Exercise games can aid weight loss in overweight children

USA researchers have proven that video games such as Kinect Sports and Just Dance can help overweight children lose weight and improve their cardiovascular risk factors.

Adherence to the programme of one hour three times a week was very high with 94.4 % sticking to the games. 46 families were involved with 23 families in the intervention and control groups.

BMI , blood pressure, total cholesterol and LDL cholesterol all improved in the intervention group.

The study was funded by the AHA.

Retirees are happier when they are active

An Australian study has shown that getting a good sleep at night and being active during the day was the most effective way to boost mood in retirees.

105 people took part in the Life After Work study. They were followed for six month before retirement to 12 months afterwards. They carefully logged their activities and their mood was measured.

The time spent on chores, physical activity, quiet time, screen time, self care, sleep, transport and work, all changed over this period of time. The most favourable substitution was replacing work time with physical activity and sleep.  Replacing work with screen time and social activity showed less effect on mood enhancement.

After retirement, depression, anxiety and stress all reduced.

One Year of 10,000 Steps

I celebrated an anniversary earlier this month – one year of counting my steps every day. So, what has it taught me?

I’m very competitive – with myself. So, I have done at least 10,000 steps every day now for a year. I can’t bear to have a day where that doesn’t happen. I’ll get up early, if necessary, to walk.

I’m also boring about it. When I told my husband about the anniversary of doing those 10k steps, he said, “a year of hearing about it too”. My NY resolution is to stop going on about it.

A step counter does make you more active in general. If I’m doing housework, for example, I do it inefficiently. I don’t gather up all the stuff that needs to go upstairs or downstairs in one bundle. I take it up and down in a few trips. Going to the library, popping out for supplies from the shops, bringing in the bins…everything becomes an opportunity to add to the step count.

I’m a geek. The UP app is the one I use most on my phone. Have I done my steps yet? How does today compare to yesterday? What’s my average like for this week? The app also tracks your sleep, though that’s not quite as interesting.

You can use exercise instead of insulin. Proceed with caution here, my insulin-dependent friends. This is an individual thing that won’t work for everyone. But walks after lunch do the same job as insulin for me – sometimes.

Exercise won’t help you lose weight, but it will help you maintain. I’ve kept my weight consistent over the whole year, or at least I think it is as I don’t weigh myself. Everything in my wardrobe fits, though, and some of them date back more than ten years.

I feel better. Being active every day makes you feel TERRIFIC.

I’d definitely recommend one. I use the Jawbone Up, the basic model that costs about £5.99. I didn’t want a FitBit as they are much more expensive, and you need to charge them every five days, whereas my entry level tracker needs the battery replaced every two months. The Fitbit also seems invasive. I’m obsessive enough without something on my wrist bleeping at me if I haven’t moved for an hour or so.

Do you find exercise and activity helpful for the management of your diabetes?

