| Summary: | The objectives of this study are to evaluate common work fatigue symptoms and
also evaluate differences of physiological strain among construction workers. Total of
60 workers are divided into two groups which are high elevated construction workers
and ground level construction workers. Questionnaires consisting demographic data and
subjective work fatigue symptoms were distributed and there are also physiological
measurement such as heart rate have been collected. Workers required to wear
Vivosmart 3 on their wrist for heart rate measurements. Prior to performing
measurements, a study found that most of the construction workers have enough sleep
time between 7 hours to 9 hours. This could be explained by eliminating those ftigue
workers before performing the experimental measurements. For subjective work fatigue
symptoms, feel pain in the waist is the most common work fatigue symptoms with
prevalence rate for high elevated construction workers and ground level construction
workers are 80% and 100% respectively. It can lead to work musculoskeletal disorder
that can affect productivity and performance of the workers. The high level construction
workers have higher heart rate readings compared with those among ground level
construction workers. This indicates that high elevation construction workers have
higher physiological strain. This study shows that the subjective fatigue symptoms
questionnaires can be used to measure fatigue prevalence and heart rate is a suitable
physiological measurement to evaluate physiological strain that construction workers
encounter. |
