A collaborative study between Columbia University Medical Center and National Public Radio has examined the impact of short walking intervals on the physiological and psychosocial effects of prolonged sitting.

哥倫比亞大學醫學中心與美國國家公共廣播電台的一項合作研究，探討了短時間步行對長時間久坐所產生的生理及心理社會影響。

The research was predicated on the established correlation between sedentary behavior and adverse health outcomes, including hypertension, hyperglycemia, and increased risks of cardiovascular disease and obesity. Prior laboratory data indicated that five-minute walks at a velocity of 2 miles per hour every 30 minutes could reduce postprandial blood glucose spikes by approximately 60%. However, the practical application of such a regimen within contemporary professional and social structures remained an unresolved variable.

該研究是以久坐行為與不良健康結果之間的既有相關性為前提，包括高血壓、高血糖，以及心血管疾病與肥胖風險的增加。先前的實驗室數據顯示，每 30 分鐘以每小時 2 英里的速度步行 5 分鐘，可將餐後血糖峰值降低約 60%。然而，在現代專業與社交結構中，此類方案的實際應用仍是一個尚未解決的變數。

To address this, a pragmatic intervention involving approximately 20,000 participants across the United States was implemented. Subjects adhered to movement protocols at intervals of 30, 60, or 120 minutes. The methodology employed the 'Feasibility, Acceptability and Appropriateness of Intervention Measures' questionnaire to quantify implementation potential. While the 30-minute frequency yielded the most significant improvements in mood and fatigue, it demonstrated the lowest compliance rates. Conversely, the 120-minute interval was the most feasible but least effective. The 60-minute cadence was identified as the optimal equilibrium, providing significant psychosocial benefits—including a 25% reduction in reported fatigue and a 4% increase in productivity—without compromising professional performance.

為了解決這一問題，研究人員在全美實施了一項涉及約 20,000 名參與者的務實干預措施。受試者遵循每 30、60 或 120 分鐘一次的活動方案。該方法採用「干預措施的可行性、可接受性與適切性」問卷來量化實施潛力。雖然 30 分鐘一次的頻率在改善情緒與疲勞方面效果最顯著，但其遵行率最低。相反地，120 分鐘的間隔最可行，但效果最差。60 分鐘的節奏被認定為最佳平衡點，在不損害專業表現的情況下，提供了顯著的心理社會益處——包括報告的疲勞感減少 25% 以及生產力提高 4%。

Beyond clinical metrics, the study suggests institutional implications for educational and corporate environments. The integration of movement breaks was observed to facilitate media literacy and scientific inquiry in pedagogical settings. Furthermore, the data suggests that the widespread adoption of these intervals could serve as a non-invasive public health strategy to counteract the systemic health degradation associated with modern screen-centric lifestyles.

除臨床指標外，研究還提出了對教育與企業環境的制度性建議。研究觀察到，在教學環境中整合活動休息時間有助於提升媒體素養與科學探究。此外，數據顯示，廣泛採用這些休息間隔可作為一種非侵入性的公共衛生策略，以對抗與現代螢幕中心生活方式相關的系統性健康退化。

The study concludes that hourly five-minute walking breaks are a viable and effective method for reducing the harms of prolonged sedentariness.

研究結論認為，每小時 5 分鐘的步行休息是一種可行且有效的方法，能減輕長期久坐的危害。
