Prolonged sitting, common in many workplaces, reduces blood flow to the lower limb and has negative health outcomes. CoreChair is an active-sitting chair that encourages increased movement to help mitigate these outcomes. Physiological and cognitive measures were recorded in ten subjects over 4 h of sitting in both the CoreChair and a traditional office chair. Sitting in both chairs led to increases in calf circumference (p < 0.0001), reduced tactile sensitivity (p = 0.02), and a cognitive decline in attention (p = 0.035) over time. However, the increase in calf circumference was smaller in the CoreChair at the second (p = 0.017) and third hour (p = 0.012) compared to the traditional chair. Additionally, for the attention task, the traditional chair generated more attention-task errors (p = 0.005), while no changes were observed with the CoreChair (p = 0.13). These findings suggest that during prolonged sitting CoreChair may have modest physiological and cognitive benefits compared to a traditional chair.
长时间坐着在许多工作场所很常见，会减少下肢的血流量，并对健康产生负面影响。CoreChair 是一种主动式座椅，它鼓励增加运动，以帮助减轻这些后果。在 4 小时的坐姿中，对 10 名受试者进行了生理和认知测量，分别坐在 CoreChair 和传统办公椅上。在这两把椅子上，随着时间的推移，小腿周长会增加（p<0.0001），触觉敏感性降低（p=0.02），注意力认知能力下降（p=0.035）。然而，与传统椅子相比，CoreChair 在第二小时（p=0.017）和第三小时（p=0.012）时小腿周长的增加幅度较小。此外，对于注意力任务，传统椅子会产生更多的注意力任务错误（p=0.005），而 CoreChair 则没有观察到变化（p=0.13）。这些发现表明，在长时间坐着的情况下，与传统椅子相比，CoreChair 可能会对生理和认知产生适度的益处。
