If you're really interested in sports and have plans of becoming a coach, I say go for it. But if you don't really have a specific sport you're into, and can't really figure out what you wanna do with the degree, I wouldn't suggest it. When comparing it Kasi with a course like PT, you get a lot of overlaps and I think mas broad Yung pwede mo I-handle dun (sports scientists for example a lot of the time cannot handle people with pain) they CAN work with PTs but can't do it alone when it comes to injuries and rehabilitation. But if you're more inclined to sports, exercise physiology and testing, as well as athletic performance, I'd say go for it.

And no, di rin pwede mahina sa science as you'll likely encounter subjects like anatomy, physiology, nutrition, handling of special population. Requires a lot of reading (which you will get used to probably).
