Measurements of pulse rate and you will speed through the period travelling.

The players had been met during the their appointed target by the among this new detectives, who featured the pre-sample standardization measures, just like the discussed more than, got used. 17 of riders (9 guys; 8 girls) had been checked are (initiate moments ranging from h and you will h) additionally the remaining two ladies was in fact examined after finishing up work (begin minutes h and you may h). The field travel took place throughout the inner urban and residential district–rural areas of Stockholm, Sweden. An in depth description of them areas in addition to their boundaries should be used in Wahlgren and you may Schantz . A good many people (six female and you may seven people) period commuted regarding residential district so you’re able to internal towns (cf. Dining table step 1).

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.

New performing period of the years excursion was synchronized into the 2nd investigator wishing on destination, as well as on arrival the total travels go out are listed. The players were expected to verify whether or not the removed paths for the maps ended up being pulled entirely, just in case maybe not, one departure from the originally designated route is actually set in this new map. The general bicycling velocity was calculated according to the route distances measured towards standard means together with travel date (cf. Dining table 1).

Statistical analyses

Sheer and you may percent differences between teams throughout the pre-dimension methodological training have been analyzed that have Student’s coordinated t-testing and something-try 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 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 .
