Experienced person in cheer dancing have a high ability to control upper limbs symmetrically

Abstract

Objective: The present study aimed to investigate whether individuals experienced in cheer dancing exhibit a superior ability to symmetrically position their upper limbs compared to non-experienced individuals.

Methods: Fourteen healthy young adult females, consisting of six experienced in cheer dancing and eight without, participated in a pose reproduction task based on verbal instructions. Shoulder joint angles were measured using the motion capture system.

Results: No significant difference was observed between the mirror and non-mirror conditions in cheer dancer group (p＝1.00). However, significant differences were found between the non-mirror condition in non-dancer group and both conditions (vs. mirror p＝0.03, vs. non-mirror p＝0.04) in cheer dancer group. These results indicate that individuals experienced in cheer dancing are capable of positioning their upper limbs symmetrically with high accuracy, even in the absence of visual feedback.

Conclusion: Compared to inexperienced dancers, experienced cheer dancers were shown to be able to position the shoulder joint symmetrically with high accuracy even without visual feedback. This suggests that cheer dancers may have high ability to symmetric control of joint position.
