# Weight-adjusted Ergometer Times



In competitive rowing, ergometer tests are used to assess fitness of

athletes and the 2000m test is the standard. The ability to generate

power is dependent on body weight. The exact relation between body

weight and power depends on more factors and the relation to boat speed

is even more complicated: see [Physics of Rowing]. However, the formula

made popular by [C2] is generally accepted as a measure of fitness.



Below is a graph where lines connect points of equal fitness. It is

generated by the R code in this repository.

# Ergonometer Splits



The table below estimates 500m split times for popular distances and

intensity levels. The table shows both absolute 500m splits and splits

relative to the split for a 30 minute at rate 20 ("30R20") workout.

These splits should be considered just a starting point. The estimation

might not be correct and individual physiology varies - some people are

better sprinters than endurance athletes and vice versa. Especially on

the fast end athletes will know their times and splits and would not

have to rely on this table.
