Background:
This study explored the impact of physical exercise on internalizing and externalizing problem behaviors among Chinese middle school students.
Methods:
A cross-sectional survey was conducted among 6368 middle school students from Sichuan, Guangdong, Shandong, Henan, and Jiangxi provinces, using the International Physical Activity Questionnaire (IPAQ), Achenbach Youth Self-Report (YSR), and Depression-Anxiety-Stress Scales (DASS). Latent class analysis, multiple linear regression, and Kendall's tau coefficient tests were employed to analyze the data.
Results:
Physical exercise significantly reduced externalizing problem behaviors, including impulsivity (β = 0.188, p < 0.001), hostility (β = 0.129, p < 0.001), and aggressiveness (β = 0.158, p < 0.001), and also alleviated depression (β = 0.087, p < 0.01). Latent class analysis revealed that students with high levels of exercise had significantly fewer externalizing behaviors compared to low-level exercisers (p < 0.001). High-intensity exercise had greater effects, particularly on impulsivity and hostility. Rural male students exhibited higher levels of aggressiveness and hostility, while urban female students benefited more from exercise interventions.
Conclusion:
Physical exercise has a significant positive impact on reducing externalizing problem behaviors, especially impulsivity, hostility, and aggressiveness, among middle school students. However, its effects on internalizing behaviors are relatively limited. Intervention strategies should consider individual characteristics such as gender and location to maximize effectiveness.

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
