摘要
为探讨不同强度全身振动训练对于生物体运动表现、运动疲劳以及生理生化反应的影响。本研究使用4周大雄性C57BL/6J小鼠为模型,随机分作3组,每组8只动物:无振动训练对照组(sedentary control,SC);相对较低强度振动训练组(5.6 Hz/0.13 g; relative low-intensity vibration, LV);相对较高强度振动训练组(13 Hz/0.68 g; relative high-intensity vibration, HV)。振动训练以每天振动15 min,每周5次,为期4周,随后进行各项测试包括:前肢抓力、衰竭性耐力运动测验、疲劳生化指标分析、临床血液生化检测以及病理组织切片观察。数据以单因素方差进行分析,并以Duncan's test检验不同的组间是否存在显著差异。两组接受振动训练介入的小鼠比对照组,具有显著提升肌力和衰竭性耐力运动的时间。在疲劳与肌肉损伤相关生化指标部分,振动训练具有明显降低单次运动测试后血氨与血乳酸浓度以及肌酸激酶活性上升的作用。在临床血液生化方面,4周振动训练显著降低草醋酸转胺酶、麸丙酮酸转胺酶与肌酸激酶活性,以及尿素氮浓度。本研究证实振动训练4周的连续介入下,具有提升运动表现与抗疲劳的作用,而且不会造成健康小鼠在生理生化以及病理上的副作用。在提供一般健康成人的运动训练指导上,全身振动训练具有健康促进的应用性。
In order to investigate the effects of whole-body vibration training of different intensities on exercise performance, exercise fatigue and physiological and biochemical responses of organisms, in this study, 4-week-old male C57 BL/6 J mice were randomly divided into 3 groups with 8 animals in each group:(i) sedentary control(SC),(ii) WBV at relative low-intensity(5.6 Hz, 0.13 g)(VL), or(iii) relative high-intensity(13 Hz, 0.68 g) WBV(VH).Animals of two vibration groups were subjected to vibration stimulus 15 min/day, 5 days/week for 4 weeks. The tests were then carried out, including forelimb grip strength, exhaustion endurance exercise test, fatigue biochemical index analysis, clinical blood biochemistry test and pathological tissue slice observation. The data were analyzed by one-way analysis of variance(ANOVA) and statistical differences among groups were analyzed by Duncan’s test. The results indicated that two WBV groups(the LV and HV groups) showed increased grip strength and exhaustive endurance time as compared to the SC group. For biochemical indexes related to fatigue and muscle injury, vibration training could obviously decrease the concentration of blood ammonia and blood lactic acid and increase the activity of creatine kinase after a single exercise test. In clinical blood biochemistry,four-week vibration training could significantly reduce the activities of acetic acid transaminase, gluten pyruvate transferase and creatine kinase, as well as the concentration of urea nitrogen. The results of the current study suggested that the contin uous intervention of vibration training for four weeks could improve exercise performance, anti-fatigue capacity, and would not cause physiological, biochemical and pathological adverse side effects in health mice. In providing sports training guidance for general healthy adults, the whole body vibration training has application value for the health promotion.
