I define medium-pace running as fast running but where you aren't actually going all-out.
Say fast all-out sprinting is what you can hold continuously for less than 2 minutes, and let's say jogging is what you can hold for 10+ minutes. Then medium-pace running is anything you can hold for 2-10 minutes.
Am I correct in saying that there's no need to directly train medium-pace running in football(soccer)?
When does a footballer ever need such a pace? A footballer seems to me to either always be jogging or fast-out sprinting. There doesn't seem to be an "in-between", does there?
I am asking because my friend, who plays football, has this endurance program where he runs 800m or 1200m as fast as he can, and then repeats that a bunch of times.. This fits the definition of medium-pace running as I defined above, and I don't see the point of this training. How does this benefit a footballer? Why not just do regular HIIT where you sprint all-out for 20 seconds, jog for 40, and repeat? Isn't that all a footballer will need?
