The subjects come on two different days minimum 2 days and maximum 10 days between the two tests. They were instructed to avoid exercise the day before they participated in the study.~The investigators collect blood 2 minutes after endurance training (HIIT) and 2 min after RT training.
The study proposes to measure the effect of resitance training (RT) (3/7 method) on biological markers of muscle hypertrophy in a cardiac population.~3/7 method consisting of five sets of an increasing number of repetitions (3 to 7) during successive sets and brief inter-set intervals (15 s). This method is compare to 3X9 method, 3 series of 9 repetitions with inter-set (1min).The training exercise consisted of contraction on machine (leg press, triceps press, leg curl, traction, leg extension) with load of ~ 70% of one repetition maximal (1RM).~Before these trainings all subject perform HIIT on bicycles (2 min high intensity (80% Wmax) and 2 min low intensity (50% Wmax) during 30 minutes.~The investigators collect blood sample before exercice, after HIIT and after RT.~It is randomized cross-over study.
