Introduction: The purpose of the present study is to investigate the effect of morning physical activity on the emotional self-regulation of male students in the first grade of elementary school.
Methodology: The current research was a semi-experimental type with a pre-test-post-test design, along with a control group. For this purpose, 38 students of the first grade of elementary school were selected by available sampling method and then randomly divided into two experimental and control groups. Garnevsky's and Kraij's emotional regulation questionnaire was used in both pre-test and post-test stages. According to the instructions of the General Sports Federation, the experimental group did morning exercise based on coordinated movements for eight weeks, and the control group did not receive any intervention. Data analysis was done through covariance analysis with a significance level of 0.05 by software with spss24.
Results: morning movement activities had a significant effect on improving students' emotion self-regulation and caused it to increase. The results of the Wilk’s Lambda test (P=0.0001) and intragroup and outgroup contrast test in the experimental group (P=0.0001) and the control group (P=0.09) showed the progress and significant difference of the experimental group compared to the control group.
Conclusion: Participating in morning movement activities based on coordinated movements increases students' emotional self-regulation. Therefore, it is suggested that sports coaches and relevant officials of schools should consider morning physical activity in the daily schedule of schools.

Key words: coordinated movements, emotion self-regulation, morning motor activity
