What Male Athletes Need to Know About Testosterone

Posted on Oct 23 2014 - 2:57pm by Simbaa Da Lion

This is a start of a array that will residence a series of issues that group understanding with and a hormones that impact their daily life. Today, we inspect a few studies that competence bother your seductiveness in how certain movements can rise your testosterone some-more than others.


Chemistry and Endocrinology

Before looking into these studies, it is critical to know testosterone and a duty in a physique and brain. Testosterone is an androgen and is a form of lipid, or fat. In a lipid family, it is deliberate a steroid hormone.

Steroid hormones are stoical of CO atoms firm together into 4 ring-like structures. The organic structure of testosterone will not demeanour a same as a other steroid hormone counterparts, like estrogen, yet they do go to a same family.


Testosterone and Body Function

Testosterone has both approach and surreptitious effects on flesh tissue. It can foster expansion hormone responses in a pituitary, that can change protein singularity in muscles. The power communication with other hormones demonstrates a rarely interdependent inlet of a neuroendocrine-immune complement in conversion a strength and distance of a fundamental muscles. The effects of testosterone on a expansion of strength and flesh distance are also associated to a change of testosterone on a shaken system, privately a pineal gland and maiden pituitary gland.


Even yet we are especially articulate about testosterone, it’s critical to speak about a other hormones that assistance in a recover of testosterone from a testes, privately luteinizing hormone (LH). LH is named for a functions in females, yet has an critical purpose in males. LH binds to a interstitial cells in a testes and causes them to hide testosterone.

The Kettlebell Swing and Increased Testosterone  

The Journal of Strength and Conditioning Research investigated strident hormonal responses to a kettlebell pitch transformation regulating 10 recreationally lerned group (24±4 years of age, 175±6 cm, 78.7±9.9 kg). Each male achieved twelve rounds of thirty seconds of 16kg kettlebell swings, swapping with thirty seconds of rest. Blood samples were collected before (PRE), immediately after (IP), fifteen mins after (P15), and thirty mins after (P30). Hormones that were analyzed enclosed testosterone, expansion hormone, cortisol, and lactate concentrations.


Since we are vocalization of testosterone, we will go by those numbers specifically:


  • Testosterone was significantly aloft during IP than during PRE, P15, or P30. The numbers enclosed a following: PRE 28÷3; IP 32±4, P15 29±3; P30 27± 3 nmol.
  • Growth hormone was aloft during IP, P15, and P30 than during PRE
  • Cortisol was aloft during IP and P15 than during PRE or P30
  • Lactate was aloft during IP, P15, and P30 than during PRE


The practice custom constructed an strident boost in hormones concerned in flesh adaptations, so a kettlebell pitch practice competence yield a good addition to insurgency training programs.


Hormonal Response to Free Weights and Machine Exercises

Similar to a investigate above, a Journal of Strength and Conditioning Research conducted a investigate that analyzed strident hormonal response to giveaway weights and certain appurtenance exercises. This was finished with a same conditions as a kettlebell investigate in pleasantness to PRE, IP, P15, P30 and time of blood samples. Ten group (25 ± 3 age, 179 ± 7 cm, 84.2± 10.5 kg) participated in this investigate regulating identical lower-body multi-joint transformation giveaway weight and appurtenance exercises. Each male finished 6 sets of 10 repetitions of hunker or leg press during a same relations power distant by one week.


The formula of a investigate demonstrated:


Testosterone and Growth Hormone: poignant boost during IP, yet a IP concentrations during were larger for a hunker than a leg press.


  • Testosterone Squat Numbers: (31.4 ± 10.3 nmolŸL(-1))
  • Growth Hormone Squat Numbers: (9.5 ± 7.3 μŸL(-1)
  • Testosterone Leg Press Numbers: (26.9 ± 7.8 nmolŸL(-1))
  • Growth Hormone Leg Press Numbers: (2.8 ± 3.2 μŸL(-1))


At P15 and P30 Growth Hormone was Greater during a Squat than a leg press


  • Squat Numbers: (P15: 12.3 ± 8.9μŸL(-1)) (P30: 12 ± 8.9 μŸL(-1))
  • Leg Press Numbers: (P15 4.8 ± 3.4 μŸL(-1)) (P30 5.4 ± 4.1 μŸL(-1))


Cortisol saw identical results, with an boost after exercise, yet hormone levels were larger for a hunker than a leg press.


The sum work (external bucket and physique mass moved) was larger for a hunker than a leg press, yet a rating of viewed effort did not differ between a two. It can be unspoken that giveaway weights seem to satisfy larger hormonal responses to resistant exercises than machines regulating identical lower-body, multi-joint movements and primary movers.

The Growing Problem of Low Testosterone

According to a International Journal of Endocrinology, low testosterone is manifested in many ways including erectile dysfunction, low libido, detriment of morning erections, vexed mood, and nap disturbances. Men with low testosterone also showed reduction diurnal movement (levels of a piece in a 24-hour period) in their testosterone levels compared to younger group with normal levels of testosterone.


Obesity has a vast impact on low testosterone. In portly males, levels of testosterone are reduced in suit to a grade of obesity. To fight this, a initial step in shortening abdominal fat is dietary and lifestyle changes. Men are speedy to mix aerobic practice and strength training. With ongoing strength training, an boost in fast-twitch flesh fibers increases glucose blazing capacity, that decreases insulin levels. Weight detriment will boost levels of testosterone and should enlarge a affects of lifestyle and practice advice.


The upkeep of biologically normal testosterone levels in males is essentially critical to practice adaptations and protected competition participation. One of a best ways to say your levels is by eating rightly and carrying a scold change of strength and aerobic exercise. If we feel we need assistance with diet and exercise, find out a nutritionist or practice physiologist (exercise professional) to get on a right trail to good hormonal health.
