So, going through this whole process with my daughter, we are at a D1 unofficial visit right now, and we talked with the coaches about ERGs, etc. Of course the 2K ERG is a key determinant for scholarship eligibility in rowing, but we also talked about how coaches take total power into account. So how do you test?
This test can be done by your coaches, and is a 10 second test where you row as hard and as fast as you can. The resistance is set to high (200 on the CII), and max wattage is recorded. Top performing high school men should be in the 6.5-8 range, and women in the 4.5-7.5 range. I found a great overview article here:
When rowing, speed is not everything, and power is very important. Typically, larger, heavier rowers have the capability of producing more power. On the water, a heavier person contributes to a boat that sits deeper in the water, which creates more drag. Drag is a resistant force that the other rowers in the boat need to overcome. The ERG has no way of adjusting for this weight difference, and a larger rower can seem to have more potential than their lighter peers. So when evaluating ERG times, coaches will create a weight adjusted score, using a specific calculation. Here is a link to the Concept II Weight Adjusted ERG Calculator.
So the real question is "How does the weight-adjusted ERG come into play in Rowing Scholarships?"
Coaches will evaluate the weight-to-power ratio for their recruits. So for women, typically D1 coaches will look for weight adjusted scores below 7:00.
