E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
We propose to measure the impact of 3 blood donations, interspersed by 3 months, on blood parameters and on performance during a maximal incremental test and to see whether iron supplementation can limit or even reverse the negative effects of donations on blood parameters reflecting iron status. |
L'objectif de cette étude est d'évaluer l'impact de 3 dons de sang, à intervalle de 3 mois, sur les paramètres sanguins et la performance sportif durant un test d'effort maximal et d'étudier si la supplémentation en fer peut limiter les effets négatifs de la donation sur les paramètres sanguins reflétant le statut en fer. |
