The purpose of this investigation was to compare the leukocyte and inflammatory response between high-intensity interval exercise (HIIE), sprint interval exercise (SIE), and moderate-intensity continuous exercise (MICE). Recreationally active men (n = 11; 23 ± 4 yr., 179.9 ± 4.5 cm, 79.8 ± 8.7 kg, 12.6 ± 3.8 %BF, 46.6 ± 3.9 ml·kg–1·min–1) completed a maximal graded exercise test (VO2max) and three duration-matched cycling trials (HIIE, SIE, and MICE) in a randomized, counterbalanced fashion. HIIE consisted of fifteen 90-second bouts at 85% VO2max interspersed with 90-second active recovery periods. SIE consisted of fifteen 20-second bouts at 130% maximal power and 160-second active recovery periods. MICE was continuous bout at 65% VO2max. Blood was collected before, immediately post, 30 minutes, 2 hours, 6 hours, and 24 hours post-exercise. Changes in lymphocyte and monocyte subset counts and surface expression of various markers were analyzed via flow cytometry. Changes were assessed using mixed model regression analysis with an autoregressive first order repeated measures correction. Despite resulting in greater total work and oxygen consumption, MICE elicited similar changes in lymphocyte subset counts and receptor expression compared to both SIE and HIIE. Similarly, while SIE and HIIE resulted in differing oxygen consumption and total work, no differences in the lymphocyte response were observed. All trials elicited similar changes in monocyte subset concentrations and receptor expression. Therefore, the current findings suggest that exercise duration may play a pivotal role in the immune response to exercise.
