Resumo
Introduction: The javelin throwing is a peculiar discipline in which the thrower intents to transfer the greatest acceleration from the run-up to the javelin at the instant of release. Javelin throw and biomechanics have kept a strong relationship, assisting on understanding its technique and its connection with performance outcomes. The present review aims to complete a deep overview of the studies related to javelin throw’s kinematic analysis, understand how javelin’s technical information has been assessed, and highlight future perspectives on kinematic tools for javelin’s evaluation. Methods: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) principles were followed in this review. PubMEd/MEDLINE, World Wide Science and IAAF’s research database. Results: Distance: Elite male=: 81.22 ± 4.01 m; Elite female= 60.98 ± 2.35 m; Non-elite male: 50.84 ± 13.6 m; Non-elite female: 34.83 m. Release Velocity: Elite male= 28.24 ± 0.87 m/s; Elite female= 23.53 ± 1.27 m/s; Non-elite male= 18.58 ± 4.33 m/s; Non-elite female= 17.42 m/s. Release Height: Elite male= 1.94 ± 0.08 m; Elite female= 1.82 ± 0.06 m; Non-elite male= 1.99 ± 0.13 m; Non-elite female= 1.89 m. Release Angle: Elite male: 34.38 ± 2.22º; Elite female: 35.52 ± 3.28 º; Non-elite male: 36.4º; Non-elite female: 44.2º. Conclusions: The release velocity is considered the most important parameter determining the distance thrown. The studies on javelin throwing use the video recording to analyze its kinematic parameters. Several parameters do not describe a linear efficiency tendency and show that diferente throwing techniques end out to be similarly effective.
