I can understand how records for dynamic apnea, or "constant weight with fins" might favor a taller, thinner athlete, and so maybe men might generally perform better.
But for static apnea, the current men's record is 10:12 (Tom Sietas) while the current women's record is 8.00 by Natalia MOLCHANOVA. For no limits using a sled, the current men's record is 214m by Herbert Nitsch, while the current women's record is 160m by Tanya Streeter. These from http://aida-international.org/. For these records, it would seem that external body shape, size, or strength would have little relevance, other than their indirect affect on on things like lung capacity.
So my question is, why don't women equal men in these pursuits?
