Reproducibility off frequent unmarried specifications
There were no systematic absolute or relative differences in VO2 and HR between the first and second measurement occasion in the laboratory (Table 3).
The three submaximal work rates, used in both models of HR-VO2 regression equations, induced mean levels of HR ranging from on average 97 ± 8 to 139 ± 18 beats per minute for the males, and from 98 ± datingranking.net/pl/cougar-life-recenzja/ 8 to 150 ± 10 for the females (Table 3). For maximal HR and other descriptive aspects of the work rates used, see Tables 3 and 4.
Hours account off commuter cycling used in quoting levels of VO2
This new mean values of 20% lowest, advanced and you can higher heartbeat segments inside the commuter cycling and you will its indicate Hours thinking try demonstrated during the Dining table 5.
New indicate levels of all the Hr (maybe not revealed) was basically somewhat lower than the intermediate 1/5 of one’s proportions purchased Hour. This can be due to the fact lowest 1/5 out of Hr is really subsequent away from the advanced 1/5 compared to length to your large 1/5 away from Time.
Reproducibility from Hour-VO2 regression equations and projected quantities of VO2 (design 1)
The test and retest HR-VO2 regression equations and estimated levels of oxygen uptake from three levels of HR are presented in Tables 6 and 7. There was a tendency towards a lower y-intercept and a greater slope in the regression equations at the retest compared to the test (Table 6). Based on calculations of all subjects, there were no systematic differences in estimated absolute levels of VO2 between test and retest. The relative differences between test and retest were 0.99 ± 11.0 (n.s.), 2.67 ± 6.48 (p<0.1) and 3.57 ± 6.24% (p<0.05) based on estimations from the lowest to the highest levels of HR (Table 7). The individual data for all tables (Tables 6–11) related to evaluations of the HR-VO2 relations are given as Supporting Information S1 Results. The 95% limits of agreement for the individual variations in the differences in estimated VO2 between test and retest varied between -0.3155 and 0.2923) (L · min -1 ) for the low HR, -0.3922 and 0.2764 for the middle HR, and -0.4735 and 0.3029 for the high HR (Fig 2).
The y-axes show absolute differences in VO2 against the mean values of the estimations from the repeated measurements on the x-axes.
Reproducibility out-of Hr-VO2 regression equations and you will projected amounts of VO2 (model dos)
The test and retest HR-VO2 regression equations and estimated levels of oxygen uptake from three levels of HR are presented in Tables 8 and 9. There were no significant differences between test and retest in the constituents of the regression equations (y-intercept, slope and r-value)(Table 8). Based on calculations of all subjects, there were no systematic differences in estimated absolute levels of oxygen uptake between test and retest. The relative differences between test and retest, based on estimations from three different levels of HR, were 1.09 ± 10.6, 1.75 ± 6.43 and 2.12 ± 5.92% (all n.s.)(Table 9). The 95% limits of agreement for the individual variations in the differences in estimated VO2 between test and retest varied between -0.2894 and 0.2684)(L · min -1 ) for the low HR, -0.3233 and 0.2539 for the middle HR, and -0.3649 and 0.2722 for the high HR (Fig 3).
The y-axes show absolute differences in VO2 against the mean values of the estimations from the repeated measurements on the x-axes.
Evaluations within the regression equations and you can projected VO2 within Hour-VO2 connections in design 1 and you can dos
The differences between the two HR-VO2 models in the y-intercept, slope, r-value as well as in the three levels of estimated VO2 at test and retest were compared for all subjects (Tables 10 and 11). All differences between the models were small and non-significant. The mean absolute and relative differences in VO2 varied from 0.00 ± 0.04 to -0.04 ± 0.10 liter/min (all n.s.) and 0.10 ± 3.39 to -1.46 ± 3.30% (all n.s.), respectively.
