dc.description.abstractThe study aimed to investigate asymmetries in lower limb kinematics and kinetics from two separate heights. Symmetry is generally referred to as one limbs exact replication of the others movement. Extensive research into biomechanical asymmetry can deliver a beneficial understanding of performance, injury and methods of data collection. Eight recreational athletes (four male and four female) (mean ±SD age - 20.5 ±0.71; Height - 177.2 ±7.51 cm; Mass - 73.09 ±12.05 kg), agreed to complete five drop landings from two heights based at 60 cm and 90 cm. Kinematic three-dimensional position data and Kinetic force plate data were collected. A single subject design was used followed by parametric statistics in the form of paired t-test to inform significant differences (p<0.05) between left and right sides. Significant asymmetry was found within 55 of 80 (68.75%) kinetic variables. However joint angle SYM data presented 60.71% of the significant asymmetries have greater flexion on the left side. Furthermore the range of magnitudes (0.44 – 2.39%) were similar to the values reported during touchdown for gymnastics movements (0.87 – 3.30%; Exell et al., 2012c). Kinetic variables at the instance of touchdown; males show greater values on the right hand side for 100% of the variables compared to females who have no clear pattern. The main findings showed key kinematic and kinetic asymmetry during the landing varied on an individual basis with no overall key patterns or trends between genders. The high occurrence of asymmetry in the ankle joint at touchdown could potential expose athletes to increased injury potential in one limb over the other. Findings from this study will provide information for technical coaching in skills which are thought to have absolute symmetry. Furthermore kinetic asymmetry and discrete variables at the instance of touchdown will highlight potential injury possibilities. The research outcome could have implications for data collection and clinicians, biomechanics and coaches regarding potential injury.en_US
