Optimizing Stroke Length for Rowing: Technique & Efficiency

Question
Hi Al,  Watching the various videos on the ergs, I notice that some rowers on the recovery phase reach right forward to the wheel, whereas others seem to stop a foot or so away before beginning their power stroke.
It does seem to take a little more effort to go all the way (knees hard against ab diaphragm) but then you get a longer power stroke.   Appreciate your thoughts.  Ken


Answer
Hi Ken: Interesting question.  Allow me to address the question from the context of a racing eight on the water (it's the same as an erg, anyway).  I've tried both techniques.  At full compression (chest touching legs at the catch), you can really generate a lot power during the drive through the stroke.  After all, a long stroke is more efficient than a shorter stroke.  The downside is that when the stroke rate goes up, like at the start of the race and at the final sprint, there is a possibility that you can rush up the slide  trying to maintain the long stroke and high cadence.  The result will be a forward check of the boat which will slow it down at the catch.

My thoughts are that if you are rowing at a stroke rate of 35 strokes per minute and above, shorten up the stroke.  When you settle into the body of the race or the erg piece, a long, full compression, stroke at about 30-32 may work for you.  The stroke rates I provide are hypothetical.  Adjust to your skill level and condition.
