Custom foot orthoses improve performance, but do not modify the biomechanical manifestation of fatigue, during repeated treadmill sprints
<h3>Purpose</h3><p dir="ltr">We determined the effect of custom foot orthotics manufactured from ethyl-vinyl acetate (EVA) and expanded thermoplastic polyurethane (TPU) materials, both compared to a control condition (CON; shoes only) during repeated sprints on running me...

| description | <h3>Purpose</h3><p dir="ltr">We determined the effect of custom foot orthotics manufactured from ethyl-vinyl acetate (EVA) and expanded thermoplastic polyurethane (TPU) materials, both compared to a control condition (CON; shoes only) during repeated sprints on running mechanical alterations.</p><h3>Methods</h3><p dir="ltr">Eighteen males performed eight, 5-s sprints with 25-s recovery on an instrumented sprint treadmill in three footwear conditions (EVA, TPU and CON). Mechanical data consisted of continuous (step-by-step) measurement of running kinetics and kinematics, which were averaged for each sprint for further analysis.</p><h3>Results</h3><p dir="ltr">Distance ran in 5 s decreased from first to last sprint (<i>P</i> < 0.001), yet with higher sprints 1–8 values for both EVA (<i>P</i> = 0.004) and TPU (<i>P</i> = 0.018) versus CON. Regardless of footwear condition, mean horizontal forces, step frequency, vertical and leg stiffness decreased from sprint 1 to sprint 8 (all <i>P</i> < 0.001). Duration of the propulsive phase was globally shorter for both EVA (<i>P</i> = 0.002) and TPU (<i>P</i> = 0.021) versus CON, while braking phase duration was similar (<i>P</i> = 0.919). In the horizontal direction, peak propulsive (<i>P</i> < 0.001), but not braking (<i>P</i> = 0.172), forces also decreased from sprint 1 to sprint 8, independently of conditions.</p><h3>Conclusion</h3><p dir="ltr">Compared to shoe only, wearing EVA or TPU custom foot orthotics improved repeated treadmill sprint ability, yet provided similar fatigue-induced changes in mechanical outcomes.</p><h2>Other Information</h2><p dir="ltr">Published in: European Journal of Applied Physiology<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="http://dx.doi.org/10.1007/s00421-020-04427-0" target="_blank">http://dx.doi.org/10.1007/s00421-020-04427-0</a></p> |
