The idea of this is to get the muscle to contract and relax very quickly, changing between an eccentric and a concentric contraction as quickly as possible. It looked like something someone would do to garner attention on social media and this was before the modern scourge of clout chasing with wacky exercises.īut looking into the contract-relax relationship it started to make much more sense.

When I first saw oscillatory work, I was utterly perplexed. One of the tools I implement, have tinkered with, and been exploring for some time are oscillatory type movements. The bridge of transfer for them is less clear. But here’s the thing, maybe 20% of the athletes I work with are field athletes. The question of weight room speed is a hot one, with higher velocity barbell exercises giving way to ballistic and plyometric, or in the case of the field athlete giving way to sprinting and COD drills. This probably makes up maybe 5% or less of my approach which for the most part, is meat and potatoes style strength and conditioning. It represents a lot of tinkering on Cal Dietz part, I have run with it and adapted it, to make it work with my athletes. This type of training is probably at the edge of what is pragmatic and justifiable based on our understanding of current research. The idea is much like isometrics, it is used to improve strength, power, or speed qualities at specific joint angles. This method can be used during any block but it’s mainly used during peaking blocks. I was first introduced to oscillatory work as a peaking method through Cal Dietz’s triphasic training. Oscillatory training covers 3 similar yet slightly different methods, oscillatory training, Antagonistically Facilitated Shock Method (AFSM) method and Reflexive Trimetric Method (RTM)
