Key result
Fat-free mass explains ~58% of variability in rowing performance, further enhanced by leg extension power.
Cross-Sectional (n=332)
Fat-free mass and bilateral leg extension power are significant predictors of 2000 m rowing ergometer performance in young oarsmen.
Fat-free mass and leg power may aid rowing athlete monitoring; hypothesis-generating for training targets, requiring prospective validation.
We evaluated the impact of bilateral leg extension power and fat-free mass on 2000 m rowing ergometer performance in 332 young oarsmen (age 21+/-2 years, height 1.76+/-0.05 m, body mass 62+/-6 kg; mean+/-s). The 2000 m rowing performance time was correlated with height (1.62-1.93 m; R2=0.23, P<0.001), body mass (53-95 kg; R2=0.53, P<0.001), fat-free mass (47-82 kg; R2=0.58, P<0.001) and bilateral leg extension power (1202-3302 W; R2=0.38, P<0.001). Multiple regression analysis selected fat-free mass and bilateral leg extension power as regressor variables. Fat-free mass explained 58% of the variability in rowing performance and the inclusion of bilateral leg extension power improved the power of prediction by 5%. The results suggest that rowing involves almost every muscle in the body and that bilateral leg extension power is very important during this activity.

Yoshiga et al. (2003) conducted a cross-sectional in Healthy young oarsmen (n=332). Fat-free mass and bilateral leg extension power was evaluated on 2000 m rowing ergometer performance time (R2=0.58, p=<0.001). Fat-free mass explained 58% of the variability in 2000 m rowing performance (P<0.001), and adding bilateral leg extension power improved prediction by 5%.
