Of course It depend on who they did the research in what condition. It also depend on the period of the year. Those percentages are just guidelines…Not GOD on piece of paper…
Some authors would break down alactic into power/capacity and lactic into power/capacity and also 3-4 aerobic stages. There are many ways to complicate everything…
We can also add another system that would be completely off chart, we would call It neural pulse/reaction start 0,2-0,4s. But many authors can include It In the anaerobic power or anaerobic alactic power.
Oh well, there is a running gag between me and some of my friends in University. In many times, University serve no other propose than to complicate simple issues with many words & endless discussions when simple guidelines and intuitive interpretation of the reality we have in front of us is what we really need.
Thanks for the implication of some great coach here. Maybe that’s why Poliquin says that physiologist/scientist are always left 15-20years behind. PARALYSIS BY ANALYSIS
