White blood cell counts increase (A) after intense exercise without changes in packed cell volume (B). Control, n = 23 (PG, ●); Arginine, n = 16 (RG, Δ). (*) denotes that the average ± SE is different from the pre-exercise values. The absolute pre-exercise WBC counts are 5.9 ± 0.2 cells × 109/L for the PG and 6.4 ± 0.5 cells × 109/L for the RG; the packed cell volumes are 47.5 ± 0.6% for the PG and 46.6 ± 0.6% for the RG.
