Both low intensity and high intensity workouts effective for weight loss

Patients at risk for diabetes or heart disease may want to choose their workout intensity based on health goals, according to an article being published in .

Exercise has been shown to reduce obesity and related , but whether increasing exercise intensity improves outcomes has not been determined. Researchers studied 300 abdominally obese adults to determine the separate effects of exercise amount and intensity on abdominal obesity and . Participants were randomly assigned to perform either short, high or long, lower five times a week. All participants were instructed to eat a healthy diet during the study but did not reduce their caloric intake. After 24 weeks, all participants experienced similar reductions in waist circumference, but only participants in the high group experienced reduction in two-hour glucose levels.

According to lead study author, Robert Ross, PhD, of the School of Kinesiology and Health Studies at Queen’s University in Kingston, Ontario, the results show a clear benefit to higher intensity workouts for those who wish to reduce glucose levels. For those who may think that are too difficult, Dr. Ross has good news. “Higher intensity can be achieved simply by increasing the incline while walking on a treadmill or walking at a brisker pace,” he said. “Participants were surprised by how easy it was for them to attain a high intensity exercise level.”
