Back Muscle Fatigue Might Lead To Alternated Spine Loading In Recreational Ergometer Rowing, Till Koopmann, Stephan Dill, Gert-Peter Brüggemann, Steffen Willwacher

ISBS Proceedings Archive

The purpose of this study was to investigate fatigue related changes in spinal kinematics and muscle activity of back muscles during a 2000 m all-out performance on a rowing ergometer. Kinematic data of the trunk and EMG data of eight back muscles were recorded for ten subjects. A novel approach analyzing the spinal curvature was utilized identifying a significant increase (p < 0.05) for the thoracic spine. For the M. trapezius a significantly decreased mean frequency (p < 0.05) was found. The lumbar spine and the M. erector spinae showed no significant changes (p > 0.05). These results contrast with findings for elite rowers which might be explained by a different rowing technique. Increased spinal curvature is a factor for injury risk. Thus, rowing programs should include monitoring of spinal curvature and strengthening of …
