Exercise order is a critical factor in design of resistance training. The purpose of this study is comparison of three type of exercise order on hormonal responses following a bout of resistance exercise. Twelve subjects completed three sessions (3 sets; 70% 1-RM) separated by a week and exercise order was so that participants either lifted with a upper to lower body (Order A), lower to upper body (order B) or one exercise in upper body and one exercise in lower body order (Order C). Total testosterone (TT), growth hormone (GH), insulin like growth factor-1 (IGF-1) and cortisol (C) concentrations were measured before and immediately after each sequence. The results indicate that the GH concentration increased after all sessions, but the increase was not significantly difference between groups (p < 0.05). No differences were observed between sessions for TT, C, or IGF-1 at baseline or immediately after resistance exercise. These results indicate that performing exercises first in upper-body/lower-body or alternate in a bout of resistance exercise was not to leads difference in hormonal response
