It is established that an intensive training results in a lower average resting heart rate. Management of bradycardia in an athlete can be difficult given the underlying mechanisms are not clearly understood. The authors reviewed the different mechanisms described in the literature, including recent advances in physiology regarding remodeling of ion channels, which may partially explain bradycardia in athletes. Sinus bradycardia amongst athletes, especially endurance focused athletes, is common but difficult to apprehend. The underlying mechanisms are observably of multifactorial origin and likely incompletely elucidated by the current body of knowledge.
研究表明，强化训练会导致平均静息心率降低。由于运动员潜在的心动过缓机制尚不清楚，因此管理运动员的心动过缓可能具有挑战性。作者回顾了文献中描述的不同机制，包括最近关于离子通道重塑的生理学进展，这可能部分解释了运动员的心动过缓。运动员，尤其是耐力型运动员的窦性心动过缓很常见，但难以理解。潜在的机制显然是多因素的，并且可能尚未被当前的知识体系完全阐明。
