Abstract
The purpose of the study was to determine the effect of varied frequency and duration of aerobic dancing on selected physical variables of handball players. To achieve the purpose of the present study, Sixty Untrained healthy school boys of Kendriya Vidyalaya Bengaluru Region, Karnataka, India were selected as subjects at random and their ages ranged from 14 to 17 years. The subjects were divided into four equal groups of twenty each. group-I acted as experimental group-I (30 minutes with 50% intensity aerobic exercise, group-II acted as experimental group-II (45 minutes with 60% intensity aerobic exercise), group-III acted as control group the requirement of the experiment procedures, testing as well as exercise schedule was explained to the subjects so as to get full co-operation of the effort required on their part and prior to the administration of the study. The duration of experimental period was 12 weeks. After the experimental treatment, all the sixty subjects were tested on their physical variables. This final test scores formed as post test scores of the subjects. the pre test and post test scores were subjected to statistical analysis using analysis of covariance (ANCOVA) to find out the significance among the mean differences, whenever the ‘F’ ratio for adjusted test was found to be significant; Scheffe’s post-hoc test was used. In all cases 0.05 level of confidence was fixed to test hypotheses. In comparing the effect of 30 minutes with 50% intensity aerobic exercise, 45 minutes with 60% intensity aerobic exercise and control groups physical variables, from the obtained f-ratio, it was observed that 60% intensity group showed significant difference on increasing speed and explosive power.
