Abstract

The importance of aerobic fitness in rowing has been widely studied, and it is accepted that aerobic fitness is a key factor in rowing performance. In contrast, the impact of rowing efficacy, especially rowing form, on rowing performance has not yet been fully elucidated. The present study aimed to investigate this subject via the analysis of hip kinematics and the association of this variable with 2000 m ergometer rowing test performance. Eleven adult male rowers underwent a 2000 m rowing test on an ergometer and the exhaled gas was analyzed. The hip joint angle, the pelvic rotation, and the knee joint angle were measured at the catch position throughout the test. Peak VO2 was strongly associated with the time taken to complete the test (ρ=–0.96, P<0.01), thereby confirming the importance of aerobic capacity in rowing performance. The variance of the hip joint angle of each rower was associated with peak VO2, lean mass, and test time (ρ=–0.72, –0.84, and 0.66, respectively, all P<0.05). Greater knee flexion was accompanied by larger posterior rotation of the pelvis (ρ=0.74, P<0.05), and was negatively associated with hip flexion (ρ=–0.76, P<0.05). Although we cannot confirm whether the consistency of the hip joint angle actually leads to better rowing performance, our results suggest that there are associations between the consistency of the hip joint angle, aerobic capacity, lean mass, and the time taken to complete the 2000 m ergometer rowing test.
