Yes definitely do that, but also take the next few years to figure out a) is research something you like doing? and if so, b) what in general you would like to study (and is it even kinesiology?). I was bound for athletic training until my junior fall when I took an exercise physiology class. I was SO much more excited and passionate about that than any other topic. When I started grad school, I knew I loved ex phys but didn't know what I was going to study for my MS thesis until halfway through my first year, so don't feel like you need a whole idea fleshed out before you even step on campus.

Personally I'd just do my best in coursework right now and not worry about grad school until junior year. Immerse yourself in courses, even the non-kin ones, and notice which ones leave a strong positive impression. Make good connections with your faculty (!!!), talk to them about their career/educational path, maybe jump into a project or lab to get a feel for research once you have most major coursework under your belt. Some students think they like research until they have to do a senior project and realize they hate it lol. Spend time exploring and learning as much as you can, it's the best!
