Can someone please explain to me how resistance training affects hormones? And what effects insulin has on the body post-exercise? Thanks!

darknight08 said:I've already read the article- it mainly relays the releases of hormones in exercising women. I was thinking more along the lines of this:
After a workout, your body levels of GH, testosterone, and cortisol increase. This puts the body in a more catabolic state. The body needs energy so its using glucose by breaking down glycogen and fatty acids for energy. Now if you take in carbohydrate, your insulin level will increase. Does this increase of insulin inhibit any of the above hormones. I know increased levels of insulin will inhibit glucagon. What does it do to GH? Testosterone?

darknight08 said:Can anyone explain why testosterone is inhibited? Is it beneficial to have testosterone levels stay elevated (because it increases muscle growth) or is it better to take in the carb-protein supplement, have testosterone level decrease, and have the IGF1 levels increase for overall muscle hypertrophy? Thanks!
Sorry, what peer reviewed journal was that in? It appears not to be a valid reference.SW VandeCarr said:According to the review article in my previous post (Dudley),

SW VandeCarr said:It cited published articles. I'm not aware of any significant errors but I don't advocate "body building" medicine. I couldn't find any published articles that directly addressed all the questions raised by the OP. I'll find an appropriate article that addresses that specific question and post it.
Don't worry about going that far, I just wanted to be sure the information was correct.SW VandeCarr said:http://jcem.endojournals.org/content/80/2/654.abstract
This trial supports the hypothesis that insulin levels have a positive correlation with testosterone production, although sex hormone binding globulin (SHBG) appears to be inhibited. To the extent that insulin actually is associated with reduced plasma levels of testosterone, this remains unexplained. Since it is known that testosterone has a positive anabolic effect, particularly on skeletal muscle, uptake by skeletal remains a reasonable hypothesis, but I can't point to evidence for this at this time.
SW VandeCarr said:According to the review article in my previous post (Dudley), blood levels of testosterone are decreased with insulin spikes. This is not the same as inhibition. The reason is apparently unknown, but it's thought the reason is that testosterone is taken up by striated (skeletal) muscle. Insulin also increases the stores of muscle glycogen.
Cortisol is released during the stress of heavy exercise and inhibits the effect of insulin on the cell membrane re glucose transport into the cells. This raises blood glucose levels and promotes gluconeogenesis. I'm not aware that insulin directly counteracts the effect of cortisol, but insulin spikes would tend to overcome the effect of cortisol on cell membranes re glucose uptake by cells. During rest after exercise, I would expect cortisol levels to drop, but I'm not sure how fast.
Note that persistently high insulin levels can have negative effects on the kidneys, nervous system and other tissues.

"Furthermore, data from our training study demonstrate that exercise-induced increases in GH and testosterone availability are not necessary for and do not enhance strength and hypertrophy adaptations. Instead, our data lead us to conclude that local mechanisms that are intrinsic to the skeletal muscle tissue performing the resistive contractions (ie, weightlifting) are predominant in stimulating anabolism."
I'm getting contradictory bits of information about testosterone from different studies? WTF?
Resistance training is a form of physical activity that involves using weights or other forms of resistance to build strength, endurance, and muscle mass.
Resistance training can have a significant impact on hormone levels in the body. It can increase the production of anabolic hormones such as testosterone and growth hormone, which are essential for building muscle and improving physical performance.
Yes, resistance training has been shown to help balance hormones in both men and women. It can regulate hormones such as estrogen and cortisol, which can have a positive impact on overall health and well-being.
While any form of resistance training can have a positive effect on hormone balance, some exercises may be more effective than others. Compound exercises that target multiple muscle groups, such as squats, deadlifts, and bench presses, are known to have a greater impact on hormone production and balance.
The frequency of resistance training for optimal hormone balance may vary depending on individual factors. Generally, it is recommended to do resistance training at least 2-3 times per week, with a focus on gradually increasing weight and intensity over time.
