The Claim
In non-athlete transgender women who have undergone long-term gender-affirming hormone therapy (average 14.4 years) following male puberty, absolute maximal oxygen consumption (VO2peak) during physical exertion is higher than in cisgender women and lower than in cisgender men, indicating an intermediate cardiopulmonary capacity when not adjusted for body composition.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Trans women who've been on hormone therapy for years can take in more oxygen during intense exercise than cis women, but less than cis men — putting their heart and lung fitness somewhere in the middle.
See the scientific wording
In non-athlete transgender women who have undergone long-term gender-affirming hormone therapy (average 14.4 years) after prior exposure to male puberty, absolute maximal oxygen consumption (VO2peak) during physical exertion is higher than in cisgender women (2606±416.9 ml/min vs 2167±408.8 ml/min, p<0.05) and lower than in cisgender men (3358±436.3 ml/min, p<0.0001), indicating an intermediate cardiopulmonary capacity when not adjusted for body composition.
What the research says
1 studyThe study found that transgender women who took hormone therapy for many years use more oxygen during exercise than cisgender women but less than cisgender men, which matches the claim.
