The Claim
When maximal oxygen consumption (VO2peak) is adjusted for fat-free mass, there is no statistically significant difference between non-athlete transgender women, cisgender women, and cisgender men, indicating that relative cardiopulmonary capacity normalized to lean body mass is similar across these groups despite differences in absolute values.
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.
When you account for muscle mass, trans women, cis women, and cis men have about the same heart and lung fitness level — even if their raw numbers look different.
See the scientific wording
When maximal oxygen consumption (VO2peak) is adjusted for fat-free mass, there is no statistically significant difference between non-athlete transgender women (47.3±5.1 ml/kg/min), cisgender women (53.3±8.3 ml/kg/min), or cisgender men (52.4±5.8 ml/kg/min), indicating that relative cardiopulmonary capacity normalized to lean body mass is similar across these groups despite differences in absolute values.
What the research says
1 studyThe study found that when you adjust fitness levels for lean body mass, transgender women have similar heart and lung performance to cisgender women and men.
