One gram bromelain daily maintains testosterone levels after heavy exertion
Extreme exertion, such as running a marathon, lowers testosterone levels. Researchers at the University of Tasmania may have discovered a way to prevent this from happening. Supplementation with one gram of bromelain daily maintains the concentration of testosterone in the blood during periods of intense physical activity, they reported in the European Journal of Sport Sciences.
Bromelain
Study
The researchers used a product manufactured by the Australian Bio Concepts. However, the company did not finance the study. So this was not a sponsored study.
The experiment lasted for 6 days. During this period the cyclists participated in a six-day competition, in which they cycled about one hundred kilometres a day. During the event the researchers monitored the subjects' blood.
Results
How exactly bromelain supplementation maintains testosterone levels the researchers don't know. Anti-catabolism at least does not play a significant role. The researchers found no noticeable effects of bromelain on the concentration of the enzymes LDH and CK in the blood. LDH and CK are indicators of muscle breakdown.
