Testosterone promotes muscle growth.
Scientific studies have shown that two exercises, the squat and the powerlifting-style deadlift, produce a significantly greater release of testosterone than most other exercises.
Always include these two exercises in your natural bodybuilding routines.
Testosterone plays a major role when you want to gain muscle.
This hormone stimulates increased muscle mass by helping to promote the buildup of muscle tissue (anabolic conditions).
This is because the filaments within the muscle fiber that do the work of contraction are proteins (actin and myosin).
Like all proteins, they contain nitrogen, which is derived from the protein foods we eat.
Nitrogen can also be excreted from the body when tissue is broken down (catabolic conditions).
By increasing the retention of nitrogen in the body, testosterone enhances protein synthesis and helps to ensure a positive nitrogen balance, which is when there is more nitrogen retention than excretion.
It also decreases bodyfat levels and promotes the release of growth hormone.
Testosterone acts on the receptors on nerve cells as well, leading to changes in their structural protein content.
This increases the ability of the muscle connected to these nerves to generate the forces required for muscle contraction.
Most testosterone production in men occurs in the testes, although some takes place in the adrenal gland.
Women also have testosterone, although usually only about 10 percent as much as men.
It is produced in the adrenal gland.
The pituitary gland secretes two hormones that control natural testosterone levels.
If you want to build muscle, it's good to know that scientists have known for many years that exercise stimulates the release of testosterone into the bloodstream.
Recently, however, research has been done on individual exercises to determine whether they all produce the same hormone response.
These studies by Kraemer, Fahey, Hakkinen, and others reveal that a significant release of testosterone is achieved during exercises that use large muscle groups, such as the powerlifting-style deadlift, power clean, and squat.
These exercises stimulate testosterone production because a critical mass of the body's muscles is forced to contribute to the completion of the effort.
This may not seem too surprising, as these exercises have long been considered mass-building power movements.
However, studies by Guezennec and others show that the bench press does not produce a similar hormone release.
This is because the body is stationary on a bench during that exercise, so the critical mass of body movement is not achieved.
"The larger muscle mass involved in the squat and deadlift increases the metabolic demands on the body to a critical level, which stimulates an endocrine response," says Dr.
William Kraemer, Director of the Human Performance Laboratory at Ball State University.
"The body recognizes that there is a need to repair itself after the exercise stress, so it produces testosterone and other hormones to carry out the task.
Additional training adaptations are triggered as well, including up-regulation of various receptors and enhanced protein synthesis.
Exercises that do not place such a metabolic demand on the body do not produce the same series of events.
" The inevitable conclusion: you should incorporate these testosterone-releasing exercises into your workout program for muscle of legs and back.
