Playing 10 minutes daily helps kids cut diabetes risk in adult life

Health Desk-- 29 March, 2017:  Just 10 minutes of playing every day can reduce a child's risk of having heart disease, developing heart disease, or suffering a stroke later in life, a new study says.

According to scientists, replacing light-intensity physical activity with brief periods of vigorous exercise may provide significant cardiometabolic benefits in kids - particularly those with large waist measurements and elevated insulin levels in their blood.

"The results suggest that substituting modest amounts of vigorous physical activity for longer-duration light exercise may have cardiometabolic benefits above and beyond those conveyed by moderate activity," said lead author Dr. Justin Moore.

"But as vigorous activity was independently associated with only two of the markers examined, it may be that its truly meaningful benefits may be limited, relative to less-intense exercise," Moore added.

The study, conducted at Wake Forest University in North Carolina, analyzed data from more than 11,000 kids between ages four and 18, who were included in 11  international studies in the US, Brazil and European countries.

The researchers focussed on records that included the child's age, gender, level of physical activity and at least one biomarker - a measurable indicator of a medical state or condition - of cardiometabolic risk.

Such indicators included weight circumference, blood pressure, and bloodstream levels of 'good' cholesterol, 'bad' cholesterol, triglycerides, glucose and insulin.

Researchers found 32 significant associations between biomarkers and vigorous physical activity out of a possible 360.

'All-out' workouts adding up to just 60 seconds within a ten minute session were shown to improve insulin sensitivity and c ardiorespiratory fitness.

"If such studies provide robust results, a relatively brief but intense dose of physical activity - perhaps as little as 10 minutes day, which is certainly feasible for most youth - could turn out to be part of a "prescription" for children to achieve or maintain cardiac and metabolic health,' he added.
