Our results showed no differences in absolute strength between transgender
women and CM and no difference in relative handgrip between
any of the groups in this study (figure 3). These results high-
light the differences between athlete and sedentary populations.
However, the results relative to hand size also concur with the
notion that greater handgrip strength is caused by greater hand
size,42 as there were no differences in results between the four
groups when normalised for hand size (figure 3C,D). There-
fore, investigations with more accurate measures of strength are
warranted in transgender athletes.
Body composition measures (fat mass
% and fat-free mass %, table 2) between transgender women
and cisgender women found no difference. However, trans-
gender women are, on average as a cohort taller and heavier.
CONCLUSIONS
This research compares transgender male and transgender
female athletes to their cisgender counterparts. Compared with
cisgender women, transgender women have decreased lung
function, increasing their work in breathing. Regardless of fat-
free mass distribution, transgender women performed worse
on the countermovement jump than cisgender women and
CM. Although transgender women have comparable absolute
V̇O2
max values to cisgender women, when normalised for body
weight, transgender women’s cardiovascular fitness is lower than
CM and women. Therefore, this research shows the potential
complexity of transgender athlete physiology and its effects on
the laboratory measures of physical performance. A long-term
longitudinal study is needed to confirm whether these findings
are directly related to gender-affirming hormone therapy owing
to the study’s shortcomings, particularly its cross-sectional design
and limited sample size, which make confirming the causal effect
of gender-affirmative care on sports performance problematic.
The cited article finds that, /after adjusting for body size,/ trans women have comparable strength to cis women, and inferior performance in the other measured metrics. In other words, they found that taller people have more muscle mass and are stronger because they are taller.
