I cannot claim to be able to specifically answer your question, partly because I have never heard this theory. That said, I have noticed a clear relationship between physical fitness (activity) and academic achievement in the students that I teach. I have always thought that it must be something to do with the fact that such students seem to have an ability to prioritise different and seemingly unrelated activities, and consequently, that they come to their various tasks with more specific focus.
You can benefit from the two different approaches based on self-regulation research.
1) The simpler argument is that individuals with high self-regulation are found to have better academic performance, and also better health.
2) Another approach within the self-regulation research is based on "embodied cognitions". This approach has found that by flexing physical muscles, people can improve their self-control. Improved self-control, in turn, is related to better academic performance.

The reference list is quite helpful for the research, As I have been doing QUALITATIVE research on the same topic. I had been reading a lot of literature as well.
But, I am not getting any clue on the THEORY related to the topic to infuse in my research. @Syed Ali
Research shows a strong relationship between physical fitness and academic achievement, as physical activity positively impacts students' cognitive abilities and mental performance. Exercise improves blood flow to the brain, enhancing concentration, attention, and problem-solving skills. Additionally, physical activity helps reduce stress and anxiety, creating a mental state more conducive to learning.
Physiologically, physical fitness contributes to better cardiovascular health, which increases the brain’s ability to function efficiently. Regular exercise also stimulates the release of chemicals such as dopamine and serotonin, which play a role in improving mood and motivation, ultimately reflecting positively on academic performance.
Moreover, studies indicate that students who participate in sports activities tend to develop time management and self-discipline skills, which are crucial for academic success. Engaging in sports also boosts self-confidence and fosters a healthy competitive spirit, driving students to perform better in their studies.
Therefore, physical fitness can be considered a key factor in enhancing academic performance. Schools should encourage integrating physical activity into students' daily schedules, whether through physical education classes or other movement-based activities.
