Upside Strength – The New Energy System Paradigm Explained (and why you should stop using the old model) : AdvancedFitness

[ad_1]

The old model of the three different energy systems (phosphagen, glycolytic, and oxidative) determining performance at different time domains is wrong. It’s all about oxygen delivery to muscles and how much your muscles can utilize that oxygen. Along with the new model the video also has advice for finding what your energetic limiter is (delivery, respiratory, utilization) so you can specifically target your weakness and autoregulate your training rather than following generic periodization.

Yes it’s legitimate. Check out the youtube description for a link to all the papers.
