Thanks HL - 100% right. And putting slides under a C11 does not make a
Rowperfect - just as bolting wings to a Ferrari doesn't make a Lear
Jet. If you want to fly, properly and safely, you choose the aeroplane
which was designed from the ground up! By the way, has anyone seen the
article below from Sports Biomechanics? Regards, Mark

> The RowPerfect Ergometer: A Training Aid for On-Water Single Scull Rowing
> Bruce Elliott, Andrew Lyttle, and Olivia Burkett
> The purpose of this study was to compare rowing technique on the dynamic
RowPerfect ergometer with a single scull. Eight national-level rowers
performed on both the RowPerfect ergometer and in a single scull over
at rates of 24, 26 and 28 strokes/minute. Blade force and oar angle
(on-water) and handle force and stroke length (on the ergometer) were
measured. Both force and stroke angle/length were normalised from 0 to
(where 100 was the peak value.) Body positions of the subjects at both
catch and finish of each of these rowing strokes were also compared
stroke rate. The coefficient of multiple determination (CMD) was used
measure the consistencey of force curves over a sample of five
storkes for each rower. Cross-correlations were performed between the
and right-side on-water sculling force curves and a mean of these
with the ergometer curve for each rowere. Stroke angle/length, which
vary with rate, was similar for both forms of rowing. The CMDs showed
consistency across the normalised strokes of each subject (=0.98).
Cross-correlation values of 0.91, 0.92 and 0.93 were recorded between
force curves from the ergometer and on-water trials for stroke rates
26 and 28 strokes/minute, respectively. The mean trunk, thigh and
angles at the catch and finish of the stroke were also similar across
stroke rates as determined by t-tests. Results indicate that technique
on the RowPerfect ergometer was similar to that for on-water sculling,
validating its use in off-water training.
