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 isolated and combined physical training on muscular strength among school handball players. For the propose 30 right hand dominance boy students from Nagapattinam 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 muscular strength (Hand Grip Strength 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 strength parameter. The difference between right and left hand on muscular strength is significant. However, the percentage of improvement for the variable was in-favor of right hand compared to left. Hence, it was concluded that physical training may be given to improve the dexterous (use of hands) level and quality.
