Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Isometric fatigue

Fatiguing intermittent isometric exertions of trunk extensor muscles will be performed.

Group Type EXPERIMENTAL

isometric trunk extensor muscles fatigue

Intervention Type OTHER

Participants will perform three sets of intermittent isometric efforts between 50 and 60 percents of their maximal isometric strength. A padded force sensor will be placed approximately at the level of the 7th thoracic vertebrae. The first two sets will last six minutes each, while the third set will last three minutes. Between each set participants will rest for two minutes.
