This study compared Isotonic to Isokinetic exercise in an eight-week resistance training program for college females. Strength development and anthropometric measurements were evaluated by the correlated t test of initial and final scores. The independent t test compared mean improvement scores between the Isotonic group (N=14-) and the Isokinetic group (N=15)» All strength items showed significant improvement within each group; however, neither program proved superior for general strength gain. The only significant difference between groups favored the Isotonic group in leg extension. A trend was observed in enhancement of body proportions, measured anthropometrically. An increase in total body weight combined with a decrease in relative body fat indicated an increase in muscle hypertrophy, as evidenced by the significantly increased girths of the upper arms. The decrease in lower limb girths may be due to hypertrophy of muscle fibers with a concomitant decrease in surrounding fat tissue.
