Students With A Lower Socioeconomic Background Benefit From Daily School Physical Activity

Misleading.

"German school students - especially those with low socioeconomic status (SES) - significantly improved their exercise capacity and body leanness after a year of daily physical activity classes, according to research presented today at the American Heart Association's Scientific Sessions 2009."

Here is the problem.

"'Both BMI average values are in the normal range,' Walther said. 'But children at the higher percentiles are at greater risk of overweight and obesity now and in the future.'"

All the kids started off with normal BMIs.

Not a representation of the greater reality.

The kids most at risk are those whose BMIs are elevated.

This is almost always due to poor caloric intake control.

And since exercise is a terribly inefficient way to control weight compared to controlling Calories in, the study did little, if anything, to make a statement of value.
