The present study provides newinformation regarding the impact of
aerobic exercise on obese adolescents' energy balance. As highlighted
by Caudwell, Hopkins, King, Stubbs and Blundell [4] in obese adults
[4], physical activity alone might not be enough to induce weight loss
in obese adolescents, depending on their individual energy intake response
and certainly mainly on their tendency to reduce their physical
activity level outside the prescribed sessions. Looking at such results,
it seems necessary to consider the impact of physical activity on both
sides of the energy balance (expenditure and intake) equation during
and outside the exercise hours, to obtain a better understanding of
which participants lose weight in response to structured aerobic exercise.
Future research should be conducted to clearly and objectively explore
both the nutritional and energetic adaptations to a physical
activity program (depending on the program's characteristics such as
duration, and intensity) in obese youth providing then important results
to optimize our weight loss strategies and identify which participants
would benefit most from exercise intervention.
