ArticleThe aim of this study was to predict the work strain indicators for construction workers
and to work out measures for prevention of strain at work. Subjective and objective research
methods were utilized in the research, including survey, work intensity measurements (Borg
Scale), work strain index, fatigue index and work ability index determination, objective blood
pressure and pulse measurements. Statistical analysis with significance calculations was carried
out. The limitation of this study is the small number of subjects involved in the research.
Subjective evaluation of fatigue index and strain index resulted in moderate and somewhat hard
work heaviness categories accordingly to Borg Scale. Measurements of heart rate, blood pressure
approved work strain of employees of both professions does not exceed the admissible heart rate
limit during physical load. The research proved that the strongest work strain predictors were
connected with psycho-social risks rather than with physical ones
