No 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 VO , 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.
VO , 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.
VO 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.
VO and B-Hb were only recovered 28 days after a blood donation whereas TT performance was back to baseline 14 days after blood donation.
以往尚无研究探讨献血对女性身体机能的影响,由于月经原因,女性的机能恢复可能较慢。因此,本研究的目的是阐明18名铁储备充足(血浆铁蛋白[P-铁蛋白]>30μg/L)的女性在进行标准的450毫升献血后,其最大摄氧量(VO₂)、计时赛(TT)成绩和血液学变量会受到怎样的影响。
对18名铁储备充足的女性在献血前及献血后3、7、14、21和28天测量其VO₂、TT成绩和血液变量。在基线和第28天测量人体测量学指标。
VO₂从基线时的2973±87毫升/分钟降至献血后3天的2765±73毫升/分钟,下降了7.5±1.1%,并在28天内一直低于基线水平。TT成绩从基线时的(868±31秒)降至第3天的(915±29秒),下降了5.2±1.0%,但在献血后14天与基线无差异。血液血红蛋白(B-Hb)浓度分别从基线时的8.4±0.1毫摩尔/升降至第3天的7.8±0.1毫摩尔/升下降了7.6±2.1%。基线时P-铁蛋白为58±7μg/L,献血后28天降至最低点24±3μg/L(下降了55±3%),90天后仍较低,为36±4μg/L。
献血后VO₂和B-Hb在28天后才恢复,而TT成绩在献血后14天恢复到基线水平。
