“ We now know what intensity level of strength training it takes to activate the BAG3 system, so we can optimize training programs for top athletes and help physical therapy patients build muscle better”
From skimming the article and papers it references, the suggestion is that the higher the intensity (which seems to be rate of contraction of skeletal muscle rather than heart rate or respiration rate etc) the stronger the effect.
However, this assumption seems based on mouse experiments.
They aren't identical to just doing 10 regular sets, but perhaps something like pyramid sets or circuit training would be similar enough to produce the same effect?

This makes it sound like apoptosis.
