Abstract：
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.
摘要：
一些出于各种目的去健身中心的人单独进行阻力运动（RE），而其他人则通过将有氧运动与RE一起进行联合运动（CE）。研究这两种不同的训练方法对左心室（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功能影响的重要一步。这些知识对公共卫生有重大影响，因为它可以为制定有针对性和有效的运动计划提供信息，以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全面调查从事RE和CE的运动员的LV收缩和舒张参数，为越来越多关于不同类型运动对心血管影响的文献做出贡献。我们的研究包括42名年龄在17至52岁之间的业余运动员。参与者由RE（n=26）组组成，他们在每周的锻炼期间只进行抵抗运动，CE组（n=16）也进行了有氧运动和阻力运动。确定运动年龄（年）后，每周运动频率（天），以及培训量(分钟)，以及RE和CE组的人口统计信息，通过ECHO测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，参数包括左心室舒张末期直径（LVEDD）（p=.008），左心室舒张末期容积（LVEDV）（p=0.020），每搏量指数（SV-I）（p=.048），导管体积（CV-I）（p=.001），与CE组相比，RE组的主动脉应变（AS）（p=0.017）明显更高。CE的左心房主动排空（LAAEV）也高于RE组（p=.031）。总之,RE组的心脏参数比CE组表现出更多的运动员心脏特征。这些结果可能有助于优化运动常规的心血管益处，同时最大程度地减少与不当训练相关的潜在风险。
