Nine ski mountaineering (Ski-Mo), ten Nordic-cross country (NCC), and twelve world elite biathlon (Bia) athletes were evaluated for cardiopulmonary exercise test (CPET) performance and pronounced echocardiographic physiological cardiac remodeling as a primary aim of our descriptive preliminary report. In this context, a multicenter retrospective analysis of two-dimensional echocardiographic data including speckle tracking of the left ventricle (LV-GLS) and CPET performance analysis was performed in 31 elite world winter sports athletes, which were obtained during the annual sports medicine examination between 2020 and 2021. The matched data of the elite winter sports athletes (14 women, 17 male athletes, age: 18-32 years) were compared for different CPET and echocardiographic parameters, anthropometric data, and sport-specific training schedules. Significant differences could be revealed for left atrial (LA) remodeling by LA volume index (LAVI, = 0.0052), LV-GLS ( = 0.0003), and LV mass index (LV Mass index, = 0.0078) between the participating disciplines. All participating athletes showed excellent performance data in the CPET analyses, whereby significant differences were revealed for highest maximum respiratory minute volume (VE ) and the maximum oxygen pulse level across the participating athletes. This study on sport specific physiological demands in elite winter sport athletes provides new evidence that significant differences in CPET and cardiac remodeling of the left heart can be identified based on the individual athlete's training schedule, frequency, and physique.
本描述性初步报告的主要目的是评估9名滑雪登山（Ski-Mo）运动员、10名北欧越野滑雪（NCC）运动员和12名世界精英冬季两项（Bia）运动员的心肺运动测试（CPET）表现以及明显的超声心动图生理性心脏重塑情况。在此背景下，对31名世界精英冬季运动运动员进行了二维超声心动图数据的多中心回顾性分析，包括左心室斑点追踪（LV-GLS）和CPET表现分析，这些数据是在2020年至2021年年度运动医学检查期间获得的。对精英冬季运动运动员（14名女性，17名男性运动员，年龄：18 - 32岁）的匹配数据进行了比较，涉及不同的CPET和超声心动图参数、人体测量数据以及特定运动的训练计划。在参与的各项目之间，通过左心房容积指数（LAVI，P = 0.0052）、LV-GLS（P = 0.0003）和左心室质量指数（LV Mass index，P = 0.0078）可发现左心房（LA）重塑存在显著差异。所有参与运动员在CPET分析中均表现出优异的成绩数据，其中参与运动员的最高最大呼吸分钟通气量（VE）和最大氧脉搏水平存在显著差异。这项关于精英冬季运动运动员特定运动生理需求的研究提供了新的证据，即根据运动员个人的训练计划、频率和体格，可以确定CPET和左心心脏重塑的显著差异。
