Overweight and obese men who partook in 12 weeks of aerobic exercise saw significantly boosted testosterone levels, according to new research from Tsukuba University, Tsukuba, Japan, and Ryutsu Keizai University, Ryugasaki, Japan.
A men’s health expert says the paper “lays the foundation for giving patients really accurate data on what could be potentially a more holistic approach for treating low testosterone.”
In a previous study, a collaboration between the two universities had discovered that a combination of diet and exercise was effective in increasing the testosterone in this population. However, for this new study, the researchers wanted to examine specifically the effect of regular aerobic exercise on testosterone levels.
For the study, which was presented at the American Physiological Society’s Integrative Biology of Exercise VII meeting in Phoenix, the authors compared 16 normal-weight men to 28 overweight/obese men, and none of the participants exercised regularly. Each volunteer finished a 12-week aerobic exercise plan that consisted of 40–60 minutes of walking or jogging on 1 to 3 days per week. Testosterone levels were recorded at the conclusion of the study.
The findings showed that while testosterone levels were still at lower levels than the normal-weight men at baseline, overweight ...
