Concentric only exercises
-
@JulofEnoch I see! So strength increase is independent of the type of contraction, but eccentric training have the added downside of mimicking stress (no good). And old people likely fall because they lose their reflexes, not strength, so all the more reason to do concentric training and improve mitochondrial / metabolic health.
Very interesting. Thank you for sharing.

@JulofEnoch Dang. I totally fell for that "Ray Peat recovered interview(July 1987 on UofO Student Radio)" link. Well played.

@raypneat One thing to keep in mind is that increased muscle mass is beneficial to a higher metabolism. So its arguably worthwhile to do bodybuilder programs short-term, for instance, to gain muscle mass, and then seek to retain it long-term in more healthy ways for longevity. I'm sure its possible to build muscle mass with concentric-only exercise, but it seems much less straightforward and thus many people may drop out or never pursue it, which is overall a probably worse outcome.

@TexugoDoMel I've followed Peter Attia for a while before discovering Ray Peat, and Attia said something like old people lose their "breaks" i.e. eccentric strength first (following off the stairs as a common cause of death, etc), so it's more important to incorporate eccentric mov't into training. What are your thoughts on this? I'm quite new to Ray Peat and hoping to learn more about how to exercise properly.
I think that for an older person you want to focus (or should) on a stimulus that is strong enough to generate adaptations but weak enough not to cause too much muscle damage, since an old person doesn't have the same metabolic vigor as a young person (for this reason aspirin hinders the gains of a young person but helps the gains of an old person), and that's why the emphasis on the concentric is the most appropriate, even more so if you consider the most current studies that it's not physical movement that causes muscle damage, but that muscle damage is "caused by inflammation" (calcium ion-related fatigue).
I agree with @JulofEnoch that it's more of a reflex thing combined with general muscle weakness. You also don't have to completely eliminate eccentric movements.
@araclavie said in Concentric only exercises:
@TexugoDoMel So training for concentric strength should also lead to gains in eccentric strength as well?
Yes, because in both concentric and eccentric movements you are using the actin-myosin myofilaments, and the production of force in this case happens in the "same way".
The advantage of the eccentric movement compared to the concentric in relation to your question is that the force in the concentric part is predominantly a result of the actin-myosin cross-bridges, whereas in the eccentric part you have the action of the "active" actin-myosin cross-bridges AND the "passive part" titin.

@araclavie eccentric exercise is needed for hypertrophy (damages muscle through micro tears for it to grow) and can help with lengthening the muscle tissue.
From peaty point of view, one would want to avoid this stress and therefore use Concentric for more strength gain relative to muscle growth.

Is intercourse concentric only?
Put yourself on fire for peak energy metabolism.
Ignore, judge, overcommit.

Benefits of avoiding eccentric / concentric only:
-(?) younger mitochondriaNegatives of avoiding eccentric:
-have to vastly reduce your exercise selection
-less gainz
-DYEL?regular concentric/eccentric bodybuilding training contains best of both worlds, youre getting hypertrophy and also all the benefits of concentric. Lets see you grow big biceps while avoiding eccentric training, its practically impossible unless you want to drop your barbells or dumbells after every rep. in fact if you look at what all the top oldschool bodybuilders say is to "control the eccentric"
watch this video of arnold doing biceps curls,
https://www.instagram.com/p/C3f4hRGsQIO/hes putting way more effort into the concentric and hes merely controlling the eccentric, he's not really fighting against it, hes not trying to slow the negative portion. this is how all the oldschool legends trained. All the internet fitness gurus who tell you to "fight the eccentric" and to "spend more time in the eccentric" actually have no idea how the golden era and best looking bodybuilders trained, all the emphasis was put on the concentric.
breakfast for dinner enjoyer

Yes, barring specific positions.

Hypertrophy between concentric and eccentric seems to be basically the same when you match the mechanical tension. What's different is the type of hypertrophy (diameter vs. fiber length). So I would add:
Benefits of avoiding eccentric / concentric only
-Less muscle damage, so you can exercise more days, recovery is very fast and you don't have to divide muscle protein synthesis too much between hypertrophy and muscle repair(not the same thing).
-Same hypertrophy potential(but in a different way)
-Apparently reset of repeated bout effectBut I agree if you approach it in the standard mindset of 6-8 reps or more per set you'll look weird and it's quite difficult.
As my background is in Olympic lifting and I always liked working with singles/doubles, it was quite easy to apply. The same results or better compared to my colleagues at the time without getting too debilitated

If she loves you, then she'll understand.

I don’t agree with Dr. Peat on this. Eccentric exercise helps build protective strength in muscles and connective tissue that can prevent injury.
