Ask Well, answer Well

A client of mine passed along a link to a regular column on exercise in the New York Times.  It’s a Q&A page and the author of the blog, Gretchen Reynolds, gives, from what I’ve read so far, balanced and knowledgeable answers.  She does a good job of condensing the research into practical and meaningful advice to her readers.  So, I thought I’d point you to her column and then I would tackle one of the questions she addressed and offer anything else I feel could be of help.  So, let’s take a look at a condition one of Gretchen’s readers asked about–plantar fasciitis and what self treatment could be done to help heal it.  To read the full question and answer, see the following:  How can I facilitate healing my plantar fasciitis?  According to the doctor she interviewed for the article, self-care involved doing a calf stretch at the wall 20 times per leg and holding each stretch 10 seconds.

I would like to add to that a course of treatment advocated by a physiotherapist and author of “The 5-Minute Plantar Fasciitis Solution”, Jim Johnson.  He cites a number of studies into various types of stretching, sometimes in conjunction with other modalities such as anti-inflammatory drugs like Ibuprophen.  The treatment he prescribes is a specific type of stretching involving pulling back on the toes of the affected foot while that foot is crossed over your other thigh.  The stretch is held for 10 seconds and repeated 10 times.  The whole sequence is performed at least 3 times a day (10X10X3 = 300 seconds or 5 minutes).  Personally, I can vouch for the effectiveness of this stretch!  But please see his book for the full details.

Calf stretches were shown to be more effective in keeping plantar fasciitis from returning rather than treating it specifically, according to the studies he cites.  This classic stretch involves placing one foot forward on the floor, toes touching the wall, and the other leg well back and kept straight.  With the hands on the wall, lean in to the ball by bending the front knee.  Hold for 20 seconds per leg and do at least 3 times per day.  Repeat 3 days/week on alternate days.

The one pattern I noticed for all of the stretches suggested in the studies I’ve looked at were that the most effective stretches were held for several seconds (15-20 or performed multiple times if held for less time) and they were repeated several times a day and several days a week.  Clearly the body likes to “bounce back” to it’s familiar state and so not giving it too much time in between treatments to do so is what is required.  Unfortunately that familiar state is not always the most comfortable!

As with any health and fitness advice column, I recommend that you see a doctor or other qualified health care provider to get a proper diagnosis first before beginning self-treatment.  Depending on the condition, that treatment may be quite different.  What we often call an “-itis” may really be an “-osis” or the other way around.  Is the condition acute (a sudden traumatic event or injury and the first few days following), chronic (long-term with or without a known specfic cause or trauma), or sub-acute (a condition that resulted from a traumatic event lasting from several days to a few weeks)?  Other times we assume something is a tear when it really is “wear and tear”.  Sometimes we try to diagnose ourselves because we know someone else who had the same condition.  But was it really the same condition or did our friend’s perception of his/her symptoms just sound the same as ours.  Those are two very different questions.

So, my advice is to get the information you need to make an informed decision.  You may be afraid to see a physician, physiotherapist, or other health-care provider because you’re afraid that you may have to take medication or go for therapy, and that may consume too much of your time, money, or your quality of life.  But having a firm diagnosis does not necessarily mean that you need costly treatment or medication.  Many ailments like plantar fasciitis can be treated for free because you’re the one doing the work.  You may have somewhat better outcomes with an expensive therapeutic device such as laser or shock wave therapy but often these modalities provide the same outcome as self-care, although they may hasten or enhance the healing process.  How they will help and if they will help your condition depends on what your condition is.   Sometimes, you just need to take more time and be more patient with self-care.  But if you are limited by time or money or both and do not want to take medications, self-care such as a program of specific stretching tailored to your condition is often all you need, although heat or ice where and when appropriate may also be required.  Again, none of these treatments cost anything, although they do require some of your spare time.  However, sitting home doing a few minutes of stretching is not exactly wasting time compared to time lost travelling for professional treatment.

Conditions such as plantar fasciitis often recur because of imbalances or weaknesses in the underlying structures (the bones and joints themselves) or by improper movement patterns, which, unfortunately are exacerbated by the aging process.  And so it is imperative that you have a self-care treatment plan in your tool kit.  The type of stretching you choose, whether you use ice, heat, or both, or neither, lifestyle changes you may make, and other things you can do for yourself will depend on the specific condition you have.  Get a proper diagnosis and once you do have one, remember that you have options!

