背景。体力活动 (PA) 已被证明有益于葡萄糖耐量。步行是一种方便、低影响的 PA 模式，据报道是糖尿病患者最常进行的活动。本研究的目的是确定持续 8 周每天积累 10,000 步的建议是否能有效改善超重、缺乏运动的女性的葡萄糖耐量。方法。 18 名有 2 型糖尿病家族史的女性（53.3 +/- 7.0 岁，35.0 +/- 5.1 kg/m(2)）完成了为期 4 周的控制期，随后进行了 8 周的步行计划，饮食没有改变。步行计划的目标是每天累计至少 10,000 步，由计步器监测。结果。在控制期间，参与者每天行走 4972 步。在干预期间，参与者将每天的累计步数增加了 85%，达到 9213，这导致 2 小时负荷后血糖水平 (P < 0.001)、AUC(葡萄糖) (P < 0.025)、收缩压 (P < 0.001) 和舒张压 (P = 0.002) 发生有益变化。步行干预期间体重、体脂百分比和腰围没有变化。结论。对于有 2 型糖尿病风险的超重女性来说，每天 10,000 步的建议可改善葡萄糖耐量并降低收缩压和舒张压。这表明活动可以在一天中积累，并且不必导致体重减轻即可使该人群受益。 (C) 2003 美国健康基金会和 Elsevier Inc. 保留所有权利。
Background. Physical activity (PA) has been shown to benefit glucose tolerance. Walking is a convenient low-impact mode of PA and is reported to be the most commonly performed activity for those with diabetes. The purpose of this study was to determine whether a recommendation to accumulate 10,000 steps/day for 8 weeks was effective at improving glucose tolerance in overweight, inactive women.Methods. Eighteen women (53.3 +/- 7.0 years old, 35.0 +/- 5.1 kg/m(2)) with a family history of type 2 diabetes completed a 4-week control period followed by an 8-week walking program with no changes in diet. The walking program provided a goal of accumulating at least 10,000 steps/day, monitored by a pedometer.Results. During the control period, participants walked 4972 steps/day. During the intervention period, the participants increased their accumulated steps/day by 85% to 9213, which resulted in beneficial changes in 2-h postload glucose levels (P < 0.001), AUC(glucose) (P 0.025), systolic blood pressure (P < 0.001), and diastolic blood pressure (P = 0.002). There were no changes in body mass, body fat percentage, and waist circumference during the walking intervention.Conclusions. The 10,000 steps/day recommendation resulted in improved glucose tolerance and a reduction in systolic and diastolic blood pressure in overweight women at risk for type 2 diabetes. This demonstrates that activity can be accumulated throughout the day and does not have to result in weight loss to benefit this population. (C) 2003 American Health Foundation and Elsevier Inc.
