Link beetween CNS overtraining, testosterone level and rep scheme...

[maelpj]

2 question I have been asking myself lately. Im looking for serious answer and not a "just eat a lot and lift heavy" type of answer that everybody would know after lifting weight for 6 month.

1. Does higher rep with lighter weight(less say 8-15 rep with around 90 sec rest) is less stressful on the CNS than lowest rep heavier weight(4-7 rep with longer rest) ?

2. Does your level of natural testosterone impact your cns recovery? We all know testo help your muscle recover faster, but does it help your CNS recover faster? If not, would somebody with high level of testosterone would less suffer from a overtrained cns?

Here a study that don't really answer that but say that testosterone could have the ability to protect the system of neurodegeneration?

Testosterone -- the gonadal sex steroid hormone plays an important role in the central nervous system (CNS) development. One of the less known testosterone actions is neuroprotection. There are some evidences supporting the hypothesis that testosterone may act protectively in neurodegenerative disorders, e.g. Alzheimer's disease (AD), mild cognitive impairment (MCI) or depression. Androgens alter also the morphology, survival and axonal regeneration of motor neurons. These hormones accelerate the regeneration of hamster facial nerve and anterior tibialis sciatic nerve in rabbits following crush axotomy. Androgens exert trophic action in laryngeal motor nucleus of Xenopus laevis. Testosterone is linked to an increase in neuron ****l size, neuritic growth, plasticity and synaptogenesis in both motoneurons of the spinal nucleus of the bulbocavernosus and several populations of pelvic autonomic neurons. The hormone reduced the extent of spinal cord damage in vitro. There are also evidences against the neuroprotective action of testosterone. Testosterone does not protect against methamphetamine-induced neurotoxicity of the dopaminergic system in mice and does not provide significant neuroprotection against glutamate-induced neurotoxicity. Androgens do not prevent striatal dopamine depletion induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in mice. Although the role of testosterone in the CNS is still poorly understood, accumulating evidence suggests that testosterone may create a future treatment for MCI and related cognitive diseases, including dementia and may influence motor neuron regeneration in adulthood. Androgen replacement therapy in selected male populations may hold therapeutic promise for the prevention and/or treatment of age-related disorders associated with neuronal injury.

Discuss.

thanks for all your opinion guys.

1. Yes. Not sure if rest period has much to do with it. CNS overtraining is more likely to occur as a result of heavier (% of 1rm) lifting.

2. Heavier weights create a more significant testosterone response, but ALSO a more significant cortisol response. Heavier weights have a more negligible (smaller increase) impact on insulin sensitivity, HGH, and igf-1.

To create some meaning out of this: If you feel you are close to overtraining (feeling symptoms of excess cortisol production: (elevated resting heartrate, lowered drive during exercise, decreased ability to acheive a pump in the gym, depression, irritability, insomnia, waking up throughout the night)... First try to decrease weights and do higher reps before you fully deload. A full deload is not always necessary if you catch "overtraining" early enough..

As far as what I said about hgh, insulin sensitivity, and igf-1... Going for higher reps allows you to eat higher glycemic meals (more sugar and starch) without it negatively impacting your body composition. Going for higher reps also gives your CNS a little bit of a break.

( as far as the CHO I am talking mainly in the period post lifting, for 5 or 6 hours)

what I toughté. Do you think somebody with higher testosterone level naturally is less subject to CNS overtraining?

Does it matter specifically whether and how T levels affect CNS resilience and recovery, or are you basically just wondering whether there is individual variation in it, regardless of whether it's because of T or 100s of other things?

As far as calories. Increasing test and cortisol will increase the total calories you can ingest and speed up the matabolism for a longer time post training, but there will be less glycogen supercompensation with low reps, and higher risk of overtraining.

Higher rep schemes is a more boosted metabolism post workout but the effect wains at a faster rate... This is good for a partial deload when you think you are close to overtraining. I prefer to reduce heavy (as % 1rm) lifting when I'm cutting, but not entirely eliminate it, because if you entirely eliminate it you may lost the min-muscle connection for that maximal power/strength.
