About

During running, each contact between the foot and the ground causes an impact. Ground reaction forces (GRF) are considered as an input into the musculoskeletal system. It involves a sudden deceleration in the lower limb packages (including muscles) which generates Soft-Tissue Vibrations (STV). The body is able to attenuate Soft-Tissue Vibrations (STV) but this capability decreases with fatigue. STV could be minimize by improving shoe midsole hardness.

Full description

Only 4 studies have studied Soft-Tissue Vibrations (STV) with a distance not exceeding 10 km and without evaluating the potential influence of the shoe. Thus, the effects of shoe midsole hardness on Soft-Tissue Vibrations (STV) and neuromuscular fatigue at the end of an intense and/or long run remains unknown.

The purpose is to compare two shoes whose only midsole hardness differs during a half-marathon on Soft-Tissue Vibrations (STV), neuromuscular fatigue and running kinetics.

Maybe the shoe ensuring a better STV damping of the medial gastrocnemius muscle would reduce neuromuscular fatigue and improve comfort.
