Abstract

The study on assessment of physical workload of timber harvesting workers in teak plantation aimed to determine the level of physical workload in various types of work during the harvesting operation. Data were collected from 93 workers from 18 types of labor in 4 plantations of the Forest Industry Organization, including Wang Chin, Mae Saroi, Khun Mae Khamme, and Mae Khampong in Phrae province. Body mass index (BMI) and heart rate were used for analysis. The results showed that 67.74% of the workers had a BMI in the normal range, 6.45% were underweight, and 25.81% were overweight. According to physiological parameters related to heart rate, the physical workloads of workers were categorized as light and medium level. The average resting heart rate was 87.57 beats per minute (bpm), while the average working heart rate was 108.73 bpm. The average relative heart rate at work was 22.52%. The average ratio of working heart rate to resting heart rate was 1.25 and the average ratio of working heart rate to 50% level of heart rate reserve was 0.75. These data could be used for planning and management in assigning specific tasks to the workers to get the most effective results while decreasing chances of injury and accident from task overload.
