A growing body of literature supports an association between long-term endurance exercise and the development of atrial fibrillation (AF). Given the benefits of lifelong exercise, a better understanding of this association is critical to allow healthcare providers to counsel aging exercisers on the proper "dose" of exercise to maximize health benefits but minimize AF risk. The current study examines the relationship between specific aspects of training volume and intensity and the occurrence of AF among older runners in order to better understand what aspects of endurance exercise may contribute to the development of AF. The study was an Internet-based survey of endurance training and health characteristics of runners 35 years of age and older. A total 2819 runners participated and 69 (2.4%) reported a current or prior diagnosis of AF. Among "traditional" risk factors, runners reporting AF were older, more likely to be male, and had higher rates of hypertension and diabetes. Among training characteristics, only accumulated years of training was associated with AF. In contrast, average weekly mileage, training pace, and days of training per week were not associated with AF. In a multivariable analysis that included chronologic age, sex, diabetes, and hypertension, accumulated years of training remained significantly associated with the report of AF. These findings suggest that the relationship between chronic endurance exercise and AF is dependent on the accumulated training duration but does not appear to be influenced by specific training characteristics such as frequency or intensity of endurance exercise. Further confirmation of these relationships may help healthcare providers counsel exercisers on optimal training habits and identify endurance athletes who are at risk for the development of AF.
越来越多的文献支持长期耐力运动与房颤（AF）发生之间存在关联。鉴于终身运动的益处，更好地理解这种关联对于医疗保健提供者为老年运动者提供咨询至关重要，以便他们能就适当的运动“剂量”提供建议，从而在使健康益处最大化的同时将房颤风险降至最低。本研究旨在探讨训练量和强度的具体方面与老年跑步者房颤发生之间的关系，以便更好地了解耐力运动的哪些方面可能导致房颤的发生。该研究是一项基于互联网的调查，涉及35岁及以上跑步者的耐力训练和健康特征。共有2819名跑步者参与，其中69人（2.4%）报告目前或既往被诊断为房颤。在“传统”风险因素方面，报告患有房颤的跑步者年龄更大，更可能为男性，高血压和糖尿病发病率更高。在训练特征方面，只有累计训练年限与房颤有关。相比之下，平均每周里程数、训练配速和每周训练天数与房颤无关。在一项包括年龄、性别、糖尿病和高血压的多变量分析中，累计训练年限仍与房颤报告显著相关。这些发现表明，慢性耐力运动与房颤之间的关系取决于累计训练时长，但似乎不受耐力运动频率或强度等特定训练特征的影响。对这些关系的进一步证实可能有助于医疗保健提供者就最佳训练习惯为运动者提供咨询，并识别有房颤发生风险的耐力运动员。
