To determine the mechanical of rowing, oxygen uptake and mechanical work rate were measured during rowing a single scull under windless conditions. Steady‐state pulmonary oxygen uptake was determined as a function of boat velocity ( v (m‐s −1 )) in 5 subjects. Oxygen uptake (1‐min −1 ) increased as 0.065 v 2.99 . Workrate in two subjects was determined as a function of v by measuring the force applied to the oar and its angular velocity. Work rate (w) was expressed as 3.85 v 3.25 . From these equations, mechanical efficiency (%) was expressed as 17 v 0.262 . Thus, mechanical efficiency increased from 20% at 2 m‐s −1 to 24% at a boat velocity of 4 m‐s −1 .
