Effects of site type in physical education courses on changes in grit and exercise addiction among college students: a comparative quasi-experimental study
This quasi-experimental study involving 818 Chinese college students demonstrates that physical education courses held in open natural settings are more effective than those in strictly site-constrained environments at increasing grit and persistence while reducing exercise addiction, with distinct patterns in the relationship between these changes varying by setting and gender.

For decades, educators and psychologists have searched for the secret ingredient that helps people stick with difficult goals. They call this quality "grit." It is not just about being tough; it is the ability to keep working hard when things get difficult, combined with a steady, long-term interest in a specific aim. At the same time, there is a growing concern that physical activity, usually seen as a healthy habit, can sometimes tip over into something unhealthy. This is known as exercise addiction, where a person feels compelled to work out even when it causes harm, conflict, or distress. The question researchers are now asking is simple but profound: does the place where we exercise change how these two things develop? It turns out that the walls of a gym or the boundaries of a sports field might be more than just physical limits; they could be shaping our minds in ways we did not expect.
A team of researchers in China set out to test this idea by looking at how different types of physical education classes affect college students. They focused on two very different environments. On one side, they had courses held in open natural settings, such as mountains and forests, where students learned skills like mountaineering and wilderness survival. These classes were defined by uncertainty and the need to adapt to the wild. On the other side, they had strictly site-constrained courses, which took place on standard fields and courts for sports like basketball, soccer, and tennis. These activities happen within clear, fixed lines and follow rigid rules. The researchers wanted to see if the wild, unpredictable nature of the outdoors produced different results in a student's character and mental health compared to the controlled, predictable environment of a traditional sports field.
To find the answer, the team followed 818 undergraduate students over the course of a single semester. Half of the students were in the outdoor groups, while the other half were in the traditional sports groups. Before the classes began, the researchers measured how much grit each student had and how likely they were to develop an unhealthy obsession with exercise. They measured these same things again at the very end of the semester. The goal was to see who changed, how they changed, and whether the type of class they attended made a difference.
The results revealed a clear split between the two groups. Students who spent their semester in the open natural settings showed a noticeable improvement in their grit. Specifically, they became better at persisting through effort and difficulty. Their scores for this quality went up significantly. At the same time, their tendency toward exercise addiction went down. They were less likely to feel that they had to exercise compulsively. In contrast, the students in the traditional sports classes showed almost no change in either direction. Their levels of grit remained steady, and their risk of exercise addiction did not decrease. The data suggests that the outdoor environment did something the standard sports field did not: it helped students build a stronger ability to keep going while simultaneously reducing the risk of their exercise becoming an unhealthy compulsion.
The researchers also looked at how these changes were connected. In the outdoor group, the students who increased their persistence were the same ones who saw a drop in their addiction risk. This suggests that in nature, the kind of hard work required to climb a mountain or navigate a forest feels different; it builds a healthy form of determination rather than a rigid obsession. However, in the traditional sports group, the connection was different. There, a stronger interest in the activity was actually linked to a slight increase in addiction risk. This implies that in a highly controlled environment with fixed rules, loving the game too much might sometimes push a student toward an unhealthy attachment, whereas in the wild, that same effort leads to a more balanced state of mind.
The study also noted a small difference between men and women in the outdoor group. Female students in the natural setting showed a greater increase in their long-term interest consistency than their male classmates, meaning they developed a more stable, lasting passion for the activity. No such difference was found in the traditional sports classes. While the changes in grit were modest, the reduction in exercise addiction risk in the outdoor group was the most significant finding. The authors conclude that the location of a physical education course is not just a neutral background. It is an active force that shapes whether students learn to persevere in a healthy way or fall into the trap of compulsive behavior. The study suggests that bringing physical education out of the gym and into the wild may offer a unique path to building character without the psychological costs that sometimes come with highly structured sports.
