World Athletics chief say rules will uphold the integrity of women’s sport amid debate over inclusion of trans athletes.

World Athletics president Sebastian Coe says the track and field’s governing body has approved the introduction of cheek swabs and dry blood-spot tests for female athletes in order to maintain “the integrity of competition.

World Athletics President Sebastian Coe said the testing plan is “not just talking about the integrity of female, women’s sport but actually guaranteeing it.”
