Abstract
Since the introduction of the “Physical Education and Health Curriculum Standards for Compulsory Education (2022 edition),” which emphasized the importance of physical education intensity, there has been scholarly debate and discussion among experts and physical education instructors. This study seeks to scientifically define an appropriate range of exercise intensity tailored to students of a specific age group during regular physical education classes. By focusing on junior high school students as the experimental subjects, this research employs experimental interventions, physical assessment techniques, and mathematical statistical analysis to validate the scientific basis of the exercise intensity guidelines outlined in the 2022 Curriculum Standards while addressing related concerns. The findings indicate that optimal heart rate range for exercise load intensity for junior high school students falls between 140 and 160 beats per minute.
