The Answer to Obesity at Your Fingertips

Working out in intervals of intense activity may be heart-friendly

(RxWiki News) Exercising and healthy eating is essential to losing weight. How often do people enjoy working out though? Eating healthy may be manageable, but making the time to work out is becoming more difficult for everyday people.

New research combined interval training with healthy eating to significantly reduce risk factors associated with cardiovascular disease.

"Start your working out slowly; gradually increase effort."

The Montreal Heart Institute’s Center for Preventive Medicine and Physical Activity (EPIC centre) studied a number of patients to determine the effects interval training and healthy eating would have on contributing to better health.

Obesity increases risk for many health problems including: cardiovascular disease, type 2 diabetes, stroke, hypertension, and cancer. Lowering an individual’s overall body mass would help lower the risks for diseases.

Many people have trouble figuring out or even making the first move to lowering body mass.

Interval training consists of alternating between short periods of intense effort and rest periods. With interval training, participants were able to increase their efforts for longer periods of time.

It was more manageable to do interval training than continuous exercise. Weight loss was achieved with interval training and eating healthier.

The Study

  • The Montreal Heart Institute’s Center for Preventive Medicine and Physical Activity (EPIC centre) conducted research on 62 participants
  • The study lasted 9 months
  • Improvements were seen in body mass, waist circumference, body mass index (BMI), and effort capacity
  • On average, participants were able to lose 5.5 percent of body mass, reduce waist circumference by 5.15 percent, and increased effort capacity to 15 percent
  • Participants were able to decrease bad cholesterol (LDL) by 7 percent and increase good cholesterol (HDL) by 8 percent
  • Decrease in body mass by exercising and eating healthy will reduce risk factors associated with cardiovascular disease
