Outcome Measures

Primary Outcomes (3)

  • Changes in Operative performance

    Flight times to complete tasks in the flight simulator and report from the flight simulator controler

    measured at 12 weeks (versus baseline values)

  • Changes in Stress and HRV

    Heart rate variability measured with Polar H10 portable device

    measured at 12 weeks (versus baseline values)

  • Changes in Vestibular system control responses

    Postural control responses through CoP displacement measured with a portable force platform Biosignals Plux with data sampled at 1000 Hz and electrode impedance below 5 kΩ. Preprocessing performed using the EEGLAB toolbox, which is available for use in MATLAB (The MathWorks Inc., Natick, MA). Data downsampled to 100 Hz.

    measured at 12 weeks (versus baseline values)

Secondary Outcomes (5)

  • Changes in Body composition

    measured at 12 weeks (versus baseline values)

  • Changes in Lung capacity

    measured at 12 weeks (versus baseline values)

  • Five Facet Mindfulness Questionnaire - Changes in cognitive habilities

    measured at 12 weeks (versus baseline values)

  • Multidimensional Assessment of Interoceptive Awareness Questionnaire - Changes in cognitive habilities

    measured at 12 weeks (versus baseline values)

  • Aviation Safety Attitude Scale - Changes in cognitive habilities

    measured at 12 weeks (versus baseline values)
