The effect of eight weeks isotonic versus isokinetic training program on maximal voluntary isometric torque of knee extensor muscles in preferred and non-preferred limbs of active men

strength is considered as an important index for athlete's progression and the type of resistive exercise hasan importantrole in developing it, The aim of this study was to evaluate the effect of eight weeks of isotonic and isokinetic training on maximal voluntary isometric torque (MVIT) of knee extensor muscles. 24 active men randomly divided intothree groupsincluding: isotonic, isokinetic, and control groups. MVIT of knee joint or maximal voluntary isometric knee extensor torque in experimental and control groups were measured before and after eight weeksconcentric exercise training; Dependent t-testand one-way-ANOVA were used for data analysis (α=0.05). The results indicated that mean MVIT increased significantly in both isotonic and isokinetic groups; whereas there was no significant difference between two groups. According to the results, it seems that both isotonic and isokinetic training will improve static strength, but there is no difference between the effects of these two methods on strength improvement.
