密集训练导致运动员的心脏 (AH),其特点是心脏腔扩大. 这项研究证实AH与运动员显著扩大心房和心肌质量增加有关.
科学领域:
- 心脏病学 心脏病学
- 运动医学 运动医学
- 运动生理学 运动生理学
背景情况:
- 强化训练会导致血液动力学变化,增加心脏输出量和中风量,提高运动表现.
- 这些适应可以导致心室扩大,包括心房,可能导致运动员心脏 (AH).
- 对于运动员心脏病中的心房扩大存在有限的大规模数据.
研究的目的:
- 调查竞技运动员中心房扩大的患病率和特征.
- 确定运动员的心脏 (AH) 和心室尺寸之间的关联,特别是左心室质量和心房区域.
主要方法:
- 包括646名竞技运动员 (≥18岁) 在2020年4月至2021年10月期间接受了参加前查.
- 根据运动员心脏 (AH) 的定义分层的运动员:生理心脏体积>13.0毫升/千克 (男性) 或>12.0毫升/千克 (女性).
- 分析计算心脏绝对体积,左心室质量,左心房 (LA) 区域和右心房 (RA) 区域.
主要成果:
- 18.3%的运动员 (646人中118人) 呈现运动员心脏 (AH).
- 患有AH的运动员表现出显著增加的心脏体积 (969.4毫升 vs. 841.3毫升),左心室质量 (206.6克 vs. 182.7克),LA面积 (15.4厘米2 vs. 14.3厘米2) 和RA面积 (15.8厘米2 vs. 14.5厘米2).
- 后勤回归证实AH作为增加LV质量,LA面积和RA面积的独立预测因素.
结论:
- 运动员的心脏 (AH) 与心房 (左侧和右侧) 的显著扩大有关.
- 增加心脏肌肉质量,特别是左心室质量,是运动员心脏的关键特征.
- 这些发现突出显示了心脏重塑,发生在响应密集体育训练.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
