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

[目的]采用双盲随机对照试验，探讨按压针刺对中长跑运动员训练营训练疲劳的影响。[方法]受试者为某高校田径俱乐部中长跑运动员，同意参加试验。实验一：将受试者随机分为真针刺组(n=16)和安慰剂针刺组(n=16)。实验二：真针刺组(n=13)与非针刺组(n=14)进行对照试验。分别在双侧双腿和腰背部皮肤的10个中医穴位上贴压针刺(Ponex、Seirin)或安慰剂针刺，测定主观疲劳程度、训练情况、肌肉僵硬程度、站立位身体屈曲、POMS、肌酸激酶等生理生化指标，第8天每天早晚各2次。[结果]1.随着夏令营日程的推进，主观疲劳感逐渐增强。真正针刺组的主观疲劳程度低于非针刺组。在真实组和安慰剂组之间没有显著差异。2.在训练条件的时程变化和身体屈曲方面，两组间无显著差异。3.肌酸激酶在第7天的活性高于开始的第1天。4.从夏令营后的调查结果来看，真正针刺组的疗效优于安慰剂组。

[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.
