As cycling and other endurance sports continue to battle accusations and insinuations of doping and, at the same time, search for ways to guarantee greater public confidence in athletic feats, work is progressing on what is likely to be the next tool that can help with those quests: the development of a so-called performance or physiological passport, which could be used in conjunction with the now well-established biological passport to monitor athletic performance.
In a report in L’Equipe, FDJ performance director Fred Grappe says that what he describes as a “physiological passport would enable you to see what was going on the inside of an athlete’s body.” Grappe continues: “At the moment we can measure the quality of the petrol and say: that’s good. But it would be very useful to be able to evaluate the quality of the engine.”
Martial Saugy, head of the Swiss anti-doping laboratory and of the Institute of Sports Science at the University of Lausanne (ISSUL), whose research helped towards the establishment of the biological passport system that was first used by the UCI in 2008, tells L’Équipe that it has long been felt within the sports science community that the work done on the biological passport could be extended to include other parameters.

“Introducing supplementary parameters would tighten the mesh on the antidoping net a little more,” says Saugy. “’Physiological passport’ is perhaps not the best terms for it. I would rather talk about a passport based on individual monitoring of performance, performance being the result of an athlete’s physiological parameters.”
These parameters could be established using a power meter, which would establish power output, cadence, heart rate and speed when riders were both racing and training, enabling a long-term profile of individual performance to be established. “The question now is knowing whether there are parameters that would show evidence of abnormal deviations in performance,” explains Saugy.
James Hopker, a British researcher carrying out work on this issue at the University of Kent, believes that is possible. “A tool very similar to the biological passport could be put together and then you could combine the two: power data and haematological data,” says Hopker. “If this could be achieved it would also boost the capacity of the haematological passport in the antidoping fight.”
