Abstract:
The purpose of this study was to determine the effect of the modified pull-up machine on the pull-up and flexed arm hang performance of elementary age children. A total of 53 male and female subjects were selected by stratified random sample from Lancaster Elementary School in Huntington, Indiana. The subjects were randomly assigned to either a control group or an experimental group, and assigned a number to ensure anonymity. The training of the experimental group lasted 12 weeks with training sessions on the modified pull-up held three tines per week. Pretests and post-tests were given to each group and included height, weight, skinfold measures as well as scores on the modified pull-up and regular pull-up or flexed arm hang. Means, standard deviations and analysis of variance were determined on physical characteristics as well as for the test of the modified pull-up and regular pull-up or flexed arm hang. The results show no significant difference pre or post-test on physical characteristics of the two groups. The data ANOVA revealed there were significant differences found between the control and experimental groups on modified pull-ups. However, there were no significant differences found between the two groups on the regular pull-up or flexed arm hang.Comparing modified pull-ups to regular pull-ups in the control group, a significant difference was found. For the experimental group, no significant differences were found between the modified pull-up and regular pull-up or flexed arm hang.
