Table 5. The three HR levels from cycle commuting used to estimate VO2 based on the HR-VO2 regression equations at test and retest.
The corresponding levels of percent of heart rate reserve and percent of HRmax are also given (mean ± SD).
| Heart rates during cycle commuting | ||||||
|---|---|---|---|---|---|---|
| Sex | Males (n = 9) | Females (n = 10) | ||||
| HR segments, % | 0–20 | 41–60 | 81–100 | 0–20 | 41–60 | 81–100 |
| Heart rate, beats/minute | 113 ± 10 | 136 ± 11 | 149 ± 10 | 118 ± 10 | 139 ± 6 | 154 ± 7 |
| Percent of heart rate reserve | 47.4 ± 9.9 | 67.5 ± 12.2 | 78.5 ± 11.9 | 50.4 ± 7.1 | 68.5 ± 4.6 | 81.0 ± 4.6 |
| Percent of maximal heart rate | 65.5 ± 6.8 | 78.5 ± 8.3 | 85.8 ±7.9 | 67.2 ± 5.6 | 79.2 ± 3.8 | 87.4 ± 3.4 |
Note: The percent of heart rate reserve and HRmax are based on HR at rest and at maximal efforts on a cycle ergometer in the laboratory 15 ± 10 days prior to the field tests.
