Objective: The purpose of this study was to investigate if there were any general increase in

eversion angle of the heel when running in bare feet, in an exhausted condition compared to a

well rested condition, for young men without excessive pronation.

Background: Currently the majority of orthopedic workshops, sports- and running stores

supply individually designed insoles to support and/or correct biomechanical structures in the

lower extremity. A dynamic analysis will most commonly be performed of the patient on a

treadmill. Subsequently the insoles will be fabricated after the patients demand. One problem

that can occur when the running analysis is performed is that the patient is in a physically well

rested condition. When the patient gets exhausted over time, the running technique is

impaired and the strain on the lower extremity increases.

Participants: Eight male subjects.

Method: The eversion angle was compared before and after an exhausting running procedure

on the treadmill.

Result: The eversion angle tends to increase in relation to exhaustion, however not significant

(p>0.05).

Conclusion: No significant difference in eversion angle was noted in this study, however the

eversion angle tends to increase in relation to exhaustion. Serious clinicians within the field

should take this parameter into consideration to be able to make a professional assessment.
