What are they arguing about ice-skating? Ice-skating is largely marked according to multi-rotational jump sequences and more men can consistently quad jump than women. The majority of "women" who can do quad jumps, especially in sequences are in reality very, very underweight Russian teenage girls. Trained to use pre-rotated jumps that absolutely destroy their physical health by causing permanent bone and joint damage. Along with the damage of caused by maintaining ridiculously low levels of body fat and almost certainly taking puberty blockers to delay changes to their hips and breasts. Often these women have limited mobility, compared to non-athletes, before their 20th birthday.

Ice-skating is a potentially beautiful sport but healthy, adult women can't do the kind of quad sequences that men and teenagers can, because if you have fully developed bones, organs and adult body fat levels, you need male strength to lift yourself that high, for that long. Although as rotations increased last year with the first successful quad axel in competition, it will be interesting to see if fully developed men can keep up, as the jump is being done by a teenage boy. We can see in sports using similar physics for rotational jumps, like skateboarding, that speed and height for multi-rotation often peaks in childhood, sometimes for males as well as females.
