Aims
The aim of this study is to investigate the effect of mine protective clothes on reaction time and vision performance.
Methods
12 healthy males with mean age 26.83±3.09 and normal Body Mass Index (BMI) was recruited in the current study. Each samples was investigated in climate chamber with 35°C and 30% relative humidity. Physiologic Strain Index score (PSI), Reaction time and vision fatigue frequency was measured with and without mine protective clothes and data were analyzed by Wilcoxon and Friedman test.
Results
Without the mine protective clothing the mean PSI was 1.62)0.29(, Reaction time 0.5739)0.048(, Oral temperature 36.5)0.33(, Heart rate 101.33)4.49( and Vision fatigue frequency was 37.65)3.36(. and with mine protective clothing the mean PSI was 3.19)0.36(, Reaction time 0.721)0.09(, oral temperature 37.23)0.20(, Heart rate 111.41)5.16( and Vision fatigue frequency was 35.45)3.26(. Wilcoxon test showed that the differences of variables between two conditions was significant (p=0.002).
Conclusion
Using of the mine protective clothing causes increase in reaction time and vision fatigue due to heat strain that cause human error.
