UNASSIGNED: During a multistage ultra-endurance event, a female well-trained cyclist underwent daily rest echocardiography and heart rate variability measurements to assess the cardiac function and the cardiac autonomic function.
UNASSIGNED: The athlete completed 3,345 km at 65% of her maximum heart rate and 39% of her maximum aerobic power. A progressive improvement of the systolic function for both the left ventricle and the right ventricle was observed during the event.
UNASSIGNED: Alterations were observed on the cardiac autonomic function with an imbalance between sympathetic and parasympathetic, but there was no sign of a significant correlation between the cardiac function and the autonomic cardiac function and no signs of cardiac fatigue either. Further analysis should be performed on a larger sample to confirm the obtained results.
■在多阶段超耐力赛事中,一名训练有素的女性自行车运动员接受了每日静息超声心动图和心率变异性测量,以评估心脏功能和心脏自主神经功能.
■该运动员以其最大心率的65%和其最大有氧能力的39%完成了3,345公里。在事件期间观察到左心室和右心室的收缩功能均逐渐改善。
■心脏自主神经功能改变,交感神经和副交感神经失衡,但是没有迹象表明心脏功能和自主神经心脏功能之间存在显着相关性,也没有心脏疲劳的迹象。应对较大的样品进行进一步分析以确认获得的结果。
