Postural stability against full-field dynamic visual disturbance in archery players

Area of Science:

• Sports Science
• Biomechanics
• Human Motor Control

Background:

• Visual disturbances can significantly impact postural stability.
• Athletes in different disciplines may exhibit varying abilities to adapt to sensory perturbations.

Purpose of the Study:

• To investigate the effects of dynamic visual disturbance on body sway in archery players, ball game players, and untrained subjects.
• To compare the postural control strategies employed by these groups under visual stress.

Main Methods:

• Participants stood on a stabilometer platform within a moving, visually perturbed box.
• Body center sway was recorded using a stabilometer during a 60-second damped sinusoidal oscillation of the visual field.
• Standard deviation of body sway in the anterior-posterior direction was analyzed.

Main Results:

• All groups initially showed increased body sway with the onset of visual disturbance.
• Archery players exhibited a significantly faster and greater reduction in body sway compared to ball game players and untrained subjects.
• This suggests enhanced adaptation to visual perturbations in elite archers.

Conclusions:

• Archery players possess superior postural stability against dynamic visual disturbances.
• Training in archery appears to promote a shift in sensorimotor dominance from vision to proprioception for balance.
• This adaptation likely contributes to improved shooting accuracy by minimizing visual interference.
