摘要
目的:比较电针刺激足三里与聆听放松音乐疗法对急性有氧运动疲劳的恢复效果。方法:实验于2004-10/2005-01选取南京体育学院48名健康男大学生志愿者,随机分为自然恢复组、音乐治疗组、低频电针组,16名/组。①以80%～85%的乳酸阈强度即65W为初始功率,受试者进行1min的准备活动后,正式开始有氧运动直至疲劳。判断疲劳的标准为自我感觉疲劳、且一再鼓励后仍不能维持预定的运动强度。②一次性有氧运动至疲劳后,音乐治疗组卧位,戴耳机听放松音乐,音量以感觉舒适为度,一般控制在45.0～63.5dB。低频电针组卧位,双足三里针刺得气后,以1Hz的低频脉冲给予电刺激。自然恢复组静卧休息,不给予任何治疗。各组治疗时间均持续15min。③比较各组治疗前后心率、下肢肌力、下肢围度、血糖、尿蛋白、血乳酸、视觉简单反应时、主观体力感觉等生理、生化及心理指标的变化。结果:按意向处理分析,实验纳入健康男大学生志愿者48名,全部进入结果分析。①运动前、运动后即刻各项指标的组间比较:经统计学检验,各组间心率、大腿围、小腿围、下肢肌力、简单反应时、主观体力感觉值、血乳酸、血糖及尿蛋白等指标在运动前、运动后即刻均基本相似(P>0.05)。②运动前后各项指标的配对检验结果:与运动前比较,运动后即刻心率、大腿围、小腿围、主观体力感觉值均显著增加(P<0.01);血糖及尿蛋白均显著下降(P<0.01,P<0.05);简单反应时及血乳酸无明显变化(P>0.05)。运动后10min心率平均值为(81.82±10.29)次/min,与运动后即刻心率相比显著降低(P<0.01),而与运动前相比显著升高(P<0.01)。③受试者运动后即刻自觉症状统计结果:48名受试者中,汗多者占75.00%,口干者占54.17%,下肢乏力者占52.08%,脚跟发软及下肢酸痛、僵硬者分别占16.67%和14.58%。④治疗后各项指标的组间比较:音乐治疗组尿蛋白显著低于自然恢复组和低频电针组(P<0.01,P<0.05),其余各项指标各组间均无显著性差异(P>0.05)。⑤各组运动后即刻与干预治疗后各项指标的配对检验结果:与运动后即刻比较,治疗后15min音乐治疗组心率、大腿围、小腿围、主观体力感觉值、尿蛋白均显著降低(P<0.05或P<0.01),低频电针组心率、大腿围、小腿围、主观体力感觉值、乳酸均显著降低(P<0.05或P<0.01)。结论:低频电针足三里对消除心血管疲劳及清除乳酸的效果较佳,而音乐疗法依从性强、操作简单,具有较好的促进中枢、骨骼肌及心理疲劳恢复、增强肾脏调节能力的作用。
AIM： To compare recuperative effects of musicotherapy and low-frequency electro-acupuncture （EA） at zusanli on acute aerobic exercise-induced fatigue.
METHODS： A total of 48 healthy male undergraduates in Nanjing Institute of Physicial Education from October 2004 to January 2005 were selected in the experiment and randomly divided into spontaneous recovery group, musicotherapy group and low-frequency EA group with 16 ones in each group. ① The initial exercise intensity were 80%-85% of lactic acid threshold, i.e. 65 Watts. After 1-minute warm-up, subjects kept on doing aerobic exercise until fatigued. Judging standard of fatigue were that felt fatigue and could not maintain presumptive exercise intensity even with much encouragements.②After once aerobic exercise, subjecis in the mnsicotherapy group lied down and listened to the music with headphones in proper volume, which was usually between 45-63.5 decibels. Subjects in the Low-frequeney EA group received acupuncture on zusanli （ST36） and then were given of low-density electric stimulation at 1 Hz. Subjects in the spontaneous recovery group lied down for rest without any other treatment. Time of therapy in each group was 15 minutes. ③Changes of heart rates, perimeter and muscular energy of lower extremities, blood glucose, urine protein, blood lactic acid, simple reaction time, ratings of perceived exertion （RPE） and mental indexes etc. before and after the treatment among groups were compared.
RESUTLS： AcCording to intention-to-treatment analysis, 48 included healthy male undergraduates were involved in the analysis of results. ① Comparison of each indexes immediately before and after exercise among groups： After statistically tested, indexes such as heart rate, thigh girth,shank girth, muscular energy of lower extremities, RPE, simple reaction time blood lactic acid, blood glucose and uric protein among each group immediatedly before and after exercise were fundamentally similar （P 〉 0.05）. ② Results of paired test： Compared with those before exercise, heart rates, thigh girth, shank girth and RPE immediately after exercise were significandy increased （P〈 0.01）; Blood glucose and uric protein decreased obviously （P 〈 0.01, P 〈 0.05）; There were no significant differences in simple reaction time and blood lactic acid （P 〈 0.05）. The average value of heart rate 10 minutes after the exercise was （81.82±10.29） beats/rain, which was significantly lower than that at immediate postexereise （P 〈 0.01） and was significantly higher than that before exercise （P 〈 0.01）. ③Statistical resuits of subjective symptomes： Among 48 testees, 75.00% subjects sweated much, 54.17% subjects got dry mouth, 52.08% subjects felt debility in lower limbs, subjects with heels became limp and aching pain in lower limbs and stiffness respectively accounted for 16.6/% and 14.58%. ④ Comparison of each indexes among groups after therapy： Uric protein of the musicotherapy group was obviously lower than that of spontaneous recovery group and low-frequency EA group （P 〈 0.01, P 〈 0.05）, while there were no significant differences in other indexes among groups （P 〉 0.05）. ⑤Resuits of paired test of each indexes among groups immediately after exercise and after intervention： Compared with those after immediate pestexercise, heart rate, thigh girth, shank girth, RPE and urine protein of musicotherapy group were decreased significantly （P 〈 0.05 or P 〈 0.01）, while heart rate, thigh girth, shank girth, RPE and lactic acid of low-frequency EA group were obviously reduced （P 〈 0.05 or P 〈 0.01）.
CONCLUSION： Curative effect of low-frequency EA at zusanli is excellent in eliminating cardiovascular fatigue and lactic acid, while musicotherapy has good compliance and is simple in operating, which has good effects in promoting the recovery of cefitral fatigue, museuli skeleti fatigue and psychological fatigue as well as reinforcing the regnlatory capebility of kidney.
