Aerobic Exercise
Scientists followed more than 28,000 male long-distance runners from 1992 to 2002 to determine the effects of running on prostate health. The results, published in October 2008 in "Medicine and Science in Sports and Exercise," found that men who ran a faster pace than 4.5 meters per second had a 32 percent decreased risk of an enlarged prostate than men who ran less than 3 meters per second. Another study published in 2007 in "The Journal of Urology" found that three to five hours of vigorous aerobic exercise weekly helps keep prostate enlargement in check, reduces pain and improves the overall quality of life in patients with prostate disease.
