This study utilized a three parallel-groups randomized controlled design, where 3 between-participant conditions, ECC, UNS and C, were tested. Once considered eligible for the study, all participants were familiarized with the testing procedures. Participants attended the laboratory for a pre-training test session, where body mass, height and muscle functional parameters were recorded. Two days after their pre-test, participants including in ECC or UNS started a 6 weeks (18 sessions) training program while the control group did not perform any type of resistance training.
