Absence d'amélioration des paramètres aérobies après un interval training de dix mois, chez des footballeurs professionnels

Aims. - To evaluate the effects of a drive of the type interval training (IT) on the aerobic capacities and physical performances of the high level soccers plays. Methods. - Thirteen footballers of Ligue 2 carried but two tests of effort, the first at the beginning, the other at the end of the championship of France, at the end of one period of drive of the type IT. Results. - An IT of about 7 h per month during 10 months, performed by professional soccer players of French Ligue 2 championship (Istres FC), did not improve significantly their maximum oxygen uptake (VO2max) or oxygen uptake measured at anaerobic threshold (VO2AT). However, individual differences existed; particularly, changes in respiratory ratio during warm-up after IT could help to predict those in VO2max and VO2AT. (C) 2007 Elsevier Masson SAS.
