Can the answer be drug testing?
Seiler and Sailer then focus on the factor which they believe is most responsible for the 'decline of female athletes' - drug testing! As they point out, random, surprise drug checks were introduced into the world of track and field in 1989, 'at least partly in response to the embarrassment of the Ben Johnson case in the 1988 Olympics'. Drug use, say Seiler and Sailer, benefits females more than males; therefore its supposed abolition as a result or random testing has hurt elite female performances far more than those of their male counterparts.
