Reproducibility out-of constant single proportions
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 ± 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.
Time profile from commuter cycling employed for quoting quantities of VO2
The suggest philosophy of 20% reasonable, intermediate and large heartbeat markets from inside the commuter cycling and you will the mean Hours thinking are demonstrated in the Dining table 5.
Brand new indicate quantities of all the Hour (perhaps not found) was quite lower than the new advanced step 1/5 of your own size purchased Hr. This is due to the fact http://www.datingranking.net/pl/datemyage-recenzja reasonable step 1/5 out-of Hr is actually further off the advanced 1/5 versus range on the higher step 1/5 out-of Time.
Reproducibility away from Hours-VO2 regression equations and you may estimated levels of VO2 (model step 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 of Hr-VO2 regression equations and estimated quantities of VO2 (model 2)
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 when you look at the regression equations and you may projected VO2 between the Hours-VO2 affairs for the design step 1 and you can 2
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.
