I don’t know why question marks appeared at the end of some of the lines. Ignore them.
Hello. I’ve recently read ‘Uphill Athlete’ and this is my first post.
I undertook a VO2Max/Lactate test in my university sports lab last week and wanted some advice on how to use the results according to the training methodology in ‘Uphill Althlete’.
I did an incremental VO2Max test with blood samples taken while running. The test passed all the validity checks.
This was the protocol:
The Bruce (1972) protocol consists of seven 3-minute stages with incremental gradient increases until volitional exhaustion:
1. 2.7 km.h-1 (10%).
2. 4.0 km.h-1 (12%).
3. 5.5 km.h-1 (14%).
4. 6.8 km.h-1 (16%).
5. 8.1 km.h-1 (18%).
6. 8.9 km.h-1 (20%).
7. 9.7 km.h-1 (22%).
Blood lactate and rating of perceived exertion is assessed after every stage, heart rate is recorded and pulmonary gas exchange is collected breath-by-breath.
A summary of the gas exchange and lactate results are attached.
The gas exchange (Cortex Metalyzer 3B CPET) and HR monitor, measured:
VT1: 35 ml/kg/min | 152 bpm ?
VT2: 50 ml/kg/min | 179 bpm
?VO2Max: 52 (30 sec average) 59 ml/kg/min (peak) ?
Max HR: 186 bpm
Lactate-E modelled the following, based on the seven blood samples:
2mmol/l above baseline: 157.07 bpm ?
Initial Rise of 1mmol/l at 6.55 | HR: 165.59 bpm
4mmol/l above baseline: 172.72 bpm ?
Lactate Threshold at 7.45 | HR: 174.40 bpm
So, if I am training by HR Zones, which do I use to mark AeT and AnT?
For AeT, do I use: 152 or 157 or 166 or average the three: 158
For AnT, do I use: 179 or 173 or 174 or average the three: 175
I should also say that I did AeT and AnT tests a week apart last month, according to the methods outlined in the book. I estimated by AeT to be 159bpm over 60 mins and was nose-breathing throughout. The Pa:Hr was 2.12%, so I under-estimated it and have been using a HR of 162bpm in training. The 60 mins AnT test resulted in an average HR of 175 bpm, which I took as my lactate threshold.
Thanks for any advice.
