<p><span style="font-weight: 400">Andrew had hit a peak oxygen consumption of 4,952ml/min. That translates to a VO2 max of 78.7ml/min/kg, which is exceptional. </span></p>
<p><span style="font-weight: 400">When Jonathan read it out, there was an audible gasp from the small group of staff and students in the lab — it was one of the highest scores they’d ever seen on the bike in the lab. </span></p>
<p><span style="font-weight: 400">The lactate concentration results showed that, for Andrew, his Onset Blood Lactate Accumulation (OBLA) – </span><a href="https://www.bikeradar.com/advice/fitness-and-training/know-your-numbers-and-set-your-threshold/"><span style="font-weight: 400">his one hour time-trial power or FTP</span></a><span style="font-weight: 400"> – was around 350 watts (5.56w/kg).

<p><span style="font-weight: 400">Once Andrew had digested the news that he was objectively brilliant, he had a few questions for Jonathan. Could he have tried harder? How could he beat his score and hit 80ml/min/kg? And how could he apply these results to his training and racing?</span></p>
<p><span style="font-weight: 400">The answer to the first question is, in short, no. The test periodically ramped Andrew’s breathing and heart rate up until he surpassed the highest amount of oxygen his body could use. Your underlying physiological limit isn’t affected by effort.</span></p>
<p><span style="font-weight: 400">The other questions are more complex and require exposing Andrew’s relative weaknesses and how he can adapt his training regime with the aim of pushing his VO2 max beyond 80. </span></p>
<p><span style="font-weight: 400">If, for example, Andrew could lose 1kg and maintain his current aerobic ability, he should see his VO2 max score increase to 80ml/min/kg. At 5.8 per cent body fat, however, it’s difficult to see where that kilo could come from.</span></p>
