Experimental Analysis of the Distribution of Traction Coefficient in the Shoe-Ground Contact Area during Running

Relationship between shoe grip properties and distributions of traction coefficient, which is obtained from horizontal ground reaction force (GRF) divided by normal GRF, were experimentally investigated during running. The experiments were conducted with sensor shoes mounted miniature triaxial force...
