简介：运动对肥胖和糖尿病的治疗有有益的影响。然而，肥胖受试者不密切遵守训练计划，可能是因为经常提出的连续运动的单调性。为了增加对训练计划的坚持，间歇性运动，这是不那么单调，可能更合适。目的：本研究的目的是确定感觉上不太难的运动（连续与间歇性运动），并分析训练计划的基础上，这种运动在肥胖妇女和2型糖尿病。方法：选择2型糖尿病肥胖女性和非糖尿病肥胖女性各20例。在每组中，10名患者整合了训练计划（即，训练组），而其余的患者是未经训练的（即，对照组）。训练组进行了连续运动和间歇运动，以确定由于较低的感知用力（RPE）评级而导致的感知较轻的运动。然后，向训练组提出包括32 min（3 d.wk（-1. 10 wk（-1）的感知强度较低的运动的训练计划。结果如下：在间歇性运动期间，与患有或不患有糖尿病的肥胖女性的持续运动相比，RPE显著较低（RPE分别为12.3 +/-2.3 vs 13.7 +/- 2.3和RPE 11.9 +/- 1.1 vs 13.2 +/- 1.6）。训练计划后，对糖化血红蛋白有明显的有益影响（6.8 ± 1.4% vs 6.5 ± 1.2%），体重（97.1 +/- 16.9 vs 95.2 +/- 16.2 kg）、体重指数（37.6 +/- 6.1 vs 36.8 +/- 6.0 kg.m（-2））以及心率和步行距离限制。结论：患有或不患有糖尿病的肥胖女性认为间歇性运动比持续运动难度小，基于间歇性运动的训练计划对肥胖和2型糖尿病产生了有益的影响。
Introduction: Exercise has beneficial effects on obesity and diabetes treatments. However, obese subjects do not closely adhere to training programs probably because of the monotony of the continuous exercise that is frequently proposed. To increase adherence to training programs, intermittent exercise, which is less monotonous, may be more appropriate. Purpose: The purposes of this study were to determine the perceptually less hard exercise (continuous VS intermittent exercise) and to analyze the impact of a training program on the basis of this exercise in obese women with and without type 2 diabetes. Methods: Twenty type 2 diabetic obese women and 20 obese women without diabetes were recruited. In each group, 10 patients integrated a training program (i.e., training groups), whereas the remaining patients were untrained (i.e., control groups). The training groups performed a continuous exercise and an intermittent exercise to determine the perceptually less hard exercise thanks to lower ratings of perceived exertion (RPE). Then, a training program that included 32 min (3 d.wk(-1).10 wk(-1)) of the perceptually less hard exercise was proposed to training groups. Results: RPE were significantly lower during the intermittent exercise compared to the continuous exercise in the obese women with or without diabetes (RPE = 12.3 +/- 2.3 vs 13.7 +/- 2.3 and RPE 11.9 +/- 1.1 vs 13.2 +/- 1.6, respectively). After the training program, significant beneficial effects on the glycosylated hemoglobin (6.8 +/- 1.4% vs 6.5 +/- 1.2%), body mass (97.1 +/- 16.9 vs 95.2 +/- 16.2 kg), body mass index (37.6 +/- 6.1 vs 36.8 +/- 6.0 kg.m(-2)), and on the HR and the walked distance limit were noticed in the training groups. Conclusion: The obese women with or without diabetes perceived the intermittent exercise as being less hard than the continuous exercise, and a training program based on intermittent exercises produced beneficial effects on obesity and type 2 diabetes.
