| contents | <p>Skydiving landing mishaps have overwhelmed the sport as one of the largest causes of injury among licensed skydivers. Landing difficulties may be influenced by various kinetic and kinematic factors, which can contribute to musculoskeletal discomfort or injury development. There is a high prevalence of ankle and foot injuries among skydivers associated with skydive landings. Previous research surrounding airborne operations has focused on assessing the kinetics and kinematics of the parachute landing fall technique, parachute opening shock, and the simulated parachute half-squat. However, there is limited research regarding the kinetics of routine skydive landings. The purpose of this study is to measure the ground reaction forces during stand up skydive landings and compare them to the forces during a task commonly used to mimic a skydive landing, the drop landing. The kinetics of skydiving stand up landings have never been previously studied. Four skydive, 40 cm box landings, and 80 cm box landings were compared. It was found that vertical force was not significantly higher during landings from the 80 cm box compared to the 40 cm box. There were no statistically significant differences in vertical force between skydive landings and the 40 cm and 80 cm box drop landings. Shear forces were significantly greater during skydive landings compared to the 40 cm box drop landing (<i>p</i> ≤ 0.05). Also, 80 cm box landings had significantly more shear forces as compared to 40 cm box landings (<i>p</i> < 0.01). These results underscore the critical role of shear forces in injury risk, highlighting the need for further research to inform safety measures and injury prevention strategies within the realm of skydiving and aerial sports.</p> |
