The duration of the defensive reaction to a sudden attack

Reaction time research is an important parameter for the examination of possible human motor responses, especially in forensic biomechanics. Factors influencing the reaction time can be classified by many criterions. The most relevant theoretical and practical factors are alcohol, stimulating drugs, age, training, fatigue, subject's orientation towards stimulus, warning of incoming stimulus and psychical tension. Primary, we were interested in impairment of human's reaction time as a result of alcohol administration. This article refers to presentation of results of our pilot research project, which treats of the reaction time on random stimulus that requires complex motor response. We found no impairment up to 0,3‰ BAC, but overall relationship is expressed by quadratic regression
