IS JUMPING AND LANDING TECHNIQUE SYMMETRICAL IN FEMALE GYMNASTS?

Abstract

The effect of eccentric load (drop height) on lower extremity neuromuscular function and performance was examined in young healthy female gymnasts. Each gymnast (level 4 – 6, n = 15) performed five drop landings and five rebound jumps whilst barefoot from three heights (30, 60, 90 cm) onto two AMTI force platforms (1000 Hz) covered with 6 cm thick carpeted gymnastics mats. Force-time measurements were exported into custom-written software to obtain key measures such as peak force (BW), loading rate (BW/s), and takeoff power (Watts/kg). Significant asymmetry was identified in the jumping and landing performance of the gymnasts, however the level of asymmetry observed was not influenced by eccentric load. In conclusion, coaches should aim to achieve safer landing strategies by developing ambidextrous movement in young gymnasts.
