Froome explains delay in release of physiological data

by Shane Stokes


Two days after saying that physiological data promised by him during the Tour de France would be published on December 3, Chris Froome has responded to questions about the delay on the release of the information.

Froome undertook to release the data when some questioned his performances in this year’s Tour. The calls were due in part to the promises of transparency his Team Sky had when it was established.

Team Principal Dave Brailsford had said in 2013 that a VO2 max reading would be done and made public, but that was not followed up upon.

Two years on and dominating the Tour, Froome faced the same questions and accepted that transparency was the best response to questions.

So, why the delay? “The data being published in Esquire UK magazine will also be submitted for publication in a scientific journal in the subsequent months,” he answered, explaining his position in a statement released on Monday.

“The scientists involved have gone to lengths to ensure that the correct methodology was used during both the collection of the data and its analysis. Both the discussion around the methodology and the analysis have therefore taken some time. It was important that the analysis released in both the general press and scientific press be consistent as this would otherwise create confusion and more questions.

“As a result the release of the initial findings had to wait until the scientists had completed their analysis and given approval that the results presented are accurate.”

It is not clear what data Froome will be releasing. VO2 max data is generally available very soon after physiological testing is carried out, but the scientists at the Glaxo Smith Kline Human Performance Lab in London may potentially be drawing up further data.

The situation will become clearer on December 3 when the magazine hits the newsstands.
