Correlation between body mass index and postural balance

Area of Science:

• Biomechanics
• Human Physiology
• Kinesiology

Background:

• Postural balance is crucial for daily activities and injury prevention.
• Body Mass Index (BMI) is a common metric for assessing body weight relative to height.
• Understanding the relationship between BMI and balance is important for public health and sports science.

Purpose of the Study:

• To investigate the correlation between Body Mass Index (BMI) and postural balance.
• To assess how BMI affects stability during unipodal (single-leg) support.

Main Methods:

• Forty adult males participated in the study.
• Functional stability tests were conducted using the Biodex Balance System.
• Participants were assessed for postural balance under specific stability evaluation protocols.

Main Results:

• A significant positive correlation was found between BMI and postural imbalance.
• Both general and specific stability indices (anteroposterior, lateral) showed strong correlations with BMI.
• No significant differences in balance indices were observed between dominant and non-dominant sides.

Conclusions:

• Elevated BMI necessitates increased body displacements to maintain postural equilibrium.
• Higher body mass poses a challenge to maintaining stable unipodal stance.
• This suggests that weight management may be beneficial for improving postural stability.
