Prolonged exercise has been found to decrease plasma testosterone levels in both males and females. One study published in the journal "Medicine & Science in Sports & Exercise" in 1998 examined the effects of marathon running on plasma testosterone levels in men. The researchers found that after a marathon, testosterone levels in the participants were significantly reduced for up to a week following the race. Similar findings have been reported in other studies on endurance exercise and plasma testosterone suppression.
The mechanism behind this decrease in testosterone levels during prolonged exercise is not yet fully understood. It is believed to be influenced by various factors such as increased cortisol levels, a decrease in luteinizing hormone (LH) secretion, and alterations in the testosterone-binding proteins. However, more research is needed to fully understand the exact mechanisms involved.
On the other hand, the statement "people in prison have high plasma testosterone" is a generalization that does not hold true for every individual in prison. Testosterone levels can vary greatly among individuals regardless of their incarceration status. While it is true that some studies have found higher testosterone levels in certain populations, such as male prisoners, it is not a universal characteristic for all individuals in prison.
There are multiple factors that contribute to testosterone levels, including genetics, lifestyle, and overall health. Social factors and the prison environment, such as increased stress levels or potential aggression, may play a role in the higher testosterone levels observed in some incarcerated individuals. However, it is important to note that individual differences exist and there is no universal rule regarding testosterone levels in people who are incarcerated.
