The variability of lower extremity mechanics in gymnastic landings on different mat materials

This investigation was conducted to investigate the influence different gymnastic mat materials have on the kinetic, kinematic and variability of the lower extremity mechanics during gymnastic landing movement. Three injury-free female gymnasts who had familiarity with the dismount were asked to perform ten backward tucked somersault dismounts off the beam onto three different mats (hard, medium and soft). Kinetic and kinematic data were recorded during each performance. Overall, participants landing on the soft mat experienced decreased vertical ground reaction forces. They also experienced decreased amount of flexion at the ankle and increased flexion at the hip when landing on the softer mats. The variability was high overall across all the mats, except force variables for the soft mat and the minimum angles variability for the hard mat. Therefore it was concluded that variability was highest within the medium mat and the kinetic and kinematic variables were in the safest parameters within the softest mat which could lead to a decrease in the overuse injury potential.
