I didn't say all powerlifters should lower their bars slowly because they can. It is easier by far to do than the concentric portion of the rep, you see maybe 70 percent of the neural activity during an eccentric movement compared to a concentric movement at the same force, and eccentric movement is more metabolically efficient. Regardless you're still expending energy on the eccentric portion that could be saved for another (less than full) concentric contraction. Obviously if you're competing strictly for number of repetitions as in crossfit you don't want to worry about the eccentric component when you can let gravity do that work for you but you get the most bang for your buck from eccentric contractions in terms of muscle damage and satellite cell recruitment. They're best for muscle development and generate high levels of tension (much more tension than concentric movement). You should definitely incorporate them into training but depending on your type of performance you can pay variable attention to them

Yes agreed eccentric movements are easier than concentric

Yes a slow eccentric movement will cause more muscle damage


Is it beneficial to slowly lower your deadlifts?

No

1) chance of injury significantly increases
2) high chance that the muscles you are damaging is your lower back, giving you a lower back pump, making further deadlifting in that session uncomfortable. Therefore, you would be better off dropping your deadlifts and getting more deadlift volume in rather than 'more bang for your buck' deadlifts

This is assuming you are not deadlifting to 'workout' your back but to get stronger

Your injury risk should stay the same assuming your technique is good, as I said muscle is stronger eccentrically so unless you're at failure you should have no problem lowering safely. A muscle "pump" has nothing to do with muscle damage, but everything to do with delivery of oxygen and nutrients as well as clearance of co2. Yes an inflammatory response will develop as a result of your workout but that may take an hour or two to establish itself. Extra blood volume should not make your workout uncomfortable, if your back is sore during your workout I would suggest reevaluating your spinal mechanics.

Layne Norton wrote a HUGE article on why you shouldn't lower your deadlifts at over a certain % if training for strength. The risk for the IIRC L5 spine is greatly increased on the eccentric portion of the movement.

Lowering the deadlift slowly - say for a full 3 seconds significantly increases the time under tension which will indeed result in muscle pumps and fatique you significantly faster. Which is another reason it increases the chance of injury

Anyway if you fist a virgins ass are they still a virgin?

Does the pope shit in the woods?

It doesnt matter in the end cos we all die
