The 500m row is a test of maximal anaerobic capacity.
The test requires you to row maximally until a distance of 500m is reached.
Typically this test should take you <2 minutes to complete with shorter times indicating better fitness, fatigue resistance, and anaerobic capacity.
Scoring well in these areas is important for field athletes, runners, and the general population alike as it correlates well to increased performance and measures of health.
