This illustration synthesizes findings from Fig. 2, detailing the cascade of physical activity types in children. The results suggest that physical activity regimen possibly be effective if typically commences with light-intensity activities, such as standing, gradually advancing towards actions like slow-walking. The gradual progression appears to trigger a cascading effect, facilitating a smoother transition to higher-intensity activities. For example, a child who has previously engaged in a blend of standing, slow-walking, and brisk walking activities will find it simpler to start running than his peer with no physical activity regimen. Bypassing any step in this sequence can disrupt this progression. Notably, while no single activity type has a direct link to BMI, this gradual approach ultimately results in reduced sitting time, thereby mediating a decrease in BMI. The results of the latent profile analysis substantiate this concept, indicating that an elevated overall physical activity duration serves as a protective factor against prolonged sitting time.
