Biomechanical exploration of the sprint of soccer players of a colombian professional team: an initial proposal

Abstract

Introduction: Football Soccer is the most popular team sport around the world, it is estimated that around 4% of the world's population practices it (1), this activity involves running, kicking, jumping, stopping and making changes of direction in high speed or half speed. The biomechanics of the sprint is important because it allows improving the technique and impact on the prevention of injuries.

Objective: To determine the biomechanical characteristics of the sprint of professional soccer team players.

Methods: descriptive observational study of a series cases of the sprint in 12 professional soccer players. We included players from 18 to 35 years old belonging to a professional team without knee, hip or ankle injuries in the last 4 weeks.

Results: The median speed was 7.44 m / s [RIQ: 6.93 - 7.75 m / s] being higher in the right leg 7.49 m / s [RIQ 6.88 - 7.74 m / s] than on the left. The median stride length was 3.21 m (RIQ 3.05-3.64 m) with predominance in the right leg 3.20 m [RIQ 3.11-3.74 m]. It was evidenced that the winger player was the one who presented the highest speed, while the middle forward was the one who presented the lowest speed of the group evaluated.

Conclusion: The biomechanical study of professional soccer players allows a characterization of the sports gesture of the sprint, allowing a different vision to those currently used both for the improvement in performance and training strategies, as well as in the possible intervention in the prevention of injuries.
