Cross-sectional analysis of rowing power and technique of German Junior Women in the Eight

Klaus Mattes, Nina Schaffert, Stefanie Manzer, Wolfgang Boehmert



Since ten years, the German Rowing Federation (DRV) annually conducted 2000-m-race-tests with the best-performing athletes at the beginning of the immediate-pre-competition-preparation (IPCP) for the World-Rowing-Junior-Championships (WRJC). According to previous findings, differences between year-groups, correlations between anthropometric-data, rowing-power and technique development were tested to identify trends and to define a performance-strategy. Twenty test-runs of the junior-women’s-Eight (N=156) were studied using a mobile-measuring-system that records rowing-force and rowing-angle. Body height, body mass, average handle-power with its components handle-force, velocity and handle-displacement per stroke and further rowing-technical characteristics of the rowing-stroke-length were considered and WRJC-race-times used as external-criteria. Single-factor-variance-analysis, linear-correlation, regression-analysis and cluster-analysis were calculated. Significant differences were found between year-groups in body height, body mass and in characteristic values for rowing-power and technique and significant correlations between body height and body mass with rowing-power. Further, six performance-groups were identified by rowing-technique-data. Significant reduction was found in crew’s WRJC-race-time, reflected in handle-power and its determinants. Cross-sectional-comparison showed significant increase in average handle-power and handle-force per rowing-stroke at higher stroke frequency. Based on the cross-sectional-data, selection and year-group influences, together with exercise-induced-effects, should be considered as causes. Results show a functioning preparation-system within the DRV for better prepared-junior-athletes to commence the IPCP.
