Research on biomechanics in rowing has mostly focused on the lumbar spine. However, injuries can also affect other body segments. Thus, the aim of this pilot study was to explore any potential variations in the kinematics of the cervical spine during two different stroke rates on the rowing ergometer in young rowers.
Twelve young rowers of regional or national level were recruited for the study. The experimental protocol consisted of two separate test sessions (i.e., a sequence of 10 consecutive strokes for each test session) at different stroke rates (i.e., 20 and 30 strokes/min) on an indoor rowing ergometer. Kinematics of the cervical spine was assessed using an inertial sensor capable of measuring joint ROM (angle of flexion, angle of extension, total angle of flexion-extension).
Although there were no differences in the flexion and total flexion-extension movements between the test sessions, a significant increase in the extension movement was found at the highest stroke rate ( = 0.04, = 0.66).
Young rowers showed changes in cervical ROM according to stroke rate. The lower control of the head during the rowing stroke cycle can lead to a higher compensation resulting in an augmented effort, influencing sports performance, and increasing the risk of injury.
划船运动生物力学的研究大多集中在腰椎上。然而,受伤也可能影响到其他身体部位。因此,本初步研究的目的是探索在划船测功仪上以不同划频进行划船时,年轻运动员颈椎运动学的任何潜在变化。
本研究招募了 12 名具有地区或国家级水平的年轻划船运动员。实验方案包括在室内划船测功仪上以不同划频(即 20 次/分和 30 次/分,每个测试阶段连续进行 10 次划桨)进行两次单独的测试阶段。使用能够测量关节 ROM(屈曲角、伸展角、屈曲-伸展总角)的惯性传感器评估颈椎运动学。
尽管在测试阶段之间没有发现屈曲和总屈伸运动的差异,但在最高划频时发现伸展运动显著增加(= 0.04,= 0.66)。
年轻运动员根据划频改变了颈椎 ROM。在划桨周期中头部控制较低可能导致更高的补偿,从而增加努力,影响运动表现,并增加受伤风险。
