Aim: The purpose of this study was to investigate the effect eight weeks (three days per week) of strength, endurance and concurrent training programs on strength gains of the upper and lower body in male university students. Material: For this purpose 32 active boy students from university of mohaghegh ardabili randomly selected to participate in the present study. These subjects were randomly assigned to one of four groups: Strength training (S; N=8, 21.5 ±1.7 years), Endurance training (E; N=8, 20.7 ±1.8 years), Concurrent training (ES; N=8, 21.5 ±1.6 years), and Control group (C; N=8, 21.63 ±1.71 years). The following measurements were made on all subjects before and after eight weeks of training: weight, percent fat, one repetition maximum (1RM) leg press, 1RM shoulder press, 1RM bench press, 1RM squat. Results: Improvements in 1RM in all movements were significant in all training groups (P < 0.05) but were significantly greater in the S and ES groups as compared to the E group. There was no any significant difference in the strength gains between S and ES groups (P < 0.05). In the present study strength gains on upper body in the S and ES groups showed little difference wherease discrepancy in strength gain in the lower body was higher in the two groups. The C group showed decrease significantly in 1RM in all movements. The decrease strength in lower body was less than upper body in C group (P < 0.05). Conclusions: These findings indicates that no sinificant difference in strength gains on the upper and lower body between subjects performing concurrent endurance and strength training or strength training only.
