While numerous studies have investigated the biomechanics of able-bodied rowing, few studies have been completed with para-rowing set-ups. The purpose of this research was to provide benchmark data for handle kinetics and joint kinematics for able-bodied athletes rowing in para- rowing set-ups on an indoor ergometer. Able-bodied varsity rowers performed maximal trials in three para-rowing set-ups; Legs, Trunk and Arms (LTA), Trunk and Arms (TA) and Arms and Shoulders (AS) rowing. The handle force kinetics of the LTA stroke were comparable to the values for able-bodied literature. Lumbar flexion at the catch, extension at the finish and total range of motion were, however, greater than values in the literature for able-bodied athletes in the LTA set-up. Additionally, rowers in TA and AS set-ups utilised more extreme ranges of motion for lumbar flexion, elbow flexion and shoulder abduction than the LTA set-up. This study provides the first biomechanical values of the para-rowing strokes for researchers, coaches and athletes to use while promoting the safest training programmes possible for para-rowing.
虽然众多研究调查了健全人赛艇的生物力学,但针对残疾人赛艇装置的研究却很少。本研究的目的是为健全运动员在室内测力计上使用残疾人赛艇装置划桨时的手柄动力学和关节运动学提供基准数据。健全的大学赛艇运动员在三种残疾人赛艇装置上进行了最大强度测试;腿部、躯干和手臂(LTA)、躯干和手臂(TA)以及手臂和肩部(AS)划桨。LTA划桨动作的手柄力动力学与健全人文献中的数值相当。然而,在LTA装置中,抓桨时的腰椎前屈、结束时的伸展以及总运动范围均大于健全运动员文献中的数值。此外,与LTA装置相比,TA和AS装置中的划桨者在腰椎前屈、肘部屈曲和肩部外展方面使用了更极端的运动范围。这项研究为研究人员、教练和运动员提供了残疾人赛艇划桨动作的首个生物力学数值,以便在推广尽可能安全的残疾人赛艇训练计划时使用。
