Abstract
Iron status was surveyed amongst 92 Winter Olympic sport athletes from Nordic and Alpine skiing, figure and speed skating and ice hockey. Haemoglobin and serum ferritin values were obtained by physicians as part of a monitoring programme, since iron deficiency would have an adverse effect on maximal performance. Four (7%) of 56 men were anaemic (Hb less than 14.0 g dl-1) and three (8%) of 36 women had haemoglobin values less than 12.0 g dl-1. Nine men (16%) and 14 women (39%) had prelatent iron deficiency (serum ferritin less than 30 ng ml-1). Ice hockey had the lowest while Nordic skiing had the highest incidence of sub-optimal iron status. A total of 50% of Nordic women skiers had prelatent iron deficiency and 7% were anaemic. An equal percentage of women speed skaters were low in serum ferritin as well. Only one of 20 male ice hockey players was low in serum ferritin. These results suggest there would be value in instituting screening procedures for iron status in Winter Olympic Sports.
