  Apnea is a sport in which ventilation is stopped in order to push your limits by staying underwater for as long as possible (static or dynamic). With ventilation cut off, the only available source of oxygen is the one present in the blood. Measuring oxygen saturation in the blood (SPO2) is therefore very important for assessing the health of divers and ensuring their safety (1). Freedivers SPO2 can drop to 50% before risking their lives (2, 3). Because of the extreme difficulty of taking (…)

  The purpose of this study is to adapt the equipment of a
  professional DownWind (DW) Stand-Up Paddle (SUP) Foil
  Athlete Erwan JAUFFROY who had a creasy challenge in
  mind: Crossing –thanks to a hydrofoil (sort of small airplane)
  under is board- the 250 km distance between TOULON and
  CORSICA Island (Figure 1-a). But without any engine or sail
  (The FOIL CROSSING CHALLENGE). The goal is to
  minimise energy consumption, with an emphasis on his lower
  limb muscles.
