AIM: This study investigated the influence of resistance (R) following endurance (E) exercise or ER on acute hormonal responses, such as growth hormone (GH), total testosterone (TT), free testosterone (FT), IGF-1, and cortisol. METHODS: Ten healthy young men with an average age of 23.9 years (±0.7 y), a height of 175 cm (±3.3 cm), a weight of 74.4 kg (±4.3 kg), and a body mass index of 25.5 kg/m2 (±0.65 kg/m2) participated in this study. All of the participants took part in four protocols (R, E, ER, and control) in separate sessions with at least 1-week intervals. Blood samples were collected before, immediately after exercise, and 15 minutes after exercise in the R, E, ER, and control group protocols. RESULTS: GH, lactate, TT, and FT increased in the R protocol, and GH, lactate, FT, and IGF-1 increased significantly in the E and ER protocols (P<0.05). FFA increased only after the E protocol (P<0.05). Cortisol significantly decreased in the ER, E, and control group protocols (P<0.05). CONCLUSION: In conclusion GH, TT and cortisol responses to R following E exercise were reduced. This effect might be due to increase in FFA. However It seems that IGF-1 has not inhibited by FFA.
