Why does it seems that children usually have a much greater physical disposition/stamina than the average adults?

Question

I mean specifically for very young children such as toddlers. It seems that, as a rule of thumb, they are much more physically motivante than the average (say, 30 years old or so) adults, barring those who actually practice regular exercise. Some children seem like they can run, climb and jump with a consistent timing for longer than many adults.

Is it because our own disposition has been ruined by a generally sedentary lifestyle?

I think you answered most of your own question by excluding “those who actually practice regular exercise”.

The average kid has better cardio than your average adult who doesn’t exercise. But if you pit a child against an adult with decent cardio, that adult is gonna have way more endurance than the kid. As can be seen often on a hiking trail when the kid inevitably ends up on their parent’s shoulders.
