Resistance exercise can help get better sleep, suggests study

Texas : According to a new study, resistance exercise may be superior to aerobic exercise as a way to get better sleep, and sleep is important for cardiovascular health.
The study was published in the journal, ‘American Health Association’.
“It is increasingly recognized that getting enough sleep, particularly high-quality sleep, is important for health including cardiovascular health. Unfortunately, more than a third of Americans don’t get enough sleep on a regular basis,” said study author Angelique Brellenthin, PhD, assistant professor of kinesiology at Iowa State University in Ames, Iowa.
“Aerobic activity is often recommended to improve sleep, yet very little is known about the effects of resistance exercise versus aerobic exercise on sleep. The U.S. Department of Health and Human Services’ 2018 Physical Activity Guidelines Advisory Committee Scientific Report identified the need for more research into resistance exercise and sleep outcomes. Our study is one of the largest and longest exercise trials in a general adult population to directly compare the effects of different types of exercise on multiple sleep parameters,” he added.
Previous research has confirmed that not getting enough sleep (the recommended amount for adults is seven to eight hours a day) or getting poor quality sleep increases risks for high blood pressure, elevated cholesterol and atherosclerosis, which happens when fatty deposits build up in arteries. Not getting enough sleep is linked to weight gain, diabetes and inflammation, all of which can worsen cardiovascular disease. Sleeping too much or too little also has been shown to increase the risk of stroke, heart attack and death.
For this study, researchers enrolled 386 adults who met the criteria for overweight or obesity, which was a body mass index from 25-40 kg/m2. Participants were inactive and had elevated blood pressure, measuring from 120-139 mm Hg systolic (top number) and 80-89 mm Hg diastolic (bottom number). Participants were randomly assigned to a no-exercise group (for comparison) or one of three exercise groups (aerobic only, resistance only, or combined aerobic and resistance) for 12 months. Everyone in the exercise groups participated in supervised 60-minute sessions, three times a week, with the combination exercise group doing 30 minutes of aerobic and 30 minutes of resistance exercise.
