INFLUENCE OF A SUSPENDED AID ON THE HIP MOMENT PROFILES DURING CIRCLES ON POMMEL HORSE

Because a suspended aid – a usual training aid for practicing circles on pommel horse – applies forces at the distal part of the legs, we hypothesized that it has a large influence on the hip moment profiles during circles. This study was conducted to test the hypothesis. Eighteen gymnasts performed three sets of 10 circles with and without a suspended aid, and 3-D coordinates were acquired using a Qualisys motion capture system. The force applied from the aid was determined based on the cable tension measured with a load transducer. Hip joint moments were computed with the assumption that the total leg was a single rigid body. The results confirmed that the aid altered the hip flexion-extension and lateral flexion-extension moments. Understanding such an influence will be important whenever a suspended aid is used for training.Downloads
