Liftin’ Heavy Iron Ups Yo Test & Make You Buff, Right?
Sometimes. It can raise testosterone levels, although only for relatively short periods of time. As far as it causing more of a hypertrophic response than some other approach, well that depends on many things, including your genetics.
There is not a simple association between lifting heavy weights and increased testosterone, no simple corollary exists. Science hasn’t confirmed the hypothesis, as it presently stands. Of course, some studies have shown a transient or temporary response, but even this seems to fit a Bell Curve type of response. Much more likely to increase your Test levels are whether your team won the local football match or that bone-headed turkey on the next bar stool pinches your girlfriend’s behind.
Physiological response to the lifting of heavy weights is complex and multifaceted, dependent on many components: nutritional status, age, training history, injury status, drug use, sex, mindset, session time, rest/sleep condition and genetics to name but a few of these variables.
The ultimate potential to respond via a rise in testosterone to anything, including heavy weights, can pretty confidently be associated with several genes and their combinations existent in your genotype. You are challenging the body’s homeostasis when you start pumping heavy iron. Some will respond to this threat better than others and at least part of this response will certainly have a hormonal component.
During intense training, you will see a testosterone curve initially rise, continue training and you will see it decline and then a cortisol curve will take over. This is just how the body responds and attempts to deal with stressors and perceived threats, a general adaption syndrome (thank you,).
My guess is that, should science ever establish a verifiable long-term relationship, it will have more to do with gene expression and adaptation to factors dependent on an individual’s lifestyle modifications with regard to consistent, heavy resistance training which may be just one, amongst many factors that ultimately influence how buff you get.
