Effect of physical training on selected strength parameters of dexterous

Handedness is an attribute of humans defined by their unequal distribution of fine motor skill between the left and right hands. An individual who is more dexterous with the right hand is called right-handed (sinistralists), and one who is more skilled with the left is said to be left-handed (dextralists). The purpose of the study was to find out the effect of physical training on selected strength parameters of dexterous. For the propose 40 right hand dominance men students from department of engineering and technology, Annamalai University, Chidambaram, Tamilnadu, India were selected as subjects at random and their age range between 18-21 years, the selected subjects were divided in to two equal groups of twenty subjects each namely physical training (n=20) and control (n=20). The physical training group underwent training on strength for fifteen weeks, four days per week and sixty minutes per day including warming up and cooling down exercises. The maximum strength (handgrip strength on left and right hand) and explosive strength (throw for distance on left and right hand) were selected as dependent variables 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 strength variables (maximum strength and explosive strength) compared to control group. The difference between right and left hand on grip strength is insignificant.
