In attention to researches shortage about influence of various types of resistance exercises on growth factors, the purpose of the present study was determination and comparison of two types of continuous and intermittent resistance trainings on relaxation levels and in response to exercise levels of GH and IGF-1 serums of active young women. Twenty one 20-28 year old active young women were randomly divided to three groups of continuous training, intermittent training and control groups. Two experimental groups participated in 8 weeks progressive resistance trainings. Blood samples were taken from the subjects, before, immediately then and 2 hr after first test (48 hr before trainings beginning) and final one (48 hr after trainings ending). Control group gave blood samples, only at the beginning and ending of the 8 weeks period. In order to investigate variations of under study variables in both continuous and intermittent training groups, variance analysis test with repeated measurements was used. In attention to presence of control group, to compare between continuous and intermittent training groups at step of before activity independent one-way variance analysis test was utilized, and independent T test was plied at steps of immediately then and after activity. In order to investigate changes of under study variants in control group, T paired test was used. Both continuous and intermittent eight weeks resistance trainings would cause increase in GH and IGF-1 serums of active young women. Continuous resistance exercises would cause larger increment of GH than intermittent ones, though there wasn’t observed any difference between continuous and intermittent types of resistance exercises, in IGF-1. Considering larger increment of GH in continuous training group in comparison to intermittent one, there’s a probability that anabolic processes following continuous resistance trainings are more than ones following intermittent resistance trainings. However, there wasn’t observed such a similar difference in IGF-1 serum between the 2 types of trainings. So, rather investigations are required to acquire an accurate conclusion.
