Understanding the acute and cumulative metabolic effects of prolonged sitting in adults

久坐行为（坐着的时间）与慢性疾病的风险增加有关，包括2型糖尿病和肥胖，但最近的证据表明，低强度活动（日常生活中的非运动活动）与降低风险有关。这些研究将检验，通过频繁的短时间活动来打破久坐时间，是否能克服长时间久坐对超重老年人血糖和血脂的负面影响。

Sedentary behaviour (sitting time) has been linked to an increased risk of chronic illnesses, including type 2 diabetes and obesity, but recent evidence suggests that light-intensity activity (non-exercise activities of daily living) is associated with reduced risk. These studies will examine whether breaking up sitting time with frequent short periods of activity can overcome the negative effects of prolonged sitting on blood glucose and blood fats in overweight older adults.
