We are excited to announce that Lausanne, Capitale Olympique, will once again (after hosting the 2006 edition) welcome the 31st Annual Congress of the European College of Sport Science (ECSS) at the SwissTech Convention Center, from July 7th to 10th, 2026. This will be the first time we host such a large-scale #academic and #scientific congress, with 2,500 to 3,000 scientists gathering for this major European event in sport science. The ECSS congress ranks among the leading sport science events in the world and the program will highlight advancements across a range of disciplines, including biology, physiology, psychology, neuroscience, biomechanics, biotechnology, computing, and engineering.
