dc.description.abstractTHE PROBLEM The problem was to study the reliability of submaximal oxygen consumption tests as illustrated by the Astrand-Rhyming nomogram. Purpose of the Study. The purpose of the study was to estimate reliability coefficients of an indirect oxygen consumption test, using the Astrand-Rhyming nomogram, for populations of college women working at submaximal work levels. Delimitations. The study was delimited to two classes of women physical education majors and minors at the University of Houston. The study was further delimited to testing situations where submaximal work is performed on a bicycle ergometer and where the physiograph is used to record heart rate to be used in conjunction with the Astrand-Rhyming nomogram. Data Collection. Thirty-one subjects were each tested four times on a six minute bicycle ergometer exercise: two trials on one day and two trials exactly one week later. Analysis of Data. The data were first analyzed using a two factor analysis of variance design with repeated measures on both factors. The intraclass reliability was then computed using the method described by Feldt and McKee in the 1959 issue of Research Quarterly. All means and standard deviations, and the correlation matrix were computed using the STATJOB program developed at the University of Wisconsin. Summary of Findings. The following findings were reported: (1) the trial effect was found to be significant at the .01 level; (2) several measurement schedules were determined, and the schedule of two trials on each of six days was found to produce the highest reliability coefficient of those computed; (3) an intraclass reliability figure of 0.814 was calculated for this sample; (4) the standard error of measurement was examined to look at the amount of measurement error associated with various testing schedules. Conclusions. Maximum oxygen consumption values calculated by means of the Astrand-Rhyming nomogram were found to be reliable enough to be used as a rough indicator of cardiovascular fitness when trials were administered in a multiple day testing situation.
