Echocardiografic data before and after exercise training.

HR, heart rate; LVDD and LVSD, LV diastolic and systolic diameters, respectively; PWT, LV posterior wall thickness; RWT, LV relative wall thickness in diastole; LA, left atrium diameter; AO, aortic diameter; FS, LV endocardial fractional shortening; PWSV, LV posterior wall shortening velocity; E/A, early-to-late diastolic mitral inflow ratio; EF, ejection fraction. n = 8 per group. Data are expressed as mean ± SD.
*p<0.05 vs. Sham-UN and,
#p<0.05 vs. Sham-ET at the same time (18 wk or 28 wk);
†p<0.05 vs. AS-UN;
‡p<0.05 vs. AS; t test, one-way or 2-way ANOVA with Bonferroni post hoc test as appropriate.
Echocardiografic data before and after exercise training.

HR（heart rate）即心率；LVDD与LVSD分别指左心室舒张末期内径（LV diastolic diameter）与左心室收缩末期内径（LV systolic diameters）；PWT为左心室后壁厚度（LV posterior wall thickness）；RWT为舒张期左心室相对室壁厚度（LV relative wall thickness in diastole）；LA为左心房内径（left atrium diameter）；AO为主动脉内径（aortic diameter）；FS为左心室心内膜短轴缩短率（LV endocardial fractional shortening）；PWSV为左心室后壁缩短速率（LV posterior wall shortening velocity）；E/A为二尖瓣舒张早期与晚期血流充盈比值（early-to-late diastolic mitral inflow ratio）；EF为射血分数（ejection fraction）。每组样本量为n=8，数据以平均值±标准差（mean ± SD）表示。
*p<0.05 相较于Sham-UN组；
#p<0.05 相较于同一时间点（18周或28周）的Sham-ET组；
†p<0.05 相较于AS-UN组；
‡p<0.05 相较于AS组；统计检验采用t检验、单因素方差分析或双因素方差分析，并根据实际情况辅以Bonferroni事后检验。
本数据集包含运动训练前后的超声心动图（Echocardiografic）相关数据。
