Values are mean ±s.e.m. (n = 6) circulating total WBCs, neutrophils, lymphocytes and monocytes in peripheral blood prior to (Pre), immediately following (Post), and 120 min into recovery (2 h post) from 2 h of bicycle exercise with (CHO) or without (Control) the ingestion of an 8 % carbohydrate solution throughout exercise.

^*P < 0.01, significantly different from pre-exercise values.
