背景:久坐行为是慢性疾病和死亡率的危险因素,即使是那些经常锻炼的人。考虑到将体育活动纳入日常时间表的时间限制,以及在办公室工作期间坐着的可能性很高,这种环境可以作为减少久坐行为的干预措施的潜在可行环境.
结果:在员工健康中心进行了一项随机交叉临床试验。连续4天评估了四个办公室设置:第1天的固定或坐站(参考),和3个随后的活动工作站(站立,走路,或步进机)按随机顺序。神经认知功能(选择性注意力,语法推理,奇怪的一个出来,对象推理,视觉空间智能,有限保留内存,配对伙伴学习,和DigitSpan)和精细运动技能(打字速度和准确性)使用经过验证的工具进行测试。使用线性回归和广义估计方程来调整标准误差,在站点之间比较了平均分数。Bonferroni方法针对多重比较进行了调整。纳入健康受试者(n=44),28名(64%)女性,平均±SD年龄35±11岁,重量75.5±17.1kg,高度168.5±10.0厘米,体重指数26.5±5.2kg/m2。当比较活跃的站和坐着时,神经认知测验要么改善,要么保持不变,而打字速度下降而不影响打字错误。第一天后总体结果有所改善,表明习惯。我们观察到活动站之间没有重大差异,除了平均打字速度降低42.5和39.7个单词/分钟站立和步进(P=0.003)。
结论:主动工作站改善了认知表现,这表明这些工作站可以帮助减少久坐时间,而不会损害工作表现。

BACKGROUND: Extended sedentary behavior is a risk factor for chronic disease and mortality, even among those who exercise regularly. Given the time constraints of incorporating physical activity into daily schedules, and the high likelihood of sitting during office work, this environment may serve as a potentially feasible setting for interventions to reduce sedentary behavior.
RESULTS: A randomized cross-over clinical
trial was conducted at an employee wellness center. Four office settings were evaluated on 4 consecutive days: stationary or sitting station on day 1 (referent), and 3 subsequent active workstations (standing, walking, or stepper) in randomized order. Neurocognitive function (Selective Attention, Grammatical Reasoning, Odd One Out, Object Reasoning, Visuospatial Intelligence, Limited-Hold Memory, Paired Associates Learning, and Digit Span) and fine motor skills (
typing speed and accuracy) were tested using validated tools. Average scores were compared among stations using linear regression with generalized estimating equations to adjust standard errors. Bonferroni method adjusted for multiple comparisons. Healthy subjects were enrolled (n=44), 28 (64%) women, mean±SD age 35±11 years, weight 75.5±17.1 kg, height 168.5±10.0 cm, and body mass index 26.5±5.2 kg/m2. When comparing active stations to sitting, neurocognitive test either improved or remained unchanged, while
typing speed decreased without affecting
typing errors. Overall results improved after day 1, suggesting habituation. We observed no major differences across active stations, except decrease in average
typing speed 42.5 versus 39.7 words per minute with standing versus stepping (P=0.003).
CONCLUSIONS: Active workstations improved cognitive performance, suggesting that these workstations can help decrease sedentary time without work performance impairment.
