Lately this came to my head: Lets take the workout Fran - comparing 2 times of 2 different athletes doing the workout RX and both mechanically perfect executed, one finishing at 6:00 and the other one at 3:00. Given the weight and the pullups, the one finishing at 3:00 should have much higher power output, mathematically. And power output is directly linked to intensity. However, if we asked an athlete to do Fran very very slow in the movements, not by taking long breaks but by doing every single thruster and pullup SLOWLY (eccentric/concentric) the muscle breakdown would be much much higher than the "dynamic" and fast Fran executions although it would take lets say 15:00. So my question is, wether muscle breakdown and from that the effect of hypertrophy and adaption is linked to intensity and power output.
