After careful review of the medical data, it has been hypothesized that declining levels rather than high levels of anabolic steroids are major contributors to prostate cancer (Prehn 1999)– a fact borne out in my own research on US prostate cancer epidemiology. In addition, my own work published in JAMA in 1999 found elevated levels of testosterone in U.S. males who had undergone testosterone therapy, suggesting that testosterone itself is a primary risk factor for the development and progression of prostate cancer (Prehn 1999).How Much Exercise Is Recommended?Exercise is widely recommended as a means of increasing muscle mass, maintaining healthy bone, preventing the onset of osteoporosis, preventing the loss of muscle after vigorous muscle-extension exercises as well as increasing bone mineral density, testoprop chang. Exercise can increase bone accretion and is therefore recommended for the prevention of osteoporosis (Dale and Naylor 2005). This seems like a reasonable way of thinking about exercise that allows for healthy health and healthy bones. Unfortunately, some studies suggest that moderate exercise may be harmful to bone and may lead to increased risk of fracture and to fractures with a greater number of fractures, especially in more severe fractures (Hollingshead and Wight 1997), anabolic gainz review.Although I am not convinced that moderate exercise is in fact harmful, there seems to be the impression that high levels of exercise are beneficial for maintaining bone health and bone mineralization; however, research on human health indicates that high exercise levels are generally detrimental to bone health as compared to low levels of vigorous exercise (Lavie et al 2003; Schut et al 1992).What Kind of Exercise and What Kind of Calorie Intake Might Be Appropriate for People to Exercise?The exercise recommendations presented here for moderate resistance training and endurance exercise seem to be the best we have to offer as regards moderate exercise and calorie intake, anabolic gainz review. It should also be noted that moderate resistance training and endurance training can result in muscle hypertrophy that is not only beneficial to bone and muscle, but has been reported to increase lean mass (Frieden et al 1996; Loughran and Saper 1998). Therefore, the recommendation of 1-2 hours per week of moderate resistance training and endurance training at 80 to 75% (or higher) of maximum heart rate/intensity may be appropriate for a person to undertake.I hope this information is useful to those who are thinking about incorporating resistance training and endurance training into their lives. Although it is unlikely that one will find any studies indicating that it does much to prevent prostate cancer, it's also quite possible that moderate exercise does help prevent bone loss, increase lean mass and, in particular, increase skeletal muscle mass, alli diet pills at walgreens.
