Short Walks After Meals Could Help Control Glucose Levels in Older Adults
By Kelly Young
Short bouts of walking after meals may be more effective than a single longer walk in controlling postprandial hyperglycemia in older adults, according to a study in Diabetes Care.
Ten inactive adults (mean age, 69) with fasting blood glucose levels between 105 and 125 mg/dL completed three separate treadmill programs: walking for 15 minutes after every meal; for 45 minutes at 10:30 a.m.; and for 45 minutes at 4:30 p.m. Each program took place over 2 days in a laboratory, with the first day acting as the control and the second as the exercise day.
The 45-minute morning walk and the shorter, thrice daily walks similarly improved 24-hour glycemic control over the control day, but the shorter walks were more effective than the longer walks in reducing 3-hour postprandial glucose levels.
The authors call the effects of shorter, frequent walking bouts "substantial," noting that older adults may feel more comfortable with such a regimen.
