Serum Selenium, Lipoproteins and Testosterone Responses to a Single Session of Circuit Resistance Exercise in Male College Students

The purpose of this study was to examine serum selenium (se), lipoproteins and testosterone responses to a single session of circuit resistance exercise. fourteen male college students volunteered in the present study. blood samples were taken at 30minutes before, immediately after 25 and 60minutes of single session of circuit resistance exercise (10 exercise, 20s for each exercise, and at 60%lrm). a significant increase in serum selenium and a decrease in testosterone, very low density lipoprotein cholesterol (vldl-c), and low density lipoprotein were found during recovery period. the present data indicate that a single session of circuit resistance exercise was able to change serum se, lipoproteins and testosterone levels. an acute increased se and decreased testosterone might indicate an energy deficiency following a circuit resistance exercise.
