As little as 4,500 steps a day can have health benefits for older women

A new study at Harvard University concludes that for older women, walking as few as 4,500 steps a day reduced mortality compared with those who took only 2,700 steps a day.

Any movement, whether or not it counts as exercise, may help to extend people’s lives. People who are active have lower incidences of heart disease, obesity, and Type 2 diabetes and usually live longer than people who are sedentary. However, confusion remains about how much exercise we need and how intense it should be. Past research suggests meeting or even exceeding a 10,000-step-a-day goal. Mobile applications and fitness trackers have 10,000-step-a-day exercise goals built into them. The Canadian Physical Activity Guideline for adults 18-64 years is 150 minutes of moderate-to-vigorous aerobic physical activity per week, in bouts of 10 minutes or more.

In an interview with New York Times, I-Min Lee, a professor of medicine at Harvard University, who led the study, said: “People may not intuitively grasp what 150 minutes a week of exercise means in practical terms. Step counts are simpler, more concrete and convenient measure of physical activity. We can understand the concept of a step and how to add them up.”

Dr. Lee and her team looked at data from the Women’s Health Study, which has been tracking the health and habits of older women for decades. In that study, thousands of older women worn sophisticated activity monitor for a week. The monitors tracked the steps each woman took per minute throughout the day (but without showing any readouts of the totals, so the women would not know or respond to the counts).

Dr. Lee and her team gathered the step-count and health data from almost 17,000 of the participants, most of them in their 70s, and none of whom reported poor health. They also checked death records for the subsequent four to five years and than compared step counts and mortality. The team found that the women who had moved the least, taking only about 2,700 steps a day, were the most likely to have died during the follow-up period. Women who moved more often had considerably less risk of premature death, up to 7,500 steps a day. The threshold for reducing the risk of premature death was about 4,500 steps a day. Thos who reached 4,500 steps were 40 per cent less likely to have died during the follow-up period.

In terms of intensity, majority of the women strolled, rather than rushed; only a few walked intensively and for exercise. In this study, only the number of steps per day was associated with mortality, not the speed with which the women accumulated them.

This study looked at older women and mortality – further research is required to see if the findings apply to men or younger people. Dr. Lee concluded: “Even so, the findings suggest that step counts can be a useful way to measure exercise and that taking more steps is better than taking fewer.”

Walking sports, a trending phenomenon in Bristol, UK

Throughout the month of May, the Bristol Walk Fest is taking place in Bristol, United Kingdom. The festival is a celebration of walking. The walks are categorized into different themes:

  • Art and creative walks
  • Health and wellbeing walks
  • Nature and wildlife walks
  • Green and clean walks
  • History and architecture
  • Walking sport

In addition, the walks are graded to these levels:

  • Easy – mainly flat on paved surfaces without features such as steps; gentle pace.
  • Fairly easy – mainly flat on paved surfaces with features such as steps, gentle pace.
  • Moderate – more challenging slopes and the ground may be varied, may include steps and stiles; moderate pace.
  • Challenging – suitable for experienced walkers able to walk long distances over mixed terrain and gradients. Likely to include stiles; brisk pace.

Walking sports include Nordic walking, walking cricket, walking tennis, walking hockey, walking rugby, walking football, walking netball, walking Boccia, New Age Kurling and walking multi-sport. Bristol Walk Fest co-ordinator Kerry Morgan explained: “One of the joys of this year’s Walk Fest programme is the number of opportunities it gives for sports fans of all ages and fitness levels to try a walking sport. There’s a myth that these slower versions of popular sports are strictly for older people. While it’s true that they are a great way for ageing players to maintain their interest in a game, stay active and enjoy team camaraderie, they are also a way for lapsed and injured players of all ages to get back into their favourite sport.”

Walking sport is non-competitive and can be enjoyed by people of all standards and ages. Kerry continued: “The walking part is a physical leveller, and allows different abilities to play together, and grandparents, and parents with their children, competing together or against each other. Also, the fact its slower can also allow regular players to hone and practice their technique. So there really is not limits to it.”

Nordic walking and various walking tours and clubs are available in Canada; however, walking sports are still a rarity. Are you aware of walking sports happening in your area? Let us know at feedback@jointhealth.org.

High-intensity interval walk training associated with decreased disease activity in rheumatoid arthritis

A recent study has shown exciting new benefits associated with exercise for people living with rheumatoid arthritis (RA).

Rheumatoid arthritis is an autoimmune disease with hallmark symptoms of inflammation and resulting pain. It is a disease process (like cancer or diabetes) where the body’s immune system mistakenly attacks its own healthy joints. It is a relatively common disease – approximately 300,000 or 1 in 100 Canadians get it – and is often devastating to a person’s body if not treated properly.

Researchers at Duke University in North Carolina found that 10 weeks of high-intensity interval walk training was associated with decreased disease activity and improved immune function for adults with RA. High-intensity interval walk training refers to a popular form of exercise that includes short bursts of fast-paced walking at maximum effort followed by less intense recovery periods.

The study included twelve physically inactive adults over the age of 55, with a confirmed diagnosis of RA. Participants completed a 10-week program consisting of 3x 30-minute sessions a week of supervised treadmill walking. This Included a 5-minute warm up and 5-minute cool down. Within the training session, participants walked at 80-90% of their maximum effort in intervals of 60 to 90 seconds. These high-intensity intervals were followed by recovery intervals at 50-60% maximum effort. Speed and interval times varied for each person based on a cardiorespitory fitness test, but none exceeded walking pace. 

Disease activity was assessed by a rheumatologist through a count of swollen and tender joints, perceived general health and blood tests to measure inflammation. Cardiovascular fitness and immune functions were assessed using a variety of clinical and laboratory tests, as well as standardized questionnaires. At the end of the 10 weeks, the following outcomes were observed:

  • RA disease activity reduced by 38%, with a significant decrease in swollen joints, erythrocyte sedimentation rate (ESR) and improved self-perceived health. An ESR blood test measures the rate at which red blood cells settle in the period of one hour, revealing inflammatory activity in the body. 
  • Improved immune functions suggesting a reduced infection risk and inflammatory potential 
  • Cardiorespitory fitness increased by 9%
  • Resting blood pressure and heart rate both reduced 

 There is a substantial amount of research on exercise and rheumatoid arthritis, but few studies have reported the actual lowering of disease activity scores. As stated by the researchers, this study suggests that,

“High intensity interval walking could be an efficient, tolerable, and highly effective intervention to augment disease activity and improve overall health in patients with RA.”

There are certain limitations to the study such as the small sample size and no control group, but the findings will hopefully encourage more research in the area. In addition, these findings add to a growing body of research on the benefits of exercise for people with arthritis. To learn more about the study, click here.
