Has acupuncture therapy effectiveness on physical conditioning in long-distance runner ?

[目的]采用随机双盲对照试验（RCT）研究针刺压针对中长跑运动员集训期疲劳的影响。[方法]以某高校田径运动俱乐部中长跑运动员为研究对象，随机分为真实的针刺组（n=16）和安慰剂针刺组（n=16）。将真实的针刺组（n=13）与非治疗组（n=14）进行对照试验。按压针灸针（Pyonex，Seirin）或安慰剂针灸与双侧下肢和下背部皮肤的10个传统中国穴位相连。身体和生化检查，如主观疲劳程度、训练情况、肌肉僵硬度、站立位身体屈曲度，第8天每天早晚各测POMS和肌酸激酶。调查是关于针灸的反应，以及他们在夏令营结束后使用了哪种类型的针灸。[结果] 1.主观疲劳增加与营地的进度。真实的针刺组主观疲劳程度明显低于非治疗组。真实的和安慰剂组之间没有显著差异。2.各组间训练条件的时程变化和身体屈曲度无显著差异。3.肌酸激酶在第7天高于第1天。4.从夏令营后的调查结果来看，真实的针灸组比安慰剂组更有效。

[Objective] Double blind randomized control trial (RCT) was performed to clarify the effect of acupuncture using press needle on fatigue caused by the training in middle or long-distance runners during a training camp.[Methods] Subjects were middle or long-distance runners belonging to a track-and-field sports club in university, and agreed to participate in the trial.Experiment 1 : Subjects were randomly assigned to two groups, which were real acupuncture group (n=16) and placebo acupuncture group (n=16).Experiment 2 : The comparative trial was performed between real acupuncture group (n=13) and non-treatment group (n=14). Press acupuncture needle (Pyonex, Seirin) or placebo acupuncture were attached with the 10 traditional Chinese acupoints in bilateral lower limbs and the low back skin.Measurements : Physical and biochemical examination such as the level of subjective fatigue, the condition of training, the muscle stiffness, the body flexion in standing position, POMS and creatine kinase were evaluated two times at every morning and evening during the 8th day. The investigation was performed regarding the response to acupuncture and which type of acupuncture they had using questionnaires after the camp.[Results] 1. Subjective fatigue increased associated with progress of the schedule in the camp. The real acupuncture group showed less subjective fatigue than non-treatment group. No significant difference between the real and placebo group was obtained. 2. No significant difference in time course change of the training conditions as well as the body flexion was obtained among the groups. 3. Creatine kinase showed higher value in the seventh day than that of the initial day. 4. The real acupuncture group demonstrated more effective than the placebo group from the results of the investigation after the camp.
