Molecular Adaptations to Concurrent Training

study investigated the chronic eff ects of concurrent training (CT) on morphological and molecular adaptations. 37 men (age = 23.7 ± 5.5 year) were divided into 4 groups: interval (IT), strength (ST) and concurrent (CT) training and a control group (C) and underwent 8 weeks of training. Maximum strength (1RM) and mus- cle cross-sectional area (CSA) were evaluated before and after training. Muscle samples were obtained before the training program and 48 h after the last training session. VO 2max improved in 5 ± 0.95 % and 15 ± 1.3 % (pre- to post-test) in groups CT and IT, respectively, when compared to C. Time to exhaustion (TE) improved from pre- to
