2,000m Handicapping
Although you can easily compare times on different Indoor Rowers, it's sometimes more difficult to compare times by different people. How does a time of 7:30 by a lightweight compare against a time of 6:40 by a heavyweight? Our 2,000m handicapping system allows you to adjust times to take into consideration the effects of age and weight, something which is especially useful if you're running a smaller competition and don't want to have a few competitors in each category.
Adjustment Calculator
This incorporates both the Weight Adjustment Factor found in the Training Guide as well as an Age Correction Factor. You can choose to standardise your time by weight, age or both. If you have any comments or questions about the correction tables, contact webmaster@concept2.co.uk.
Weight Adjustment Factor
The weight adjustment factor (WAF) for weight correction is:
[weight in kilogrammes/77.27]2/9.
For timed pieces, corrected time is the actual time multiplied by the WAF. For distance pieces, the corrected distance is the actual distance divided by the WAF.
| Weight | Factor | Weight | Factor | Weight | Factor | Weight | Factor |
|---|---|---|---|---|---|---|---|
| 50.0 kgs | 0.908 | 67.5 kgs | 0.971 | 82.5 kgs | 1.015 | 97.5 kgs | 1.053 |
| 52.5 kgs | 0.918 | 70.0 kgs | 0.979 | 85.0 kgs | 1.022 | 100.0 kgs | 1.059 |
| 57.5 kgs | 0.937 | 72.5 kgs | 0.987 | 87.5 kgs | 1.028 | 102.5 kgs | 1.065 |
| 60.5 kgs | 0.946 | 75.0 kgs | 0.994 | 90.0 kgs | 1.035 | 105.0 kgs | 1.071 |
| 62.5 kgs | 0.954 | 77.5 kgs | 1.001 | 92.5 kgs | 1.041 | 107.5 kgs | 1.076 |
| 65.0 kgs | 0.963 | 80.0 kgs | 1.008 | 95.0 kgs | 1.047 | 110.0 kgs | 1.082 |
Age Adjustment
Age adjustment is based on the following formulae, which have come from research done by Eddie Fletcher of Fletcher Sports Science:
For men: performance is held to decline at 0.12% per year from the ages of 26-55 and at 0.83% a year from age 56 onwards.
For women: performance is held to decline at 0.23% per year from the ages of 26-55 and at 0.74% a year from age 56 onwards.
You can download an Excel spreadsheet which has tables showing the decline in performance from ages for men and women. Base times for men range from 5:40 (340 seconds) to 10:00 (600 seconds) and for from women 6:25 (385 seconds) to 10:00 (600 seconds)
