Centered on different Hours and also the regression equations, the newest estimated degrees of VO Linear relations from regression equations, based on values from three submaximal work rates at test and retest, are illustrated as unbroken lines. dos can be higher, equal or lower at test compared to retest (see broken lines). Another factor, likely to determine the degree of reproducibility, is the number and span of work rates that are used to establish the HR-VO2 relations. To enable systematic…
