 So there are minimum guidelines that are established for activity, and I just explained to you that adults should accumulate at least 30 minutes of brisk walking on each day, right? And youth, children and adolescents should accumulate at least 60 minutes of moderate to vigorous physical activity. The kinds of activities that might make you get warm and sweat and breathe hard, and we don't even come close. So 85% of adults and 93% of youth don't meet these guidelines. And these data are Canadian data, and they don't come from, this isn't a small sample, this is a random sample of about 3,000 adults and 16,000 children and adolescents, using the best data we have, or best tools we have to measure activity. So it's a little bit frightening. If we take a closer look at the average Canadian adults' daily activity, what we find is we accumulate about 5% or 5% of our time is spent in health enhancing physical activity, this moderate to vigorous physical activity. We spend about 25% of our time in light activity, and we're sedentary for 70% of our waking hours. So again, the movement movement, right? And if we take a look across the lifespan, some important data are revealed, or some patterns. So on the x-axis, there's the age groupings, and the blue bars are males, and the red bars are females. And on the y-axis, that's health enhancing physical activity, or minutes of moderate to vigorous physical activity. So what I want you to notice there is that as children move into adolescence, there's a very large precipitous decline in physical activity. By the time youth reach their 20s, and most adults, we get less than 10 minutes a day of health enhancing physical activity. Less than 10 minutes a day. So I grew up in the times before the iPad and so on and so forth, and I would go to the library and go through the card collection and pick up the one. We don't do that anymore, and these great time and labor-saving devices that we call efficiencies have pretty much decimated our daily activity levels. Ironically, these technologies promised us more time and less labor, but what really has happened is I think they've made us busier people with less time. I think they've limited our sensory experiences, and I think they've negatively impacted our health. I think the data suggests that not only our physical health, but our mental health. The latest data, 2009, currently in over half of the United States, one in four adults is obese, and these kind of data aren't available on Canadians, but based on the research, the trends are somewhat similar. Now, youth are the least overweight and most active. I want to make that clear because I hear a lot of people, they say, kids, all they do is watch TV, but they don't. But childhood obesity is a major concern because 50% of obese kids, children, become obese adults. 70% of obese adolescents become obese adults, and having obese parents increases that risk. And the important thing here is that, particularly for you, children don't have control over their own environments. And so parents and schools are major determinants of children's health, major determinants. And so the question is, how will you or how will we and teachers get kids off to a healthy start? And in schools, numeracy and literacy are the major foci, right? But I think we need to give some attention to physical literacy because the kids need it. And there's a movement among physical educators and coaching communities and our school healthy schools people to get kids moving and build this physical literacy. So for me, I've been studying and practicing the art and science of human movement for the past 19 years in the following capacity. So I've been a university professor, a scientist researching physical activity and health outcomes on children, adolescents, pregnant women, and cancer patient survivors as a teacher and learner with children, adolescents and adults in movement settings as an exercise physiologist for elite and professional athletes. And if I have to summarize what I've learned over that time in four words, it would be these. Humans need to move, you know, and so you ask why? And that's what this presentation is all about because movement is medicine. Movement is academic and movement is freedom. So what we know, what we know on the mountains of evidence is that physical inactivity leads to obesity, diabetes, hypertension, heart disease, bone and joint problems, cardiovascular disease, cognitive and mental impairments. There's no question about that. And the evidence between physical inactivity and these health outcomes is strong, which means the prevention and the cure to these diseases, the cure to these diseases is physical activity.
