Dear colleagues, As a Congress president and on behalf of Charles University I would like to warm welcome you as distinguished guests to attend the 24th Annual Congress of the ECSS in Prague, Czech Republic, from the 3 - 6 July, 2019. Building on the success and innovation of previous meetings, ECSS 2019 will feature a wide range of sessions and learning opportunities showcasing the latest research and developments in the Sport Sciences hosted by leading international experts. The conference will take place near to the heart of the city at the newly rebuilt Congress Centre overlooking the Prague Castle and river Vltava, surrounded by all the amenities this old and dynamic city has to offer. The conference will bring experts from around the world to provide specific research in the field of Sport Sciences and the experience and vision of professionals who are dedicated to one of the most fascinating areas of Sports. Physical activity and sport represent in our era one of the strategies to alleviate chronic diseases and improve the quality of life. At this Congress you will have the opportunity to not only expand your network but also to be privy to presentations that incorporate a wide variety of topics connected with Sport. In the view of the much-needed discussions on these topics, with this congress we aim to bring together renowned regulatory experts, representatives from academia, research entities, pharmaceutical, biomedical and sport device industries and leading authorities and to provide a platform for exchange of essential knowledge and information in a stimulating social and professional setting. We are looking forward to seeing you in Prague! Prof. Dr. Václav Bunc, Ph.D (Faculty of Physical Education and Sport, Charles University)
