Serum testosterone and heart rate response to short-term intense exercise in young-athletic subjects

Abstract

The serum testosterone and heart rate responses to short strenuous physical exercise were studied in twenty-one non-athletic male students. The body mass index was also determined. Serum testosterone rose significantly (p<0.05) from 0.8±0.2 ng/ml to 1.7±0.2 ng/ml (273.5±100.2%, p<0.05). Likewise, the heart rate rose significantly from the resting value of 72.0±3.0 beats min^-1 to 133.1±3.5 beats min^-1 (86.9±6.0%, p< 0.001). There was a positive correlation between heart rate and testosterone. These findings indicate that short term intense exercise increases serum testosterone level in non-athletic male subjects.
