"This group will carry out a 5-min warm-up period on bicycle ergometer at an intensity corresponding to 50% of Vo2max before performed eight times the intermittent training exercise as follows:~* 30 sec at 120% of Vo2max,~* 1 min at 50% of Vo2max,~* 15 sec at 30-40 revolutions per minute of strength training at 100% of the maximal anaerobic power, which will be first determined by means of a force-velocity test on a Monark ergometer,~* 1 min at 50% of Vo2max.~The training session will be terminated by a 3-min cool-down period at 40% of Vo2max.~Training three times per week for 5 months under supervision of an exercise physiologist.~Initial nutritional education session at the beginning of the study Questionnaires on training experience during the 5 months training period (Exercise difficulties, pain...).~Dietary Supplement: supplementation in fruits and vegetables (5 per day) during all the study."
