Plain-language summary

This study aims to evaluate on an acute session of the central and peripheral contributions of electrical stimulation on the muscle belly of the triceps surae, electrical stimulation of the tibial nerve and voluntary exercise of the triceps surae muscle, and identify responders individuals and non-responders to stimulation of the tibial nerve. Another objective of the study is to compare the effects of conventional electrical stimulation applied to the sciatic triceps muscle, tibial nerve stimulation and voluntary exercise after eight weeks of training in healthy individuals.

Inclusion Criteria: * Classified as physically active according to the INTERNATIONAL QUESTIONNAIRE OF PHYSICAL ACTIVITY, * To practice only recreational physical activity, * Achieve minimum torque of 30% of the (maximal voluntary isometric contraction during conventional NMES * Be at least 3 months without practicing strength training. Exclusion Criteria: * Present some type of skeletal muscle dysfunction that may interfere with the tests, * Present intolerance to NMES in the muscular or tibial nerve, Make use of analgesics, antidepressants, tranquillizers or other agents of central action * To present cardiovascular or peripheral vascular problems, chronic diseases, neurological or muscular affections that will undermine the complete execution of the study design by the volunteer.
