April 26, 2024 - Climb stairs to live longer - European Society of Cardiology 
"Compared with not climbing stairs, stair climbing was associated with a 24% reduced risk of dying from any cause and a 39% lower likelihood of dying from cardiovascular disease. Stair climbing was also linked with a reduced risk of cardiovascular disease including heart attack, heart failure and stroke."

April 24, 2024 - Low intensity exercise linked to reduced depression - Anglia Ruskin University, UK
"The analysis, published in the journal Neuroscience and Biobehavioural Reviews, found that physical activity reduced the risk of depression by 23% and anxiety by 26%. A particularly strong association was found between low and moderate physical activity, which included activities such as gardening, golf and walking, and reduced risk of depression. However, this was not strongly observed for high intensity exercise."

Jan. 17, 2024 - New research finds half-cardio, half-strength training reduces cardiovascular disease risks - Iowa State Univ.
"Their results, published in European Heart Journal, indicate that splitting the recommended amount of physical activity between aerobic and resistance exercise reduces cardiovascular disease risks as much as aerobic-only regimens. Resistance exercise on its own for the same amount of time did not provide the same heart health benefits when compared to the control group."

Jan. 15, 2024 - Impacts during everyday physical activity can slow bone loss - University of Jyväskylä, Finland
”A study conducted at the University of Jyväskylä, Finland, found that the bone mineral density at the femoral neck decreased, but the structural properties were maintained or even slightly improved during a year-long multicomponent exercise training intervention in 70- to 85-year-old men and women who had previously been physically inactive. Those who had accumulated more moderate and high-intensity activity did not experience as much deterioration in bone density as those who were less active or accumulated their daily activity at a lower intensity.”

Nov. 23, 2023 - 20 minutes of exercise can boost your brain after a bad night’s sleep - University of Portsmouth, UK
Sleep is fundamental in maintaining a healthy lifestyle, with adults recommended between seven and nine hours a night. However, recent reviews indicate that 40 per cent of the global population don’t get enough.
Consequences of chronic sleep deprivation include cardiovascular disease, obesity, neurodegenerative disorders, and depression. In the short term, a lack of sleep can reduce cognitive performance (CP), which takes a toll on your attention span, judgement, and emotional state.
A study, led by the University of Portsmouth, has found cognitive performance improves during a bout of moderate intensity exercise, regardless of a person’s sleep status or oxygen levels."

Sept. 28, 2023 - Walking more than five flights of stairs a day can cut risk of heart disease by 20%, study says - Tulane University
”Forget walking 10,000 steps a day. Taking at least 50 steps up the stairs each day could significantly slash your risk of heart disease, according to a new study from Tulane University. The research, published in Atherosclerosis, found that climbing more than five flights of stairs daily could reduce the risk of cardiovascular disease by 20%.”

Sept. 26, 2023 - Increasing Steps by 3,000 Per Day Can Lower Blood Pressure in Older Adults - University of Connecticut
”The study focused on a group of sedentary older adults between ages 68 and 78 who walked an average of about 4,000 steps per day before the study. After consulting existing studies, Lee determined that 3,000 steps would be a reasonable goal. This would also put most participants at 7,000 daily steps, in line with the American College of Sports Medicine’s recommendation.” Researchers found “On average, participants’ systolic and diastolic blood pressure decreased by an average of seven and four points, respectively, after the intervention.”

July 28, 2023 - Short bursts of daily activity linked to reduced cancer risk - University of Sydney
”As few as four to five minutes of vigorous intermittent lifestyle physical activity or ‘VILPA’ was associated with a substantially lower cancer risk compared to those who undertook no VILPA.” VILPA “… includes activities like vigorous housework, carrying heavy shopping around the grocery store, bursts of power walking or playing high-energy games with the kids.”

May 17, 2023 - CAN EXERCISE LOWER THE RISK OF DEVELOPING PARKINSON’S DISEASE? - AMERICAN ACADEMY OF NEUROLOGY
”Getting regular exercise such as cycling, walking, gardening, cleaning and participating in sports may decrease the risk of developing Parkinson’s disease, according to new research published in the May 17, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found female participants who exercised the most had a 25% lower rate of Parkinson’s disease when compared to those who exercised the least. The study does not prove that exercise lowers the risk of developing Parkinson’s disease. It only shows an association.”

