Impact of isolated and combined dextrality and sinistrality physical training on reaction speed among school handball players
AUTHOR(S): K Kathiravan and Dr. S Vijay
Handedness is an attribute of humans defined by their unequal distribution of fine motor skill between the left and right hands. Dexterous refers to the skill and grace in physical movement, especially in the use of the hands, adroitness. An individual who is more dexterous with the right hand is called right-handed (dextralists), and one who is more skilled with the left is said to be left-handed (sinistrality). The purpose of the study was to find out the effect of isolated and combined physical training on reaction speed among school handball players. For the propose 30 right hand dominance boy students from Nagappatinam district, Tamilnadu, India were selected as subjects at random and their age range between 12-14 years, the selected subjects were divided in to three equal groups of ten subjects each namely dextrality physical training group (n=10), sinistrality physical training group (n=10), and combined dextrality and sinistrality physical training group (n=10). The physical training group underwent training for fifteen weeks, four days per week and sixty minutes per day including warming up and cooling down exercises. The reaction speed (ruller drop test) was selected as dependent variable and tested before and after the experimental period for both the groups. The collected data were analyzed by using ANCOVA. Further, independent‘t’ was calculated to find out the difference between left and right hand and the percentage was also calculated to find out the level of improvement on dexterous. Level of confidence was fixed at 0.05. The result of the study shows that the physical training improved the selected speed parameters (Transferring speed and reaction speed) compared to control group. The difference between right and left hand on speed is insignificant. However, the percentage of improvement for the variable was in-favor of left hand compared to right. Hence, it was concluded that physical training may be given to improve the dexterous (use of hands) level and quality.
