Studies have shown that obese individuals may require more attentional resources to perform postural control compared to non-obese individuals. However, it is unclear if this difference in the allocation of attention can only be observed in body positions that lead to a higher level of instability. The objective of this study was to investigate if obesity affects the allocation of attention for maintaining body postures with different levels of balance demand. Ten obese women (BMI = 41.7 ± 8.5) and ten non-obese women (BMI = 21.8 ± 1.3) volunteers were assigned into two groups (mean age = 39.7 ± 7.6): obese and eutrophic. The visual reaction time, simultaneous with the maintenance of the body positions with different levels of balance demand (sitting, standing and unipedal stance), was used to infer the allocation of attentional resources. A longer reaction time was observed in the unipedal stance, compared to the other positions, for both groups. However, no difference was observed between obese and eutrophic

维持不同体位对肥胖和非肥胖女性注意分配的影响

研究表明，与非肥胖者相比，肥胖者可能需要更多注意力资源来进行姿势控制。但是，尚不清楚这种注意力分配的差异是否只能在导致更高程度的不稳定性的身体姿势中观察到。这项研究的目的是调查肥胖是否会影响保持平衡不同水平的身体姿势的注意力分配。将十名肥胖妇女（BMI = 41.7±8.5）和十名非肥胖妇女（BMI = 21.8±1.3）志愿者分为肥胖和富营养化两组（平均年龄= 39.7±7.6）。视觉反应时间与保持不同水平的平衡需求（坐姿，站立姿势和单足姿势）的身体姿势同时被用来推断注意力资源的分配。与其他位置相比，两组的单足姿势均观察到更长的反应时间。但是，肥胖与富营养化之间没有差异
