Brief Summary

Local vibration is a non-invasive neuromuscular stimulation modality used in training and rehabilitation for its effects on neuromuscular function, particularly its ability to induce nervous adaptations. Its passive application is particularly useful in cases of motor deficit or immobilization.

Several studies, including our own, have shown that vibration protocols over several weeks can induce significant gains in muscle strength, particularly in the knee extensors. However, the parameters of application remain heterogeneous, particularly with regard to the duration of the interventions.

With this in mind, a prospective controlled study is being conducted in healthy subjects, comparing four modalities of local vibration intervention targeting the knee extensors: an intensive vibration protocol over 5 consecutive days (1 session of 30 or 60 minutes per day) and a protocol spread over 4 weeks at a rate of 3 weekly sessions of 30 or 60 minutes). The objective is to evaluate and compare their immediate and delayed effects on force production and corticospinal properties. The results of this study will thus help optimize recommendations regarding the use of local vibration in muscle strengthening and neuromuscular reconditioning strategies.

Study Groups

Group "5 days and 30 min"

Participants will follow a protocol involving local vibration applied to the quadriceps muscle for 5 consecutive days, at a rate of one 30-minute session per day.

Group Type: EXPERIMENTAL

Local vibration protocol

Intervention Type: DEVICE

The vibrations will be delivered using the Vibramoov Physio device, positioned directly on the quadriceps muscle. The participant will be seated comfortably and will remain at rest throughout the session. The vibration settings will be set to an amplitude of 1 mm and a frequency of 100 Hz.

Group "5 days and 60 min"

Participants will follow a protocol involving local vibration applied to the quadriceps muscle for 5 consecutive days, at a rate of one 60-minute session per day.

Group Type: EXPERIMENTAL

Local vibration protocol

Intervention Type: DEVICE

The vibrations will be delivered using the Vibramoov Physio device, positioned directly on the quadriceps muscle. The participant will be seated comfortably and will remain at rest throughout the session. The vibration settings will be set to an amplitude of 1 mm and a frequency of 100 Hz.

Group "4-weeks and 30 min"

Participants will follow a protocol involving local vibration applied to the quadriceps muscle over a period of 4 weeks, with 3 weekly sessions of 30 minutes each, for a total of 12 sessions.
