Head acceleration in blind football players: A laboratory-based exploratory study

Area of Science:

• Biomechanics
• Sports Medicine
• Neurology

Background:

• Head acceleration is a key factor in sports-related concussions.
• Understanding head kinematics in adaptive sports like blind football is crucial for injury prevention.

Purpose of the Study:

• To compare head acceleration between blind and non-disabled football players.
• To investigate the effect of anticipated versus unanticipated conditions on head acceleration in blind football players.

Main Methods:

• A laboratory-based study involving ten football players (five blind, five non-disabled).
• Standardized head perturbations (flexion, extension, lateral flexion, rotation) were applied using a custom apparatus.
• Peak linear and angular head accelerations were measured under anticipated and unanticipated conditions.

Main Results:

• No statistically significant differences in head acceleration were found between groups.
• A descriptive pattern showed higher peak angular acceleration in blind football players during rotational perturbations.
• Blind football players exhibited higher head accelerations under unanticipated conditions compared to anticipated ones, particularly in lateral flexion.

Conclusions:

• Blind football players descriptively experienced higher peak angular acceleration during rotational movements.
• Head accelerations were consistently higher in unanticipated versus anticipated conditions for blind football players.
• Further research with larger sample sizes is needed to confirm these trends and inform concussion prevention strategies in blind football.
