Muscle mass increases in direct proportion to blood levels (levels in the bloodstream) of testosterone.
Many athletes increase their circulating levels of testosterone by using anabolic steroids or by exercising the whole body with the appropriate exercises and at a high intensity.
The steroid-receptor complex (which is then formed) influences the cell nucleus (the genetic center of the cell) increase protein synthesis.
Researchers at the University of Connecticut found that full-body exercise increased testosterone levels significantly more than isolated lower-body exercises (such as leg-extension).
The high levels of testosterone induced by the training of the whole body would increase the activity of androgen receptors during the recovery period, a factor that would determine an increase in the rate of protein synthesis, therefore also in muscle mass.
This study showed that intense whole-body training triggers 3 processes that are key to boosting protein synthesis:
- Increased muscle tension
- Increased testosterone level
- Increased activity of androgen receptors
This study proves to be of great scientific-informative value for all natural bodybuilders who want to get the most out of their workouts to increase their muscle mass as much as possible.