BMJ: Regular, physical exercise is the miracle cure to ageing

Tai chi.jpg

Adapted from Scarlett McNally’s article in the BMJ 21 Oct 17

The NHS and social care are inextricably intertwined. The rising number of older people is frequently blamed. The rising social care costs in this age group can be modified however. NICE in 2015 said, “disability, dementia and frailty can be prevented or delayed”.
The need for relatives or paid carers arises when someone can no longer perform the activities of daily living such as washing, dressing and feeding themselves. For some people the ability to get to the toilet in time is the critical thing between having carers come to their own home twice a day and being admitted to a full time care facility.
The cost of care rises five times for those admitted to residential facilities. An average residential placement costs £32,600 a year and may be needed for months, years or decades.
A cultural change is needed so that people of all ages aspire to physical fitness as a way of maintaining independence into old age. There just doesn’t seem to be the local or national infrastructure to support this however.
Ageing is a normal, if unwelcome, biological process that leads to a decline in vision, hearing, skin elasticity, immune function and resilience, which is the ability to bounce back.
The decline in fitness with age starts around the age of 30 and accelerates after the age of 45. Things move downhill even faster if someone has a sedentary job that involves car driving and computer work. Diabetes, dementia, heart disease and some cancers become more common.
Some may think that fitness in old age is down to genes and luck but social strata differences exist with good nutrition and exercise as major factors in enhancing health and fitness into old age.
Apart from getting older, environment and lifestyle affect disease onset. At the age of 40, some forty percent of people have at least one long term condition and the rate goes up by ten percent each decade. As environmental and behavioural factors stack up over time, more people develop an increasing number of diagnoses. Yet, small habits such as cycling to work, can mitigate the effects of a sedentary job.
As time goes on, a person’s independence can be compromised by well -meaning carers and relatives doing more for their charges rather than letting them do things for themselves.
Genetics are thought to play only 20% of the part in the development of modern diseases. Lack of fitness has more of a part to play than disease and multiple morbidity.
Pain can lead people to limit their activity because they think it could make their illness worse, but strength, stamina, suppleness and balance training are usually needed more rather than less as you get older and accumulate illnesses.
These factors improve cognitive ability in midlife through to a person’s 80s. They can reduce the onset of dementia. Increasing independence results.
The Academy of Medical Royal Colleges go as far as describing exercise as “the miracle cure”. Improving the time to stand from sitting down, walking, and resistance training exercise all produce a dose response effect with the most frail benefitting the most. Any exercise or activity such as gardening that gets you slightly breathless and is done in ten minute bursts or longer counts as the 150 minutes minimum as recommended in the UK.
Stopping smoking and limiting alcohol are also worthwhile interventions. Gyms, walking groups, gardening, cooking clubs and volunteering have all been shown to improve the health and well- being of people of all ages with long term conditions.
When people are admitted to hospital they often experience a rapid decline in function. Patients are not allowed to move about or go to the toilet themselves in case they fall. The numbers of these are considered adverse incidents and are strongly discouraged. Thus the ambulant end up chair or bedbound. Most inpatients spend 80% of the time in bed and more than 60% come out with reduced mobility.
All patients should be encouraged to start an activity programme and gradually increase the frequency, intensity, and time that they do it.
The outdoor environment can be improved by even pavements, open spaces, tables and seating in public areas, safe cycle lanes and restriction in car use.
Money may need to be shifted from passive care and polypharmacy to activity and rehabilitation services.
People need to concentrate on being active every day. A quarter of women and a fifth of men do no activity whatsoever in a week never mind the minimum recommended 150 minutes a week.
In the UK the total social care bill is over £ 100 billion which is virtually the same as spent in the NHS.
The cost of care doubles between the ages of 65 and 75 and triples between 65 and 85. If everyone was just a bit fitter, the savings would add up.
Individuals need to see it as their responsibility to stay fit or improve their fitness. There needs to be more national coordination regarding the environment, transport and our working schedules so that we can all stay that bit functionally younger into old age. We could be making the difference between staying at home or depending on social and residential care.

World Diabetes Day

Today is World Diabetes Day – happy diabetes day to my fellow (and female) diabetics the world over. May your blood sugars be stable for today at least. No hypos or hypers are allowed…

Who knows what the next year will bring? There have been lots of exciting developments in the diabetes world over the last 12 months – from the first hybrid insulin delivery system to the NHS’s decision to offer flash glucose monitoring, to the identification of a new biochemical ‘signature’ as a potential early indicator of type 1 diabetes onset, we edge closer than ever before to understanding and properly managing this condition.

One piece of news I spotted recently that has implications for all of us (and is relatively easy to do) was research that has shown that people with type 1 diabetes who are more active have a lower risk of premature death than those who don’t exercise.

Diabetes.co.uk reported that the Helsinki study. It followed 2,639 people with type 1 diabetes, 310 of them had diabetic kidney disease. They were followed up eleven years later. During the course of the research, some 270 people diets. In the least active group, the death rate was 14.4 percent. Only 4.8 percent died in the group who performed more exercise. Activity seemed to benefit patients who had kidney disease and those who didn’t.

The lead study author, Der Heidi Tikkanen-Dolenc from the University of Helsinki and Helsinki University Hospital, said: “Doctors have always prescribed physical activity for their patients with type 1 diabetes without strong evidence. Now we can say that in patients with type 1 diabetes, physical activity not only reduces the risk of diabetic nephropathy and cardiovascular disease events but also premature mortality.”

Keeping active is a challenge in this day and age. Our governments and big business have unwittingly conspired to create a world where the default way to live is a sedentary one where cheap, nasty junk food is all-too-readily available. Being active and exercising often takes a lot of effort, unlike populations who lived years ago who were active because they had to be.

