Hi Armando, I am curious to know what is behind determining how much MPA should be drained in a particular interval and how many times should you do it in a workout. How to optimize the design to get the maximum benefit. In other words, how far down should you take it during the interval and how far back up on the recovery. Is there something on the blog you can point me to?
There really isn’t a set of best practices established to that detail but I can say that Difficulty Rating does appear to be a factor in interval design. If the repetitions are too deep and too frequent, rating goes very high which will suggest it will more likely to cause the athlete to abandon. Ultimately strain is what needs to be applied and in the right allocation ratios of low/high/peak. Balance all these in the design of your workout toward your goal.
