Brief Summary

Objective of the study The main objectives of this project are:

  1. 1.To assess the influence of mental fatigue on a return-to-play test battery in healthy population
  2. 2.To assess the influence of mental fatigue on brain functioning during a balance and reaction time task in healthy population In a later stage, these experiments could be carried out in a clinical context (e.g. in an ankle sprain population).

Outcome Measures

Primary Outcomes (5)

  • Single-leg hop test

    Single-leg hop test for distance performance

    Change in single-leg hop test for distance performance: from baseline and 120 minutes after baseline (immediately after the flanker task)

  • Vertical jump test

    Vertical jump height performance

    Change in vertical jump height performance: from baseline and 120 minutes after baseline (immediately after the flanker task)

  • Y-balance test

    Balance and reach performance; participants have to maintain their balance while reaching as far as possible along 3 different directions.

    Change in Y-balance performance: from baseline and 120 minutes after baseline (immediately after the flanker task)

  • Balance-reaction time test

    Balance and reaction time performance; participants have to maintain their balance while reacting as fast as possible in 3 different directions.

    Change in balance and reaction time performance: from baseline and 120 minutes after baseline (immediately after the flanker task)

  • EEG power spectrum analysis

    Brain activity during the Y-balance test, balance-reaction time test and flanker task will be registered at baseline and immediately after the flanker task

    Change in EEG power spectrum: from baseline and 120 minutes after baseline (immediately after the flanker task)

Secondary Outcomes (3)

  • Mental fatigue Visual Analogue Scale (M-VAS)

    Change in M-VAS: at baseline, 20 min after baseline (immediately after the first test battery), 120 min after baseline (immediately after the second flanker task) and 135 min after baseline (immediately after the final test battery)

  • Flanker task

    Change in flanker task: at baseline and 90 minutes after baseline (immediately after the mental fatiguing task)

  • 90-minute stroop task

    Change in reaction time and accuracy will be assessed with a 90-min cognitive task; Reaction Time and Accuracy during the 90-min task will be reported as mean reaction time and accuracy during 8 blocks of 11min15sec
