Published this week in the International Journal of Obesity is The Daily Mile's Effectiveness and Cost-Effectiveness for Early Childhood Outcomes and Well-Being: A Randomized Controlled Cluster Test, in which researchers reported the impact of a school year worth a 15 minute BMI.
It's a weird study in that we're talking about 15 minutes of running per day which literally no one should expect to have a significant impact on childhood obesity since both math (15 minutes of running kids, jogging, not even burning calories (single Oreo) and the fact that multiple meta-analyzes have shown that even far more involved initiatives based on PE schools have no impact on childhood obesity.
It's also weird because The Daily Mile is not related to weight,
"The Daily Mile's goal is to improve the physical, social, emotional and mental health and well-being of our children – regardless of age, ability or personal circumstances."
And while it's a problematic study in that it involves the utterly unpredictable non-exciting result, it's the kind of study that can be used as a means of discouraging program continuity.
What could have been studied? What about the Daily Miles impact on marks, concentration, stamina or physical education (note that they tried to do so, but the data collection was too poor to draw many conclusions) or if there was a strong desire to link it to something medical, how to do blood pressure, heart rate recovery, mood, sleep or lipid levels?
As I have said many times, practicing weight management directly changes both the benefits of exercise and the realities of weight management, and we sincerely do so in the name of a program that sees children run an extra 15 minutes a day and at Continuing to see it published in a reputable magazine, he talks about how widespread and dangerous this practice is.
