中文摘要:

      目的 探讨服用茶叶碱对运动员的竞技技能和体能恢复效率的影响。方法 以36名运动员为实验对象, 将运动员平均分成3组, 每组运动员分别服用茶叶碱的剂量为高剂量、低剂量与安慰剂3个剂量, 测试内容包括基础指标测试、血液生理生化指标测试、有氧代谢测试和无氧能力测试, 并采用SPSS17.0统计分析软件对结果分析。结果 运动员总体重在服用不同剂量的茶叶碱后均表现出下降; 不同剂量组的干预方式对运动员基础指标并无显著影响(P>0.05)与服用前相比, 运动员血常规中红细胞计数(red blood cell count, RBC)和红细胞压积(hematocrit, HCT)有所降低, 但服用前后并无显著差异(P>0.05); 不同剂量组运动员在呼吸交换率、相对最大摄氧量、无氧阈心率、每分钟通气量的表现值均无显著性差异(P>0.05)各血乳酸值在组内与组间均无显著性差异(P>0.05); 运动员在服用不同剂量茶叶碱后其相对峰功率、相对平均功率和功率递减率均无显著性差异(P>0.05)。结论 服用茶叶碱对与运动身体的基础指标和血常规并无显著影响, 适当剂量的茶叶碱有利于体能指标恢复, 对运动员的有氧运动有帮助, 该研究有利于茶叶碱在营养保健品方面的推广。

英文摘要:

      Objective To analyze the effects of natural tea alkaloids on athletes' competitive skills and recovery efficiency. Methods 36 players as test object were divided into three groups, each group of athletes taking tea alkali dosage for high dose, low dose and placebo doses, respectively. The test content included basic index test, blood physiological and biochemical index test, aerobic metabolism test and anaerobic ability testing. SPSS17.0 statistical analysis softwarewas used to analysis the results. Results The overall weight of the athletes decreased after taking different doses of tea. Intervention methods in different dose groups had no significant effect on the basic indexes of athletes (P>0.05). Compared with before taking the medicine, red blood cell count (RBC) and hematocrit (HCT) in blood routine of athletes were reduced, but there was no significant difference before and after taking the medicine (P>0.05).There were no significant differences in the performance values of respiratory exchange rate, relative maximal oxygen uptake, anaerobic threshold heart rate, and ventilation per minute among athletes of different dose groups (P>0.05). There were no significant differences in the blood lactic acid values between and within the groups (P>0.05). There was no significant difference in relative peak power, relative average power and power decline rate of athletes after taking different doses of tea (P>0.05). Conclusion Taking theophylline has no significant effect on the basic indexes and blood routine of sports body. The appropriate dosage of theophylline is beneficial to the physical recovery and may be helpful to the aerobic exercise of athletes. This study is conducive to the promotion of theophylline in nutrition and health care products.
