No one doubts the positive health effects of regular moderate-to-vigorous physical activity (MVPA), but now researchers are finding that even light physical activity can reduce the risk of coronary heart disease and cardiovascular disease. The latest findings, focused on women age 65 and older, echo revised US Department of Health and Human Services (HHS) activity guidelines strongly supported by APTA.
The recent study, published in JAMA Network Open, asked 5,861 women with an average age of 78.5 years to wear a hip accelerometer for a week to establish PA rates, and then tracked rates of later coronary heart disease (CHD) and cardiovascular disease (CVD) for nearly 5 years. Researchers were particularly interested in the effect of light physical activity (PA)—between 1.6 and 2.9 metabolic equivalent tasks (METs)—on the risk of experiencing CVD and CHD.
Researchers divided the participants into 4 groups based on the average amount of time spent per day in light PA: 36-236 minutes, 235-285 minutes, 286-333 minutes, and 334-617 minutes. They also tracked rates of MVPA, as well as demographic, educational, and health information including the presence of chronic conditions, alcohol consumption, smoker or nonsmoker status, and use of antihypertensive and antilipidemic medications. The population studied was a mix of white (48%), black (33.5%), and Hispanic (17.6%) women.
New research combining postmortem examination of brain tissue with testing during life has revealed what researchers believe to be an as-yet unexplained connection: higher levels of physical activity (PA) and motor skills seem to create a “cognitive reserve” that buoys cognitive performance during life, even in the presence of Alzheimer’s disease (AD), Lewy body disease, and other brain pathologies associated with dementia.
For the study, published ahead of print in Neurology, researchers examined brain tissue from 454 participants involved in the Rush Memory and Aging Project (MAP). The subjects participated in a battery of annual clinical assessments and agreed to brain donation at the time of death. The clinical tests included 21 cognitive assessments, an analysis of 10 motor abilities, and an estimation of total daily PA drawn from accelerometers worn constantly for 10 days (researchers in this study used only the first 7 days’ data).
Exercise is a vital element of a healthful lifestyle; it helps maintain heart health, improve mood, and fight weight gain. New research also suggests that it can protect a person’s cognitive skills, and a new study uncovers fresh information as to how this can happen.
According to a study covered on Medical News Today last year, engaging in regular, leisurely exercise can help keep the body young and healthy.
The same appears to be true for the relationship between exercise and the mind; only 10 minutes of physical activity may boost cognitive function in the short-term.
Meanwhile, exercising regularly for 6 months could actually reverse the symptoms of mild cognitive impairment.
An initiative adopted by Lancaster University to embed physical activity into the training for medical students has been showcased at a national and international level.
Lancaster Medical School was the firstschool in the UK to fully embed the Movement For Movement physical activity resources into the undergraduate programme and all medical schools and schools of health now have access to the resources, reaching a potential 120,000 students across the UK.
This Movement For Movement initiative, led by Ann Gates has been shared with all medical schools and visits to a sample of schools was funded by Public Health England and Sport England.
You want blunt? The US Department of Health and Human Services can do blunt—at least when it comes to physical activity (PA) recommendations for Americans.
“Adults should move more and sit less throughout the day,” HHS says in its latest edition of nationwide guidelines for PA. “Some physical activity is better than none.”
That’s the bottom-line recommendation that HHS rolled out this week in its revised Physical Activity Guidelines for Americans. And there’s arguably little room for nuance: according to HHS, 80% of all Americans are not meeting current PA recommendations, a failure that is contributing the prevalence of a host of chronic health conditions.
The new guidelines, with their emphasis on the importance of movement to prevent disease and extend life no matter an individual’s age, echo many perspectives long-championed by APTA and its members.
In a nutshell previous studies have demonstrated an association between low grip strength and poor health outcomes (in other words increased mortality). On the whole previous studies have had too small sample sizes to detect disease specific mortality and have been unable to clearly show relationship with age. The Biobank study has an adequate number of participants, some 500,000, to be able to detect disease and age specific nuances in this relationship.
Some serious math too place in the analysis of the study’s findings and I’m not the one to talk you through the finer details. In essence lower grip strength was strongly associated with adverse health outcomes. This was consistent between gender and remained robust after adjustment for socioeconomic factors. Compared to other commonly used tools grip strength is arguably as reliable as systolic BP and low levels of physical activity to predict a person’s poor overall health.
Better, but still plenty of room for improvement—that’s the US Center for Disease Control and Prevention’s (CDC’s) take on a recent analysis of the rate at which health care providers are counseling patients with arthritis to engage in physical activity (PA). The good news: the percentage of individuals with arthritis who received provider counseling for exercise grew by 17.6% between 2002 and 2014. The bad news: even after that growth, nearly 4 in 10 patients with arthritis still aren’t receiving any information from their providers on the benefits of PA.
The CDC analysis, which appeared in a recent edition of its Morbidity and Mortality Weekly Report, uses data from the National Health Interview Survey gathered in 2002 and 2014. In those years, the survey included a question on whether respondents had been told they have “arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia,” as well as a question asking whether “a doctor or other health professional [has] ever suggested physical activity or exercise to help your arthritis or joint symptoms?”
It’s no secret that physical activity (PA) can decrease the risk of cardiovascular disease (CVD) in middle-aged adults, but researchers in England have found that the relationship also applies to the elderly, and that even small amounts of PA can markedly lower the chances of CVD hospitalization and death in this age group.
Researchers used data from the EPIC study, a 10-country prospective population study, to track CVD-related hospitalizations and deaths among 24,502 participants, aged 39-79 years, and compare those with participants’ self-reported PA. This isn’t the first study of its kind, but authors believe it is notable because of its focus on participants 65 and older, and its 18-year median follow-up duration—a relatively long time span that allowed researchers to follow some participants into old age. Findings were published in the European Journal of Preventive Cardiology.
Would you say that you are physically more active, less active, or about equally active as other people your age?
Your answer might be linked to your risk of premature death decades from now — no matter how physically active you actually are, according to research by Stanford scholars Octavia Zahrt and Alia Crum.
The research, appearing July 20 in Health Psychology, finds that people who think they are less active than others in a similar age bracket die younger than those who believe they are more active — even if their actual activity levels are similar.
