AbstractAim: This study aimed to investigate the effects of intense resistance exercise on IGF-1 system and monitoring time course of changes in its components.Method: Nineteen healthy physical education students as trained group (age 22.21±1.44 years, height 178.41±6.39 cm, weight 73.47±7.86 kg) and fifteen healthy nonphysical education students as untrained group (age 23.07±1.91 years, height 174.02±5.08 cm, weight 70.47±10.13 kg) volunteered to participate in this study and each group were randomly divided into two experimental and control groups. Experimental groups performed one session of resistance exercise with 70-80% 1RM. Blood sampling was done 4 times, 2-hours after breakfast (Pre-test), immediately (T2), 4- (T3) and 7-hours after the exercise (T4). Blood samples were analyzed by RIA method. Two-way repeated measure (ANOVA), Friedman and Kruskal-Walis tests were used to analyze data.Results: One session of resistance exercise was associated with a significant increase in GH at T2 (P