What Will You (Still) Be Doing at 102? Working Out, I hope!

Once in a while I read a feel-good story which I then like to pass on to  my readers.  This is a story from The Washington Post, link below.  Thought you might enjoy hearing about a 102 year-old gentleman who only started working out a few years ago!  He was physically active during his working life but over the years and especially after the loss of loved ones and loss of responsiblity, he felt he was getting lazy and decided to “take it up a notch”. He is a real inspiration on how important it is to be physically active or exercise regularly throughout the lifespan!

Happy New Year 2013!

iStock_000021323212_ExtraSmallHappy New Year 2013!
Make it your year to be “On the Move”

We hear more and more about the dangers of sedentary living, and sitting too long in particular.  Studies have linked sitting and sedentary lifestyles to a whole host of ailments, including higher risk of Type II Diabetes and shorter life expectancy.  The longer we sit, the less our muscles move, and the less fuel they require.  But we keep feeding them just the same, so that excess fuel (sugar) gets stored in our bloodstream instead of being burned for fuel.  Thus the link to diabetes and other health concerns that come with excess blood sugar and obesity.

But did you know that even if you exercise every day but the rest of your day is primarily sedentary, you can still suffer from many of the same ailments — in other words, thirty minutes to an hour a day of exercise does not undo the damage done by being inactive the rest of the time you are awake.

So, how did we get to be a culture that sits or is sedentary most of our day?  One might argue that we have no choice when we work in an office all day and have to commute, but I believe it’s the subtle changes that have occurred over the last thirty years that have made the problem worse.

Our commutes are longer — up to twice as long as even ten years ago in many North American cities.  In fact, my home city of Toronto has one of the longest average commute times in North America.

We’ve replaced a lot of our TV watching time with “on-line” watching time.  Twenty-five years ago, most of us who used a computer did so only at work.  Other than for playing PacMan, not many of us used a computer at home.  And if we did, we might have spent a few minutes working on the family budget.  Most of us were not “on-line”, so sitting time at home was primarily for watching TV or reading a good book.   When we did sit and watch TV, we had to get up to change the channel, turn up the volume, or fix the “vertical hold” (remember those days?).  And, most of us went to bed after the nightly news ended.  Today, apart from watching television, people sit in front of their computers for hours emailing, being on Facebook or Twitter, even bringing their laptops and tablets to bed.  On average, North Americans are sleeping one hour less per night.  That extra hour is not spent being phsyically active but instead is spent sitting or being sedentary.

Even at the office, we are moving far less than we did a generation ago.  Emailing colleagues down the hall is not uncommon.  Let’s face it, it gives us a “paper trail” but as a result, instead of getting up and going down the hall to talk to a colleague, we sit and do it all without having to leave our desk.

Most of us are working longer hours too.  The average office worker in North America is working a longer day since the 2008 recession.  So, even though the work day had been shorter than it was a century ago, it is steadily creeping back up.  The difference is that a century ago, we did not have the labour saving technology we do today, so people were more physically active…by necessity.

And this spills into our meal times too.  More and more we are relying on convenience foods for our dinners because we are so tired at the end of a long day at work, that we would rather open up a package of food instead of making it from scratch.  Go into any supermarket these days and there are whole aisles of prepared meals waiting to be picked up, taken home, heated, and served.  Voilá!  The act of cutting up vegetables and preparing dinner while standing (remember stirring a pot?) has been replaced by heat, serve, and eat.

So, when you add it all up, we are sitting for longer periods of time.  Coupled with serving sizes which have nearly doubled in the last twenty-five years, we are quite simply eating more and moving less.

What we really should be doing is eating less and moving more!

So, what to do?  It’s still early — make 2013 your year to do just that — eat less, move more!!

How to do it?  I wish I could wave a magic wand and make your commute shorter or subtract an hour from your long day at the office but I can’t.  However, I can offer some suggestions to help you eat less and move more.

1. If you must send an email to a nearby colleague, do so but get up from your seat and hand-deliver it to them.  Even better, save a tree and don’t print it.  Send it and make a point of still going to visit the colleague and asking if they require anything more or need clarification.  Or just tell them that you’re looking for an excuse to get up an “stretch your legs”.  You might even inspire them to do the same.

2. Stand up for part of your work day.  Do you need to sit and take that phone call?  Do you need to sit through all of the meeting?  Could you convince your colleagues to stand for part of it?  If it’s your meeting, you make the call!

