Ball games may boost bone health in schoolkids

London, Feb. 9: Ball games and circuit strength training may lead to stronger bones, increased muscular strength and improved balance in schoolchildren, according to a major Danish study.

The study, published in the British Journal of Sports Medicine, examined bone and muscle health in 295 schoolchildren from Frederikssund and Copenhagen over a whole school year.

The children participated in the ‘ FIT FIRST’ training concept, which looks into the effects of various types of intense interval training at school.

Researchers compared the effects on children who took the normal school physical education ( PE) classes with children who had intense exercise on the timetable for two hours a week in the form of ball games on small pitches or “circuit training” consisting of gymnastic and strength exercises using their own body weight.

“Our research shows that intense exercise at school has clear positive effects on bone density, muscular strength and balance in 8- 10- year- old children,” said Peter Krustrup, professor at the University of Southern Denmark.

In the children in third grade who played ball games three against three or participated in circuit training for three x 40 minutes a week, muscular strength increased by 10 per cent and balance improved by 15 per cent.

The children’s bone density increased by a whole 45 per cent compared to the control group.

“The study shows that bone density in the ballgame group rose by seven per cent in the legs and by three per cent in the body as a whole, giving a real boost to bone health,” said Malte Nejst Larsen, assistant professor at the University of Southern Denmark.

“Exercise in school for children aged 8- 10 years which improves bone density, muscular strength and balance is the first big step towards preventing osteoporosis later in life,” he said.
