【摘要】：目的:研究普通大學(xué)生采用不同形式的恢復(fù)手段進(jìn)行干預(yù),分析運(yùn)動(dòng)后主動(dòng)恢復(fù)、電刺激療法以及自然恢復(fù)的影響和效果,為普通人群消除運(yùn)動(dòng)性疲勞恢復(fù)提供方法和依據(jù)。方法:本研究采用自身對(duì)照實(shí)驗(yàn)設(shè)計(jì),將8名受試者分為對(duì)照組(CON)、神經(jīng)肌肉電刺激組(NMES)以及主動(dòng)恢復(fù)組(ACT),分別進(jìn)行遞增負(fù)荷力竭的功率自行車(chē)運(yùn)動(dòng)。為了誘導(dǎo)受試者產(chǎn)生運(yùn)動(dòng)性疲勞,每組實(shí)驗(yàn)共進(jìn)行三次自行車(chē)運(yùn)動(dòng)。第一次運(yùn)動(dòng)10min,選擇一種恢復(fù)方式恢復(fù)20min。第二次運(yùn)動(dòng)10min,同種方式恢復(fù)20min。第三次令受試者運(yùn)動(dòng)至力竭,記錄最后一次力竭時(shí)間作為重要觀察指標(biāo)。在兩次恢復(fù)過(guò)程中主要測(cè)量心率、血乳酸、肌氧含量、心泵功能指標(biāo)、主觀疲勞感覺(jué)(RPE)和主觀疼痛度等指標(biāo)。結(jié)果:對(duì)照組、神經(jīng)肌肉電刺激組和主動(dòng)恢復(fù)組力竭時(shí)間分別為624.14±125.38s、725.14±103.03s和749.00±102.20s,主動(dòng)恢復(fù)組明顯長(zhǎng)于對(duì)照組(P0.05);在第二次恢復(fù)第15min時(shí),主動(dòng)恢復(fù)組心率為74.88±8.04bpm低于對(duì)照組86.13±12.12bpm(P0.05);主動(dòng)恢復(fù)組在第一次和第二次恢復(fù)第15min時(shí)血乳酸低于對(duì)照組均(P0.05);主動(dòng)恢復(fù)組肌氧變化幅度高于對(duì)照組分別為40.88±6.85%和22.50±9.02%(P0.01),主動(dòng)恢復(fù)組肌氧恢復(fù)效率高于對(duì)照組(P0.05);第一次恢復(fù)5min時(shí)主動(dòng)恢復(fù)心輸出量(CO)高于對(duì)照組具有非常顯著性差異(P0.01),主動(dòng)恢復(fù)組總外周阻力(TPR)低于對(duì)照組具有顯著性差異(P0.05),主動(dòng)恢復(fù)組心指數(shù)(CI)與心功率指數(shù)(CPI)與對(duì)照組無(wú)明顯差異;主動(dòng)恢復(fù)組運(yùn)動(dòng)后即刻的主觀疼痛感覺(jué)低于對(duì)照組(P0.05),24h后主觀疼痛感覺(jué)顯著低于對(duì)照組(P0.01);電刺激組與對(duì)照組各指標(biāo)均無(wú)顯著性差異。。結(jié)論:主動(dòng)恢復(fù)能夠增強(qiáng)運(yùn)動(dòng)能力,延長(zhǎng)運(yùn)動(dòng)時(shí)間,降低心率,加快清除血液中堆積的乳酸和代謝產(chǎn)物,加快肌氧的恢復(fù)效率。電刺激組在恢復(fù)疲勞方面沒(méi)有效果。
[Abstract]:Objective: to study the effects and effects of active recovery, electrical stimulation therapy and natural recovery in general college students with different forms of rehabilitation, so as to provide methods and basis for the general population to eliminate exercise fatigue recovery. Methods: eight subjects were divided into (CON), neuromuscular stimulation group (NMES) and active recovery group (ACT),). In order to induce exercise-induced fatigue, each group underwent three cycling exercises. After the first exercise for 10 min, choose a recovery method for 20 min. The second exercise lasted 10 minutes and recovered 20 minutes in the same way. The last exhaustion time was recorded as an important observation index. Heart rate, blood lactic acid, muscle oxygen content, cardiac pump function, subjective fatigue sensation (RPE) and subjective pain degree were measured during two recoveries. Results: the exhaustion time of the control group, neuromuscular electrical stimulation group and active recovery group were 624.14 鹵125.38s (725.14 鹵103.03s) and 749.00 鹵102.20s, respectively. The active recovery group was significantly longer than the control group (P0.05). The heart rate of the active recovery group was 74.88 鹵8.04bpm lower than that of the control group 86.13 鹵12.12bpm (P0.05), the blood lactic acid of the active recovery group was lower than that of the control group at the first and the second 15min recovery (P0.05), and the change of muscle oxygen in the active recovery group was higher than that in the control group (40.88 鹵6.85% and 22.50 鹵9.02%, respectively, P 0.05), and that in the active recovery group was 22.50 鹵9.02% (P0.01). The recovery efficiency of muscle oxygen was higher than that of the control group (P0.05), and the (CO) of the first recovery of 5min was significantly higher than that of the control group (P0.01). The total peripheral resistance (TPR) of the active recovery group was significantly lower than that of the control group (P0.05). There was no significant difference in cardiac index (CI) and cardiac power index (CPI) between complex group and control group. The subjective pain sensation in the active recovery group was significantly lower than that in the control group (P0.05) 24 hours after exercise (P0.01); there was no significant difference between the electrical stimulation group and the control group. Conclusion: active recovery can enhance exercise ability, prolong exercise time, decrease heart rate, speed up the removal of lactic acid and metabolites accumulated in blood, and accelerate the recovery efficiency of muscle oxygen. The electrical stimulation group had no effect on recovery of fatigue.
