Sedentary office work poses risks to physical and cognitive health. This study investigated the effects of a 6-month yoga intervention on sedentary office workers' cognitive function and vascular parameters.
Twenty-four office workers (mean age 26.5 ± 2.9 years) with low physical activity levels participated in a 6-month yoga intervention. Vascular function (carotid and superficial femoral artery) was evaluated by Doppler ultrasound at baseline (0 and 3 months) and postintervention (corresponding to the study's 6 and 9 month time points). Correlations between cognitive and vascular measures were analyzed.
Significant associations between vascular functions and cognitive performance emerged during the yoga intervention period (3-9 months). Positive correlations were observed between carotid artery parameters and cognitive task performance in the third month after intervention (corresponding to the study's 6-month time points). Flanker task accuracy correlated with carotid artery diameter (rho = 0.454, < 0.05), while N-Back test accuracy correlated with carotid artery velocity (rho = 0.420, < 0.05). However, increased superficial femoral artery function was negatively associated with cognitive performance.
This study reveals a dynamic relationship between cognitive performance and arterial parameters during prolonged sitting, with yoga intervention potentially influencing both vascular and cognitive functions favorably. The findings suggest that yoga may effectively mitigate the negative impacts of sedentary behavior in office workers. However, further research is needed to understand the long-term effects and mechanisms involved fully.
久坐的办公室工作对身体和认知健康构成风险。本研究调查了为期6个月的瑜伽干预对久坐办公室工作人员认知功能和血管参数的影响。
24名身体活动水平较低的办公室工作人员（平均年龄26.5±2.9岁）参与了为期6个月的瑜伽干预。在基线（0个月和3个月）和干预后（对应于研究的6个月和9个月时间点）通过多普勒超声评估血管功能（颈动脉和股浅动脉）。分析了认知与血管测量之间的相关性。
在瑜伽干预期（3 - 9个月）期间，血管功能与认知表现之间出现了显著关联。在干预后的第三个月（对应于研究的6个月时间点），观察到颈动脉参数与认知任务表现之间存在正相关。侧翼任务准确性与颈动脉直径相关（rho = 0.454，P < 0.05），而N - 回溯测试准确性与颈动脉速度相关（rho = 0.420，P < 0.05）。然而，股浅动脉功能增强与认知表现呈负相关。
本研究揭示了长时间坐着期间认知表现与动脉参数之间的动态关系，瑜伽干预可能对血管和认知功能产生有利影响。研究结果表明，瑜伽可能有效减轻办公室工作人员久坐行为的负面影响。然而，需要进一步研究以充分了解其长期影响和涉及的机制。
