I'm not quite sure what you mean by intensity (sorry if I'm uneducated). Also, what I was doing before, what would it be useful for (the 45-1m of sprinting with 15s of jogging and repeat).
intensity for treadmill would be incline. intensity for eliptical would be resistance. intensity for exercise bike would be resistance.
intensity doesn't apply to normal jogging or swimming or any other exercise which is performed off of a machine
what you were doing before is for pure cardiovascular anaerobic and VO2 max training. This would basically be in preparation for extreme sprinting or total endurance environments where bursts of speed are necessary. For fat loss, this is not the way the go.
