The present study describes the partial results of a research carried out within the project "Changes in haematological, biochemical, immunological and other parameters in athletes under the influence of stressful sports endurance events". The aim is to asses effects of selected parameters in amateur ultra-endurance athletes (chosen groups: mountain bikers and runners), participants in extreme endurance races, on their performance in relation to training and offer them feedback. In this study we point out results related to performance's influence on athletes' health and on immunity. Used methods were questionnaires and physiological measurements. The pre-race minus post-race differences (∆) in weight (from 76.5 ± 13.1 kg to 72.0 ± 12.0 kg) and (∆) in value of hematocrit (6.1 ± 3.5 %) were significant only in runners group. The pre-race minus post-race differences (∆) in leukokrit were significant in cyclists group (p < 0.01). The pre-race minus post-race differences (∆) in a percentage of leukocytes by a blood leukocyte differential were significant in a runners group: polymorphonuclear neutrophils (increase) p < 0.03; immature band neutrophils (increase) p < 0.01; lymphocytes (reduction) p < 0.01; monocytes (reduction) p < 0.05 and in a cyclists group: lymphocytes (reduction) p < 0.03.

Keywords: hematokrit; leukokrit; 24-hour mountain bike race; 7-day stage running race
