最近,据美国疾病控制与预防中心(Centers for Disease Control and Prevention,CDC)公布的一项数据表明:在美国,有7,900多万成年人有罹患糖尿病的前期征兆,并今后可能会真正患上糖尿病。随着患糖尿病的数量不断爬升,各国研究人员一直希望能发现糖尿病发病率逐年上升的确切原因。
近日,一项研究表明:缺乏体育运动或是2型糖尿病发病的重要原因之一,我们假如很少参加日常体育锻炼的话,我们机体自身调控血糖的能力会有所降低。
这项研究证实了机体的运动对于维持我们日常的血糖水平非常重要。血糖水平高是2型糖尿病的一大致病危险因子,血糖水平过高会引发心血管疾病。我们用餐后,体内血糖会急剧上升,当血糖值高过规定的水平时就会形成高血糖症。研究人员分别考查了运动量较少的人以及运动量正常的人饱餐后体内血糖水平,结果表明当身体健康的人在短短三天时间内运动量减少一半的话,那么他们的用餐后血糖水平就会增高一倍。
研究人员称:一次运动程度中等的锻炼能帮助我们降低机体血糖水平,维持血糖稳态。但一段时间我们不运动的话,上述血糖稳态会被打破,血糖会升高。
最新数据显示美国人每天只步行5,000步,而这项研究证实要想合理控制血糖水平,我们最好每天步行10,000步。而当长时间缺乏体育运动的话,我们机体血糖调节能力会下降,这样一来患糖尿病的危险会上升。
总的来说这项研究显示身体运动可直接影响我们健康情况,要想预防糖尿病那就得多参加锻炼。

Introduction: Postprandial glucose (PPG) is an independent predictor of cardiovascular events and death, regardless of diabetes status. Whereas changes in physical activity produce changes in insulin sensitivity, it is not clear whether changes in daily physical activity directly affect PPG in healthy free-living persons.
Methods: We used continuous glucose monitors to measure PPG and PPG excursions (ΔPPG, postmeal ? premeal blood glucose) at 30-min increments after meals in healthy habitually active volunteers (n = 12, age = 29 ± 1 yr, body mass index = 23.6 ± 0.9 kg·m2, V˙O2max = 53.6 ± 3.0 mL·kg1·min1) during 3 d of habitual (≥10,000 steps per day) and reduced (<5000 steps per day) physical activity. Diets were standardized across monitoring periods, and fasting-state oral glucose tolerance tests (OGTT) were performed on the fourth day of each monitoring period.
Results: During 3 d of reduced physical activity (12,956 ± 769 to 4319 ± 256 steps per day), PPG increased at 30 and 60 min after a meal (6.31 ± 0.19 to 6.68 ± 0.23 mmol·L?1 and 5.75 ± 0.16 to 6.26 ± 0.28 mmol·L?1, P < 0.05 relative to corresponding active time point), and ΔPPG increased by 42%, 97%, and 33% at 30, 60, and 90 min after a meal, respectively (P < 0.05). Insulin and C-peptide responses to the OGTT increased after 3 d of reduced activity (P < 0.05), and the glucose response to the OGTT did not change significantly.
Conclusions: Thus, despite evidence of compensatory increases in plasma insulin during an OGTT, ΔPPG assessed by continuous glucose monitoring systems increased markedly during 3 d of reduced physical activity in otherwise healthy free-living individuals. These data indicate that daily physical activity is an important mediator of glycemic control, even among healthy individuals, and reinforce the utility of physical activity in preventing pathologies associated with elevated PPG.
