目的：久坐与体重增加和肥胖有关。跑步机办公桌是一个站立的办公桌和跑步机的组合，让员工工作，而步行在低速。设计和方法：假设是，1年的干预与跑步机办公桌与员工的日常体力活动（每分钟的所有活动的总和）和减少每天久坐不动的时间（零活动）的增加。员工（n = 36; 25名妇女，11名男子）（87 +/- 27 kg，BMI 29 +/- 7 kg/m（2），n = 10瘦BMI < 25 kg/m（2），n = 15超重25 < BMI < 30 kg/m（2），n = 11名体重指数> 30 kg/m2的肥胖者）自愿将他们的传统办公桌换成跑步机办公桌，以促进身体活动，为期1年。每日体力活动（使用加速度计），工作表现，身体成分和血液变量在基线和6个月和12个月后，跑步机台干预。使用跑步机办公桌的受试者的每日体力活动从基线的3，353 +/-1，802活动单位（Au）/天增加到6个月时的4，460 +/-2，376 Au/天（P < 0.001），12个月时的4，205 +/-2，238 Au/天（P < 0.001）。使用跑步机办公桌与每日久坐时间（零活动）显著减少相关，从基线时的1，020 +/- 75分钟/天减少到6个月时的929 +/- 84分钟/天（P < 0.001）和12个月时的978 +/- 95分钟/天（P < 0.001）。整个组的体重平均减轻1.4 +/- 3.3公斤（P < 0.05）。肥胖受试者的体重减轻为2.3 ± 3.5 kg（P < 0.03）。与传统的基于椅子的办公桌相比，使用跑步机办公桌与日常身体活动增加有关;它们的部署与性能改变无关。对于36名参与者，脂肪量没有显着变化，然而，那些减肥的人（n = 22）减少了3.4 +/- 5.4 kg（P < 0.001）的脂肪量。结论：使用跑步机办公桌可以改善办公室工作人员的健康状况，而不会影响工作表现。
Objective: Sedentariness is associated with weight gain and obesity. A treadmill desk is the combination of a standing desk and a treadmill that allow employees to work while walking at low speed.Design and Methods: The hypothesis was that a 1-year intervention with treadmill desks is associated with an increase in employee daily physical activity (summation of all activity per minute) and a decrease in daily sedentary time (zero activity). Employees (n = 36; 25 women, 11 men) with sedentary jobs (87 +/- 27 kg, BMI 29 +/- 7 kg/m(2), n = 10 Lean BMI < 25 kg/m(2), n = 15 Overweight 25 < BMI < 30 kg/m(2), n = 11 Obese BMI > 30 kg/m(2)) volunteered to have their traditional desk replaced with a treadmill desk to promote physical activity for 1 year.Results: Daily physical activity (using accelerometers), work performance, body composition, and blood variables were measured at Baseline and 6 and 12 months after the treadmill desk intervention. Subjects who used the treadmill desk increased daily physical activity from baseline 3,353 +/- 1,802 activity units (AU)/day to, at 6 months, 4,460 +/- 2,376 AU/day (P < 0.001), and at 12 months, 4,205 +/- 2,238 AU/day (P < 0.001). Access to the treadmill desks was associated with significant decreases in daily sedentary time (zero activity) from at baseline 1,020 +/- 75 min/day to, at 6 months, 929 +/- 84 min/day (P < 0.001), and at 12 months, 978 +/- 95 min/day (P < 0.001). For the whole group, weight loss averaged 1.4 +/- 3.3 kg (P < 0.05). Weight loss for obese subjects was 2.3 +/- 3.5 kg (P < 0.03). Access to the treadmill desks was associated with increased daily physical activity compared to traditional chair-based desks; their deployment was not associated with altered performance. For the 36 participants, fat mass did not change significantly, however, those who lost weight (n = 22) lost 3.4 +/- 5.4 kg (P < 0.001) of fat mass. Weight loss was greatest in people with obesity.Conclusions: Access to treadmill desks may improve the health of office workers without affecting work performance.
