Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • The subjects of the experimental group will be recruited among experienced ultra-runners . They all have run at least a 12 hour race or longer.
  • The control group will be recruited among experienced ultra-runners . Age of control group will be age experimental group more or less 2 years.

You may not qualify if:

  • The subjects will not be selected if:
  • they were injured in the 3 months before the experiment
