英国最新研究显示，只要练习马拉松并跑上6个月，就能达到血管减龄4岁的效果。

英国心脏病学家曼尼斯提领导的“马拉松研究”团队，透过最新一期《美国心脏病学学会杂志》，公开了这份研究结果。

受试者为2016和2017年参加年度“伦敦马拉松”赛事的138名跑者，他们的年龄介于21岁至69岁，平均37岁，49%为男性，先前皆无心脏病史，不过也不曾接受相关训练，当时是初次挑战42公里马拉松。

研究人员在受试者开始训练前，及6个月后挑战42公里成功后2周，测量他们的血压，透过核磁共振成像确认其血管硬化程度，并判断血管年龄。

研究结果显示，他们的血管年龄平均减少4岁。此外，血压相对较高或速度比较慢的年长跑者，看似最不适合参加马拉松，然而一旦开始训练，却是健康的最大受益者。

曼尼斯提表示，这证明“6个月内逆转血管老化的结果，是有可能的”，不过仍建议已患有心脏病或身体有其他状况者，应先咨询医生后再起步。
