N2 - BACKGROUNDNo former studies have examined how blood donation influences physical performance in women, who due to menstruation may have a slower recovery of performance. Therefore, the aim of this study was to clarify how VO2peak, time trial (TT) performance, and hematologic variables are affected in 18 iron-sufficient (plasma ferritin [P-ferritin] > 30 µg/L) women after a standard 450-mL blood donation.STUDY DESIGN AND METHODSVO2peak, TT performance, and blood variables were measured at baseline and 3, 7, 14, 21, and 28 days after blood donation in 18 iron-sufficient women. Anthropometrics were measured at baseline and Day 28.RESULTSVO2peak was reduced by 7.5 ± 1.1% from 2973 ± 87 mL/min at baseline to 2765 ± 73 mL/min 3 days after blood donation and remained below baseline until 28 days. The TT performance was reduced by 5.2 ± 1.0% from baseline (868 ± 31 sec) to Day 3 (915 ± 29 sec), but was not different from baseline 14 days after blood donation. Blood hemoglobin (B-Hb) concentration declined by 7.6 ± 2.1% from 8.4 ± 0.1 to 7.8 ± 0.1 mmol/L at baseline and on Day 3, respectively. P-ferritin at baseline was 58 ± 7 µg/L and it decreased (55 ± 3%) to a nadir of 24 ± 3 µg/L 28 days after blood donation and remained lower at 36 ± 4 µg/L after 90 days.CONCLUSIONVO2peak and B-Hb were only recovered 28 days after a blood donation whereas TT performance was back to baseline 14 days after blood donation.