February 28, 2023 - Daily 11 minute brisk walk enough to reduce risk of early death - University of Cambridge, UK
In a study published in the British Journal of Sports Medicine, researchers found 11 minutes a day of moderate-intensity physical activity would be sufficient to lower the risk of diseases such as heart disease, stroke and a number of cancers. “If you are someone who finds the idea of 150 minutes of moderate-intensity physical activity a week a bit daunting, then our findings should be good news."

February 24, 2023 - Exercise more effective than medicines to manage mental health - University of South Australia
"University of South Australia researchers are calling for exercise to be a mainstay approach for managing depression as a new study shows that physical activity is 1.5 times more effective than counselling or the leading medications."

February 6, 2023 - Playing golf may be just as healthy or better than Nordic walking for older people - University if Eastern Finland
"Researchers at the University of Eastern Finland investigated the immediate physiological cardiovascular effects of playing a round of golf, walking, and Nordic walking. All three types of exercise lowered blood pressure. A round of golf was lower in intensity but longer-lasting and more energy-consuming than walking or Nordic walking, thus showing positive effects on lipid profile and glucose metabolism."

Dec. 8, 2022 - Adding yoga to regular exercise improves cardiovascular health and wellbeing - Canadian Journal of Cardiology
"A three-month pilot study of patients with hypertension appearing in the Canadian Journal of Cardiology, published by Elsevier, demonstrates that adding yoga to a regular exercise training regimen supports cardiovascular health and wellbeing and is more effective than stretching exercises. Incorporation of yoga reduced systolic blood pressure and resting heart rate and improved 10-year cardiovascular risk."

Oct. 27, 2022 - Short bursts of vigorous activity linked with increased longevity - European Society of Cardiology
“The results indicate that accumulating vigorous activity in short bouts across the week can help us live longer,” said study author Dr. Matthew N. Ahmadi of the University of Sydney, Australia. “Given that lack of time is the most commonly reported barrier to regular physical activity, accruing small amounts sporadically during the day may be a particularly attractive option for busy people.” Among some of the study findings, researchers found "Regarding frequency, accumulating short bouts (up to two minutes) of vigorous activity on average four times a day was associated with a 27% lower risk of death. But health benefits were observed at even lower frequencies: 10 short bouts a week was associated with 16% and 17% lower risks of cardiovascular disease and cancer, respectively."

Oct. 20, 2022 - Activity 'snacks’ following meals may help maintain muscle mass: Study - University of Toronto
”Interrupting prolonged sitting with periodic activity “snacks” may help maintain muscle mass and quality, according to a new study by researchers at the University of Toronto. Daniel Moore, an associate professor of muscle physiology at the Faculty of Kinesiology & Physical Eduction (KPE) who led the study, found that short bouts of activity, such as two minutes of walking or body weight sit-to-stand squats, allow the body to use more amino acids from meals to build muscle proteins.”

August 24, 202 - Physical Activity May Have a Stronger Role than Genes in Longevity - University of California San Diego
"Our study showed that, even if you aren’t likely to live long based on your genes, you can still extend your lifespan by engaging in positive lifestyle behaviors such as regular exercise and sitting less," said senior author Aladdin H. Shadyab, Ph.D., assistant professor at the Herbert Wertheim School of Public Health and Human Longevity Science at UC San Diego. “Conversely, even if your genes predispose you to a long life, remaining physically active is still important to achieve longevity.”

August 15, 2022 - Exercise answer: Research shows it’s how often you do it, not how much - Edith Cowan University
Three groups of study participants performed bicep contractions and changes in muscle strength and muscle thickness were measured and compared. One group did six contractions a day for five days a week (6x5 group), another group crammed 30 contractions into a single day, once a week, and the third group performed six contractions just one day a week. Researchers found after four weeks, both the group doing 30 contractions in a single day and the group doing six contractions once a week did not show any increase in muscle strength. However, the 6x5 group saw significant increases in muscle strength at more than 10 per cent.

July 25, 2022 - Getting more exercise than guidelines suggest may further lower death risk - American Heart Association journal Circulation
”The American Heart Association recommends adults get at least 150 minutes per week of moderate-intensity aerobic exercise, 75 minutes per week of vigorous aerobic exercise, or a combination of both. That advice is based on federal guidelines for physical activity.” Researchers found “Going above and beyond the recommended minimums reaped greater longevity rewards, especially for moderate physical activity.” Extra moderate-intensity exercise for 300 to 600 minutes per week was associated with a 26%-31% lower risk of death from any cause…” compared to those who hit just the minimum goals for moderate physical activity, which had a lower risk of 20%-21%.

