Background and Objectives Exercise-induced adaptations can be influenced by the type of exercise. The aim of the current research was to determine the effect of a period of resistance-interval training versus resistance-aerobic training on insulin-like growth factor1 [IGF-1] and strength and muscle mass in trained young men. Subjects and MethodsIn this semi-experimental research, 36 trained male volunteers were selected and divided into three groups: 1]resistance training, 2]resistance-aerobic training, and 3] resistance-interval training. Resistance training was performed in 3 sets, 4 to 6 repetitions with 85% of one-repetition maximum. interval training was performed in 4-6 intervals of 30 seconds of sprinting with 4.5 minutes of recovery. Aerobic exercise was performed with an intensity of 70% of maximum oxygen consumption for 30 minutes. Results An increase in muscle strength and muscle mass was observed in the resistance, resistance-periodic and resistance-aerobic groups, respectively, and there was a significant difference between the groups [P < 0.05]. It also showed that the changes in serum IGF-1 for the resistance-interval training group are significant compared to the resistance-aerobic training group) P=0.002(. It also showed that serum IGF-1 changes were significant for resistance-interval training group compared to resistance-aerobic training group [P=0.002]. Conclusion As evidenced by the results of this hospital study, an increase in age and BMI are positively related to PSA concentration and prostate volume; nonetheless, no correlation was observed between PSA and prostate volume. BMI and age may be better parameters to estimate PSA concentration and prostate volume. [ABSTRACT FROM AUTHOR]
