Abstract:
The purpose of the study was to find the effect of isolated and combined effect of Theraband resistance exercise and Medicine ball exercise on selected physical fitness and bio chemical variables of school boys. To facilitate the study 80 boys from Army Public School, Trivandrum District were randomly selected as subjects and their age was between 14 and 15 years. They were assigned into four groups of which one group served as Theraband Resistance exercise groups, second group served as Medicine Ball exercise group, third group served as combined Theraband Resistance exercise and Medicine Ball exercise group and the fourth group served as control group. The study was formulated as a true random group design, consisting of a pre test mid test and post test. The subjects (n=80) were randomly assigned to four equal groups of twenty each. The groups were assigned as Experimental Groups I, II, III and control group respectively. Pre tests were conducted for all the subjects on selected physical fitness, and biochemical variables such as abdominal strength, leg explosive strength, RBC and hemoglobin content. The experimental groups participated in their respective theraband practices, medicine ball practice and combined theraband exercises and medicine ball practices for a period of eight weeks. The midtest tests and post tests were conducted on the above said dependent variables after a period of theraband resistance practice, medicine ball practice and combined theraband resistance and medicine ball practices. The training programme was scheduled at 6.30 to 7.30 a.m. on 3 to 4 days in a week. The criterion measures such as abdominal strength was measured by bent knee sit ups, Leg explosive strength was measured by standing broad jump. Blood sample was collected for RBC count, hemoglobin test. To find out the difference between the pre test, mid test and post test, repeated measures ANOVA was used. When ever it found significant, the Newman kuels post-hoc test was administer. Analysis of covariance (ANCOVA) was applied and when ever the adjusted post-test means were found significant, the scheffe’s post-hoc test was administer to find out the paired means difference. To test the obtained results on variables, level of significance 0.05 was chosen and considered as sufficient for the study. The result reveals that the combined group (Theraband resistance exercise and Medicine ball exercise) have shown increased level of abdominal strength, leg explosive strength, hemoglobin content and RBC than the Theraband resistance exercise, Medicine ball exercise and control group.
