The aim of this study is to evaluate the contractile properties of erector spinae muscles (extensor of the trunk), rectus abdominis and obliques externus (flexor of the trunk) in physically active young women, using an innovative technique such as the tensiomyography (TMG). The sample consisted of 5 young women, physically active and in a healthy condition. It was carried out a descriptive
