Adherence

Moderate-to-vigorous physical activity (MVPA) significantly declines from childhood to adolescence and continues to decline, albeit at a lower rate, into young adulthood, while sedentary time increases substantially during the transition to adolescence.

Physical activity naturally drops as kids grow up, and they sit more, especially during adolescence. To combat this, focus on maintaining activity levels through childhood and early adolescence, as these habits are critical for preventing long-term health risks. In young adulthood, be aware that activity levels may continue to drop, so intentional effort is needed to stay active.
