Data were extracted from footage of the competition to calculate kinematic variables along with jumper position. Through cluster analysis, six types of throw were identified according to distance and velocity: short-fast, short-slow, medium short-fast, medium short-slow, medium long and long. Significant differences were detected in all the variables examined depending on the throw category (throw distance P<0.001; Partial eta square η2=0.932, height P=0.032; η2=0.096, flight time P<0.001; η2=0.789, starting angle P<0.001; η2=0.502, initial velocity P<0.001; η2=0.767 and jumper position P<0.001; η2=0.641). In the discriminant analysis, all variables except jumper position were able to correctly classify 100% of the throws. In addi- tion, we differentiated the six participating teams, finding significant differences in throw height (Scotland vs England difference means d=0.32m, Ireland d=0.36m or France d=0.37m), flight time (Italy vs England d=0.34s or Ireland d=0.33s) and angle (Italy vs England d=9.72º or Ireland d=8.49º and Scotland vs England d=8.27º or Ireland d=7.04º). Our findings have implications for training and team analysis (own and rival) and also provide direction for future investigations. 2018 artículo científico 1885-3137 https://www.redalyc.org/articulo.oa?id=71055532004 https://www.redalyc.org/journal/710/71055532004/ https://www.redalyc.org/journal/710/71055532004/html/ https://www.redalyc.org/journal/710/71055532004/71055532004.epub https://www.redalyc.org/journal/710/71055532004/movil https://doi.org/10.5232/ricyde2018.05203 en http://www.redalyc.org/revista.oa?id=710 RICYDE.
