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 announced the decision following a council meeting at the World Indoor Championships in India. Under the new protocol, all female athletes would have to undergo a one-time cotton swab or dried spot blood test in order to compete in World Athletics competitions.

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.”
