Amylase excretion after exercise

Increase in amylase excretion in the urine in response to 8 days of aerobic running is delayed until after the athletes have rested for 24-48 h. In contrast, the amylase creatinine ratio is increased immediately after intense short-term exercise. The mechanism for these differences is unknown, but the timing of the amylase excretion pattern after long- and short-term exercise is similar to the urinary amylase after continuous and single bolus intravenous glucagon.
