: The association between right ventricular myocardial fiber deformation and nutrition in weightlifters has not been fully characterized. This study analyzed nutritional factors and right ventricle speckle tracking echocardiography parameters in weightlifters before and after bench press exercises. : This interventional study examined the effects of bench press exercises on myocardial function. Nutritional parameters were assessed prior to exercise. Echocardiography with speckle tracking using vector velocity analysis was performed before and immediately after the bench press exercise. This study included a group of non-elite athlete weightlifters and a non-athlete control group to compare right myocardial function. In the athlete group, transthoracic echocardiograms (TTEs) were conducted before and after the exercise to assess changes in systolic and diastolic right heart function. A cohort of 30 weightlifters from 2014 who continued regular training was re-evaluated in 2024, and nutritional data were collected. Data analyses included ANOVA and Student's T-tests, and correlation coefficients were calculated to explore associations with speckle tracking results. : This study involved 211 male weightlifters and a control group of 60 non-athletes. Measured values for the control group and athletes before and after bench press exercise were as follows: right longitudinal global strain (-27.31 ± 1.47, -23.55 ± 2.37, -30.98 ± 2.12); right global longitudinal strain rate (-1.79 ± 0.078, -1.48 ± 0.33, -2.88 ± 0.259 1/s), all < 0.001; and isovolumic acceleration (2.38 ± 0.22, 3.52 ± 0.15, 6.66 ± 0.88 m/s, < 0.001). Following exercise, right intraventricular synchrony increased, and longitudinal strain delay decreased (144.88 ± 22.52, 168.92 ± 29.35, 98.27 ± 12.11 ms, < 0.001). The follow-up group demonstrated a similar response to exercise as the other weightlifters. Right ventricular longitudinal strain showed correlations with protein, vitamin E, and zinc levels (R = 0.399, = 0.021; R = 0.378, = 0.03; R = 0.566, < 0.01), and right ventricular radial velocities correlated with group B vitamins. : Weightlifters show less right ventricular deformity before exercise compared to controls, but their strain increases significantly post-exercise. Speckle tracking values might correlate with nutrition.
举重运动员右心室心肌纤维变形与营养之间的关联尚未得到充分阐明。本研究分析了卧推运动前后举重运动员的营养因素和右心室斑点追踪超声心动图参数。：这项干预性研究考察了卧推运动对心肌功能的影响。在运动前评估营养参数。在卧推运动前及运动后即刻采用向量速度分析进行斑点追踪超声心动图检查。本研究纳入了一组非精英运动员举重运动员和一个非运动员对照组，以比较右心功能。在运动员组中，在运动前后进行经胸超声心动图（TTE）检查，以评估右心收缩和舒张功能的变化。对2014年持续进行常规训练的30名举重运动员队列在2024年进行重新评估，并收集营养数据。数据分析包括方差分析和学生t检验，并计算相关系数以探索与斑点追踪结果的关联。：本研究涉及211名男性举重运动员和一个由60名非运动员组成的对照组。对照组和运动员在卧推运动前后的测量值如下：右心室纵向整体应变（-27.31±1.47、-23.55±2.37、-30.98±2.12）；右心室整体纵向应变率（-1.79±0.078、-1.48±0.33、-2.88±0.259 1/s），均<0.001；等容加速度（2.38±0.22、3.52±0.15、6.66±0.88 m/s，<0.001）。运动后，右心室内同步性增加，纵向应变延迟减少（144.88±22.52、168.92±29.35、98.27±12.11毫秒，<0.001）。随访组对运动的反应与其他举重运动员相似。右心室纵向应变与蛋白质、维生素E和锌水平相关（R = 0.399，P = 0.021；R = 0.378，P = 0.03；R = 0.566，P<0.01），右心室径向速度与B族维生素相关。：与对照组相比，举重运动员在运动前右心室变形较小，但运动后其应变显著增加。斑点追踪值可能与营养相关。
