Some individuals who go to fitness centers for various purposes perform resistance exercise (RE) alone, while others engage in combined exercise (CE) by including cardio exercises along with RE. Studying the effects of these two different training methods on left ventricular (LV) systolic and diastolic parameters and left atrial mechanical function is an important step toward understanding the effects of different types of exercise on cardiac function. This knowledge has significant implications for public health, as it can inform the development of targeted and effective exercise programs that prioritize cardiovascular health and reduce the risk of adverse outcomes. Therefore, the primary aim of this study is to comprehensively investigate the LV systolic and diastolic parameters of athletes who engage in RE and CE using ECHO, to contribute to the growing body of literature on the cardiovascular effects of different types of exercise. Forty-two amateur athletes aged between 17 and 52 were included in our study. The participants consisted of the RE (n = 26) group who did only resistance exercise during the weekly exercise period, and the CE group (n = 16) who also did cardio exercise with resistance exercises. After determining sports age (year), weekly exercise frequency (day), and training volume (min) in addition to demographic information of RE and CE groups, left ventricular systolic and diastolic parameters and left atrial functions were determined by ECHO. Findings from our study revealed that parameters including the left ventricular end-diastolic diameter (LVEDD) (p = .008), left ventricular end-diastolic volume (LVEDV) (p = .020), stroke volume index (SV-I) (p = .048), conduit volume (CV-I) (p = .001), and aortic strain (AS) (p = .017) were notably higher in the RE group compared to the CE group. Also left atrial active emptying volüme (LAAEV) of CE was higher than the RE group (p = .031). In conclusion, the cardiac parameters of the RE group showed more athlete's heart characteristics than the CE group. These results may help to optimize the cardiovascular benefits of exercise routines while minimizing the potential risks associated with improper training.
一些出于不同目的前往健身中心的个体单独进行抗阻运动（RE），而另一些个体则通过将有氧运动与 RE 结合进行组合运动（CE）。研究这两种不同训练方法对左心室（LV）收缩和舒张参数以及左心房机械功能的影响，是了解不同类型运动对心脏功能影响的重要步骤。这一知识对于公共健康具有重要意义，因为它可以为制定针对特定人群且行之有效的运动计划提供信息，优先考虑心血管健康并降低不良后果的风险。因此，本研究的主要目的是使用 ECHO 全面研究进行 RE 和 CE 的运动员的 LV 收缩和舒张参数，为不同类型运动对心血管影响的不断增长的文献做出贡献。我们的研究纳入了 42 名年龄在 17 岁至 52 岁之间的业余运动员。参与者包括仅在每周运动期间进行抗阻运动的 RE（n=26）组和也进行抗阻运动与有氧运动的 CE 组（n=16）。除了确定 RE 和 CE 组的运动年龄（年）、每周运动频率（天）和训练量（分钟）以及人口统计学信息外，还通过 ECHO 确定左心室收缩和舒张参数以及左心房功能。我们的研究结果表明，与 CE 组相比，RE 组的左心室舒张末期直径（LVEDD）（p=0.008）、左心室舒张末期容积（LVEDV）（p=0.020）、每搏输出量指数（SV-I）（p=0.048）、腔静脉容量指数（CV-I）（p=0.001）和主动脉应变（AS）（p=0.017）等参数明显更高。此外，CE 组的左心房主动排空容积（LAAEV）也高于 RE 组（p=0.031）。总之，RE 组的心脏参数比 CE 组更具运动员心脏特征。这些结果可能有助于在最大限度地降低不当训练相关风险的同时，优化运动方案的心血管益处。
