| Abstract: | 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; R 2?=?0.23, P?<0.001), body mass (53–95?kg; R 2?=?0.53, P?<0.001), fat-free mass (47–82?kg; R 2?=?0.58, P?<0.001) and bilateral leg extension power (1202–3302?W; R 2?=?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. |
