It is common to talk about CNS fatigue, especially in heavy deadlift! But, it seems to be a myth!
I would like to share the studies and know the opinions of the users.
My topic on this was deleted 4x, I do not know the reason. I have just posted SCIENTIFIC STUDIES. It seems they do not want people to know about their studies.
Has anyone seen anything related? Is it real ?!
see the studies:
*The higher the intensity of exercise, the more CNS fatigue you induce!
NOT! It is quite the opposite:
*A study compared 3 sets of 12 with 1 minute rest between sets vs. 5 sets of 3 with 3 minutes rest between sets. What caused the most fatigue in the central nervous system? NONE!!
No training has caused any CNS fatigue!
- A study of the neuromuscular recovery of elite athletes. They were crouching over 190 kg and running 100 m in 10.44 seconds.
Even in this case, there was no central fatigue!
*Then how would CNS fatigue be?" researchers questioned whether CNS fatigue exists. The vast majority of what was previously thought to be central fatigue can actually be explained by local fatigue. But CNS fatigue probably occurs by other mechanisms. May be neurochemical or metabolic:
*Barnes et al. (2017) have directly studied the claim that deadlifts cause more CNS fatigue than squats. They trained men to perform 8 sets of 2 repetitions at 95% of 1RM with 5 minutes of rest between sets in squatting and ground lifting
*Does CNS fatigue take longer to recover than muscle fatigue?
Latella et al. (2016) studied the recovery time of the CNS after the strength training.
It took 20 minutes for the CNS to recover !!
- Research confirms that CNS fatigue is evident only in the post-workout, even though muscle pain and peripheral neuromuscular fatigue lasted 3 days to recover.
*A study found central fatigue, studied a contraction of 70 minutes in the biceps !!!
I do not think anybody should do a workout like that! Who here does 70min of contraction in biceps?
It is concluded that the fatigue of the CNS recovers in a few minutes (when it happens) and not in a few days as it is customary to report.
