Abstract
We present two case studies that make use of wearable technology to provide performance indicators on optimal swim stroke techniques in breaststroke (case 1) and freestyle (case 2). In the first case study, we present and use a novel metric, the velocity variation score, to maximise breaststroke technical performance for an athlete with Achondroplasia Dwarfism, by comparing their normal technique to two alternates, focused on 1) fast arm sculling and 2) high stroke rate (HSR). We observed lower velocity variation scores using the adapted breaststroke techniques (p < 0.001), the HSR technique had the lowest velocity variation score (p < 0.001). In the second case, we determine the optimal breathing strategy, breathing to the impaired or unimpaired side, for an athlete with a unilateral hand impairment performing freestyle swimming. Results showed that the forward velocity was significantly lower in the left-to-right stroke cycle transition and right (arm pull) when breathing to the impaired (left) side. To varying degrees, these cases demonstrate that wearable-based intra-stroke analyses can provide individualised technique recommendations that benefit competitive race peformance.
期刊介绍:
Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic).
Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly.
Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
