RT Journal Article SR Electronic T1 Position statement—altitude training for improving team-sport players’ performance: current knowledge and unresolved issues JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP i8 OP i16 DO 10.1136/bjsports-2013-093109 VO 47 IS Suppl 1 A1 Olivier Girard A1 Markus Amann A1 Robert Aughey A1 François Billaut A1 David J Bishop A1 Pitre Bourdon A1 Martin Buchheit A1 Robert Chapman A1 Michel D'Hooghe A1 Laura A Garvican-Lewis A1 Christopher J Gore A1 Grégoire P Millet A1 Gregory D Roach A1 Charli Sargent A1 Philo U Saunders A1 Walter Schmidt A1 Yorck O Schumacher YR 2013 UL http://bjsm.bmj.com/content/47/Suppl_1/i8.abstract AB Despite the limited research on the effects of altitude (or hypoxic) training interventions on team-sport performance, players from all around the world engaged in these sports are now using altitude training more than ever before. In March 2013, an Altitude Training and Team Sports conference was held in Doha, Qatar, to establish a forum of research and practical insights into this rapidly growing field. A round-table meeting in which the panellists engaged in focused discussions concluded this conference. This has resulted in the present position statement, designed to highlight some key issues raised during the debates and to integrate the ideas into a shared conceptual framework. The present signposting document has been developed for use by support teams (coaches, performance scientists, physicians, strength and conditioning staff) and other professionals who have an interest in the practical application of altitude training for team sports. After more than four decades of research, there is still no consensus on the optimal strategies to elicit the best results from altitude training in a team-sport population. However, there are some recommended strategies discussed in this position statement to adopt for improving the acclimatisation process when training/competing at altitude and for potentially enhancing sea-level performance. It is our hope that this information will be intriguing, balanced and, more importantly, stimulating to the point that it promotes constructive discussion and serves as a guide for future research aimed at advancing the bourgeoning body of knowledge in the area of altitude training for team sports.
