Relationship between morphometric indicators of dominant hand and psychomotor reaction and accuracy of the movements

The object of research – the relationship between the morphometric indices of dominant hand, psychomotor reactions, accurate and quick movements, and. The aim – to identify and compare data about accurate movements, psychomotor reactions in association with the morphometric parameters of the dominant hand among healthy young athletes men. Objectives: 1. Investigate the distribution of hand dominance and psychomotor reactions investigated the relationship between the mens. 2. Set and compare the accuracy of movements and psychomotor reactions relationship with morphometric parameters of hand. 3. Determine and compare the accuracy of movements and psychomotor reactions relationship between the movements of the right and left hand. Hypothesis – is likely to be a correlation between the dominant hand movement and accuracy. Results. Correlation analysis between the handedness, simple and complex task reaction time and other parameters of motion , the movement of the right and left hand showed that the average inverse relationship (-0,4 0,05). It should be noted that the right-handed striking correlation coefficient valuesare higher. The survey results showed that boys studied the motion response time is improved, the motion carried with your left hand (for simple and complex task ). However, the accuracy of the motion , the time to target and maximum hand speed is higher when guys act plays right-handed. Of the results of the correlation analysis revealed a statistically significant (p 0,05). Conclusions: 1. It was established that most of the men attributable crisp right-handed (57 percent). Mediocre and right-handed (33 percent). It was found that there was an average inverse correlation (-0.4 0.05) between the dominant hand, the reaction time, time till target and the accuracy of motion. 2. Comparing the precision of movements and psychomotor reactions in association with the arms of morphometric parameters set weak or very weak correlation (r 0.05) between the left and right arm length, weight and dynamometry. 3. Investigated the greater accuracy of movement in the right hand than the left between boys. 4. A comparison of the accuracy of movements and psychomotor reactions relationship, found that there was moderate or strong correlation (r > 0.6; p < 0.05) between the reaction time of the right and left hand; accuracy and range of motion of the time and average speed. 5. Found that the motion of boys left hand simple psychomotor reaction time is shorter than the movement of the right hand ( p < 0.05)
