Fadi on muscle fibres & more...

[RyanF]

Thanks for the feedback, Fadi.

^ This is somehting that should be common practise in bodybuilding, mind/muscle connection etc.

I've always assumed it is common practice in bb'ing, just wanted to know Fadi's take on it, since I know that squeezing and other MMC techniques affect the amount of effort that goes into the movement. On that note, mind-muscle connection =/= squeeze. Focusing on squeezing target muscles is one form of mind-muscle connection, but one can definitely achieve mind-muscle connection without focusing on squeezing.

Try it next time on Oly lifts... won't work too well.

What about Force= mass x acceleration?

Let's say your 5 RM is 50 kg. So in scenario 1 you lift this load slowly ( slow concentric ) and (slow eccentric ) or scenario 2 where you lift the load quickly with fast con and controlled eccentric. What is the difference between those two scenarios in terms of stimulating hypertrophy?

Using a bicep curl as an example.

If you can do five reps with 50 kg's you could move the bar quite fast as your biceps strength is fresh, as you progress through the reps your rep speed will slow as the muscle is is losing strength, keep going and your muscle fatigues to the point where you are unable to move the bar.

The idea behind the practice of a slower negative is to fatigue the muscle quickly, more time efficiant.

The positive portion of the moment is pushing against gravity, the muscle is also exposed to friction within the muscle.

The negative portion of the exercise is where everything is happening so you purposely control it, so it it takes 2 seconds to lift it, you should theoretically lower it in 4 seconds to maximize the opportunity for stimulating growth.

Slowing down the rep also guarantees you use no momentum.

The positive portion, you just lift as fast and as hard as you can, but the first two rep you need to purposely slow it down enough to control it, as you fatigue you then start to move as fast as you can.

That's the best way I can it explain it.

But how does it compare in terms of muscle fibre recruitment in terms of lifting normally with moderate/fast speed vs planned artificially slowed down speed?

Time spent doing the exercise.

Try it, one week using one method, the next week doing it the other way, don't do it in the same workout.

Do a barbell curl using the same weight, same rep count.

Not using a controlled cadence you'd need more sets to achieve the same result as one set using a slower negative.

 

[Goosey]

The negative portion of the exercise is where you get most bang for bucks.

You'll often see someone who are unable to positive portion of a chinup, but do the negative quite more easily.

Some have been able to do chinups, after being able to complete a number of negatives after a protracted time.

Is being able to do more weight on a negative a surprise at all. Of course you should be able to do more on the negative because you are just lowing it. Your not actually lifting the weight.

Bleeding obvious in it.

I think everyone understands that concept.

You were the one that said people can often do the negative of a chin when they can't pull themselves up. I would have thought that was obvious. It sounded like you were stating it like it was some strange phenomenon

 

[arthuroarti]

But what about fast concentric? Is it not true that it recruits more muscle fibres?

Ill make it a bit clearer for you, is me or you ffs.

People that are unable to do one full chin up and down have built strength doing just negatives, the down part only, standing on a box and slowly lowering.

 

[Goosey]

No

 

[arthuroarti]

No

please forgive me for stupidity, but then it does not really matter what rep speed you use, correct?

Lifting very slowly on purpose will recruit as many fibres as lifting it fast? But why when lifting slowly it feels harder?

Use any rep speed you want, it's all the same.

It's not about which one is best or which way should you do it, it's simply another way to work the muscle, so sometimes do faster reps and then other times do slower reps.
Use both.

 

[Bazza20]

Lifting slower feels harder because it takes longer. Longer time under tension tires you out.

Lifting faster has to recruit more high threshold motor units because you have to apply more force to the bar to move it fast.

But don't over think it just lift the weight. If you are lifting heavy you can't lift fast anyway.

Exactly Bazza

But did Fadi not say otherwise? As I recall he said that no matter what the lifting speed, muscle fibers will still be recruited due to Size Principle?

If your 10 rm is 25 kg on db curl, how does lifting it faster change the recruitment of motor units?
