A recent study conducted in Britain found that physical exercise programs for children have negligible impact on their total activity and thus on weight loss itself.
"Physical activity interventions are not increasing physical activity sufficiently to impact on the body mass or body fat of children. It is in everyone's interest to find something that works effectively," said lead researcher Brad Metcalf.
Other experts have not agreed with this point of view and have said that such programs should not be dismissed as ineffective.
School environments should educate and encourage children and teens on the importance of exercise and physical activity in ways that make a difference to their lives.
