Effect of Relaxation Breathing on Glycemic Response in Type II Diabetic Subjects

TL;DRAbstract

Background Pharmacological treatments are often used to improve hyperglycemia in Type II diabetics. Stress is associated with development of insulin resistance and hyperglycemia. Non‐pharmacological interventions that reduce stress could improve glycemic response. This study determined if a standard relaxation breathing (RB) exercise could improve glycemic response in non‐insulin dependent Type II diabetics. Methods Subjects (n=9; 62.0 ± 9.3 yrs; BMI 31.0 ± 6.5) were randomized in a double‐cross over design. Following a 9 hour fast from food/medications and a 30 min acclimation period of control breathing (CB) or RB, baseline blood glucose was measured (0 min) prior to an oral glucose tolerance test drink (OGTT; 50g/240mL). Blood glucose was measured 30, 60, 120 min post OGTT. RB consisted of sequentially increasing exhalation durations (1, 2, …10 sec) repeated every 10 min for 20 min pre‐OGTT and every 10 min for 120 min post OGTT. Results Blood glucose at 0, 30, 60 and 120 min was 15
