The most recent issue of Idea Fitness Journal presented a summary of recent research results regarding the efficacy of testosterone therapy in promoting health benefits–especially cardiovascular–in older men. The article reports on studies from the University of Western Australia in Perth.
Many of us know that there has been a boom in sales of testosterone products for older men; they make all kinds of promises. Some are over-the-counter creams, while others are prescriptions available only through a physician.
The study at UWA looked at whether circuit training (a workout technique using different exercises in rotation with minimal rest, often with different pieces of equipment) had the same, less, or greater effect on men’s health than these products. The test followed 78 men aged 50-70 who had no history of CV disease, larger-than-normal waist circumference, and low-to-normal T-levels. Four groups were compared: T-therapy with exercise and without; placebo with exercise and without. Results showed that exercise increased testosterone levels, and that creams added even more. Most importantly, cardiovascular health improved more in those who exercised regardless of whether they had T-therapy. One of the investigators, Daniel J. Green, PhD., noted that while T-therapy seemed to increase muscle mass in legs, there seemed to be no benefit in arterial health and function.
A couple of take-aways for older men: 1. There is not magic pill (or cream) for better health; exercise, proper diet, and rest are still key. 2. The focus in older adults should be less on building muscle mass (although it is certainly desirable to maintain what is there), and more on maintaining and improving CV health if one wishes to avoid the maladies such as heart attacks and stroke.
