Tall has highlighted that a high number of competitions, monotony of the training ie. 1 rep maximums on DL, high expectations of outcomes, the individual him or herself (wether they have a strong alpha personality or are a shy demure personality),structure of the personality, preexisting
medical conditions such as the flu or a viral infection,, environmental factors (altitude, temperatureand humidity), and even the lack of professional guidance as Nytol shows with the example of him and James taking more time off.

These are all related to the overtraining syndrome, I feel even with so many symptoms a definitive diagnosis and thus criteria for overtraining has yet to be met. I can recover very quickly. Even when my business was not doing well, i split from my gf and ate little i could still lift Personal bests and train intensely, assisted at the time. So the use of AAS's is now thrown in as an added variable to offset the aformentioned symptoms.
The biochemical-metabolic mechanism for the syndrome is yet to be discovered i feel. I have changed my views of last night to a degree.

Im all for a long post but i will summarise the factors i see which govern this syndrome stress.

It can be differentiated in eustress,(negative stress)or positive stress, characterized by the mobilization of every physicaland spiritual strength in a status of excitement causing feelings of joy, satisfaction and happiness.
Jw himself has noted this in many posts.
When we entertain a new stimulus or cycle for instance we temporarily make ourselves in a superman because of the positive stress.The feelin of euphorai many feel on Dianabol. Then as Tall explained there is distress, or negativestress, that represents a damaging situation to the body, whichcan be acute whenever it is intense, and it is installed in a quite
short period of time, or chronic, whenever it is gradually installed
for a longer period. Again easily categorised by the supramaximal training of a powerlifter.

The enalagy that very intense but prolonged maximum training can lead to the athlete feeling almost a sense of fear of increasing lifts day on day,week on week.

The term stress means the status generated by the perception of either the positive or negative stimulus. In my own example,i find the stimulus of a new Personal best or goal very motivating an i feel stress itself is not a symptom for myself in the syndrome. engative or positive feedback form environmental factors only ever makes me push harder.
One that many of us hinted on is the neuroanatomic aspects of the
response to the stress.

This is very well researched inthe animal’s defense reactions that
come to answer to the dangers found in its environment. Different
cerebral structures are involved in different defense strategies,
depending on the level of the threats perceived by the individual.

In a gym environment, this can be seen as a new bar loaded up with a personal best. Then the subject is monitored to see how they psychologicay and neuroanatomically cope with this.

Trials with animal models has evidenced that in potentially dangerous
situations, the structures involved would be the septo-hippocampal
system and the tonsils. These structures receive information
gathered by different sensorial systems, thus creating a
representation of the outside world. This provides us with feedback in the sense of how we as gym trainers view the outside world and inside the gym environment pre training.

The septo-hippocampal system initially performs the conferee
function, comparing the sensorial data synthesis at that moment
with those predictions that take into account the memories stored
in several spots of the Central Nervous System (CNS), as well as
the action plans generated by the prefrontal cortex.

Whenever thereis coherence between both representations, the septo-hippocampalsystem continues to exert its conferee task. However, wheneverit is detected a discrepancy between what is expected and
what happened,(tall hinted at this using me. i expect to sense a positive lift each day i train but this may not be the outcome.) the septo-hippocampal system starts in generatingan inhibition of the behavior, an increasing vigilance level, drivingthe individual’s attention to possible sources of danger.

Whenthe danger signs are clear but still are far away, the tense immobility
reaction is quite common, whose neural substrate is probably
the ventral portion of the periaqueductal gray matter (PGM) of the
mesencephalon

The PGM seems to be the major structure responsible by the
fight and escape schedule that is analogically related to the panic
attacks. Now you all may argue this but from my standpoint i think that overtraining (if i can classify this in a whole account) is a sense of fight or flight especially on the onset of a train cycle. Many tailor a cycle of training stimulus very much along the line of fear factors.

"oh no i cant do max deads a week i'll overtrain. 3 tricep exercises is too much i'll die!" and so forth.

I feel not enough of us try to contradict the PGM enought. Athletes are coached to fight when their instinct is to flight.The PGM, together with the hypothalamus schedulesthe behavior, hormonal and neurovegetative manifestations of thedefense reactions.

It was also verified that the stimulation of theserotonergic way, which is originated in the medial nucleus of the Raphe, and preferably innervates the septo-hippocampus, determinesthe behaviorist inhibition that characterizes the defense.SO we see already that the overtraining stimulus is very much chemically routed, and induced by psychological factors.

The “Central Fatigue Hypothesis” connects
the signs and symptoms of the syndrome to similar symptoms
than those that appear whenever there is an increasing concentration
in the cerebral neurotransmitter serotonin.
serotonin is a monoamine neuro transmitter.

demonstrated that the cerebral serotonin level depends on the free
in the plasma tryptophan that increases whenever the free fatty
acid concentration increases. Due to the increase of the free fatty
acid in the plasma levels during the resistance training, this theory
proposes that the levels of cerebral serotonin increase before the
presence of the overtraining. Unless you have acces to a lab its difficult to keep track of this but i added it because i feel its the major factor in overtraining.

The overtraining syndrome or disorder is defined as a neuroendocrine disorder (hypothalamohypophysial)that results from an imbalance between the demand of the exercise and the functional capability, and it may be aggravated by an inadequate recovery, thus causing a decrease in the sportive and athletic performance, But despite the main reasons i have stated which seems quite an extended list, up to this moment there are not yet quite established criteria.M aybe due to the lack of a culture
implying in a systematic evaluation routine for atheletes and definately bodybuilders..

I have noted the malfunction or imbalance in the autonomous nervous system was presented as the reason for the signs and symptoms of
the syndrome There are several but not well evidenced theories
on the origin and pathophysiological alterations of the overtraining
syndrome. The alterations in the noradrenergic, serotoninergic
and/or dopaminergic activity in the brain (specifically in the
hypothalamic and suprahypothalamic regions) can cause hypothalamic
disorders, but the function of the alterations in the neurotransmitters
during the syndrome is yet unknown.

I think Tall hinted at this and can maybe shed some more light on it..

There is also lackof sufficient evidence for the hypothalamohypophysial-adrenal axle(HPA) alterations, as well as for the alterations in the hypophysial sensitivity.
A quite intensive training period during a training program seems to reduce the adrenocorticotropic (ACTH) and the growth hormone concentrations.

Is this relevent for athletes using 10+ius of synthetic or pharma grade Hgh, or the various peptide use. I argue the overtraining sydrome is greatly reduced if the ACTH and the hgh levels are highly elevated due to supramaximal doseages used by some athletes. (JW i do not mean u one bit )

The overtraining syndrome is defined as a neuroendocrine disorder,
in which the serotonin seems to have an important role in
the physiology, along with other neurotransmitters. But the study
needs to be deepened together with nutritional aspects related to
the tryptophan and the aminoacid levels of the ramified chain that
can be involved in the central fatigue. I said to Nytol i double my nutrition and peptides around very intense lifting cycles. This is touched here due to the aminoacid and tryptophan levels in the body and the nitrogen state . A negative situation coupled with neuro and sero enduced stress and an athlete indeed may experience this syndrome.

My opinion is that overtraining as a syndrome is reletive (in laymens terms) to how you approach your training from a psychological perspective, how well you provide your body with relaxing stimulus, peptide and aas useage and how you cope physically and psychologically after each session.

Aplogies if some bits are worded badly.
I can usually relate most but some conflicted with my own beliefs so i was careful not to load it with my own predetermined views.

Hope this makes for interesting debated.
