Influência dos calçados de futsal no desempenho / Futsal shoes influence in performance

RESUMO

The purpose of this study was to analyze biomechanical aspects of futsal shoes since they were brand new until their total wastage. Ground reaction forces were measured (1 000 Hz) using a force plat- form (Kistler, type 9287 A) with a BIOWARE system program (Kistler, type 282Al-20), and a 12-bit AD conversor. As results, we highlight the increase for the following variables vertical force first peak (17.26), loading rate 1 (56.25), vertical force second peak (3.43), vertical force increment (14.81), loading rate 2 (25), and the decrease of time to first peak of vertical force (22.5). However, the intra-subject analysis have shown that some subjecis kept satisfactory biomechanical conditions during movement tasks to overcome the shoe wastage. As conclusion, we have verified that sport shoes influence in human movement may be not more expressivo than the locomotor system itself.
