Just 7 Minutes a Day...
Recent research published in the Archives of Pediatrics and Adolescent Medicine looked at the physical activity levels of 600 Canadian children ages 9-17. The research indicated that children needed at least 7 minutes per day of vigorous physical activity to prevent weight gain and obesity.
The data indicated that the children spent 70% of their time doing sedentary activities, nearly 23% was light physical activity, almost 7% was moderate physical activity and 0.6% was vigorous physical activity. The more vigorous the physical activity was the less likely children were overweight.
The researchers also determined that the expected health benefits of mild to moderate physical activity were not observed. The key component was participating in vigorous physical activity.
