Replying to HELP ME OUT

Hey guys, so I have this school project for exercise science where we pick a sport and have to relate it to each unit we studied and I obviously chose freestyle skiing.

It's for our grade 12 ISU and it has to be minimum 250 pages. Holy flippin cow, like why torture us. anyway, If you guys have any info about how freestyle skiing relates to the body, can you please comment a link, bibliographies,pictures, essays, extra info, or anything that'll help fill out 250 pages.

If you're actually up for this (which I don't blame you if you aren't)... some of the units we learned were:
-Anatomy and physiology
-human performance
-evolution of sport
-social issues in sport

PLEASE HELP A FELLOW NON MOTIVATED STUDENT OUT.

Thanks peeps.
