Dataset belonging to Relationship between Academic Stress, Mental Fatigue and Training Load in Adolescent Soccer Players

This dataset was produced as part of the research project that aims to investigate the relationship between academic stress, mental fatigue and training load in adolescent soccer players. Using a prospective cohort design, 35 players (age 16.1 ± 1.2 years; length ± 8.8 cm; body mass 64.4 ± 9.9 kg) were monitored for the second half of the 2022-2023 season. Players reported academic stress, mental fatigue and rating of perceived exertion on a daily basis. In addition, anonymized GPS and heart rate data were collected during training sessions using Polar Team Pro. After multiple imputation, multilevel analysis was conducted to predict internal load, i.e. Rate of Perceived Exertion (RPE) and Training Impulse (TRIMP).

The dataset contains the anonymized data from the training sessions, as well as the accompanying codebooks, documentation and scripts. As the dataset does not contain sensitive information, it can be used freely.

本数据集源自一项旨在探究青少年足球运动员学业压力、心理疲劳与训练负荷之间关联的研究项目。本研究采用前瞻性队列研究设计，对2022-2023赛季下半程的35名运动员（年龄16.1±1.2岁；身高±8.8厘米；体重64.4±9.9千克）开展追踪监测。运动员每日需报告自身学业压力、心理疲劳状况以及自觉用力评分。此外，研究团队借助Polar Team Pro设备，在训练过程中采集了匿名化的全球定位系统（GPS）与心率数据。经多重插补处理后，研究人员开展多水平分析，以预测内部负荷指标，即自觉用力评分（Rating of Perceived Exertion, RPE）与训练冲量（Training Impulse, TRIMP）。本数据集涵盖训练课程的匿名化数据，以及配套的编码手册、说明文档与分析脚本。因数据集未包含敏感信息，可自由使用。
