for exact requirements for each school, visit their website. or consult princeton review's Medical School Admissions Guide; nearly every school's reqs are listed there.
in general, they are as follows:
1 year calculus or equivalent
1 year chem or equiv
1 year organic chem
1 year biology
1 year physics
nearly every school demands the associated lab for chem, orgo, phys, and bio.
some also require 1 year english.
a few recommend/highly recommend/suggest: genetics, biochemistry, statistics, maybe others.
but the main ones are: chem, orgo, bio, physics, math.
i have some of the reqs for specific schools; email me with a list of schools, and i'll send you the ones i have.
as far as kines as a major goes, i would highly recommend against it if you are interested in medical school. i got my master's in kines at UT-austin; while there, i TAed a number of courses...they're a waste of time, they're watered down, and you'd be better off majoring in spanish and taking all the sciences as your electives (i know people who do this; dated a history major who did a 125page thesis on the american cancer society which helped her get in med school...well-rounded counts!). spanish is marketable to hospitals/schools.
at least at UT and the few other kines undergrad programs i know of (UGA as well), they're just not worth your time for medical school, because to take the MCAT, you want to learn the concepts you'll be tested on, and kines departments don't usually cover that.
that being said, kines grad programs are typically VERY demanding, so much so that they often (i was told this as i was recruited) avoid kines undergrads and go for science majors. the disparity is disheartening, as a former instructor.
good luck, email if you have questions.
