The issue of peaking in MMA is a thorny one and I have seen a number of methods play out. To lift heavy pre fight or not, to focus on speed qualities at high velocities or power based ones. Ultimately it should be determined by the fighter. One of the biggest wake-ups for me was looking into the notion of ‘straining or reactive athletes’ put forward by Cal Dietz. The idea that depending on the sport coach must decide what represents optimal nervous system development. Do you want them to be reactive like a triple jumpers/sprinters or strain like a powerlifter?
