All of fatigue | Kulturystyka.pl
Physical fatigue is a physiological state that results in the temporary reduction in mobility of the body. Fatigue is a mechanism for protecting the body against 12v electric heater excessive effort and thus to excessive hepatic homeostasis. Physical fatigue caused by intensive muscle work, following which certain biochemical changes occur. Functional changes also apply to the nervous and humoral thus homeostasis is disrupted. 12v electric heater
Fatigue is caused by the following factors: - working tissue hypoxia; - the accumulation of metabolites of anaerobic metabolism; - depletion of muscle glycogen, - dehydration myocytes;
- Changes in the functional status of the CNS (neurons fatigue induction braking impulse). Fatigue is a subjective symptom 12v electric heater of fatigue. The degree of fatigue usually corresponds to that of the actual reduction in the ability to move and work. However, there are situations in which these relationships are disrupted. Fatigue is caused by factors for mental (emotional). Man has the ability to call home state of fatigue 12v electric heater in the absence of fatigue actual (muscle), such as lack of psychological motivation to exercise (lack of interest in mental health movement at a time) while maintaining the project. Fatigue is the reason for low productivity and efficiency of movement (work). Situation is different: there is a real muscle fatigue while maintaining the foundation of mental manifested relevance and willingness to comply with the effective and efficient movement (work). Then traversed (work) do not show lower productivity and efficiency. Performance of work (motion) is accompanied by emotional stress associated with interest the work, knowing the great purpose. These are examples that prove the impact of I and II of the signals and the action on the course 12v electric heater of mental fatigue and exhaustion and indirectly (through the nervous system) in the same work the muscles.
The course of development of fatigue affect trophic influence of the sympathetic 12v electric heater nerve irritation nerwowegoPrzy intensity processes are oxidative ATP synthesis, increasing the reserve base and is electrically conductive. Sympathetic nerve stimulation also stimulates impulse conduction of synaptic connections. 12v electric heater
The tired muscles decreases the amplitude of contractions, increases in diastolic phase, relaxation becomes incomplete contracture develops. Decreases excitability (increased excitability threshold), extends the period of activation of latent (time from the beginning of stimulation to muscle contraction). Fatigue refers to the first phase of plate movement (muscle-nerve synapses).
1 The theory of exhaustion (Verworn `ai Schiff` s) - fatigue is a result of consumption of energy materials in working muscle. Studies have shown that muscle fatigue occurs before the depletion of the substance energiodajnych (glycogen, glucose). 12v electric heater
3 Neurogenic theory of Pavlovian Sjeczenowa, Orbelli `s and Krestownikowa - fatigue is the result of nervous exhaustion and inhibition of neurotransmission and neuromuscular blockade. 12v electric heater Condition of fatigue is caused mainly changes in the nervous system. A large share of the development of the cerebral cortex takes fatigue and the autonomic nervous system.
4 Theory poisoning - is the result of the accumulation of fatigue in the working muscle fatigue specific toxins. Currently, the theory is of historical significance, as addition to the customary and known metabolites were isolated predicted fatigue toxins from the muscles 12v electric heater working hard.
5 The theory of hypoxia - muscle fatigue during operation is due to the increasing lack of oxygen (hypoxia in the muscle) due to the intensive use of intracellular oxygen to breathe.
None of these theories do not fully explain the causes of fatigue. Currently dominated by the concept of synthetic approaches to the process of fatigue, i.e. to explain the reasons for using all theory, except poisoning theory, which has not been proven. With the development of molecular biology, there are theories of fatigue (eg theory of dehydration, electrolyte theory, the theory of mediators, the theory of chain = reciprocal links), examining the process at the molecular level. None, however, can not be accepted uncritically, and indeed it can be pulled back to earlier theories already published (for example, broader theory of neurogenic or exhaustion).
Physical activity of moderate intensity, lasting a long time causes the gradual exhaustion of neurons to regulate and control the functioning of the respiratory and vasomotor. The consequence of this is physiological and biochemical changes, in their systems 12v electric heater (ie, cardiovascular, respiratory). Unnecessary and harmful metabolites are removed on a regular 12v electric heater basis, so you do not accumulate in the working tissues.
