体操运动员比赛时尿内儿茶酚胺的排出量

EXCRETION OF URINARY CATECHOLAMINE DURING COMPETITION IN GYMNASTS

测量了37名体操运动员在比赛前和训练前的血压和脉率,并测了25名运动员赛前、赛后和训练后尿内儿茶酚胺的排出量。结果发现男子组赛前舒张压比训练前为高。比赛后尿内去甲肾上腺素排出量男女组均显著高于比赛前,男子组训练后尿内去甲肾上腺素排出量比比赛后略低,而女子组则比比赛后有明显降低。说明男子组去甲肾上腺素的排出增加与情绪的关系较少,而女子组则与情绪关系较密切。赛后肾上腺素排出量男女组均有明显增加,训练后排出量均比比赛后排出量低。女子组在赛前、赛后、训练后肾上腺素排出量均比男子组为低,但差异未达显著水平。比赛中发挥好的肾上腺素排出量倾向较低。

Blood pressure and pulse rate of 37 gymnasts were measured in the precompetition and pretraining period, Excretion of urinary catecholamine of 25 gymnasts was determined in the precompetition period and during competition and training period.It was found that the diastolic blood pressure in the precompetition period was higher than that in pretraining period in male gymnasts. Excretion of noradrenaline (NA) during competition increased significantly both in male and female gymnasts. Compared with the competition period decrease of NA excretion was significant during training in the female group, however, no significant decrease was observed in the male group. Excretion of adrenaline (A) increased significantly during competition period both in the male and female group and decreased during training.Excretion of A was lower in these gymnasts whose performance was good. Excretion of NA also was lower only in the good performance group of females, but in the male group it was similar either in the good or bad performance group.
