Deadlifts and CNS

Training Powerlifting
21

Its all interrelated. How are all these muscles getting stimulated? Is their a tremendous amount of microtrauma involved in sprinting? I honestly dont know, but I believe that sprinting uses alot of high threshold motor units but I dont think there is much microtrauma. So if the whole body fatigue and microtrauma is your arguement, then try this. 10 sets of 50 meter sprints with a 10 minute rest between each.

Perform 7 days a week and tell me how your body feels at the end. Its not just the microtrauma. Your body cannot exert itself at extremely high levels too often, it just cannot. That is why plyometrics are not performed that often. Partly because your muscles and tendons etc. have to recover, but also because it is dangerous to do plyos with in a fatigued state because you will not respond as quickly as usual when performing them.

What I took away from Chad’s CNS article was the possibility of strengthening muscle cells by getting the CNS to think it was doing a particular movement - the “visualization” approach. I don’t recall discussion of CNS fatigue. It was a great article and I’ve read it twice but will take another look.

My initiation of this thread (although probably not clearly stated) was about trying to understand the difference between muscle fatigue (and recovery time and CNS fatigue (and recovery time). Is there a difference are are they one and the same?

A great question. It is very complicated and I definitely dont completely understand it. This does not go just for the deadlift but any exercise.

Ok if you look up recovery times after you have exercised a muscle for the most part you will see between 24 and 72 hours of recovery time. I think this may mean just the muscle fiber recovery time and im guessing it is based on some type of blood marker indicating muscle trauma or it could just be controlled experiments with people lifting. Now I suppose it is possible for your body to recover from an intense deadlifting workout in 3 days in the muscle regeneration area, but we all know that a 5-9 day rest works best for heavy deadlifting.

I think the difference is the capability of the body to use those motor units that incurred the most damage during the exercise session is delayed and requires an even longer recovery time. I dont know why, but I know the recovery time most books will talk about is not of the neurological nature. Reason being is I bet exercises like leg extensions were used because they are very simple 1 joint you know the muscle that is generating the force it is easy to standardize form and such, now I think you could do leg extensions and rest a day and be fine to perform again at the same level, because what you are dealing with there is more muscular in nature and the nervous system is not acting as powerfully in that exercise.

A good way to start your deads is racked. Thigh high or so on some squat hooks. Allows you to do more weight and take advantage of the reflex going down.

Yhea but then its no longer a DEAD ( as in dead in the floor) lift its a get the weight out ofn the rack bounce it off the ground not having to use strating strength lift.

Just like repping the second one is always easier inless you do a long pause. Does that means it better more stimulus for growth in strength and size NO. The reason the DL is the king is due to the lack of the stretch reflex etc and having to use sheer balls out real strength to move said dead Load off the floor.

Is he competing? Then the increased load will still be just that. He doesn’t need ‘maximal’ pull for anything else.

I never said anything about bouncing.
It’s just a different way to start sometimes to max the load.

Why the anger Phil?

LOL anger Im not sure where you got anger just pointing out a mistake IMO. doing what you say with the DL is juat as bad as say loading extra load on the bar and doing 1/4 squats.

Drop the friggin load and do them right. You will get as much or more stimulaus from having to start from a dead stop.

That and if he cant get the load off the ground well prettu good idea hge’s not ready for that load yet where as going form a racked position he may just over load mucles etc that are not quite ready and Bingo Injury.

I just see no need in cheating the true value of the exercise for an ego stoke that “Allows you to do more weight” but is none the more effective.

Have a Nice Day LOL.

Actually–you’re wrong Phil.

It’s not about ego or making it easier. It’s about a process that allows you to handle more weight.

If you haven’t "cheated’ in your program before, you’ve missed out on a lot of potential gains. Getting yourself accustomed to the load is part of the process. There are times in a routine for 1/4 squats as well.

It allows you to do more weight and is quite effective.

Stay with what you know–like how to eat or something like that. Clearly, advance techniques w/r/t weight training are beyond your scope.

Last week I planned on doing 3x5 with 405. Pulled a hard rep at 405 and decided to bag it. This after 3x8 with 375 a week earlier. Today I did 3x5 with 365. Obviously backing off quite a bit but very little fatigue (muscular and CNS) and not much need for rest between sets. I also was very conscious of lowering each rep slowly and not getting any bounce off the floor - however I did not relax between reps. They have those damn octagonal plates at 24 hour fitness which I’ve always feared might mess up my back if they hit the floor hard so the light touch is probably a good idea for that reason.

Anyway, it will be interesting to see if I experience less CNS fatigue as I increase the weight on this 3x5 cycle.

i have read the posts in this thread. i still don\t understand what a fried cns is and how i recognize it. I have however experienced serious reduction in strength that lasted like a month after testing my DL. maybe i can attribute that to a ‘fried cns’? should i be worried about it? more than hampering the training, is it dangerous to get a fried cns?

oops! i see now this thread is more than 10 year old… well anyway

Came here to say that it was 10 years old.

Basicly you hit a heavy single double triple, something heavy and hard then next time you do the lift before your at hard weight it feels ridiculously heavy. That is my take on it. I pulled 730 on Monday. And went to pull 605 on Saturday and it felt like a max granted I was sick all week.

This is nonsense.
