Abstract/OtherAbstract:
In sport setting, imagery is regarded as one of the most popular and effective techniques to enhance the learning strategies and performance of skills. However, its effect on correction of improper technique such as landing which causes injury is not clear. Therefore, the purpose of this study is to investigate the effect of imagery on knee and hip flexion angle during jump-landing in females. The landing motions were captured from forty female physical education students (height: 166.05, ± 7.52 cm; mass: 55.75 ± 9.23 kg; age: 20.45, ± 1.66 years) using a three-dimensional technique at 60 Hz by three video cameras. There was significant difference between no imagery (27.04±2.40 deg) and imagery (22.98±1.95 deg) on knee valgus angle and also there was significant difference between no imagery (44.88±13.46 deg) and imagery (62.35±8.34 deg) on knee flexion angle (p≤0.001). There is, in addition, significant difference between effect of no imagery (28.60 ± 4.88 deg) and imagery (39.73 ± 7.29 deg) on hip flexion angle with (p≤0.001). It seems that imagery can be utilized to correct motions and movements. Based on this finding, we concluded that imagery, probably, can be used as a training strategy to change athletic motion, however, the authors suggest further investigation into the efficacy of imagery in the prevention of ACL injury.
