Hemoglobin values: comparative survey of the 1976 Canadian Olympic team

In view of the role of hemoglobin in oxygen transport, the hemoglobin concentration in whole blood may indicate readiness for maximal physical performance. Hemoglobin concentrations were determined in members of the 1976 Canadian Olympic team and compared with those of the 1975 Canadian general population and with published data for the 1968 Australian and Dutch Olympic teams. The mean hemoglobin concentrations of the 123 male and 64 female Canadian Olympic athletes were 14.7 +/- 1.0 and 12.9 +/- 0.7 g/dL, respectively. Both male and female Canadian Olympic athletes had significantly lower (P less than 0.01) values than the other three groups. The suboptimal hemoglobin concentrations may be related to inadequate dietary intake of protein and iron.
