DRAG FACTOR ON ROWING ERGOMETER DURING 2000-M PERFORMANCE IN YOUNG ROWERS

Abstract (English)

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<0.001) correlated to body weight (T110 : r=0.79; T130 : r=0.86; and T150 : r=0.84), and height (T110: r=0.78; T130: r=0.83; T150: r=0.85).
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.
