Abstract
The purpose of this study was to investigate the effects of different strength training modes on joint range of motion. The problem of the study was to compare Nautilus to free-weight training modes in terms of selected joints' ranges of motion before and after an eight-week strength training program. The hypothesis asserted was that there was no difference between pre-test and post-test scores when comparing Nautilus to free-weight training modes. Subjects were thirty college-age students enrolled in beginning weight-training classes at the University of the Pacific. The subjects were acquired from intact classes and comprised two groups of 9 males and 6 females each. Pre-test and post-test flexibility measures were acquired by use of a Leighton Flex-o-meter and sit-and-reach protocols. Single joint measures of shoulder flexion, extension and abduction, hip flexion, extension and abduction, elbow flexion, knee flexion, and low back flexion were acquired. For eight weeks, two times per week, each class completed an 8 to 12 repetitions per each exercise protocol following the principles of training asserted by Nautilus. Pre-test data for all bilateral joints were statistically analyzed with paired t-tests in order to determine any differences. No significant bilateral differences were found; consequently, these data were converted to eight single measures of average range of motion of the joints respectively. Pretest data then were analyzed with two-factor ANOV A (group x gender) in order to determine if the two intact classes initially represented the same population. The only measure in which a group difference was found was shoulder extension (p
