Testosterone Release, Resistance Training and The Number of Sets

Posted on October 31, 2024 by Robert Barrington

Testosterone is released following exercise, but the amount released depends largely on the type of exercise employed. Generally resistance training results in higher amounts of testosterone produced compared to other forms of exercise. The number of sets undertaken within that … Continue reading →

Testosterone Release and Exercise Intensity

Posted on October 30, 2024 by Robert Barrington

Testosterone can be increased through resistance training as well as other exercise. However, the exact reaction of the metabolism of the individual depends on the type of exercise performed. Exercise intensity is defined as the amount of force exerted by … Continue reading →

Vitamin E and Exercise

Posted on October 29, 2024 by Robert Barrington

Exercise is associated with significant metabolic stress and the degree of this stress is related to the relative intensity of the exercise and the fitness of the individual. Eccentric skeletal muscle movements, those that require contraction under conditions of elongation, … Continue reading →

D-Aspartic Acid: Dosage Considerations

Posted on October 28, 2024 by Robert Barrington

Studies consistently show that male animals respond to D-aspartic acid supplementation with increased synthesis of testosterone. However, the human results from studies have been more inconsistent, and this likely relates to either methodological problems with controlling human diets and lifestyles, … Continue reading →

Beta Adrenergic Receptors: Skeletal Muscle

Posted on October 25, 2024 by Robert Barrington

One of the effects of administering β-adrenergic agonists to sheep, cattle and pigs is the increase in lean mass that they experience. Therefore β-adrenergic agonists are thought to stimulate hypertrophy, reduce protein degradation, or a combination of both. The mechanisms … Continue reading →

Taurine: Antioxidant?

Posted on October 24, 2024 by Robert Barrington

The role of taurine as an antioxidant may be of primary importance in the male reproductive tract. Here the taurine may participate in fractions that protect the polyunsaturated membranes of spermatozoa and this may explain the reproductive benefits of taurine. … Continue reading →

Cyclic AMP and Growth

Posted on October 23, 2024 by Robert Barrington

Evidence suggests that compounds such as caffeine, ephedrine and clenbuterol may be able to alter mammalian growth rates because they can alter intracellular levels of cyclic AMP (cAMP). This research has perhaps been exemplified by studies on cattle fed high … Continue reading →

Beta Adrenergic Receptors and Growth

Posted on October 22, 2024 by Robert Barrington

β-adrenergic receptors are those that bind adrenaline or noradrenaline, and which from this binding elicit a cellular response using the G-protein coupled cyclic AMP and protein kinase A system. This system forms the CREB (cAMP response element binding protein) system. … Continue reading →

Taurine: Does it Interact with Proteins?

Posted on October 21, 2024 by Robert Barrington

Taurine may exert some of its beneficial physiological effects by binding to proteins. For example, it is known that taurine can bind to transport proteins and in this way affects the flux of ions such as calcium. However, it is … Continue reading →

Taurine: Phospholipids

Posted on October 18, 2024 by Robert Barrington

Taurine may have the ability to interact with phospholipids and this may affect cell membranes. Taurine binds to phospholipids with low affinity to a specific binding site in the membrane. This affinity is within physiological concentrations for taurine, and this … Continue reading →
