Summary

This summary is machine-generated.

Overweight individuals exhibit reduced postural stability during gait initiation, particularly in the anterior-posterior direction. Managing body weight is crucial for preventing falls in this population.

Public Health

Background:

Accidental falls are a significant concern, especially during gait initiation.
Excess body weight is a known risk factor contributing to increased fall incidence.

Purpose of the Study:

To investigate gait initiation differences between overweight and normal-weight individuals.
To assess the impact of body weight on postural stability during gait initiation.

Main Methods:

Comparison of 14 overweight and 14 normal-weight young adults.
Gait initiation task performed under single-task and dual-task conditions.
Assessment of spatial-temporal and postural stability measures.

Main Results:

Overweight individuals showed compromised postural stability during gait initiation.
A decrease in margin of stability in the anterior-posterior direction was observed in overweight participants.
Cognitive task interference on gait initiation was comparable between groups.

Conclusions:

Overweight status negatively impacts postural stability during gait initiation.
Findings underscore the importance of weight management for fall prevention strategies.
Understanding these mechanisms can inform interventions for reducing fall risks in overweight populations.
