Trail running involves off-road running over different surfaces of positive and negative unevenness. Given these particularities and the associated physical demands, it is essential to understand this relationship and how fitness levels influence performance. This study aimed to analyze fitness level variations during different times of the season and establish a relationship between changes in fitness levels and accumulated load. Twenty-five trail running athletes (age: 36.23 ± 8.30 years) were monitored over 52 weeks. Three periods of assessment were implemented, while load between those periods was calculated. Athletes were monitored daily by global positioning systems. The collected data included distance covered, duration, and rate of perceived exertion (RPE), which were used to obtain session-RPE. Additionally, maximal aerobic speed, vertical jump, and dynamic balance were tested periodically. Moderate inverse correlations were found between assessment 1 and 2 for total sRPE and vertical jump: countermovement jump (VJ: CMJ) ( = -0.349), and Y balance test: left posterolateral (YBT: LPL) ( = -0.494). Similar correlations were found between assessment 2 and 3 for total sRPE and VJ: CMJ ( = -0.397), and vertical jump: drop jump (VJ: DJ) ( = -0.395). The results suggest that trail running coaches should monitor and assess dose-response relationships and possible anterior asymmetries of dynamic balance performance.
越野跑涉及在具有不同正负不平度的各种路面上进行越野跑步。鉴于这些特殊性以及相关的身体要求，了解这种关系以及体能水平如何影响表现至关重要。本研究旨在分析赛季不同时间的体能水平变化，并建立体能水平变化与累积负荷之间的关系。对25名越野跑运动员（年龄：36.23±8.30岁）进行了为期52周的监测。实施了三个评估阶段，同时计算了这些阶段之间的负荷。通过全球定位系统对运动员进行每日监测。收集的数据包括跑步距离、时长和主观用力程度（RPE），这些数据用于获得单次训练的RPE。此外，定期测试最大有氧速度、垂直跳跃和动态平衡。在评估1和评估2之间，总sRPE与垂直跳跃的反向移动跳（VJ：CMJ）（r = -0.349）以及Y平衡测试的左后外侧（YBT：LPL）（r = -0.494）之间发现了中度负相关。在评估2和评估3之间，总sRPE与VJ：CMJ（r = -0.397）以及垂直跳跃的下落跳（VJ：DJ）（r = -0.395）之间也发现了类似的相关性。结果表明，越野跑教练应监测和评估剂量反应关系以及动态平衡表现可能存在的前侧不对称性。
