COMPARISON OF FORCE CURVES BETWEEN ON-WATER SINGLE SCULL ROWING AND THE ROWPERFECT ERGOMETER

Abstract

The purpose of this study was to compare the RowPerfect ergometer to single scull rowing in order to validate its use in rowing training and crew selection. Eight national-level rowers were tested over three sets of 500 m, at stroke rates of 24, 26 and 28, on both the RowPerfect ergometer and on-water in a single scull. Blade force and oar angle were measured on-water while force and stroke length were measured on the ergometer. Both force and angle/length were normalised for comparison between the two forms of rowing. Co-efficient of multiple determination revealed high consistency levels for the 5 representative normalised stokes of each subject. Cross-correlation demonstrated high correlations between the force curves of the ergometer and on-water sculling. Thus, the results indicate that the RowPerfect ergometer successfully simulates on-water sculling.
