If HIIT is truly performed correctly, then HIIT is a more superior version of cardio training over the old slow paced long duration cardio. There may be a need to mix it up and long duration does have it's benefits too, but certainly HIIT has more benefits to someone with an active, athletic lifestyle like prep sports, wrestlers, fights, etc. There's a few reasons for this..

* HIIT is anaerobic, the long duration is aerobic
* Long duration training results in increased aerobic capacity, but with little to no effect on anaerobic capacity
* HIIT on the other hand results in increased anaerobic capacity AND increased aerobic capacity
* Most sports are anaerobic - SAME AS HIIT

So it only makes sense, to achieve more athleticism, HIIT is the way to go
Also, long duration cardio does not train your heart and HIIT does, a major advantage in itself as the heart is most important muscle we got
