Comments
The purpose of this study was to explore electromyography (EMG) of trunk muscles together with kinematics of the pelvis and spine of elite female rowers during the rowing stroke. Nine Rowing Canada national team candidates participated in this study performing a 2000 m race simulation. EMG activity of spinal and pelvic extensor and flexor muscles and kinematic data of the pelvis and spine were collected during the previously described period of peak force production. During this period, pelvic and spinal extensor muscles demonstrated similarities in timing of muscle activity with minimal coactivation of flexors and extensors; minimal excursion of spinal segments at this time suggests a stabilizing effect of the trunk. Minimal coactivation was noted towards late drive as trunk extension is slowed by increasing activity of the flexor muscles. This study provides baseline data of rowing kinematics and muscle recruitment strategies to assist analysis of technique and rehabilitation.
