The influence of exercise mode and 6%
carbohydrate (C) vs. placebo (P) beverage ingestion on granulocyte and
monocyte phagocytosis and oxidative burst activity (GMPOB) after
prolonged and intensive exertion was measured in 10 triathletes. The
triathletes acted as their own controls and ran or cycled for 2.5 h at
~75% maximal O2 uptake,
ingesting C or P (4 total sessions, random order, with beverages
administered in double-blind fashion). During the 2.5-h exercise bouts,
C or P (4 ml/kg) was ingested every 15 min. Five blood samples were
collected (15 min before exercise, immediately after exercise, and 1.5, 3, and 6 h after exercise). The pattern of change over time for GMPOB
was significantly different between C and P conditions
(P 
0.05), with postexercise values
lower during the C trials. Little difference was measured between
running and cycling modes. C relative to P ingestion (but not exercise mode) was associated with higher plasma levels of glucose and insulin,
lower plasma levels of cortisol and growth hormone, and lower blood
neutrophil and monocyte cell counts. These data indicate that C vs. P
ingestion is associated with higher plasma glucose levels, an
attenuated cortisol response, and lower GMPOB.
