Law enforcement academies, designed to prepare recruits for their prospective career, represent periods of high physical and mental stress, potentially contributing to recruits' injuries. Managing stress via monitoring training loads may mitigate injuries while ensuring adequate preparation. However, it is vital to first understand an academy's typical training load. The aim of this study was to profile the typical training load of law enforcement recruits over the course of 22 weeks. Data were prospectively collected using global positioning system (GPS) units placed on recruits during a portion of the academy training, while a desktop analysis was retrospectively applied to six other classes. A Bland-Altman plot was conducted to assess the agreement between the two methods. A linear mixed model was conducted to analyse the difference in distances covered per week, while other variables were presented graphically. Adequate agreement between the desktop analysis and GPS units was observed. Significant differences (-value < 0.01) in distance covered (9.64 to 11.65 km) exist between weeks during early academy stages, which coincide with increases (~6 h) in physical training. Significant decreases in distances were experienced during the last five weeks of academy training. Most acute:chronic workload ratios stayed between the proposed 0.8 to 1.3 optimal range. Results from this study indicate that large increases in training occur early in the academy, potentially influencing injuries. Utilizing a desktop analysis is a pragmatic and reliable approach for instructors to measure load.
执法学院旨在为学员未来的职业生涯做好准备，在此期间，学员会经历高强度的身心压力，这可能导致学员受伤。通过监测训练负荷来管理压力可以减轻受伤风险，同时确保充分的准备。然而，首先了解学院的典型训练负荷至关重要。本研究旨在描述执法学员在 22 周的课程中典型的训练负荷情况。研究使用全球定位系统（GPS）设备在学员接受部分学院培训时收集数据，同时回顾性地应用于另外六个班级的桌面分析。通过 Bland-Altman 图评估两种方法之间的一致性。通过线性混合模型分析每周覆盖距离的差异，同时以图形方式呈现其他变量。桌面分析和 GPS 设备之间的一致性良好。在早期学院阶段，不同周之间的覆盖距离（9.64 至 11.65 公里）存在显著差异（-值 < 0.01），这与体能训练的增加（~6 小时）相符。在学院培训的最后五周，距离明显减少。大多数急性：慢性工作量比保持在建议的 0.8 到 1.3 的最佳范围内。本研究结果表明，学院早期训练量会大幅增加，这可能会影响受伤情况。利用桌面分析是教官衡量负荷的实用且可靠的方法。
