Abstract

Objective: Fibrous adhesions impair normal muscle mechanics. The present study aimed to assess lateral gastrocnemius muscle excitation, isometric force response, and neuromuscular efficiency during explosive force in plantarflexion before and after diacutaneous fibrolysis.

Methods: Thirty-five recreational athletes were allocated in the intervention group (n = 20) treated with diacutaneous fibrolysis, while the sham group (n = 15) was treated with placebo diacutaneous fibrolysis. Force response synchronized with surface electromyography during a plantarflexion task was collected.

Results: Differences between Pre- and Post-diacutaneous fibrolysis were observed for all variables, except for the placebo group.

Conclusions: Diacutaneous fibrolysis was effective to increase force, muscle excitation, and neuromuscular efficiency on lateral gastrocnemius.
