Just one hour of brisk walking a week can really benefit people with osteoarthritis

02/04/2019

We’ve only just written about how a low-carb diet may help relieve symptoms of knee osteoarthritis and now a new study has revealed that just one hour of brisk walking per week can significantly lower mobility-related disability in people with knee osteoarthritis. According to the research, the findings of which appear in the American Journal of Preventive Medicine, just one hour of weekly exercise lowered the risk of mobility-related disability in seniors with knee osteoarthritis by 85% and that of daily living disability by nearly 45%. For the study, a team of researchers from the Northwestern University Feinberg School of Medicine, in Chicago, IL, led by Dorothy Dunlop, Ph.D., analyzed data from more than 1,500 adults. All of the participants were living with osteoarthritis and experienced aches, pain, and stiffness in their lower extremities as a result. However, none of them had a disability prior to the study. Over a period of four years, the researchers monitored the participants’ levels of physical activity. They found that the seniors who got at least one hour of moderate-to-vigorous activity each week had no trouble performing a range of daily tasks. However, in seniors who did not engage in this much physical activity, 24% could not walk across a street before the traffic lights changed, and 23% struggled to perform their daily morning tasks. Speaking about the findings of the research, Prof. Dunlop said: “We hope this new public health finding will motivate an intermediate physical activity goal. One hour a week is a stepping stone for people who are currently inactive. People can start to work toward that.”

Just 10 minutes of gardening each week could lower your risk of death

21/03/2019

If you’re over 40, just 10 minutes of leisurely activity each week could lower your risk of death from multiple causes. That’s the key finding from a recently published study by researchers from China and the United States. According to the study involving 88,140 US adults, even low-level physical activity, such as gardening, can help people live longer lives. Publishing their findings in the British Journal of Sports Medicine, the researchers said that even people who spend just a short time each week being physically active have a lower risk of death due to cancer, cardiovascular issues and all-cause mortality. However, participating in more vigorous types of exercise, including running and cycling, affords even greater health benefits. Unlike people who were physically inactive, those who undertook between 10 and 59 minutes of moderate, leisurely exercise each week had an 18% lower risk of death from all causes. Those who were physically active for a little longer (between 150 and 299 minutes per week) had a 31% lower risk of all-cause death. Undertaking over 1,500 minutes of physical activity on a weekly basis resulted in a 46% decrease in overall mortality risk. Furthermore, individuals who opted for more vigorous exercise instead of lighter physical activity had a much lower mortality risk still.

Less sitting, more moving tied to longer life

31/01/2019

People who have sedentary jobs could significantly boost their lifespans by taking short, regular movement breaks, a new study has found. It’s no secret that individuals who spend a lot of time sitting down are more likely to develop certain adverse health conditions, such as diabetes, obesity and cardiovascular diseases, as well as having increased risk of osteoporosis, depression, anxiety, colon cancer and high blood pressure. However, just a small amount of exercise, the study suggests, could lower the risk of early death. According to the research – the findings of which are published in the Annals of Internal Medicine – individuals who sat for less than 30 minutes at a time had the lowest risk of early death. For example, workers who had a movement break (involving some low-intensity exercise) every 30 minutes had a 17% lower risk of death than their counterparts who did not have any breaks. Moreover, individuals who broke up periods of sitting every 30 minutes with moderate- to high-intensity exercise lowered their risk of early death by 35%. Speaking about the findings of the research, Keith Diaz, an assistant professor of behavioural medicine at Columbia University Vagelos College of Physicians and Surgeons in New York City and study lead, said: “If you have a job or lifestyle that involves a lot of sitting, you can lower your risk of early death by moving more often, for as long as you want and as your ability allows — whether that means taking an hour-long high-intensity spin class or choosing lower-intensity activities, like walking.”

Exercise can help middle-aged people reverse heart risk

09/01/2018

While many people will be using the start of the New Year to kick-start certain lifestyle changes in an attempt to become “healthier”, there are some who might think it’s too late based on their age. However, a new study has revealed that it’s often not too late for many who want to improve their fitness. In fact, with exercise, even individuals who are into their late middle age can reduce or even reverse the risk of heart failure caused by years of sedentary living. But there’s a slight catch – it requires at least two years of aerobic exercise four to five days a week. According to the study, which was published in the journal Circulation, individuals aged 45-64 who followed an aerobic exercise routine for two years showed an 18% improvement in their maximum oxygen intake while exercising and a more than 25% improvement in "plasticity" in the left ventricular muscle of the heart, compared to their counterparts who didn’t follow such an exercise regime. The take-home message of the research is that exercise needs to be part of a person’s daily routine, like teeth brushing. Dr Richard Siow, vice-dean for the faculty of life sciences and medicine at King's College London, said: "I think that's a very important take-home message for those of us who may have a doom and gloom view there's nothing we can do about it. Yes there is, we can start by getting off the couch to have a more active lifestyle."

Less than 2 hours of walking per week may ‘considerably prolong life’

19/10/2017

We all know that regular exercise should be a part of our weekly routine, but finding the time and motivation is often difficult. But what if just a little bit of walking had the ability to considerably prolong your life? Would you make time then? A new study published in the American Journal of Preventive Medicine suggests that even as little as two hours of walking a week, compared with no physical activity at all, correlated with a lower risk of all-cause mortality. In other words, even levels of walking that do not meet government-issued guidelines still provide significant benefits and lower the risk of premature death by a considerable amount. Moreover, the study also found that going beyond government exercise guidelines was linked with a 20% decrease in mortality risk. Speaking about the findings of the study, Dr. Alpa V. Patel, Ph.D., strategic director of the Cancer Prevention Study-3 for the American Cancer Society (ACS), said: “Walking," she continued, "has been described as the 'perfect exercise' because it is simple, free, convenient, doesn't require any special equipment or training, and can be done at any age.” So, the next time you have a short journey to make and providing the weather is good and you’re feeling up to it, why not walk?

Just 60 seconds of jogging per day could boost women's bone health

20/07/2017

While many people think that getting fit involves hours spent in the gym each week, a new study suggests just one minute of jogging each day is enough to boost women’s bone health. Researchers found women who performed “high-intensity, weight-bearing activity” 60 to 120 seconds a day had 4% better bone health than those who didn’t. Furthermore, those that did slightly more exercise benefitted exponentially. For example, women who did more than two minutes had 6% better bone health. The researchers said that a slow jog for post-menopausal women and a medium-paced run for pre-menopausal women was enough to provide health boosts. Publishing their findings in the International Journal of Epidemiology, the researchers from the University of Exeter and the University of Leicester, both in the United Kingdom, said there was a clear link between exercise and bone health. For their study, the researchers used data obtained from wrist monitors worn by more than 2,500 women for a week. Osteoporosis is a disease that causes bone to become weak and brittle. While bone tissue is constantly broken down and replaced in healthy people, new bone production does not keep pace with the removal of old bone in individuals with osteoporosis. The National Osteoporosis Foundation estimates that there are around 54 million people living with osteoporosis and low bone mass in the United States alone.
