The aim of this study was to examine the influence of dual-task
constraints on movement and force control in children who are overweight and
obese. DESIGN: Twelve children who are overweight and obese (4-12 yrs old) and 12
age-matched children with normal weight participated. The children walked along a
path at a self-selected pace under two conditions: walking carrying nothing
(baseline condition) and walking while carrying a box (dual-task condition).
RESULTS: The overweight/obese group showed less normalized hand vertical motion
and shoulder range of motion compared with the control group (all P's < 0.05).
However, in comparison with the baseline condition, the overweight/obese group
decreased gait velocity and stride length and increased step width, lateral hand
movement, lateral spine movement, and medial/lateral ground reaction force during
the dual-task condition (all P's < 0.05). CONCLUSIONS: These findings indicate
that children who are overweight and obese modify lateral movements and force
organization when faced with dual-task constraints, which may influence their
ability to maintain safety when dual tasking is required.
