Abstract

Measurement and information technologies for the optimization of movement technique are well established in high performance sports. While measurement technologies and biomechanical aspects of sport performance are well investigated, the underlying models for technique training do not represent the state of research in motor learning and therefore have been criticized. The aim of this study was to evaluate the effects of a biomechanic training device based on system-dynamics principles of motor learning in high-performance rowing. Eight elite rowers completed a three-week training experiment in which the intervention group had to replicate varying strength curves. All subjects in the intervention group showed significantly lower proportions of force in the final phase and all but one showed higher proportions in the initial phase of the stroke, while the control group showed an opposite trend. The SPM analysis also revealed that changes occurred primarily at the beginning and end of the force progression. Observed changes in the intervention group in particular were rated positively by coaches and experts. Feedback training with varying target curves therefore appears to be a promising alternative to coach-led technical training in rowing.
