摘要
背景/目的运动后冷却对恢复的影响在经验文献中得到了很多关注,然而,关于在同一天内快速连续重复的跆拳道比赛中优化恢复的数据有限。因此,本研究的目的是比较模拟跆拳道战斗后外部和内部冷却对肠道温度(Tint),精神运动技能(反应时间,反应时间,运动时间)和神经肌肉功能(峰值扭矩,平均功率,达到峰值扭矩时间)的影响。方法采用随机平衡交叉设计,10名训练有素的男子跆拳道运动员在不同的情况下完成4种恢复方法:被动恢复(CON)、5分钟热中性水浸泡(35°C) (TWI)、5分钟冷水浸泡(15°C) (CWI)和冰浆摄入(-1°C) (ice;每5分钟消耗一次,持续30分钟)。心率(HR)、血乳酸(Blac)浓度和Tint分别在休息、战斗结束后和90分钟恢复期的选定时间间隔进行测定。在基线和恢复期后评估神经肌肉功能(用等速测功机测量)和精神运动指数。结果在模拟战斗后30 min (P<0.01)和45 min (P<0.01), ice导致色度显著降低;停服冰浆后15-30 min,分别与CON和TWI条件比较。然而,在其他情况下,Tint在不同时间点上没有差异(P>0.05)。90 min恢复期后,精神运动技能和神经肌肉功能指数恢复到基线值(P>0.05),两组间无差异(P>0.05)。结论内部(ICE)和外部(CWI)恢复方法在影响跆拳道重复格斗表现所需的时间过程中对生理和功能指标的影响不大。
Practical internal and external cooling methods do not influence rapid recovery from simulated taekwondo performance
Background/Objectives
The influence of post-exercise cooling on recovery has gained much attention in the empirical literature, however, data is limited in regards to optimizing recovery from taekwondo performance when combat is repeated in quick succession within the same day. The aim of this study was therefore to compare the effects of external and internal cooling after simulated taekwondo combat upon intestinal temperature (Tint), psychomotor skills (reaction time, response time, movement time), and neuromuscular function (peak torque, average power, time to reach peak torque).
Methods
Using a randomized counterbalanced crossover design, 10 well-trained male taekwondo athletes completed four recovery methods on separate occasions: passive recovery (CON), a 5-minute thermoneutral water immersion (35°C) (TWI), a 5-min cold water immersion (15°C) (CWI), and ice slurry ingestion (-1°C) (ICE; consumed every 5 min for 30 min). Heart rate (HR), blood lactate (Blac) concentrations, and Tint were determined at rest, immediately after combat, and at selected intervals during a 90-min recovery period. Neuromuscular functional (measured with isokinetic dynamometer) and psychomotor indices were assessed at baseline and after the recovery period.
Results
ICE led to a significantly lower Tint at 30 min (P<0.01) and 45 min (P<0.01) after simulated combat; 15-30 min after cessation of ingesting ice slurry, compared with the CON and TWI conditions, respectively. However, there were no differences in Tint across time points between the other conditions (P>0.05). Psychomotor skills and neuromuscular function indices returned to baseline values after the 90 min recovery period (P>0.05) with no differences observed between conditions (P>0.05).
Conclusion
The present findings suggest that internal (ICE) and external (CWI) recovery methods appear to have little impact on physiological and functional indices over the time course required to influence repeated taekwondo combat performance.
