【摘要】：目的:研究普通大學(xué)生采用不同形式的恢復(fù)手段進行干預(yù),分析運動后主動恢復(fù)、電刺激療法以及自然恢復(fù)的影響和效果,為普通人群消除運動性疲勞恢復(fù)提供方法和依據(jù)。方法:本研究采用自身對照實驗設(shè)計,將8名受試者分為對照組(CON)、神經(jīng)肌肉電刺激組(NMES)以及主動恢復(fù)組(ACT),分別進行遞增負荷力竭的功率自行車運動。為了誘導(dǎo)受試者產(chǎn)生運動性疲勞,每組實驗共進行三次自行車運動。第一次運動10min,選擇一種恢復(fù)方式恢復(fù)20min。第二次運動10min,同種方式恢復(fù)20min。第三次令受試者運動至力竭,記錄最后一次力竭時間作為重要觀察指標。在兩次恢復(fù)過程中主要測量心率、血乳酸、肌氧含量、心泵功能指標、主觀疲勞感覺(RPE)和主觀疼痛度等指標。結(jié)果:對照組、神經(jīng)肌肉電刺激組和主動恢復(fù)組力竭時間分別為624.14±125.38s、725.14±103.03s和749.00±102.20s,主動恢復(fù)組明顯長于對照組(P0.05);在第二次恢復(fù)第15min時,主動恢復(fù)組心率為74.88±8.04bpm低于對照組86.13±12.12bpm(P0.05);主動恢復(fù)組在第一次和第二次恢復(fù)第15min時血乳酸低于對照組均(P0.05);主動恢復(fù)組肌氧變化幅度高于對照組分別為40.88±6.85%和22.50±9.02%(P0.01),主動恢復(fù)組肌氧恢復(fù)效率高于對照組(P0.05);第一次恢復(fù)5min時主動恢復(fù)心輸出量(CO)高于對照組具有非常顯著性差異(P0.01),主動恢復(fù)組總外周阻力(TPR)低于對照組具有顯著性差異(P0.05),主動恢復(fù)組心指數(shù)(CI)與心功率指數(shù)(CPI)與對照組無明顯差異;主動恢復(fù)組運動后即刻的主觀疼痛感覺低于對照組(P0.05),24h后主觀疼痛感覺顯著低于對照組(P0.01);電刺激組與對照組各指標均無顯著性差異。。結(jié)論:主動恢復(fù)能夠增強運動能力,延長運動時間,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.
