Abstract:
Zenith athletic performance appears to be a role of three things: physical performance, balance diet, and sleep. The first two are widely understood as main pillars for achieving great performance but sleep plays an equally important role. Without sufficient sleep, effective recovery cannot take place which resultantly impacts an athlete’s performance. In Handball shooting the ball hard is not enough to beat a good goalie; accuracy is essential. Shooting for the corners is one of the important principles of shooting. The accuracy is dependent on our brain functioning better brain functioning can be achieved through proper recovery and rest. The objective of the study is to find out how sleep deprivation will affect the shooting accuracy of handball players. For the purpose of the study, the sampling technique used was probability random sampling, where a total of 15 male handball players, from Lakshmibai National Institute of Physical Education, Gwalior selected (age group 18 yrs – 24 yrs). Mean & standard deviation (SD) of their age was 20.64 ± 0.92 (yrs). The experiment was conduct for three days. The experimental group was first provided with complete 8 hour sleep and shooting accuracy test was conducted. The same experimental group after one day gap was deprived form one night sleep and then shooting accuracy test was conducted. The mean shooting accuracy score of Day one was (8.80) and the mean shooting accuracy score of Day three was (6.26) and the mean difference the Day one & Day three shooting accuracy was (2.54) & tested by‘t’ test. The significance difference exists between pre-test mean and post-test mean because calculated value 7.87 is greater than the tabulated value 2.14. Day two scores were found to be statistically significant at.05 level of confidence. On the basis of obtain data a complete sleep can play vital role in enhancing the accuracy of shooting ability of handball players.
