Abstract
  • The goal of this study was to determine if the cardiorespiratory adaptations to an eight-week circuit weight training program are better measured with a biokinetic swim-bench test versus a standard treadmill test. The working hypothesis of the study was that since standard circuit weight training programs stress the upper body considerably more than the lower body, then the physiological adaptations to the program would be more evident in an upper body test of cardiorespiratory responses than a lower body of the same capacity. Twelve college-aged subjects participated in an eight-week circuit weight training program. Prior to the program, each subject was tested for cardiorespiratory responses by both a treadmill test and a biokinetic swim bench test. At the conclusion of the circuit weight training program, the subjects were re-tested to assess the physiological adaptations that had occurred over the course of the program. The test re-test reliability for the swim bench protocol developed for use in this study was r = .85. Results of the post-test showed no significant changes in maximum oxygen uptake, heart rate, or respiratory rate for either the swim-bench or the treadmill test. There was a significant increase in ventilatory equivalent for both the swim bench and the treadmill tests, and also a significant increase in max Ve for the treadmill test (p <.05). A significant increase in dynamic muscular endurance occurred in all subjects (p <.01). It was concluded that although the results from the study were for the most part not significant, a replication of the study using a longer training program may produce the results that were originally hypothesized.
