Arterial stiffness, which increases with sedentary living, is associated with higher risk of heart disease. It’s well known that exercise can help, but how much—or how little—is enough?
“While near-daily, vigorous lifelong (>25 years) endurance exercise training prevents arterial stiffening with ageing, this rigorous routine of exercise training over a lifetime is impractical for most individuals,” noted the authors of a new study, which aimed to determine the least amount of exercise necessary to reduce arterial stiffness.
Research has supported exercise as having the potential to keep dementia at bay or at least to impede its progression. A recent study suggests that physical activity may not be as effective at warding off cognitive decline as previously thought.
In this study, published in BMJ (2018; 361, k1675), 329 individuals were assigned to an exercise intervention, while 165 subjects received “usual care.” Average age was 77, and each participant had a clinically confirmed dementia diagnosis.
Want to outwalk the grim reaper? Pick up the pace, say researchers. A new study from the United Kingdom suggests that quicker walking may add years to your life.
The study’s primary aim was to examine the impact of walking pace and volume on all-cause mortality. To determine this, researchers looked at mortality records for 50,225 individuals from Scotland and England who had self-reported their walking data via interview.
Could a cure for depression be found in the weight room? Data from a study published in JAMA Psychiatry (2018; 75 , 566–76) points to that conclusion. The meta-analysis of 33 clinical trials, featuring 1,877 participants, found a link between resistance training (RET) and a reduction in depressive symptoms.Read More
It will soon be easier for consumers to make better food and beverage decisions when eating out or on the go. The U.S. Food and Drug Administration (FDA) has moved forward with a food labeling law that requires restaurants, grocery stores and convenience stores with 20 or more locations to post calorie counts for standard menu items. Proponents say calorie disclosures on everything from muffins to lattes to Happy Meals will offer more transparency and will likely encourage diners to downsize their consumption.Read More
Our bodies host a huge population of microorganisms, dubbed the human microbiome. In recent years, the makeup of critters in our guts has been linked to a plethora of conditions, including depression, heart disease and obesity. And now bug-friendly scientists at the University of California, San Diego School of Medicine have presented initial findings from the American Gut Project, a crowdsourced initiative that analyzes people’s survey responses and fecal samples to better understand how things like diet, lifestyle and disease affect the human microbiome.Read More
Here’s another good reason for people to reduce their Buddha-bellies: improving their vitamin D status. According to data presented at the 2018 European Society of Endocrinology’s annual meeting in Barcelona, Spain, researchers from the Netherlands found that more body fat around adults’ waistline is associated with lower vitamin D levels. Beyond raising the risk of weak bones, poor vitamin D status could set the stage for other health issues, including heart disease and compromised immunity.Read More
Question: I have a sensitivity or allergy to tomatoes. My mouth and esophagus get itchy and sore when I eat them. Is there any way to make tomatoes less irritating? Is there a good substitute for tomatoes in recipes?
Answer: You may suffer from oral allergy syndrome (OAS), a relatively common reaction to plant foods, including tomatoes. People who have pollen allergies are more likely to have OAS (Asero 2013) because they react to similar proteins in vegetables, fruits and/or nuts.
No wonder social media feeds are packed with pictures of overflowing smoothie bowls: It appears people feel the types of foods they consume play a bigger role in their health goals than the volume they eat. As a result, a study from Vanderbilt University published in Management Science suggests that those who are trying to maintain a healthy body weight or wishing to shed a few pounds might be prone to overeating “healthy” items like nuts, granola and avocados. The upshot: The public should be educated about practicing portion control—for foods of all kinds.Read More
Many people can’t resist the temptation of homemade chocolate chip cookies in the break room or leftover Halloween candy circulating among the cubicles. A Centers for Disease Control and Prevention study of 5,222 employees across the U.S., using data from the U.S. Department of Agriculture’s National Household Food Acquisition and Purchasing Survey, documented this challenge.Read More
New research suggests that endurance exercise positively affects the gut microbiome, but only for lean individuals and only for as long as exercise continues. Researchers at the University of Illinois at Urbana-Champaign conducted the study with 32 sedentary men and women—some lean, some obese. The purpose was to explore the impact of endurance exercise on the composition, functional capacity and metabolic output of gut microbiota. Investigators collected samples from the subjects before and after 6 weeks of exercise, then after 6 weeks of no exercise.Read More
Enforcing bedtime rules may be an important factor in helping kids maintain healthy weight levels. A comprehensive research review of 42 studies with 75,499 participants, conducted by University of Warwick researchers in Coventry, England, found that short sleep durations in infants, children and adolescents were a risk factor for gaining weight and developing obesity. Data analysis showed that children and teens who slept less than others of the same age gained more weight as they grew older and were more likely to become overweight or obese.Read More
Substance use disorder can wreak havoc on people’s lives. Fitness activity can be a
transformative way for those in recovery to heal, rebuild their lives and find a community of healthy supporters.
According to a study published in Mental Health and Physical Activity in 2011, patients with substance use disorder who exercised while in recovery reported feeling greater strength, improved health, a sense of accomplishment, and increased confidence about staying clean and sober.
24 Hour Fitness® is partnering with the University of Pennsylvania Behavior Change for Good Initiative [BCFG] to support research into what works best for creating lasting exercise habits. With an interdisciplinary team of world-renowned researchers, the BCFG addresses the broader question of how to make positive behavior change stick in aspects of life related to health, education and savings.Read More
Can we say that inactivity and obesity are directly related? Scientists are still addressing this issue. The 2018 Physical Activity Council Participation Report shows that 82.4 million people—28% of the American population—are inactive. At the same time, the Centers for Disease Control and Prevention reports that more than one-third (36.5%) of U.S. adults are obese (NCHS Data Brief, No. 219, November 2015).Read More
