    摘要:

    目的 探究老年人和青年人身体活动、久坐行为和平衡能力的差异,以及不同强度身体活动水平和久坐行为与平衡能力的相关性。方法 选取74名老年人和60名青年人,采用三轴加速度计对其身体活动和久坐行为进行监测,并运用三维测力台对其静态平衡能力进行测量。结果 老年女性中高强度身体活动与静态平衡能力之间呈显著正相关关系(P<0.05),久坐时间与静态平衡能力呈显著负相关关系(P<0.05);老年男性久坐中断次数与静态平衡能力呈显著正相关关系(P<0.05)。结论 与青年人相比,老年人每日轻度身体活动水平更高,久坐时间更少。在老年人中,尤其是老年女性,拥有较高的中高强度身体活动水平者或较少久坐时间者静态平衡控制能力更好。身体活动对平衡能力控制存在一定积极作用。

    Abstract:

    Objective To explore the differences in physical activity, sedentary behaviour and balance ability between older adults and young people, and the correlation of physical activity at different levels and sedentary behaviour with balance ability. Methods A total of 74 older adults and 60 young people were selected. The physical activity and sedentary behaviour of the subjects were monitored by three-axis accelerometers, and their static balance ability was measured by three-dimensional (3D) force platform. Results For elderly women, moderate-to-vigorous physical activity (MVPA) were positively correlated with static balance ability (P<0.05), and sedentary time was negatively correlated with static balance ability (P<0.05). For elderly men, sedentary breaks were positively correlated with static balance ability (P<0.05). Conclusions Compared with young people, older adults have higher light physical activity levels and less sedentary time. For older adults, especially elderly women, those with higher MVPA levels or less sedentary time have better static balance ability. Physical activity has a positive effect on balance control.
