    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.

    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.

    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.
