I know folks here "substitute" sprinting for other activities such as martial arts, movnat style workouts, etc. However, I would think that if you're not running, you're not running... does that make sense? I have to TRY to get my sprints in because I'm not too motivated to do them. I think sprints work you out in a different way than doing martial arts and other high intensity workouts. Better too for overall fitness I would say.
In my case I work my upper body WAY more than my lower body, so I have to be conscious to do a leg day and a sprint day.
