摘要
目的:研究射击运动员赛前焦虑和尿儿茶酚胺水平的变化,探寻判断运动员赛前焦虑的方法。方法:利用高效液相色谱分析技术,分别测定20名上海市射击运动员在一场国内比赛前4周(T1)、2周(T2)和1周(T3)时晨尿肾上腺素、去甲肾上腺素和多巴胺的水平,采用运动竞赛状态焦虑量表,测量并结合认知状态焦虑(S1)、躯体状态焦虑(S2)和状态自信心(S3)得分,进行统计分析,寻找反映赛前焦虑的特征性指标。结果:运动员尿肾上腺素和多巴胺排出量T2时段较T1时段、T3时段较T2时段均显著升高(P<0.05),运动竞赛状态焦虑量表S1和S2得分T2时段较T1时段、T3时段较T2时段均显著升高(P<0.05),而T3时段S3得分较T2时段无明显变化。T1、T2、T3时段认知状态焦虑得分和肾上腺素的相关系数分别为0.80、0.65和0.73(P<0.05),躯体状态焦虑得分和肾上腺素相关系数分别为0.69、0.77和0.62(P<0.05),躯体状态焦虑得分和多巴胺的相关系数分别为0.61、0.42和0.46(P<0.05)。结论:尿肾上腺素和多巴胺水平与赛前焦虑相关,结合运动竞赛焦虑状态量表得分,可用于判断运动员赛前焦虑状态。
Objective To study the relation of urinary catecholamine level to the precompetitive anxiety state in shooters.Methods Morning urinary adrenaline,noradrenaline and dopamine levels were determined with high-performance liquid chromatography in 20 shooters 4 weeks（T1）,2 weeks（T2） and 1 week（T3） before a domestic competition.According to the CSAI-2,scores of cognitive state anxiety（S1）,somatic state anxiety（S2） and the state of self-confidence（S3） were obtained.Results The urinary excretions of adrenaline and dopamine in T2 and T3 increased respectively as compared with that in T1 and T2（P 0.05）;and the scores of S1 and S2 in T1 and T2 were respectively higher than that in T2 and T3（P 0.05）,while S3 remained unchanged.The correlation coefficients between S1 and adrenaline,S2 and adrenaline,and S2 and dopamine in T1,T2 and T3 were 0.80,0.65 and 0.73（P 0.05）,0.69,0.77 and 0.62（P 0.05）,and 0.61,0.42 and 0.46（P 0.05）,respectively.Conclusion Urinary epinephrine and dopamine levels highly correlate to the precompetitive anxiety state in shooters,and thus can be used for determining the state of anxiety before competition.
