碳酸氢钠对提高运动员竞技表现水平和缓解运动疲劳有较好效果，但运动员口服碳酸氢钠会有碱中毒、肠胃反应、心律失常等副作用，从而无法在竞技体育中广泛应用。目的：研究碳酸氢钠经皮肤外涂给药对男子足球运动员的高强度间歇训练期间血清指标和延迟性肌肉酸痛的影响。方 法：选取16名高水平男子足球运动员为研究对象，每天为其分别涂抹碳酸氢钠外用乳剂和安慰剂乳剂后，分别在7天高强度间歇训练后对训练后的主观疲劳程度和下肢延迟性肌肉酸痛程度进行统计，对训练前后血乳酸、肌酸激酶、尿素氮、血红蛋白等血液生化指标、训练期的训练刺激量、最大心率、能量消耗、有氧和无氧训练效果指标，跑动距离、跑动速度、加速度、高速跑距离、总负荷等运动表现指标进行分析。结 果：在一次高强度间歇训练前后，实验组相比对照组，血乳酸升高数值显著降低（p< 0.05），肌酸激酶升高数值增高，血尿素氮升高幅度降低；在7天训练期，相比于对照组，实验组的下肢DOMS和RPE总体水平显著降低（p< 0.05），下肢DOMS数值在第2天和第6天显著下降（p< 0.05）；在反映训练强度和训练效果的TRIMP数值上，实验组的总体水平高于对照组，且变化幅度更小。实验组运动员训练的无氧训练效果、EPOC峰值、最大心率、能量消耗相比于对照组均有所提升，其中最大心率、无氧训练效果有显著性提升（p< 0.05）。结 论：碳酸氢钠的外涂给药可以显著降低足球运动员高强度间歇训练带来的肌肉延迟性酸痛，并显著降低高强度训练产生的血液血乳酸浓度升高，有利于高强度训练后的无氧训练效果提升，使得运动员心率储备能力和快速恢复能力的增强，从而促进专项运动能力的提升。
Sodium bicarbonate is effective in improving athletic performance and relieving athletic fatigue, but oral administration of sodium bicarbonate to athletes is associated with side effects such as alkalosis, gastrointestinal reactions, and cardiac arrhythmias, thus preventing its widespread use in competitive sports. Objective: To investigate the effects of topical transdermal administration of sodium bicarbonate on serum indices and delayed muscle soreness during high-intensity interval training in male soccer players. Methods: Sixteen high-level male soccer players were selected for the study, and after applying sodium bicarbonate topical emulsion and placebo emulsion to them daily, respectively, after 7 days of high-intensity interval training, the subjective fatigue and delayed muscle soreness of lower limbs after training were counted, and the blood biochemical indices such as blood lactate, creatine kinase, urea nitrogen and hemoglobin before and after training, the amount of training stimulus during the training period, the maximum heart rate, energy expenditure, aerobic and anaerobic training effect indexes, running distance, running speed, acceleration, high speed running distance, total load and other sports performance indexes were analyzed. Results: Before and after a high-intensity interval training, the experimental group showed significantly lower blood lactate elevation (p< 0.05), higher creatine kinase elevation and lower blood urea nitrogen elevation compared to the control group; during the 7-day training period, the overall lower extremity DOMS and RPE levels were significantly lower in the experimental group compared to the control group (p< 0.05), and the lower extremity DOMS values were significantly The overall level of lower limb DOMS and RPE in the experimental group was significantly lower than that in the control group (p< 0.05), and the lower limb DOMS values were significantly lower on day 2 and day 6 (p< 0.05). The anaerobic training effect, peak EPOC, maximum heart rate, and energy expenditure of the experimental group athletes training were all improved compared with the control group, among which maximum heart rate and anaerobic training effect were significantly improved (p< 0.05) Conclusion: The topical administration of sodium bicarbonate can significantly reduce the delayed muscle soreness brought about by high-intensity interval training of soccer players, and significantly reduce the blood lactic acid produced by high-intensity training It is conducive to the enhancement of anaerobic training effect after high-intensity training, resulting in the enhancement of athletes"" heart rate reserve capacity and rapid recovery capacity, thus promoting the improvement of special athletic ability.
