Abstract

Fatigue behind the wheel has been addressed repeatedly for at least 15 years. Various research projects, studies, and systems have been developed to prove the effect of fatigue on the number of accidents and possibly to inform drivers that this situation has occurred. The article examines the influence of stimulants on the fatigue of young agricultural machinery drivers. Commonly available means for reducing driver fatigue were chosen as stimulants (coffee, tea, maté, guarana, energy drink, lemon extract with sugar). A special test station with automatic reaction time evaluation was developed to test drivers' reaction ability (responsiveness). Furthermore, the effects on the physical condition of the tested persons (systolic blood pressure, diastolic blood pressure, blood pressure amplitude and heart rate) were investigated. The conducted experiments confirmed a statistically significant effect of all tested stimulants, except for tea, for which no statistically significant changes in the monitored parameters were observed.
