Long-term exercise with weight given significant adaptation, the result of which is to increase the size, strength and power, coached musculature. The increase in anabolic hormones caused by weight training can increase hormonal interaction with various cellular mechanisms, and promote the development of muscle protein contractile units. When there is stimulation of the motor neuron to the top of the muscle contraction, various signals are sent from the brain to the muscles and endocrine glands.
Hormones released during and after resistance training because of physiological stress caused by exercise. Secretion of hormones, the body provides information on the amount and type of physiological stress (eg, epinephrine), metabolic demands (eg, insulin), and the need for changes in metabolism during rest. Thus, certain models of neural stimulation with resistance training, lead to certain hormonal changes, which together with the drive the specific mechanisms related to the restoration and adaptation to severe physical stress.
Stress and hormonal response scheme combine to form an adaptive response of tissues to a specific training program (such as weightlifting or TA). So, in order not to knock you even more confused, defined force produced by the muscle fibers, determines the changes in hormone receptor sensitivity to anabolic hormones, as well as changes in the receptor synthesis. Just one or two days of resistance training can increase the number of androgen receptors (receptors for testosterone) in the muscle tissue. Collectively, these changes result in muscle growth and increase muscle strength in intact.

There is an increase in the synthesis of actin and myosin and decrease protein degradation. Now, there is a lack of all these cool things in strength training. If the stress is too large for the athlete, in the catabolic activity may exceed the anabolic muscle, resulting in failure to anabolic hormones bind to receptors or receptors in muscle tissue suppression. Therefore, hormonal activity is important, both during and after training to respond to the demands of physical stress. The amount of hormone response depends on the amount of stimulated tissue, the amount of the reconstructed tissue and the amount of tissue, reduced after weight training.
Only the muscle fibers involved in strength training are able to adapt. That is where genetics and types of muscle fibers play a role (I know that some of you were waiting for it). Some fibers may be closer to the athlete regarding genetic ceiling tile size, whereas others may have greater potential for growth. This is the moment for which the people conclude that Krossfitera use of doping, because many people believe that people have a certain ceiling for cell growth, but in the end, while we can not see your genetic year, no one can know sure what your genetic ceiling for the cells of skeletal muscle size. Just because someone does not look like you, it does not mean it’s impossible.
Now back to the hormones, the degree of hormonal interactions in the growth of muscle fibers is directly related to the size of the adaptation of the fibers. Thus, if the exercise program uses the same exercise again and again, only a subset of muscle fibers associated with this movement will be activated and stimulated to grow. Since this embodiment CrossFit diversity in most cases people work different muscle groups at any point in time, which helps the growth of muscle groups, rather than just a single. Studies have shown that the amount of work, the period of rest between sets and the type of exercises are essential for the adaptation response and the magnitude of hormonal changes in men and women.
