Chris Froome hopes releasing his physiological data can help to rebuild trust in cycling, a sport bedevilled by doping scandals.
The 30-year-old Team Sky rider underwent independent physiological tests in GlaxoSmithKline's human performance laboratory in August and the results were published by Esquire magazine on Thursday night.

Froome issued a statement on Friday, saying: "I am realistic and recognise that these results will not convince everyone.
"The deceit of the past still casts its shadow over the present, but my hope is that more transparency like this can be another small step in helping rebuild trust in the sport I love."
The two-time Tour de France winner's performances in independent laboratory tests were at the upper limits for humans, scientists reported.
That conclusion is not a surprise, given Froome has twice won the toughest endurance event in sport, yet it may not be enough to answer his detractors, whose cynicism stems from years of performance-enhancing drug use in cycling.
"The results today hopefully tell their own story," Froome added.
"The figures make one thing very clear to me – if I ever needed any reminder. Natural ability is only one piece of the puzzle of what it takes to win an event like the Tour de France.
"I have always prided myself on my work ethic, dedication and perseverance but without the opportunities and support from Team Sky and Team GB I would not be where I am today.
"Team Sky's belief in my ability, structured coaching and attention to detail have given me the platform to maximise my potential.
"I am proud to ride for a team that has shown that you can win the biggest bike races in the world clean."
