CHILDREN who exercise for less than an hour a day could be at risk from heart disease in the future, according to Spanish research.

One in seven of the 3,120 children who took part in the Europe-wide study were found to have higher than average blood pressure and cholesterol levels.

The youngsters, aged between two and nine-years-old, were also found to have poor fitness levels and layers of fat, putting them at greater risk of health problems in later life, according to scientists at the University of Zaragoza.

Meanwhile, a separate study by researchers at Newcastle University has revealed that girls exercise for an average of just 17 minutes a day, while boys were active for 24 minutes
