The effects of testosterone on exercise & muscle

Testosterone is a male hormone that is essential for a few of the body’s natural functions and systems. We also know that it plays a key role in masculinity and muscularity. Testosterone boosting has long been associated with building leaner and bigger muscles and also in improving performance of muscles during training. Let’s have a deeper look at what exactly are the effects of testosterone on muscle and training.

What is testosterone?

Testosterone is the primary male sex hormone and plays a key role in the development of male reproductive tissues, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. Female ovaries also create testosterone, although in much smaller amounts than in males.

What is the effect of testosterone on muscle mass?

Increased levels of testosterone are what enables males to have naturally higher muscle mass than females. Testosterone also increases neurotransmitters, which encourage tissue growth. It interacts with nuclear receptors in DNA, which causes protein synthesis. Testosterone increases levels of growth hormone that makes exercise more likely to build muscle.[1]

What is the effect of testosterone on exercise?

We already understand that testosterone increases levels of growth hormone that makes exercise more likely to build muscle. Growth hormone also plays a part in protein synthesis. It provides an anabolic effect to muscle growth and strength. It binds to receptors on the surface of muscle cells and stimulates protein synthesis to build the muscle after “trauma” during resistance training. Testosterone can also help men to control and lower their body fat percentage.[2]


What are the negative effects of low testosterone levels?

  • Fatigue
  • Decreased muscle mass
  • Increased body fat
  • Decreased bone mass
  • Mood changes
  • Impaired memory
  • Decreased libido

Despite all the negative press that testosterone boosters have received, there are healthy ways to increase your testosterone to levels that benefit your training goals. The most important thing is that you aim for products that naturally boost your testo production and not artificially supplement it. It is always imperative to talk to your doctor or healthcare specialist before using any hormone boosting products, especially if you have underlying health conditions.
