I walk by small parks today and rarely see kids playing vigorously. This is not right. Parents must arrange their schedules in such away as to provide preteen children two hours in the morning when notin school and ideally an additional two hours in the evening all forplaying on the park's hardware.
For the parent involved, this is a great time to read and use othermedia and all that.
Kids are programmed to run off their surplus energy and it iscritical to organize their lives to take advantage of that. I recallmy young daughter developing real calluses on her hand because sheworked the monkey bars so hard. As described, two two hour sessionsare needed.

Children need aminimum of seven minutes a day of vigorous physical activity,demonstrates recently published findings by University of Albertamedical researchers and their colleagues across Canada.
"If you watchlate-night television, or look in the backs of magazines, you'll seemagical ads saying you need just 10 minutes a day or five minutes aday of exercise to stay fit. And for those of us in the medicalfield, we just rolled our eyes at that. But surprisingly, they mayactually be right and that's what this research shows," saysco-principal investigator Richard Lewanczuk, a researcher with theFaculty of Medicine and Dentistry at the U of A.
"Our researchshowed children don't need a lot of intense physical activity to getthe health benefits of exercise - seven minutes or more of vigorousphysical activity was all that was required. But the seven minuteshad to be intense to prevent weight gain, obesity and its adversehealth consequences. And most kids weren't getting that."
Lewanczuk worked onthis study with Jonathan McGavock, his co-principal investigator andformer post-doctoral fellow, who now works with the ManitobaInstitute of Child Health. They collaborated with Black Gold RegionalSchools in Leduc and surrounding communities just south of Edmonton,as well as researchers from the University of Manitoba, Queen'sUniversity, the University of Newcastle, and U of A researchers fromthe Faculty of Medicine and Dentistry, the School of Public Health,Physical Education and Recreation, and Agricultural, Life andEnvironmental Sciences. The team's findings were recently publishedin the peer-reviewed journal Archives of Pediatrics and AdolescentMedicine.
More than 600children, between the ages of nine to 17 from Leduc and surroundingareas, wore monitors that tracked their physical activity levels forseven days. These children also had their weight, waist circumferenceand blood pressure regularly monitored.
Researchers reviewedthe data collected through the Healthy Hearts program via Black GoldRegional Schools and determined the children spent almost 70 per centof their time doing sedentary activities; nearly 23 per cent wasdevoted to light physical activity; almost seven per cent to moderatephysical activity and 0.6 per cent to vigorous physical activity.
Overall, boys wereless sedentary than girls. And the more vigorous the physicalactivity, the less apt the children were to be overweight. Childrenwho were overweight had improved fitness levels and shrinking waistlines when they increased the amount of time spent doing vigorousactivities.
Lewanczuk said theteam made some other notable findings including the following: thereweren't the expected health benefits from doing only mild or moderateactivity even if the time spent doing this type of activityincreased. What seemed to be critical was taking part in intensephysical activity. For kids who took part in vigorous physicalactivity that lasted longer than seven minutes, their health benefitswere significantly better. And the whole notion of being overweightbut fit? The team's data didn't support that finding in children. Ifchildren were overweight, they were also unhealthy, Lewanczuk says.
"This researchtells us that a brisk walk isn't good enough," says Lewanczuk, aprofessor in the Department of Medicine who has been studying thistopic for eight years. "Kids have to get out and do ahigh-intensity activity in addition to maintaining a background ofmild to moderate activity. There's a strong correlation betweenobesity, fitness and activity. Activity and fitness is linked to areduction in obesity and good health outcomes."
Getting young childrento make vigorous physical activity part of their daily routines isimportant, especially considering activity levels in the teenageyears drop right off, Lewanczuk says. And previously publishedresearch from the same group of children shows kids are more activeat school than they are at home.
"Quite often theactivity levels on evenings or weekends would be almost flat,"he says. "We made the presumption that kids were just sitting infront of a screen the whole time."Lewanczuk hopes theresearch findings will help schools decide what type of mandatoryphysical activity is needed.
He praised the schooldistrict involved in the study, noting the research wouldn't havebeen possible without its support.
Paul Wozny with BlackGold Regional Schools said physical activity is always worthwhile andnoted that increased moderate to intense activity was closelyassociated with lower weights from year to year. He said the HealthyHearts project has truly created "a school and community culturewhere regular physical activity and healthy nutrition are seen asessential ingredients for students' health, wellness and life-longlearning. Everyone is involved - students, their parents, teachers,staff, researchers and the community as a whole.
"We are alwaysstriving to improve, so we regularly review the research results tohelp us fine tune and develop future activity and wellnessprogramming at all of our school communities. Black Gold RegionalSchools' Health Hearts project has received both national andinternational recognition as a world-leading school and communityinitiative dedicated to the improvement of student cardiovascularhealth through regular physical activity and multi-stakeholdersupport."
The primary funders ofthe research were: the Canadian Diabetes Association and the AlbertaCentre for Child, Family and Community Research.
"The CanadianDiabetes Association is proud to be a leading supporter of diabetesresearch in Canada, investing more than $7 million annually indiabetes research," said Janet Hux, chief scientific advisor forthe Canadian Diabetes Association. "The association encouragesCanadians to pursue healthy lifestyles in order to prevent and managediabetes. Dr. Lewanczuk's work provides important new insights thatmay make enhanced activity more feasible for children and youth."
The Alberta Centre forChild, Family and Community Research added: "Having this kind ofevidence should make it easier for parents, schools and daycareprograms to do activities with children that will help developlifelong healthy attitudes towards exercise and activity,"stated Alberta Centre for Child, Family and Community ResearchPresident and CEO, Robyn Blackadar.
