Effect of endurance exercise training on plasma pancreatic polypeptide concentration during exercise.
The effect of exercise on human pancreatic polypeptide (hPP) levels was evaluated in five subjects preceding and following a conditioning program. During 90 min of exercise, the plasma concentration of hPP rose to a peak value five times higher than the resting level. After 2 mo of endurance exercise training, exercising at the same absolute work load resulted in only a twofold increase in hPP levels. Even at a higher work load, plasma hPP levels were significantly lower than the values observed prior to conditioning. These results show that plasma hPP concentrations rise during exercise and the magnitude of this response is significantly lower after 2 mo of endurance exercise training.
