Changes in blood gas transport of altitude native soccer players near sea-level and sea-level native soccer players at altitude (ISA3600)

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.
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.
Wellness, fatigue and physical performance acclimatisation to a 2-week soccer camp at 3600 m (ISA3600)
(BMJ, 2013) Martin Buchheit; Ben Simpson; Laura A. Garvican‐Lewis; Kristal Hammond; Marlen Kley; Walter Schmidt; Robert J. Aughey; Rudy Soria; Charli Sargent; Gregory D. Roach
Despite partial physiological and perceptual acclimatisation, 2 weeks is insufficient for restoration of physical performance in young sea-level native soccer players. Because of the possible decrement in 20 m sprint time, a greater emphasis on speed training may be required during and after altitude training. The specific time course of restoration for each variable suggests that they measure different aspects of acclimatisation to 3600 m; they should therefore be used in combination to assess adaptation to altitude.
