Vieira, Luiz H. P.; Cunha, Sérgio A.; Moraes, Renato; Barbieri, Fabio A.; Aquino, Rodrigo; Oliveira, Lucas de P.; Navarro, Martina; Bedo, Bruno L. S.; Santiago, Paulo R. P. – Research Quarterly for Exercise and Sport, 2018
Purpose: The purpose of this study was to compare the kicking performance of young soccer players in the U9 to U20 age groups. Method: Three hundred and sixty-six Brazilian players were evaluated on an official pitch using three-dimensional kinematics to measure (300 Hz) ball velocity (V[subscript ball]), foot velocity (V[subscript foot]),…

In this study, we analyzed the relationship between running economy (RE) and biomechanical parameters in a group running at the same relative intensity and same absolute velocity. Sixteen homogeneous male long-distance runners performed a test to determine RE at 4.4 m.s[superscript -1], corresponding to 11.1% below velocity at the ventilatory…
