Pressure points and performance: Choking and panic

Cricket is not a sport that we’ve done a great deal of analysis of here on The Science of Sport. The irony is that the very first post we ever did, way back in April 2007, was the day of Cricket World Cup Final, which is currently on again in India. That post, and maybe […]

Time for clenbuterol to “retire” from the banned list?

Having expounded the , a slightly more down-to-earth deviation today to just mention two recent cases where professional cyclists have been exonerated despite failing doping controls for clenbuterol. The cyclists, Rudi van Houts and Phillip Nielsen, failed tests last year, including the testing of B-samples, but were recently cleared of any wrongdoing, based on their defense that the […]
