It just seems too good to be true. Study after research study consistently promoting the endless benefits of exercise. Couch potatoes everywhere are waiting for the other shoe to drop, telling us that all of those scientists were wrong and we should remain as sedentary as possible.
Yet four additional studies released recently each give the same prescription for improving some aspect of your health: exercise.
They add to recent evidence that regular workouts can improve old brains, raise kids' academic performance and give a brain boost to everyone in between.
Better bonesOne study illustrates the effect of exercise on preventing or limiting osteoporosis, which affects more than 200 million people worldwide. Researchers at the University of Missouri found that while both resistance training (lifting weights) and high impact exercise (running) both help build needed bone mineral density (BMD), running is the better choice.
"Exercise programs to increase bone strength should be designed using what is known about how bones respond to exercise," said Pam Hinton, associate professor and lead author. "Only the skeletal sites that experience increased stress from exercise will become stronger. High-impact, dynamic, multi-directional activities result in greater gains in bone strength."
The study was published in the February issue of the Journal of Strength Conditioning.
Less painIn a related study, exercise seemed to be one of the few successful remedies for those that suffer from low-back pain. In the February issue of the Spine Journal, University of Washington physicians summarized 20 different clinical trials that promoted different solutions to alleviating pain.
"Strong and consistent evidence finds many popular prevention methods to fail while exercise has a significant impact, both in terms of preventing symptoms and reducing back pain-related work loss," said Dr. Stanley J. Bigos, professor emeritus of orthopaedic surgery and environmental health. "Passive interventions such as lumbar belts and shoe inserts do not appear to work."
Better eye healthAlso, vigorous exercise has now been linked with significantly reduced onset of cataracts and age-related macular degeneration. In the study, detailed in Investigative Ophthalmology and Visual Science, researchers reviewed the eye health of 41,000 runners over seven years and found that both men and women had significantly lower rates of these two diseases than the general public.
Men who logged more than 5.7 miles per day had a 35 percent lower risk than those that ran less than 1.4 miles per day. While the correlation is strong, the reason is not clear.
"We know some of the physiological benefits of exercise, and we know about the physiological background of these diseases, so we need to better understand where there's an overlap," said Paul Williams, an epidemiologist in the Lawrence Berkeley National Laboratory Life Sciences Division.
