Impact Differences among the Landing Phases of a Drop Vertical Jump in Soccer Players
Journal Title: Sport Mont - Year 2018, Vol 16, Issue 2
Abstract
The aim of this study was to examine the diff erences of landing phase biomechanics between the players who had anterior cruciate ligament (ACL) reconstruction and healthy participants during single leg drop vertical jump. In this study, 11 soccer players who had anterior cruciate ligament reconstruction (aged 23.0±3.6 years, height 177±5.0 cm, weight 83.8±11.7 kg) and 9 healthy soccer players( aged 22.2±2.4 years, height 178±3.0 cm, weight 74.3±6.1 kg) participated voluntarily. During the data collection phase three high speed cameras synchronized to each other and force plate were used. Visual analysis programme and MATLAB were used to calculate kinetic and kinematic variables. Landing techniques of the subjects’ were examined by fl exion angle of knee, ground reaction force and moment parameters. The statistical analyses of the measured results were performed by t-test and Pearson Correlation analysis. According to the results, it was determined that peak vertical ground reaction force exhibited significant phase diff erences (p=0.00, and p=0.00, respectively) between the groups. Obtained results can be explained with “quadriceps avoidance” motion pattern which is characterized by decreased quadriceps activity and lower external knee fl exion moment in an eff ort to control anterior translation of the tibia in subjects with ACL reconstruction. A better understanding of the diff erent phases during single-leg landings can shed a light on mechanism of non-contact anterior crucaite ligament injuries therefore future researches should assess how phase diff erences aff ect drop vertical jump performance.
