Background: To understand the technical differences between shot putters of different ages, this study compared biomechanical parameters of the best senior and youth Italian athletes and then to world‐class athletes (WC) assessed in previous investigations. Methods: The best throws of 16 shot putters [8 Senior (SG) and 8 Youth (YG)] were recorded by video cameras during the Italian Championships’ final and considered for 3D reconstruction. The following parameters were measured: time of the different throwing phases, shot trajectory, release angle, release velocity, and the force produced in the final phase. Results: Significant differences between SG and YG were detected in second single support time (p = 0.015), support time (p = 0.007), total time (p = 0.028) and in the force produced during the final phase (p < 0.001). A lower level of force, release speed, and a shorter shot trajectory during the double support were detected in SG compared to WC. Conclusions: The present study showed that, although the technical performance of all athletes was similar, some differences exist between YG and SG. The gap between the groups may be partially explained by the difference in force produced in the final phase of the throw and by a different interpretation of the technique.

Abstract

Background: To understand the technical differences between shot putters of different ages, this study compared biomechanical parameters of the best senior and youth Italian athletes and then to world‐class athletes (WC) assessed in previous investigations. Methods: The best throws of 16 shot putters [8 Senior (SG) and 8 Youth (YG)] were recorded by video cameras during the Italian Championships’ final and considered for 3D reconstruction. The following parameters were measured: time of the different throwing phases, shot trajectory, release angle, release velocity, and the force produced in the final phase. Results: Significant differences between SG and YG were detected in second single support time (p = 0.015), support time (p = 0.007), total time (p = 0.028) and in the force produced during the final phase (p < 0.001). A lower level of force, release speed, and a shorter shot trajectory during the double support were detected in SG compared to WC. Conclusions: The present study showed that, although the technical performance of all athletes was similar, some differences exist between YG and SG. The gap between the groups may be partially explained by the difference in force produced in the final phase of the throw and by a different interpretation of the technique.
