中文摘要:
      目的:探讨上海游泳队优秀游泳运动员心脏形态及功能特点。方法:运用超声心动图技术分析32名优秀游泳运动员(男12人,女20人)和40名普通人(男20人,女20人)的心脏形态结构与功能。结果:优秀游泳运动员的主动脉根部内径(AoD)、左房前后径(LAAPD)、左室舒张末期前后径(LVEDD)、左室收缩末期前后径(LVESD)、左室舒张末期室间隔厚度(IVSd)、左室舒张末期后壁厚度(LVPWd)、左室心肌重量(LVM)、左室心肌质量指数(LVMI)均大于普通人群(P<0.05),差异有统计学意义,且左室舒张末容积(LVEDV)、左室收缩末容积(LVESV)均显著高于普通人群(P<0.05),左室射血分数(LVEF)及左室缩短分数(LVFS)低于普通人群,男子组有显著差异(P<0.05),而女子组无明显差异(P>0.05)。男女运动员左室每搏输出量(LVSV)均显著高于普通人群(P<0.05),而左室心输出量(LVCO)与普通人群无明显差异(P>0.05)。结论:上海优秀游泳运动员心脏发生耐力力量型生理性重塑,心脏泵血功能显著增强,具有较强的心力贮备,可作为优秀游泳运动员选拔的重要参考指标。
英文摘要:
      Objective: To assess the cardiac structure and function of elite swimmers in Shanghai Swimming Team. Subjects and methods: Echocardiography was used to study the cardiac structure and function of 32 elite swimmers (12 males and 20 females) and 40 ordinary people (20 males and 20 females). Results: The AOD, LAAPD, LVEDD, LVESD, IVSD, LVPWD, LVM, LVMI of elite swimmers were all better than the general population (P<0.05), the difference being statistically significant. The LVEDV and LVESV were significantly higher than the general population (P<0.05), while the LVEF and LVFS were lower than the general population. Moreover, there was significant difference in the male group (P<0.05), but not in the female group (P>0.05). The LVSV of both male and female athletes was significantly higher than that of the general population (P<0.05), while the LVCO was not significantly different from that of the general population (P>0.05). Conclusion: The hearts of the elite swimmers in Shanghai were physiologically remodeled with endurance and strength. Their cardiac function was significantly enhanced with a strong heart rate reserve. These indexes can be used to draft elite swimmers.
