Low back pain (LBP) is the most prevalent injury in rowing. The high use of ergometers have been associated win increased LBP and sliding ergometers has proposed to reduce this stress. The purpose of this study was to examine the lumbar flexion angles on fixed and sliding ergometers versus on water conditions. Four elite female adult rowers volunteered for this study and completed a 1,000 meter maximal test on the stationary and fixed ergometers and then on water. Lumbar curvature (% flexion) was calculated) for the first 0.47 s following the catch position. Standardized mean differences (effect size) were calculated to examine differences in %ROM over time for each condition and between conditions. Results found that fixed rowers ergometers induced the greatest amount if lumbar flexion, with some reduction for sliding ergometers compared to on water.
