The Diamonds monthly P/AR competition Vianney Koelman Dutch Eindhoven Rowing Association Beatrix and The Diamonds (Over Sixties Erging Group) Cyclists are used to a power-to-weight performance metric measured in Watts per kilogram. The power-to-age-reserve ratio (abbreviated as P/AR and measured in Watts per year) provides us with a somewhat similar metric. The objective of this novel metric is to create a level playing field across sexes and ages for ergometer events such as RowErg and BikeErg competitions. So what is 'age-reserve'? We are all aware that once we enter our thirties, the power our bodies are capable of generating will gradually drop. Every year we grow older, the odds are our power figures will be less than those from a year before. This also holds for world-class athletes. As an example, below figure shows the power delivered by male and female RowErg 2k world record holders against the athlete’s age. Straight lines fit nicely through both sets of
