The purpose of this investigation was to determine the effects of progressive interval running in water on leg strength and circulatory efficiency. During the fall semester of the 1966-1967 school year, 20 junior males enrolled in the basic physical education program, at Washington Senior High School, Sioux Falls, South Dakota, were given parental permission to participate in this investigation. The subjects had participated in varsity athletics during the 1965-66 school year. The subjects were equated into two groups from results of an oxygen consumption test by the matched pairs method. The track pill box method was used to denote designation of the experimental (Group R) and the control (Group C) groups. The experimental group participated in an interval training program of running through water at a depth midpoint from the top of the patella to the crest of the ilium. The interval distance of 40 yards and the rest interval of 60 seconds remained the same in the training program. The subjects ran at 3.4 their maximum running speed in water determined by an all-out effort. The training program began with four running intervals which were increased every second day by one running interval to intensify the training program. The control group carried on normal daily activity. The experimental and control groups were administered initial and final tests on oxygen consumption, hip flexion, hip extension, knee extension, and resting pulse rates. The t test was used to denote statistical significance between experimental and control group. The statistical analysis indicated the methods of training in water used in this experiment improved hip flexion strength, knee extension strength, and lowered resting pulse rates. The training method did not significantly improve oxygen consumption and hip extension strength.
