This is another chicken-and-egg scenario. Another common culprit: a tumor in the pituitary gland, a tiny organ near the base of the brain that releases a compound called luteinizing hormone. At rest, testosterone appears to be lower in the endurance-trained male than in the untrained male. However, these studies did not include high mileage runners. Granted, man did have bigger brains and was able to strategize with his fellow hunters.
According to a , male runners who ran more than 40 miles per week had noticeably lower T levels compared to those who train in short-distance running. Increased Fatloss Research also points to increased fat loss compared to steady state training. This bears repeating: The people with higher cortisol levels were the ones more likely to gain more muscle over the course of the study.

This will be a post focused on the effects in men, mostly as the amount of literature on the effects of training on the female reproductive system is very extensive and clearly requires a separate review. Testosterone is produced in the testis and it has been speculated that reduced testicular blood flow or damaging testicular heating might influence the production. There are also indications that low testosterone levels might lead to increased incidence of cardiovascular diseases and even higher mortality, but in the studies conducted so far there are a number of co-founding factors such as presence of type 2 diabetes and it is difficult to say what is the hen and the egg in these studies. Sprint speed comes from 3 things: Steps how many steps you can take per second , Force applied to the ground, and Contact length distance you cover over one contact period.
The men whose starting weight was already at healthy levels did not see a difference. Sprint training gives you another huge benefit in that they are quick to do. In , a group of both overweight and healthy weight men participate in a 12-week exercise program that saw the group do 40-60 minutes of either walking or jogging 1-3 times per week at only mild to moderate intensity.

Weight training stimulates muscle growth by tearing down muscle tissue, requiring your body to repair it. In another done at Universidade Federal de Sao Paulo in Brazil, researchers examined the serum levels of 20 men before and after completing a 26. Testosterone is a grown hormone.
