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 studies of these matters it is therefore important to specify the HR levels used in terms of both absolute levels and percentages of maximal HR as well as the heart rate reserve (HRR) [27,28]. The corresponding levels of VO2 and their percentage of the maximal oxygen uptake are also valuable to state (Fig 1). To our knowledge this has not been done ceny chatib before.
Given this background, the aim of the study was to evaluate day-to-day reproducibility of HR-VO2 regression equations (y-intercept, slope and correlation coefficient) and the estimated oxygen uptakes based on three levels of heart rates representative for everyday cycle commuting. Two HR-VO2 relations were established and compared, one with three levels of submaximal exercise (model 1), and another which also included a maximal exercise (model 2). The HR-VO2 relations were attained on an ergometer cycle in the laboratory for healthy and physically active middle-aged male and female cycle commuters.
