According to the research three 15 minutes post meal walks is more beneficial to lower the glucose level than 45 min of sustained
walking. Post meal walks are more beneficial in controlling increase in blood sugar following a meal (postprandial hyperglycemia).
Especially in older people who has greater risk of glucose intolerance are more benefited from this technique as it controls rise in sudden blood sugar after meal. The study was done on inactive older (more than 60 years) and were non smoking. According to the result of the study both 45 minutes of sustained walking and 15 minutes of post meal walk three time a day improved the glucose level in blood but post meal walking was significantly more effective than 45 min of sustained morning or afternoon walking in lowering 3-hour post dinner glucose.
Note - In this study older people walked at a moderate pace, not a brisk walk and not a leisurely stroll.
Recently, considerable attention has been focused on the postprandial (increase in blood sugar level after lunch or dinner)
state, because isolated postprandial hyperglycemia, as occurs in people
with impaired glucose tolerance, has been shown to double the risk for
death from cardiovascular disease
and because postprandial hyperglycemia appears to be the rate-limiting
factor for achieving optimal glycemic control in patients with type 2
diabetes.
“The post-meal exercise was especially efficient at lowering the 3-hour
post-dinner blood sugar glucose,” said the study’s lead author Dr.
Loretta DiPietro, chair of the department of exercise science at George
Washington University School of Public Health and Health Services.
