Bodybuilding – source of youth

Friday, August 26th, 2011

Most gerontologists (scientists involved in the aging method) readily agree with the statement that close to the true fountain of youth are regular, sensible exercise performed including bodybuilding. Aging processes are characterized by the fact that a gradual decrease in the secretion of various hormones essential for the organism, which causes overlapping of numerous degenerative processes. Research indicates, however, that the appropriate exercises maintain peak levels of hormones & move away in the coursework of the lots of physical signs associated with aging.

New research published in the journal “Metabolism” shows that exercise may even restore testosterone levels in men who had not practiced. After a workout on a stationary bicycle testosterone levels in men aged 66-76 years increased by an average of 39%. The amount of hormone transport globulin (SHBG), which over 50% of the testosterone circulating in the blood, also rose by 19%. It is important as breaking down the testosterone SHBG in the liver.

Because testosterone is an important muscle anabolic hormone , this study shows that progress in the development of muscle can be maintained in spite of his advanced age. Maintaining the level of testosterone also has beneficial effects on bones & increases libido.

D-aspartic acid (DAA) – raises level of testosterone

Friday, August 19th, 2011

Aspartic acid, D– is a physiological amino acid which is formed in the body because of the conversion of L-aspartic acid to D-aspartate. It plays an important role in the production of sperm & sex hormones. It is a strong sexual stimulant, increases libido, improves erectile function, ejaculation, & prolongs the period of relationship & the same feeling of orgasm. Studies in humans have shown a significant increase in levels of luteinizing hormone (lutropin, LH). LH binding to receptors located on the surface of Leydig cells increases the synthesis of cyclic AMP (cAMP) & detachment from the side chain of cholesterol molecules. This is a key decisive reaction of increased steroidogenesis & thus the formation of testosterone . In addition, D-aspartic acid in your body increases dopamine & GABA levels & also increases production of nitric oxide (NO2, NO3).

USE OF ANABOLIC STEROIDS IN SPORTS PRACTICE
THERE IS NO ACTIVITY Anabolic Steroids’ androgens – the positive effect on growth MUSCLE IS PARTICULARLY PSYCHOLOGICAL – SERIOUS SIDE EFFECTS AND TOXIC.

The use of pharmacological agents in order to increase strength & muscle tropism, has been gradually increasing in the practice of various sporting disciplines, in order to represent, in recent years, an issue of ethical health of non-minor. Among these substances, the most useful ones are the so-called anabolic steroids, which have features similar to male sex hormones produced by the interstitial cells of the testis, of which testosterone is the mixture simpler product. (IN THE PHOTO: liver cancer caused by the use of anabolic steroids. The liver adenoma was surgically removed).
‘S observation that these hormones, administered in hypogonadal males (ie, suffering from lack of testosterone production), had a significant effect on the development of muscle mass, has led to the idea that pharmacological doses (ie higher than those produced by the body ) of these compounds, could promote an increase in “lean mass” of the normal subject.
Physiologically, the male testosterone increases dramatically at puberty & is member of the hormone to the following functions:

Development of primary & secondary sexual characteristics (development of the genitals, tone of voice, facial hair, overweight distribution & muscle, prostate & accessory sex organs);
Desire & sexual potency;
Regulate the production of sperm;
Effects on various organs & tissues (red blood cell production, nitrogen balance, etc..)

The production of testosterone occurs in the testis, under the stimulus of hormones produced by the pituitary, the FSH & LH gonadropine (also appointed to the stimulation of production of germ cells), & these, in turn, are regulated by testosterone plasma concentrations dl An increase of this hormone leads to an inhibition of gonadotrophin; its reduction stimulates the secretion. Thus, plasma levels of testosterone are maintained constant from precursors of sperm & the ensured continuous production of germ cells, precursors of sperm.
It is therefore clear that the exogenous administration of androgens interfere with this regulation system, inhibiting the activity is hormone-producing gonadal germinative that, clinically obvious fact with the reduction of testicular volume (Marco Cappa et al.). It ‘was, in fact, shown that, in the coursework of anabolic steroids, the longitudinal diameter decreased an average of one cm.
For this reason, pharmacological research has focused in an try to fine-tune the testosterone molecule in order to get substances with the metabolic action alone. However, it’s not yet been synthesized anabolic steroid devoid of any androgenic activity.
