Fat%),肺功能及安靜狀態(tài)下的心臟彩超、靜息攝氧量及最大攝氧量(GXT測試,初始速度為8km/h,每3min速度增加1km/h,當(dāng)速度超過12km/h后,每級速度不變,增加1%坡度,直至受試者無法堅持),期間每級負(fù)荷末測血乳酸。得到最大攝氧量(VO2max)數(shù)據(jù)后進(jìn)行每周3次,持續(xù)8周的訓(xùn)練。HIIT方案:90%VO2max訓(xùn)練3min,以25%VO2max間歇2min,往復(fù)6組。MCT方案:持續(xù)以60%VO2max運動30min。8周訓(xùn)練結(jié)束后進(jìn)行相同的測量。所有結(jié)果用均數(shù)±標(biāo)準(zhǔn)差表示,訓(xùn)練前后比較采用配對樣本T檢驗,組間差異采用獨立樣本T檢驗,P0.05為顯著性差異。研究結(jié)果顯示:(1)兩組訓(xùn)練前后體重并沒有顯著性變化,但兩組的Fat%出現(xiàn)了顯著的降低。(2)在肺功能方面,HIIT組的肺活量有顯著的提高,MCT組均沒顯著性變化。(3)在心臟形態(tài)指標(biāo)中,兩組都沒有出現(xiàn)顯著性變化,但在心臟功能上,HIIT運動所能達(dá)到的最大心率(HRmax),以及安靜狀態(tài)下的心率(Hr)、舒張壓(DP)、左心室舒張末期容量(EDV)、每搏輸出量(SV)都出現(xiàn)了顯著的改善,而MCT僅SV有所改善。(4)訓(xùn)練前后兩組的VO2max都有顯著提升,組間提升效果不存在差異。(5)在運動能力方面,HIIT組無氧閾出現(xiàn)時間延后、△乳酸量顯著上升、運動中的最大心率出現(xiàn)了顯著的提升,而MCT則無顯著變化。研究結(jié)論:HIIT與MCT均能顯著的提高VO2max,但在減少脂肪、改善肺功能、心功能及提高有氧運動能力上,HIIT具有更優(yōu)的訓(xùn)練效果。
[Abstract]:As a popular fitness method, (HIIT) with high intensity interval training has attracted wide attention from scholars at home and abroad, and compared with (MCT) in moderate intensity continuous training. The effects of two kinds of training methods on cardiopulmonary function and aerobic exercise ability have been disputed by many researchers. The purpose of this study was to compare the effects of two exercise styles on cardiopulmonary function and exercise ability by HIIT and MCT,. The subjects were 18 normal male college students (MVPA=43.36 鹵24.61 min / d, without systematic training), aged 21.65 鹵1.53 years, 179.30 鹵6.43 cm tall and 78.17 鹵12.64 kg. They were randomly divided into HIIT and MCT groups. The body fat rate (Fat%), pulmonary function and cardiac color ultrasound in quiet state, resting oxygen uptake and maximal oxygen uptake (GXT) were measured, respectively. The initial rate was 8 km / h, and the increase of 1 km / h per 3min velocity was 1 km/ h, respectively. When the speed exceeded 12km/h, the velocity of each stage remained unchanged, increasing the slope by 1% until the subjects could not persist), and blood lactic acid was measured at the end of each stage load. The maximal oxygen uptake (VO2max) data were obtained 3 times a week for 8 weeks. HIIT regimen: 90%VO2max training 3 mins, 25%VO2max interval 2 mins. Reciprocating 6 groups. MCT scheme: the same measurements were performed after 60%VO2max 30min.8 week training. All the results were expressed as mean 鹵standard deviation, compared before and after training with paired sample T test, and the difference between groups was independent sample T test, P0.05 was significant difference. The results showed that: (1) there was no significant change in body weight before and after training, but Fat% decreased significantly in both groups. (2) in terms of lung function, the vital capacity of HIIT group increased significantly. (3) there was no significant change in cardiac morphologic indexes in both groups, but in cardiac function, the maximum heart rate (HRmax), that HIIT could achieve and the heart rate (Hr), in quiet state were not significantly changed. Left ventricular end-diastolic volume (EDV),) output volume (SV) was significantly improved in diastolic blood pressure (DP), while MCT SV was only improved. (4) VO2max was significantly increased in both groups before and after training. (5) in the aspect of exercise ability, the time of anaerobic threshold in HIIT group was delayed, the amount of lactic acid increased significantly, the maximal heart rate in exercise increased significantly, but MCT did not change significantly. Conclusion: both HIIT and MCT can significantly improve VO2max, but HIIT has better training effect in reducing fat, improving lung function, heart function and aerobic exercise ability.
