Abstract

This study aims to analyze the effect of dynamic warm-up on the physical readiness of lV MIN 3 Kota Medan grade elementary school students before doing sports activities. Optimal physical readiness is very important to prevent injury and improve student performance in sports. The research method used was a quasi-experimental method involving two groups: an experimental group that did dynamic warm-up and a control group that did not. Data were collected by measuring heart rate, joint flexibility, and muscle fatigue levels before and after sports activities. The results showed that dynamic warm-up significantly affected the increase in students' initial heart rate and joint flexibility, and reduced muscle fatigue levels after sports activities compared to the control group. Thus, it can be concluded that dynamic warm-up has a crucial role in preparing the physical condition of lV MIN 3 Medan City, grade elementary school students, increasing safety, and optimizing their participation in sports activities. The implication of this study is the importance of implementing dynamic warm-up as an integral part of every sports session at the elementary school level
