As students become adults, and are faced with the advice to 'get some exercise' to avoid diabetes, heart disease, obesity and other conditions, they need to have good answers to the following questions: How? What? When? Where? and Why? Primary, secondary and tertiary physical education programs will give them some answers to these difficult questions.

Re: Phys-ed doesn't cut obesity, study finds (March 31). As the national voice of physical activity and sport participation in Canada, ParticipACTION agrees that obesity is a complex issue. Physical activity levels are but one contributor to body weight, and school-based programs are but one means to impact physical activity levels in our children.
As outlined in the 2008 Active Healthy Kids Canada Report Card, there are a whole host of factors that impact how active and healthy Canadian kids are. School programs, family role models and hours spent watching television are all important parts of the equation. Our children are spending an average of six hours a day in front of a screen and it's clear that schools can't fix this imbalance alone.
Too much emphasis on body weight may be confusing the real message, that physical activity -- independent of body weight -- is essential for overall health and well-being. Physical activity impacts quality of life, social relationships and plays a pivotal role in preventing chronic diseases, such as diabetes, heart disease and cancer.

The article claiming phys-ed doesn't cut obesity (March 31) uses Body Mass Index data to support this conclusion. BMI is a simple ratio of height and weight. It is a really poor indicator of what that weight is made up of. Muscle has twice the density of fat and dramatically skews BMI data. BMI classifies many athletes as obese. I'm not sure what BMI is good for, but it isn't for indicating whether phys-ed is a good idea for kids. That's what the Common Sense Index is for.
