Eccentric Overload Efficacy and Guidelines

I have heard that eccentric overload is a particularly potent stimulus for connective tissue adaptaion and can help reduce risk of injury. How much evidence is there for those claims?

Regardless of the efficacy for injury risk reduction I think it will be fun to do some eccentric overload JM press (lower it like a JM press then shift around and BP the bar back up) during my next pivot block.

Any guidelines for eccentric overload training? I am thinking I’ll use a weight far enough beyond my 1rm so that I can do max effort eccentric contractions for 3-4 seconds (maybe that’s ~125%1rm?) for sets of 3-4 (Probably won’t bother trying to use RIR, though I could set it up as failure is a rep less than 3seconds). I haven’t bothered to do any research on reccomendations, sorry if those numbers are absurd.

Little to none when looking at strictly the eccentric. Heavy slow resistance training, by contrast, has good evidence.

I would not do eccentric only overload training for someone looking to maximize strength gains or reduce risk of injury in barbell sports

Good to know. Thanks for the prompt reply doc.