But the message that exercise can help prevent premature death IS a powerful one. Let’s celebrate World Diabetes Day with a walk!

Gretchen Reynolds: You are never too old to give up on exercise

cyclist robert marchand

At the age of 105, the French amateur cyclist and world-record holder Robert Marchand is more aerobically fit than most 50-year-olds — and appears to be getting even fitter as he ages, according to a revelatory new study of his physiology.

The study, which appeared in December in The Journal of Applied Physiology, may help to rewrite scientific expectations of how our bodies age and what is possible for any of us athletically, no matter how old we are.

Many people first heard of Mr. Marchand last month, when he set a world record in one-hour cycling, an event in which someone rides as many miles as possible on an indoor track in 60 minutes.

Mr. Marchand pedaled more than 14 miles, setting a global benchmark for cyclists age 105 and older. That classification had to be created specifically to accommodate him. No one his age previously had attempted the record.

She was particularly interested in Mr. Marchand’s workout program and whether altering it might augment his endurance and increase his speed.

Conventional wisdom in exercise science suggests that it is very difficult to significantly add to aerobic fitness after middle age. In general, VO2 max, a measure of how well our bodies can use oxygen and the most widely accepted scientific indicator of fitness, begins to decline after about age 50, even if we frequently exercise.

But Dr. Billat had found that if older athletes exercised intensely, they could increase their VO2 max. She had never tested this method on a centenarian, however.

But Mr. Marchand was amenable. A diminutive 5 feet in height and weighing about 115 pounds, he said he had not exercised regularly during most of his working life as a truck driver, gardener, firefighter and lumberjack. But since his retirement, he had begun cycling most days of the week, either on an indoor trainer or the roads near his home in suburban Paris.

Almost all of this mileage was completed at a relatively leisurely pace.

Dr. Billat upended that routine. But first, she and her colleagues brought Mr. Marchand into the university’s human performance lab.

They tested his VO2 max, heart rate and other aspects of cardiorespiratory fitness. All were healthy and well above average for someone of his age. He also required no medications.

He then went out and set the one-hour world record for people 100 years and older, covering about 14 miles.

Afterward, Dr. Billat had him begin a new training regimen. Under this program, about 80 percent of his weekly workouts were performed at an easy intensity, the equivalent of a 12 or less on a scale of 1 to 20, with 20 being almost unbearably strenuous according to Mr. Marchand’s judgment. He did not use a heart rate monitor.

The other 20 percent of his workouts were performed at a difficult intensity of 15 or above on the same scale. For these, he was instructed to increase his pedaling frequency to between 70 and 90 revolutions per minute, compared to about 60 r.p.m. during the easy rides. (A cycling computer supplied this information.) The rides rarely lasted more than an hour.

Mr. Marchand followed this program for two years. Then he attempted to best his own one-hour track world record.

First, however, Dr. Billat and her colleagues remeasured all of the physiological markers they had tested two years before.

Mr. Marchand’s VO2 max was now about 13 percent higher than it had been before, she found, and comparable to the aerobic capacity of a healthy, average 50-year-old. He also had added to his pedaling power, increasing that measure by nearly 40 percent.

Unsurprisingly, his cycling performance subsequently also improved considerably. During his ensuing world record attempt, he pedaled for almost 17 miles, about three miles farther than he had covered during his first, record-setting ride.

He was 103 years old.

These data strongly suggest that “we can improve VO2 max and performance at every age,” Dr. Billat says.

There are caveats, though. Mr. Marchand may be sui generis, with some lucky constellation of genes that have allowed him to live past 100 without debilities and to respond to training as robustly he does.

Lifestyle may also matter. Mr. Marchand is “very optimistic and sociable,” Dr. Billat says, “with many friends,” and numerous studies suggest that strong social ties are linked to a longer life. His diet is also simple, focusing on yogurt, soup, cheese, chicken and a glass of red wine at dinner.

But for those of us who hope to age well, his example is inspiring and, Dr. Billat says, still incomplete. Disappointed with last month’s record-setting ride, he believes that he can improve his mileage, she says, and may try again, perhaps when he is 106.
