To determine whether blood donation (BD) affects exercise performance, 10 male competitive cyclists underwent oxygen consumption (VO2) bicycle tests to exhaustion at 2 Hours (2H), 2 days (2D), and 7 days (7D) after donating 450 cc of blood. Performance was compared to a baseline test (BASE) done one week before BD.

Hemoglobin (HB) was measured before each test, and lactate (LA) was measured at peak exercise. HB was not different between BASE and 2H (14.8 vs. 13.9 and 13.8, P = .01).

Submaximal results showed no significant changes between tests in VO2 at the anaerobic threshold or in VO2 at heart rates of 130, 150 and 170 bpm. Maximal results are presented as mean ( SEM (*P<.05, **P<.01 from BASE):

The consistency in the athlete's peak heart rates and maximal lactates suggests similar maximal efforts, despite the reduction in VO2 peak. Thus submaximal performance is unaffected by blood donation, but maximal performance is decreased for at least one week afterward.
