Swimming in controversy
C
ollegeswimmingisfarfromthemost
talkedabout sport in America. But this
year’s National Collegiate Athletic Associa
tion (ncaa) Women’s Swimming and Div
ing Championships, which take place be
tween March 16th and 19th in Atlanta, have
attracted unusual attention. Most of it has
been focused on a single athlete: Lia Thom
as, from the University of Pennsylvania.
Ms Thomas has already broken records
in previous competitions. In December she
won a 1,650yard freestyle race by 38 sec
onds. On that kind of form, in Atlanta Ms
Thomas was expected to win comfortably.
But not without controversy. For al
though Ms Thomas identifies herself as a
woman, biologically she is a male. Her
dominant performances have thrust her
into the centre of the debate around
whether transgender women—males who,
like Ms Thomas, identify as women—
should be allowed to compete in women’s
sport. It is an argument that is increasingly
splitting sport, in America and beyond.
The argument is playing out inside sta
diums, newspapers and state legislatures.
At past events, some in the crowd have re
fused to applaud Ms Thomas’s victories,
waiting for the secondplace swimmer to
finish before cheering. In February a letter
by 16 of Ms Thomas’s teammates was sup
portive of her new identity, but said that
“biologically Lia holds an unfair advanta
ge...in the women’s category.” (Citing fears
about future employment, none was will

published on March 15th and signed by
more than 5,000 people—including many
Olympic athletes—took a similar view.
On March 3rd Iowa became the 11th state
to pass a law forbidding trans women from
competing in women’s sports (others in
clude Texas and Florida). Such rules have,
in turn, prompted lawsuits attempting to
get them overturned. Big national non
profit organisations, including glaadand
the American Civil Liberties Union, sup
port Ms Thomas competing in the wom
en’s category. (A third letter, this time
signed by 300 athletes, likewise supported
Ms Thomas.) The argument ranges far be
yond swimming, too, covering cycling,
highschool athletics and even weightlift
ing. In 2021 usaPowerlifting, a weightlift
ing organisation, was sued over its policy
that athletes should compete on the basis
of their sex, not gender identity.
Testosterone-driven
Ms Thomas is breaking no rules. For many
years the ncaa’s policy was that trans
women athletes could compete so long as
they took medication designed to suppress
their testosterone levels. Testosterone is
the main male sex hormone and a potent
anabolic steroid. Levels surge during pu
berty, which is the main reason why adult
males outperform females in almost every
sport. In swimming the women’s world re
cord for the 400metre freestyle, for in
stance, stands at three minutes and 56 sec
onds. The men’s record is 3:40. In some
sports the gap is much larger. The Ameri
can men’s combined powerlifting record is
1,296kg. The women’s record is 793kg.
The hope was that suppressing testos
terone levels would reduce those advan
tages, letting female athletes compete with
trans women on a reasonably level playing
field. The science suggests that the com
promise does not work. A pair of review
studies, published in 2020 and 2021, con
cluded that testosterone suppression does
not go far in removing the advantage be
stowed by male puberty.
America’s swimming authorities are
split. Having originally said it would fol
low the lead of usaSwimming, which gov
erns elite swimming in America, the ncaa
changed its mind in February when usa
Swimming passed new, more restrictive
rules that require trans women to prove
that “prior physical development” had not
given them a competitive advantage.
The issue is just as contentious outside
America. In September a group of British
sporting bodies concluded that balancing
fair competition and the inclusion of trans
women in women’s sport is impossible; in
dividual sports would have to decide
which was more important. Some of them,
such as British Triathlon, welcomed the
guidance. Others, such as the British Kick
boxing Council, seemed less keen. (As with
Ms Thomas’s teammates, the report found
that few elite female athletes were willing
to speak publicly about the topic, lest they
lose sponsorship deals or team places.)
In 2020 World Rugby decided that trans
women would not be allowed into the
women’s game on grounds of both fairness
and safety. But its remit extends only to in
ternational matches, and most domestic
unions have the opposite policy. In Den
mark, sports authorities have recommend
ed that trans women be barred from wom
en’s sport at the elite level. The result, says
Ross Tucker, a South African sports scien
tist who was involved with the World Rug
by decision, is a patchwork. Male athletes
can compete against female ones in some
sports, in some countries, and at some lev
els—but not others.
In the short term, that seems unlikely to
change. Many sports take their lead from
the International Olympic Committee. Be
fore the Tokyo games last year, it had re
quired transwomen athletes to suppress
their testosterone levels. However, in the
light of the scientific evidence, it promised
new rules. Its new policy, announced in
November, was greeted with bafflement. It
threw the hot potato back to individual
sports, but warned them, despite what the
recordbooks say, that there should be no
automatic assumption that males possess
any advantageatall.Clarity seems further
away than ever.n
