Studies have shown that endurance-trained men tend to have lower levels of testosterone compared to their sedentary counterparts and that resistance-trained men have higher basal testosterone levels. Studies have also found that both endurance- and resistance-trained males had lower testosterone levels than sedentary control subjects. Thus, while it is known that training status can influence the hormone response to exercise, it is not clear whether the mode of training can affect the hormone response to different modes of exercise. Such information could be useful in designing training regimes that will result in the most favorable ratio of anabolic and catabolic hormones.
A first-of-its-kind study attempts to determine the acute steroid hormone response to endurance and resistance exercise bouts of equitable volume in subjects with differing training status. The newly released findings conclude that the circulating endogenous hormone profile is more dependent on exercise mode or intensity than on exercise volume as measured by caloric expenditure. The study also provides evidence that hormone levels and exercise-induced hormone changes are different in subjects of different training status.
