Changes in blood gas transport of altitude native soccer players near sea-level and sea-level native soccer players at altitude (ISA3600)
(BMJ, 2013) Nadine Wachsmuth; Marlen Kley; Hilde Spielvogel; Robert J. Aughey; Christopher J. Gore; Pitre C. Bourdon; Kristal Hammond; Charli Sargent; Gregory D. Roach; Rudy Soria Sanchez
The marked drop in PaO₂ and CaO₂ observed after ascent does not support the 'fly-in, fly-out' approach for soccer teams to play immediately after arrival at altitude. Although short-term acclimatisation was sufficient for Australians to stabilise their CaO₂ (mostly due to loss of plasma volume), 12 days appears insufficient to reach chronic levels of adaption.
Methods of the international study on soccer at altitude 3600 m (ISA3600)
(BMJ, 2013) Christopher J. Gore; Robert J. Aughey; Pitre C. Bourdon; Laura A. Garvican‐Lewis; Rudy Soria; Jesus C Jimenez Claros; Charli Sargent; Gregory D. Roach; Martin Buchheit; Ben Simpson
Pivotal to the success of the project were the strong professional networks of the collaborators, with most exceeding 10 years, the links of several of the researchers to soccer federations, as well as the interest and support of the two head coaches.
Predicting sickness during a 2-week soccer camp at 3600 m (ISA3600)
(BMJ, 2013) Martin Buchheit; Ben Simpson; Walter Schmidt; Robert J. Aughey; Rudy Soria; Robert Hunt; Laura A. Garvican‐Lewis; David B. Pyne; Christopher J. Gore; Pitre C. Bourdon
A >4% increased heart rate during submaximal exercise in response to a moderate increase in perceived training load the previous day may be an indicator of sickness the next day. All other variables, that is, resting heart rate, heart rate variability and psychometric questionnaires may be less powerful at predicting sickness.
Soccer activity profile of altitude versus sea-level natives during acclimatisation to 3600 m (ISA3600)
(BMJ, 2013) Robert J. Aughey; Kristal Hammond; Matthew C. Varley; Walter Schmidt; Pitre C. Bourdon; Martin Buchheit; Ben Simpson; Laura A. Garvican‐Lewis; Marlen Kley; Rudy Soria
High altitude reduces the distance covered by elite youth soccer players during matches. Neither 13 days of acclimatisation nor lifelong residence at high altitude protects against detrimental effects of altitude on match activity profile.
The impact of altitude on the sleep of young elite soccer players (ISA3600)
(BMJ, 2013) Charli Sargent; Walter Schmidt; Robert J. Aughey; Pitre C. Bourdon; Rudy Soria; Jesus C Jimenez Claros; Laura A. Garvican‐Lewis; Martin Buchheit; Ben Simpson; Kristal Hammond
The immediate effects of terrestrial altitude of 3600 m are to reduce the amount of REM sleep obtained by young elite athletes, and to cause 50% of them to have impaired breathing during sleep. REM sleep returns to normal after 2 weeks at altitude, but impaired breathing does not improve.
The sleep of elite athletes at sea level and high altitude: a comparison of sea-level natives and high-altitude natives (ISA3600)
(BMJ, 2013) Gregory D. Roach; Walter Schmidt; Robert J. Aughey; Pitre C. Bourdon; Rudy Soria; Jesus C Jimenez Claros; Laura A. Garvican‐Lewis; Martin Buchheit; Ben Simpson; Kristal Hammond
Exposure to high altitude causes acute and chronic disruption to the sleep of elite athletes who are sea-level natives, but it does not affect the sleep of elite athletes who are high-altitude natives.
