Sorry, what do you mean we know very little about how the body works and processes food? That sounds to me like fields like medicine or physical therapy or nutrition should be impossible, and yet they exist. And correct me if I’m wrong but it doesn’t sound like you know the scope of sports science? It’s a combination of the fields that I made an example of above plus physics, too, and many more (such as business and psychology), but oriented specifically for the purposes of sport and recreation.
