Results of investigation into the physical exertion of the log skidding workers: tractor driver, winch operator and choker are presented. The investigation consisted of laboratory and field measurements and included measurements of the heart rate and assessment of the work effect, the work time structure, and the worker's physical exertion and energy consumption. According to the average rate during daily work, the physical exertion of the tractor driver and winch operator was classified as low exertion (75-95 min-1), whereas that of the choker was established as medium exertion (96-115 min-1). Energy consumption was calculated for the daily working time of 262 minutes, according to field measurements and for normal eight-hour work. According to field measurement values the tractor driver's and winch operator's work was categorized as light work (1.23-2.51 MJ) and that of the choker as heavy work (2.52-6.30 MJ). According to the values for eight-hour work, the tractor driver's and the winch operator's jobs were classified as heavy work (2.52-6.30 MJ/8 h) and the choker's job as the heaviest (6.31-10.47 MJ/8 h).
介绍了对集材工人（拖拉机驾驶员、绞盘机操作员和挂钩工）体力消耗的调查结果。该调查包括实验室和现场测量，涵盖心率测量、工作效果评估、工作时间结构以及工人的体力消耗和能量消耗。根据日常工作中的平均心率，拖拉机驾驶员和绞盘机操作员的体力消耗被归类为低强度（75 - 95次/分钟），而挂钩工的体力消耗被确定为中等强度（96 - 115次/分钟）。根据现场测量结果并针对正常的八小时工作日，计算了262分钟工作日的能量消耗。根据现场测量值，拖拉机驾驶员和绞盘机操作员的工作被归类为轻体力工作（1.23 - 2.51兆焦耳），挂钩工的工作为重体力工作（2.52 - 6.30兆焦耳）。根据八小时工作的值，拖拉机驾驶员和绞盘机操作员的工作被归类为重体力工作（2.52 - 6.30兆焦耳/8小时），挂钩工的工作为最重体力工作（6.31 - 10.47兆焦耳/8小时）。
