Abstract:
The clear hip circle backward to handstand (CHCH) is a technically demanding
gymnastic element on the uneven bars that showcase the athlete’s body
coordination and speed. Most of the players, CHCH start with a handstand on the
bar to obtain the maximum potential energy. It includes a swing backward and a
transition of under grip and over grip. The moving of shoulders and hip joints
through CHCH are key factors to perform skill artistically. This study aims to
assess the influence of the initial angle of the shoulder and hip angle near the bars
on the executions. Chinese female players (n=32, age 9+2 years, training age 4+1
years) were selected as a sample of the study. Three tests were employed for the
sample: pre-test, mid-test, and post-test. The technical corrections were introduced
during the training period to the treatment group (16) throughout one training
module in a pre-competition period: shoulder movement and hip angle were
considered to correct the movement pattern. A high-speed camera (100 Hz) and
reflective markers (14mm) were used to determine the time history of attached
markers on the joints of subjects on the sagittal plane surface. The execution of
CHCH performance of the treatment group between the pre-test and post-test
shows significant improvement p value = 0.001595 (p<0.005) by paired t- Test.
Therefore, the execution of CHCH performance will be increased when the player
uses the right body posture throughout the movement: the initial shoulder
placement (not moving forward in the first 450 of motion), and hip angles (close to
1800) are special technical corrections.
