项目摘要

The purpose of this study was to investigate the influence of rapid cooling of muscles (icing) after every training session on adaptive changes from the endurance training (Series-E in 2001) and resistance training (Series-R in 2002). Six male volunteers participated in the Series-E project that consisted of 25-minutes of bicycle exercise at a workload of 70% Vo_2max four times a week for four weeks. During this training period, unilateral leg of the subjects was immersed twice in cold water (5±1℃) for 20-minutes for intervals of 20-minutes after every training session. Before and after the training period, and incremental cycle ergometer test for exhaustion was performed with each leg to determine one-legged maximal work capacity and oxygen consumption (VO_2peak). Seven males and four females volunteers participated in the Series-R project that consisted of three sets of 8 bilateral handgrip exercises at a workload of 8 RM three times a week for 4 weeks. The unilateral forearm of the … More subjects was immersed in cold water (10±1℃) for 20-minutes after every training session. Before and after the training period, maximum strength and local muscular endurance were measured. In the Series-E project, the mean performance time of an incremental cycle ergometer test significantly (p<0.05) increased for the control side after the training, while the mean performance time of the icing side did not increase. The rate of increase in one-legged VO_2peak of the icing side was significantly smaller than that of the control side. In the Series-R project, maximum strength significantly increased for both sides that is a p<0.05 for the icing side and p<0.01 for the control side. The local muscular endurance estimated by the number of repetition to reach exhaustion in the control side significantly (p<0.01) increased, while that in icing side failed to change. These results suggest that during a period of training, adaptive changes in endurance capacity in response to both endurance and resistance training might be decreased by the application of icing. Further studies are needed for accumulation of physiological knowledge to ascertain the suitability of using sports icing. Less

本研究旨在探讨肌肉快速降温对耐力训练(2001年E系列)和阻力训练(R系列2002)适应性变化的影响。6名男性志愿者参加了E系列项目，该项目包括在70%Vo_2max负荷下进行25分钟的自行车锻炼，每周4次，持续4周。在此训练期间，受试者的单侧腿在每次训练后被试在冷水(5±1℃)中浸泡2次，每次20分钟，间隔20分钟。训练前后分别对每条腿进行递增负荷力竭试验，测定单腿最大工作能力和最大耗氧量(VO2峰值)。7名男性和4名女性志愿者参加了R系列项目，该项目包括三套8个双侧握力练习，工作量为8马币，每周3次，为期4周。…的单侧前臂每次训练结束后，更多的受试者在冷水(10±1℃)中浸泡20min。训练前后分别测定最大力量和局部肌肉耐力。在E系列项目中，对照侧的增量循环功率机测试的平均表现时间在训练后显著增加(p&lt；0.05)，而结冰侧的平均表现时间没有增加。结冰侧单肢VO2峰值的增加幅度明显小于对照侧。在R系列项目中，两边的最大强度都显著增加，结冰侧为p&lt；0.05，对照侧为p&lt；0.01。以重复次数估计的局部肌肉耐力在对照侧显著增加(p&lt；0.01)，而在冰侧则无变化。这些结果表明，在训练期间，冰块的应用可能会降低耐力和耐力训练的耐力适应性变化。生理知识的积累还需要进一步的研究，以确定使用运动冰的适宜性。较少
