On guard: girls enjoy duelling work
The survey also found pupils at girls-only schools did not enjoy the same level of activity, with only 65 per cent doing two hours a week.
Participation drops in all schools during the final years. Only 63 per cent of Year 11s and 67 per cent of Year 10s took part in two hours a week.
Schools in the sports partnership at Torbay in Devon, including Paignton Community Sports College (above) have managed to stop girls giving up on sport by running a "body management course" that covers fencing and scuba diving as well as sports bras and haircare.
Sports partnership development manager Tony Callcut said: "We now have girls who carry on the activities outside school, which shows how successful it has been."
