To combat prediabetes, brisk walking may be superior to jogging
Brisk walking may be better than jogging for patients with prediabetes.
HealthDay News — Brisk walking may be more effective than jogging in controlling blood glucose levels in patients with prediabetes, according to a study published in Diabetologia.
The study included 150 individuals with prediabetes who were divided into 4 groups. One group followed a gold-standard program that included a low-fat, low-calorie diet and moderate-intensity exercise equivalent to 7.5 miles of brisk walking a week. The other participants were assigned to 1 of 3 exercise groups: low amount at moderate intensity equivalent to walking briskly for 7.5 miles a week; high amount at moderate intensity equal to walking briskly for 11.5 miles weekly; and high amount at vigorous intensity equivalent to jogging for 11.5 miles a week.
After 6 months, patients using the 3-pronged approach had an average 9% improvement in oral glucose tolerance. Among those who did exercise only, there was a 7% improvement in the moderate-intensity, 11.5-mile group; a 5% improvement in the moderate-intensity, 7.5-mile group; and a 2% improvement in the vigorous-intensity, 11.5-mile group.
"When faced with the decision of trying to do weight loss, diet, and exercise versus exercise alone, the study indicates you can achieve nearly 80% of the effect of doing all three with just a high amount of moderate-intensity exercise," lead author William Kraus, MD, of the Duke University School of Medicine in Durham, N.C., said in a journal news release. "I was heartened by the fact that I found out that I can give patients one message and they can get nearly the same effect as when required to exercise, diet, and lose weight all at the same time."
