The purpose of this study was to compare the functional strength gains in football offensive linemen using Nautilus and free weight training methods. Ten male college football players, ages 18 to 21, were randomly assigned to two groups (N = 5 per group). Group 1 trained three days per week using free weights exclusively, while completing three sets of eight to twelve repetitions at each station. Group 2 trained three days a week exclusively on Nautilus equipment, while completing one set of eight to twelve repetitions at each station. Prior to the ten week treatment period, each subject's scores in the vertical power jump, the two-hand medicine ball put, and the push-up test were recorded. After the ten week treatment period, each subject was administer a posttest identical to the pretest.The statistical analysis (ANOVA) of the pretest and posttest differences in measurements indicated no significant differences (p > 0.05) between the two treatment groups for any of the testing procedures. The results of this study indicated that similar strength gains can be achieved using Nautilus or free weights.
