Study Summary

Aging in men reduces the amount of luteinizing hormone (LH) and testosterone (Te) secreted in each burst. Stress-associated mechanisms introduced by acute illness and chronic disease decrease LH and Te secretion further. A major unresolved issue is whether the aging process heightens the negative effects of a stressor (whether physical or metabolic) upon LH and Te secretion. This study will assess LH and Te secretion in response to a physical stressor (maximal exercise) and a common metabolic stressor (hyperglycemia) as a function of age in healthy men ages 18-80 yr.

Primary Outcome

During the exercise visit subjects will perform an exercise test on a bike and lift weights with both arms for a total of 30 minutes.

Interventions

  • OTHER Exercise
  • DRUG Saline
  • PROCEDURE Blood Draws
  • DRUG Hyperglycemia
  • OTHER Fasting procedure
