Indoor rowing is relevant for indoor training and testing. Furthermore, international indoor rowing competitions are organized using the Concept2 rowing ergometer, which permits resistance adjustments via a vent damper. To set the damper lever, indoor rowers can vary the drag factor (df) by setting the flywheel cage from 95df to 220df. To evaluate the relationship between 2000-m indoor rowing ergometer performance with different df and the body mass of young rowers. On three separate occasions organized on consecutive days, fifteen youth male rowers (age: 16.1±1.1yrs; body mass: 72.7±9.6kg; height: 177.4±6.4cm) performed maximal 2000-m rowing ergometer performances on a Concept2 (mod.D) with a 110df, 130df, and 150df, respectively. Average times (T110, T130 and T150) and stroke rate (SR110, SR130 and SR150) were measured. Pearson`s correlation was applied to examine the relationship between anthropometric characteristics of athletes and their 2000-m performances. Results: Slowest 2000-m rowing ergometer performances resulted in T110 (435.0±22.7s), intermediate in T150 (433.7±25.2s,) and fastest in T130 (419.1±24s) conditions. The highest SR emerged at 110df (SR110=35.1±0.8n.min-1), intermediate at 130df (SR130=36.7±0.7n.min-1), and lowest at 150 df (SR150= 32.7±0.7n.min-1). Rowing performances were significantly (P The fastest time and highest SR reached during 2000-m indoor rowing performances with a 130df setting could suggest coaches to favour this resistance level, independently from the anthropometric characteristics of youth athletes.
