The Effect of Aerobic Exercise on Improving Cardiovascular Function and Coordination in Early Childhood Sports Training

Abstract

This study aims to determine the effect of aerobic exercise on improving cardiovascular function and coordination in early childhood sports training. This study employed a pre-experimental design with a One-Group Pretest-Posttest Design, utilizing a single group of subjects. The population and sample for this research and development consisted of athletes registered in a volleyball club in Sleman Regency. The sampling technique used was purposive sampling, with the following inclusion criteria: female volleyball athletes, willingness to participate as samples, aged 10–12 years, and a minimum training experience of 6 months. Based on the paired samples t-test analysis, the calculated t-value was greater than the t-table value, with a p-value (0.000) < 0.05. These results indicate that the calculated t-value is significantly larger than the t-table value. Consequently, there is a significant effect of aerobic exercise on improving cardiovascular function and coordination in early childhood sports training.
