| Outline of Final Research Achievements |
The purpose of this study was to investigate the relationship between the running velocity and the electromyogram for prosthetic sprinter.Prosthesis Sprinter was T44 class. Every year he is in the Japan Para Championships as an T&F athlete.The experiment was conducted twice. Surface electromyograms of both legs measured the vastus lateralis, vastus medialis, etc. Also, the tibialis anterior and gastrocnemius muscle on the healthy side were measured.The major results were as follows.
The maximum running velocity was expressed approximately 4.8 seconds after the start. The rate decrease of running velocity was 14.8%.The integrated value of the surface electromyogram of the Vastus Medialis during running was 1.4 times larger on the healthy side than on the prosthetic side.The average value of stride was 1.37 m on the prosthesis side and 1.40 m on the healthy side. The prosthetic limb side means kicking with the healthy side as the supporting leg and grounding on the prosthetic side.
