| 摘 要： | 在低海拔地区运动员 ( 6男 2女 )急进高原参加为期 9天的多巴 ( 2 3 66m)～拉萨 ( 3 780m)青藏高原自行车拉力赛期间 ,对赛前 (多巴 ,2 3 66m)、赛中 (格尔木 ,2 80 7m)、赛后 (拉萨 ,3 780m)安静状态下的心脏功能进行了测试。结果表明 ,Pd、V以及TPR有所升高 ,HR、SV、CO、SI以及CI持续下降 ,赛后与赛前相比除HR、V无显著差异外 ,Pd、SV、CO、SI、TPR (P <0 0 1)以及CI (P <0 0 5 )差异显著。认为心脏功能的降低 ,主要受体内水分的下降 ,血浆和血的容量大量减少 ,血粘度升高 ,外周阻力增大 ,有效循环血量不足所致。建议低海拔地区运动员参加青藏高原自行车拉力赛 ,应至少提前 1周进入高原 ( 2 3 66m)进行适应性训练 ,以便减轻心脏负荷 ,改善心肺循环功能。

| Abstract: | The cyclists (six male, two female) who from lower elevation area to high plateau to took part in cycle racing which lasted nine days from Duoba(2366m)to Lasa(3780m) on Qinghai-Tibet plateau, during the competition, a series of tests such as Pd, SV, CO, CI, SI, HR, V, TPR and so on were made The results showed that there were obviously many difference before and after the racing, it directly influences on competition's result The paper suggest that the cyclists whom from lower elevation area to high plateau should be carried out an adaptability training at least one week before racing, so as to lighten the burden of heart and improve circulatory function of lung and heart |
