Assessment of psychomotor reactions and hemodynamic index subject to physical strain and deafness nature of sportsmen with hearing impairment and those who do not do sports with hearing impairment

The aim of the study was – to evaluate psychomotor reactions and hemodynamic indices of sporstmen with hearing impairment and male persons who did not go in for sport. Hypothesis – The time of psychomotor reaction comparing sporstmen and people who do not do sports with hearing impairment subject to physical strain the time will be longer of those who do not go in for sport. And according deafness nature the reaction time will be longer in the group of sporstmen subject to acquired deafness nature. Objectives of the study: 1. To evaluate the time of simple and complex reaction before and after strain sample of sportsmen with hearing impairment and people who do not do sports with hearing impairment. 2. To estimate psychomotoric simple and complex reaction time of sportsmen with hearing impairment, subject to deafness nature before and after strain sample. 3. To evaluate hemodynamic parameters (double product) simple and complex reaction change of sportsmen with hearing impairment invoking 6 min. walking test subject to deafness nature. Research methods. Twenty two young people with hearing impairment took part in the study. There were deaf national basketball team players in the searching group (age 23,80±2,6), (45,5%., n=10), People with hearing impairment who do not go in for sport were in a control group (age 21,75±1,8 ), (54,5%., n=12). Researches were made in Lithuanian sports university (LSU) using analyser (DPA – 1) (p. No. 5251; 2005 08 25) of human hands and legs movements dynamic parameters in the laboratory of movement control. Results. Simple and complex reaction time was statistically different only after physical strain sample among sportsmen with hearing impairment and those who do not go in for sport (p0,05). 3. There was statistical significant alteration of complex reaction time and hemodynamic parameters (double product) of sporstmen with acquired hearing impairment after 6 minutes walking test. Recommendations: It is recommended that people with hearing impairment should go in for sports because it would help to keep attention and concentration. Keywords: deafness, psychomotor, reaction time
