Childhood obesity affects postural control and aiming performance during an upper limb movement

Area of Science:

• Pediatric motor control
• Obesity research
• Biomechanics

Background:

• Obesity is known to impair postural and movement control.
• Quantifying these effects on functional motor tasks in children is crucial.
• Previous research has not fully explored obesity's impact on aiming tasks in pediatric populations.

Purpose of the Study:

• To investigate the influence of obesity on aiming task performance in children.
• To compare motor control and postural stability between healthy-weight and obese children.
• To analyze task execution in both standing and seated positions.

Main Methods:

• Participants included 12 healthy-weight and 11 obese children (8-11 years).
• Children performed aiming tasks with varying target sizes in standing and seated postures.
• Hand movement time (MT) and center of pressure (COP) speed were measured.

Main Results:

• Obese children demonstrated significantly longer movement times (MT) in both positions.
• This increase in MT was attributed to a prolonged deceleration phase.
• Obese children exhibited greater center of pressure (COP) speed, indicating reduced postural stability.

Conclusions:

• Obesity imposes a significant postural constraint on children during aiming tasks.
• Obese children require more time to adjust movements due to increased postural instability.
• These findings highlight the complex motor challenges associated with childhood obesity.
