This isn't scientific proof. It is a few theories that you've grabbed from magazines to prove your own theory. One study isn't scientific proof. To say that men are more fit for freestyle skiing completely buys into the worst of 14 year olds on newschoolers who have nothing better to do than hate on girls because, well, girls don't like them. In most sports, females aren't competing against men so we need to cheer for the female freeskiers rather than hating on them because we need female heroes. We need to demand more consistent judging for them so that the females who are not spinning like figure skaters (arms tucked into their chest) or flipping like aerialists are rewarded. Female freeskiers need to get into the gym year-round so they have stronger/bigger thighs, butts, shoulders, core muscles. Nothing is a guarantee against injuries but too many of the females just aren't strong enough but they could be. Female freeskiers need to stop hucking that one big trick to get attention but rather train so they can bring bigger tricks into competition and filming.
