Many overestimate exercise intensity, study shows

Summary:
Do you work out for health benefits and feel you are exercising more than enough? You might be among the many who overrate how hard they work out or underestimate what moderate intensity exercise means, according to a recent study. "This is worrisome both for personal and public health and well-being," remarks one expert.

Do you work out for health benefits and feel you are exercising more than enough? You might be among the many Canadians who overrate how hard they work out or underestimate what moderate intensity exercise means, according to a recent study out of York University's Faculty of Health.

"Our study findings suggest that the majority of young and middle-aged to old adults underestimate the intensity of physical activity that is required to achieve health benefits," says Professor Jennifer Kuk, School of Kinesiology and Health Science. "This is worrisome both for personal and public health and well-being."

The 129 sedentary adult ages 18 to 64 recruited for the study, irrespective of their sex, ethnicity or BMI classifications, correctly estimated physical activities of light effort but underestimated moderate and vigorous effort, even after being given commonly used exercise intensity descriptors.

"We instructed volunteers to walk or jog on the treadmill at a speed which they felt corresponded to the 'light,' 'moderate' and 'vigorous' intensity descriptors used in the physical activity guide, yet they underestimated how hard they should be working to achieve moderate and vigorous intensity," lead researcher and graduate student Karissa Canning says.

Health Canada, as well as global physical activity guidelines using general terms to describe exercise intensity (determined by a given percentage of the maximum heart rate of an individual), recommend that adults ages 18 to 64 years should participate in two-and-a-half hours of moderate to vigorous physical activity per week for 10 minutes or longer at a stretch.

For adults to achieve a moderate intensity, their heart rates should be within the range of 64 to 76 per cent of their maximum heart rate and between 77 to 83 per cent for vigorous intensity, according to the Canadian and global physical activity guidelines.

Though there has been ample research that helped to develop the current guidelines, it is unclear whether individuals actually understand them as intended, notes Canning.

The Heart and Stroke Foundation funded study, "Individuals Underestimate Moderate and Vigorous Intensity Physical Activity" was recently published in PLOS ONE.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
