摘　　要：目的探讨西藏昌都和日喀则两地儿童运动前后心功能变化。方法以西藏自治区昌都和日喀则两地11～12岁的130名儿童为研究对象，通过递增负荷自行车测试，观察运动前后两地儿童超声心动图变化。结果运动前后昌都芒康县男女生的左心室射血分数，左心室舒张末期内径，左心室收缩末期内径，左心室质量，每搏输出量，心排出量等心脏功能变量值均高于日喀则白朗县儿童。结论初步结果证明西藏东部昌都地区儿童的心脏功能和运动能力强于西部后藏地区儿童的运动能力。Objective To explore the echocardiography changes of Tibetan children before and after exercise at the Qamdo and shigatse area in the Tibet Autonomous Region. Methods 130 Tibetan children of 11 - 12 years old were selected randomly from Qamdo Markam county and Shigatse Brown county, respectively. Eehoeardiograhy changes before and after exercise were detected through incre- mental cycling test（Monark Erogmedic 839, varberg）. Results Cardiac function variable values of both boys and girls before and after exercise in Qamdo Marka couty were all higher than those of children in Shigatse Brown county, such as ejection fraction（EF） , left ven- tricular end - diastolic dimension （LVEDD） , left ventrieular end - systolic dimension （LVESD） , left ventrieular mass （ LVM ）, stroke vol- ume（SV） , and cardiac output（CO） and so on. Conclusion Prilimary data showed that cardiac function and the motor capacity of Tibetan children in Qamdo area were stronger than those Tibetan children in Shigates area in the Tibet Autonomous Region.
