An interventional study of Resistance training in Healthy Volunteers, Resistance Training Adaptation and Neuromuscular Adaptations, sponsored by Institut National de la Santé Et de la Recherche Médicale, France. Not yet recruiting. Open to participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-04.

This controlled trial aims to investigate the neural adaptations induced by a 4-week resistance training program targeting the triceps surae muscles. Specifically, the study will examine the contribution of the corticospinal and reticulospinal pathways to the nervous adaptations associated with resistance training. It will give us more information about the nervous pathways mediating adaptations following this type of training. The main question it aims to answer is: What is the contribution of the cortico- and reticulospinal tracts to the nervous adaptations following a resistance training program?
Participants will take part to a resistance training program of the triceps surae for 4 weeks. They will undergo assessments of corticospinal and reticulospinal excitability before and after the training intervention to determine changes in neural pathways
The findings will improve our understanding of the neural mechanisms underlying strength gains following resistance training.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Behavioral: Resistance training
Participants will complete a 4-week resistance training program targeting the triceps sure muscles (3 sessions per week).
the change in maximum force achieved during a maximal voluntary contraction (MVC) of plantar flexion (the primary action of the triceps surae muscles).
The maximum force, achieved during a maximal voluntary contraction (MVC), will be recorded using an isokinetic ergometer (Biodex Medical Systems Inc., Shirley, NY, USA).
Time frame: At baseline (before the first exercise session) and immediately after completion of the exercise sessions
The changes in the amplitude of electrophysiological responses evoked by magnetic or electrical stimulation at different levels of the neuromuscular system (cortical, thoracic, peripheral nerve).
Electrophysiological responses will be recorded using surface electromyography (sEMG), with electromyography electrodes (Contrôle Graphique Medical, Brie-Compte-Robert, France) placed on the muscle surface of the muscles under study. The following techniques will be used to elicit these responses, whether or not they are conditioned by auditory stimulation: intense auditory stimulation at 115 dB (SSI) coupled with a visual stimulus (i.e., the illumination of a red light-emitting diode, LED); non-intense auditory stimulation at 70 dB (SS) coupled with the illumination of a red LED; the illumination of the red LED without any sound stimulation (V).
