This topic is interesting because it is an example of physics in
the real world.
On the other hand, kinesiology is a contender for the the world's
most useless baccalaureate degree.
It's complicated, because:
A) There are lots of jobs for kinesiologists. Every sports team
and every hospital has kinesiologists and exercise physiologists
A good kinesiologist can accomplish great things. Sports shoes
have improved dramatically in recent years. Also gymnastic mats.
And sport techniques.
B) On the other hand, supply exceeds demand. Lots of kids want
to grow up to be Michael Jordan, so they concentrate on sports
in school, and they major in "kinesiology" because the have to
major in something. Then they find that they can't get a job
as a player /or/ as a trainer.
Doing it right is really hard. In HS you study the motion of
a point particle, and in introductory college courses you
study the motion of a rigid body ... but now we are talking
about something with a whole lot of moving parts. Just doing
the motion capture properly is really hard.
So: *Good* jobs in kinesiology are scarce. Like almost anything
worth doing nowadays, it's interdisciplinary. You need to know
about sports, and you need to know about physics. A lot of physics.
Also computers. It's not quantum chromodynamics, and it's not
relativistic fluid mechanics, but it's still awfully complicated.
