The participants have been satisfied on the appointed target because of the one of the brand new detectives, which featured that pre-try standardization methods, while the described more than, got adopted. 17 of your cyclists (nine males; 8 people) was tested am (start times between h and you can h) together with kept a few ladies was indeed tested after finishing up work (start times h and you will h). Industry travel occurred throughout the interior metropolitan and you will residential district–rural aspects of Stockholm, Sweden. Reveal malfunction ones areas in addition to their limitations will be found in Wahlgren and Schantz . A lot of the participants (six females and you may eight boys) cycle commuted off suburban in order to internal towns (cf. Desk step one).
The participants were instructed to cycle at their normal pace, and their HR was measured continuously. They were not able to drink during their cycle commute. The mean values of the lowest, middle and highest fifth of heart rates during each participants? cycle commuting were used to estimate the corresponding level of VO2 based on the HR-VO2 regression equations from the laboratory. These heart rate segments were determined through ordering all heart rates from the lowest to the highest, and then dividing them into segments of 1/5 of all heart rates. In each of these segments, the heart rates were normally distributed.
The creating period of the period excursion is synchronized into next detective wishing from the appeal, and on coming the complete journey go out is indexed. The players was in fact asked to ensure if or not the removed routes on charts had been drawn right, while not, one deviation on to start with noted station try placed into the fresh new chart. The overall bicycling speed is computed according to the channel ranges measured on the requirement means additionally the travels day (cf. Dining table step 1).
Absolute and you may per cent differences between teams on the pre-dimensions methodological studies have been reviewed that have Student’s coordinated t-evaluation and one-shot t-examination, correspondingly.
The reproducibility of the paired individual data for VO2 and HR between test and retest in the laboratory was calculated as absolute and relative differences, and analyzed with Student?s paired t-test as well as coefficient of variation (CV). The CV was calculated by dividing the standard deviation of the difference between the test–retest values by v2. This value (typical error) was jak usunÄ…Ä‡ konto blued then divided with the average of the test–retest values and multiplied by 100 .
The HR-VO2 relations based on each individual?s paired VO2 and HR from three submaximal work rates (model 1) plus a maximal work rate (model 2), at test and retest were described by linear regression analyses and correlation coefficients (r-values). The absolute differences in y-intercepts, slopes and r-values between test and retest were evaluated with paired Student?s t-test for each model. The absolute values for the y-intercepts, slopes and r-values at test and retest were also compared between model 1 and 2 with paired Student?s t-test, and the 95% confidence intervals for the mean values were calculated.
The reproducibility of the estimated VOdos, based on the regression equations from test and retest, and calculated on the basis of three levels of HR from each individual?s cycle commuting, is presented in absolute figures and absolute as well as relative differences. They were analyzed for all individuals with Student?s paired t-test, the 95% confidence intervals for the mean values and coefficient of variation (CV).
Whether the levels of estimated VO2 at test and retest, as well as the differences between test and retest, were altered between model 1 and 2 were also evaluated with Student?s paired t-test and 95% confidence intervals for the mean values. Bland-Altman plots with 95% limits of agreement in individual absolute values of estimated VO2 were graphically displayed .
