Spine and pelvis coordination variability in rowers with and without chronic low back pain during rowing

The aim of this study was to compare the spine-pelvis coordination and variability (CV) during rowing in elite rowers with without chronic low back pain (CLBP). Fourteen professional (6 healthy 8 CLBP) participated study. 3D kinematic upper trunk (UT), lower (LT), (LB), pelvis segments ergometer at 70% 100% peak power were captured. adjacent segments’ CV calculated using modified vector coding method. results showed that range motion increased both groups increasing intensity, especially CLBP rowers. significantly lower: LT dominancy LT/LB intensities; anti-phase pattern LB/Pelvis intensity; UT/LT early recovery, higher final recovery catch position (p < 0.05). Moreover, UT for sagittal plane; frontal plane, transverse plane preparation phase, a acceleration phase versus intensity. In conclusion cannot adapt their its increase movement chain from stops spine-pelvic junction. These findings have practical implications designing coaching rehabilitation strategies facilitate performance prevent injuries.
