CASE STUDIES OF ASYMMETRIES IN SWIMMING

Abstract

An interrelated influence of strength, flexibility, anthropometric and technique asymmetries affects performance in swimming. Underpinning aetiologies include both acquired and inherited factors. The combination of factors varies among swimmers and therefore demands a multi-disciplinary case study approach to identify and correct asymmetries to improve performance and reduce incidence of injuries. The purpose of this presentation is to provide examples of analyses informing individualised interventions to correct asymmetries. Interventions comprise programmes of strength, flexibility, posture, and technique refinement. Analyses included measures of strength on the Biodex, measures of strength, posture, flexibility and anthropometry based on the International Society for the Advancement of Kinesiology (ISAK) conventions, and video-based qualitative and quantitative three-dimensional analysis of technique. Sample data of a breaststroke swimmer and a backstroke swimmer are presented to illustrate the interrelationships among strength, flexibility, posture, technique and performance.