June 15, 2022 - Nordic walking improves functional capacity in people with heart disease - University of Ottawa Heart Institute

March 2, 2022 - META-ANALYSIS OF 15 STUDIES REPORTS NEW FINDINGS ON HOW MANY DAILY WALKING STEPS NEEDED FOR LONGEVITY BENEFIT - University of Massachusetts Amherst
According to researchers, for "... adults 60 and older, the risk of premature death leveled off at about 6,000-8,000 steps per day, meaning that more steps than that provided no additional benefit for longevity. Adults younger than 60 saw the risk of premature death stabilize at about 8,000-10,000 steps per day."

Feb. 28, 2022 - 30-60 mins of weekly muscle strengthening activity linked to 10-20% lower death risk - British Journal of Sports Medicine
"Between 30 and 60 minutes of muscle strengthening activity every week is linked to a 10-20% lower risk of death from all causes, and from cardiovascular disease, diabetes, and cancer, in particular, finds a pooled data analysis of the available evidence, published online in the British Journal of Sports Medicine.
The findings are independent of aerobic exercise. But the analysis points to a J-shaped curve for most outcomes, with no conclusive evidence that more than an hour a week of muscle strengthening activity reduces the risk further still."

Feb. 27, 2022 - PHYSICAL FITNESS LINKED TO LOWER RISK OF ALZHEIMER’S DISEASE - American Academy of Neurology
"The participants were divided into five groups, from least fit to most fit. Fitness levels were determined by how well participants did on a treadmill test. This test measures exercise capacity, the highest amount of physical exertion a person can sustain. For people who are middle-aged and older, the highest level of fitness can be achieved by walking briskly most days of the week, for two and a half hours or more per week." According to researchers "... they found that the people in the most fit group were 33% less likely to develop Alzheimer’s disease than those in the least fit group. The second most fit group was 26% less likely to develop the disease, while the middle group was 20% less likely and those in the second least fit group were 13% less likely to develop the disease than those in the least fit group."

Feb. 3, 2022 - Exercise can provide relief for dry, itchy eyes - University of Waterloo

Oct. 14, 2021 - Data Continues to Show that Americans Need at Least 5 Hours Per Week of Physical Activity to Prevent Some Cancers - American Cancer Society
”A new report finds more than 46,000 cancer cases annually in the United States could be prevented if Americans met the 5 hours per week of moderate-intensity recommended physical activity guidelines.” The Study found “… when focusing on specific cancer sites, 16.9% of stomach cancers, 11.9% of endometrial cancers, 11.0% of kidney cancers, 9.3% of colon cancers, 8.1% of esophageal cancers, 6.5% of female breast cancers, and 3.9% of urinary bladder cancers were associated with lack of exercise.”

April 1, 2021 - Keep pace: Walking with a partner is great but might slow you down - Purdue University
"The study looked at walking times and gait speeds of 141 individuals from 72 couples. The participants ranged from age 25-79 and were in numerous settings, including clear or obstacle-filled pathways, walking together, walking together holding hands and walking individually." Researchers were hoping to find that slower partners would speed up to match the faster partner, but that is not what the study revealed. According to Purdue Professor Libby Richards, “If someone substantially slows down when they are walking with someone else, that could negate some of the health benefits recognized if they walked alone at a faster pace,…” The message here remember if you walk with you partner, remember to keep up the pace!

Nov. 16, 2020 - Bursts of exercise can lead to significant improvements in indicators of metabolic health

In this Study conducted in Norway, which consisted of "... 1,567 participants, 400 were assigned to two weekly sessions of high intensity interval training (HIIT), 387 were assigned to moderate intensity continuous training (MICT), and 780 to follow the Norwegian guidelines for physical activity (control group), all for five years. " The researchers found no difference in all-cause mortality, no differences in cardiovascular disease, and no differences in cancer between the control group and the combined HIIT and MICT groups.

March 31, 2020 - Number of steps per day more important than step intensity
"Compared with people who took 4,000 steps a day, those who took 8,000 steps a day at the start of the study had a 50% lower risk of dying from any cause during follow-up. People who took 12,000 steps a day had a 65% lower risk of dying than those who took only 4,000.
Higher step counts were also associated with lower rates of death from heart disease and cancer. These benefits were consistent across age, sex, and race groups. Step intensity did not seem to impact the risk of mortality once the total number of steps per day was considered. Only an increased number of steps per day was associated with a reduced risk of death."

Feb. 3, 2020 - Aerobic Exercise Training Linked to Enhanced Brain Function in Adults at Risk for Alzheimer’s Disease
