The Effect of Academic Self-Efficacy in Physical Education on Exercise Adherence among Middle School Students: The Mediating Role of Exercise Self-Regulation
This study of 684 middle school students reveals that academic self-efficacy in physical education positively predicts exercise adherence, a relationship that is partially mediated by exercise self-regulation.

Imagine your brain is a supercomputer running a massive game called "Life." Sometimes, the game gets tough. You might face a boss level called "Homework Mountain" or a glitch called "I'm too tired to move." In the world of sports science, researchers are always trying to figure out why some players keep running the game even when it gets hard, while others just pause the menu and walk away. This particular study zooms in on a specific part of the game: the "Physical Education" (PE) classroom. It asks a simple but powerful question: Does feeling like you're good at the PE class itself make you more likely to keep exercising when you're not in school? To understand this, we need to know three things. First, Academic Self-Efficacy is just a fancy way of saying, "I believe I can do this specific school task." In this case, it's believing you can master a basketball layup or run a mile in PE. Second, Exercise Self-Regulation is your internal coach. It's the ability to set a goal, make a plan, and stick to it even when you'd rather watch TV. Third, Exercise Adherence is simply the act of showing up and playing the game over and over again, not just once. If you can keep the game running, you stay healthy and fit.
So, what did the researchers actually do? They gathered 684 middle school students from six different schools in J Province and asked them to fill out a survey. They wanted to see if the "I can do it" feeling in PE class (Academic Self-Efficacy) was the secret sauce that helped students keep exercising on their own time (Exercise Adherence). They also wondered if there was a middleman in the story—something that connected the classroom confidence to the real-world running. That middleman turned out to be the "internal coach" (Exercise Self-Regulation).
Here is the story they found: The students generally felt pretty good about their PE skills and were decent at sticking to their exercise plans. But the data showed a clear pattern. Students who felt confident in their PE abilities were much more likely to keep exercising outside of school. However, it wasn't just a direct magic spell. The study suggests that feeling confident in PE helps students become better at being their own coaches. When you believe you can master a difficult move in class, you get better at setting goals, planning your time, and pushing through the "I'm too busy" excuses later in the day.
The researchers tested this by looking at the numbers. They found that for every step up in PE confidence, there was a significant boost in the ability to regulate exercise, which in turn boosted the actual habit of exercising. In fact, the "internal coach" (self-regulation) explained almost half of the connection between feeling good in PE and actually sticking to a workout routine. It's like saying that believing you can win the PE class doesn't just make you run faster; it teaches you how to train so you keep running even when the bell rings and you leave the gym.
The study also looked at who was doing the best. Boys, students who already exercised a lot (four or more times a week), and those who were part of sports clubs scored higher on confidence, self-control, and sticking to their habits. Interestingly, older high school students were a bit less likely to stick to their exercise than younger middle schoolers, likely because the pressure of big exams gets in the way. But no matter who they were, the main rule held true: if you feel capable in your PE class, you are more likely to keep moving.
The authors suggest that this isn't just about forcing kids to run more laps. Instead, it's about how teachers can build that "I can do it" feeling. By giving tasks that are just right—not too easy, not impossible—and by cheering on small wins, teachers can help students build that internal coach. When a student leaves PE class thinking, "I can handle this," they are more likely to take that same confidence and use it to plan a run, a bike ride, or a game of basketball when they are home. The study suggests that the PE classroom is a training ground not just for muscles, but for the mental habits that keep people active for a lifetime.
