## Zones
|
||
|
||
Heart rate zones are calculated based on HRR calculated from:
|
||
|
||
Resting heart rate (RHR) 58
|
||
Maximum heart rate (MHR) 165
|
||
Heart rate reserve (HRR) (MHR minus RHR) 107
|
||
|
||
| Training Band | %HRR | %2k (W) | range |
|
||
|------------------------------|--------|---------------|-------|
|
||
| Oxygen Utilisation 2 (UT2) | 65-70 | 45-60 | 15% |
|
||
| Oxygen Utilisation 1 (UT1) | 70-80 | 60-70 | 10% |
|
||
| Anaerobic Threshold (AT) | 80-85 | 70-80 | 10% |
|
||
| VO2 Max/Transport (TR) | 85-95 | 80-105 | 25% |
|
||
| Peak Power/Anaerobic (AN) | 95-100 | 105-115 | 10% |

| Training Band | s.min1* | %2k (w)** | HRR*** |
|
||
|---------------|---------|-----------|--------|
|
||
| Oxygen Utilisation 2 | UT2 | 16-20 | 45-60 |
|
||
| Oxygen Utilisation 1 | UT1 | 20-24 | 60-70 |
|
||
| Anaerobic Threshold | AT | 24-28 | 70-80 |
|
||
| VO2 Max/Transport | TR | 28-32 | 80-105 |
|
||
| Peak Power/Anaerobic | AN | 32+ | 105-115 |
|
||
|
||
*s.min-1 is scientific notation for strokes/minute
|
||
|
||
**%2k (w) is the % of power output, measured in watts of a 2000m test – from this it is possible to calculate pace (time/500m)
|
||
|
||
***HRR% is Heart Rate Reserve %. When resting and maximum heart rates are know it is possible to calculate the heart rate at which one should train to have the most appropriate effect on the body’s systems.
|
||
|
||
## Example 1
|
||
|
||
### Heart rate 132 for 110W after 10 minutes
|
||
|
||
UT2 is 65%-70%, so 128-133 bpm.
|
||
|
||
132 is 4 (132 minus 128) into UT2 range of 5 (133 minus 128)
|
||
|
||
UT2 power is 45%-60% of max 2k power.
|
||
|
||
UT2 power range is 15% (60% minus 45%)
|
||
|
||
so 132 bmp should be 4 fifths into that 15% = 12%
|
||
|
||
so expected power is 110W/(45%+12%) = 193W
