For children and young people, there commended level sof physical activity are much higher than for adults: WHO guidelines recommend children aged 5-17 should spend at least 60minutes daily doing moderate-to-vigorous intensity physical activity, with more intensity and / or greater duration than this providing additional benefits.

• Worldwide, 80% of adolescents aged between 13-15 years do not achieve this target (Hallaletal, 2012). This proportion is even higher across the EU-28–in which 83% of 11-15-year-olds are estimated to be inactive.
• Against these guidelines, the proportions of physically inactive children and young people tend to rise with age, asillustrated in the chart opposite. These data, collected through the Health Behaviour in School-Aged Children(HBSC) survey, show that 15-year- olds are substantially less like ly to meet there commended level soft physical activity than children who are two or four years their junior. Evidence suggests that an increasing prominence of screen-based leisure time in young peoples’lives (e.g.TV, computer, phone, tablet) is taking its toll through increased sedentary behaviour.
• Boys are atenth more likely to be physically active than girls in all countries examined, suggesting that the opportunities presented to young people for undertaking physical activities maybe gender-biased (Currieetal.,2012). – The economic cost of physical inactivity in EuropeAn ISCA / Cebr reportJune 2015.