3. Walk up stairs instead of taking the elevator as much as possible.  If you work on the 25th floor, if possible get off the elevator at the 23rd or 24th and walk the rest (assuming you don’t set off any alarms!).

4. Walk on your lunch hour.

5. If you go out for lunch with friends and colleagues, how about splitting an entree or skipping dessert?  We managed on fewer calories in the past quite fine, when the obesity rate was much lower (and coincidentally we moved more) so we can do it again!

6. If you need to run errands after work, look for a parking space far from the store entrance.  You avoid all the headache of jostling for the same spot that everyone else is, and you’ll get a few steps in.

7. Rely less on processed food even if you’re on a time crunch.  Processed foods are packed with extra sugar, salt, and refined flour, which pack on the pounds with extra calories, require fewer calories to be digested, and spike your blood sugar.  Convenience does not have to mean processed!  If you have to “pick something up” for dinner, how about making the prepared food only a part of your meal?  Buy some raw veggies or salad greens and prepare them yourself as a side dish.  Not only do they provide good fibre to your diet but you’ll need to stand a little longer at the counter before you plunk yourself down at the kitchen table or in front of the TV.

8.  Don’t forget to exercise!  Those thirty minutes to an hour of moderate-to-vigorous physical activity per day are still crucial to your health.  It works hand-in-hand with cutting down on the time you spend sitting.  Make sure your exercise regimen includes both muscle building AND aerobic (cardio or endurance) activites — and don’t forget to stretch!

9. Whether sitting at the office or at home, get up and move at least every hour.  It doesn’t mean you have to walk around a lot (although that’s not a bad idea).  At a minimum, just stand up, even if only for a few seconds.  It will give those muscles that you’ve been sitting on and holding in a flexed position a break.  They will get stretched just by standing up!

10.  Be aware of the time you spend on the computer at home and ask yourself, “how much of this time is quality time?”  Do I really need to post ten cute kitten photos every day on Facebook?  Quality over quantity is a good rule to follow.

So, it’s a new year!  How about making a resolution that you can keep quite easily — make it your year to be “on the move”!

Findings out of the Canadian Cardiovascular Congress 2012

The annual Canadian Cardiovascular Congress took place between October 26 and 31 in Toronto this year.  The Toronto Star covered the conference and a number of interesting findings appeared in press releases this past week.

Especially worth a read are how three prominent cardiologists keep their own hearts healthy.

What are the main things they do? It should come as no surprise when they say they…eat a healthy diet and exercise!

Some other interesting findings that were presented at the conference were the positive effects that  exercise had on cognitive function.

And one that I’m sure will garner debate on the pros and cons of the flu vaccine–how getting the flu shot may be good for your heart. 

Never Leave the Playground!

A colleague of mine sent me a link to a video of a gentleman in his early 70s who, some might say, has never grown up.  Besides putting a smile on your face, you will also be amazed at the agility, coordination, and balance of this man.  I don’t avise doing some of these stunts at home, folks, but after you’ve watched him you may just want to take up juggling at least.  He’s right about the connection between having an active body and an active mind–there’s plenty of research to back that up–and he truly is an inspiration for those of us who want to keep moving at any age.  Hope you enjoy. Here’s hoping we…

More on Falls

Last Wednesday The Lancet medical journal reported on the findings of  researchers who studied instances of falls in elderly people residing in 2 BC long-term care (LTC) facilities.  Videos were captured of 130 residents who had fallen to determine the circumstances around the fall.   Of the 227 falls captured on video, 41% were the result of improper weight shifting.  The rest of the falls were attributed to stumbling or tripping (21%), bumping into objects, losing support, and collapsing all tied at  11%, and 3% were a result of slipping.   Surprisingly, more falls were a result of weight transference than what was assumed.  Weight tranference is when the centre of mass is taken outside the base of support.  When we are standing still, our centre of mass is directly over our base of support.  When there is a disturbence in which the centre of mass oves moves outside the base of support, balance is challenged and if balance is lost, a fall can occur.  The researches concluded that by knowing better the circumstances around falls, balance and falls prevention programs can become more targeted and effective.

To your health!

Do More Reps Mean More Muscle?

The belief that more weight built more muscle than more repetitions did is being given a second consideration–at least in older men.

Researchers studied 2 groups of 6 young men (avg age 24) and 2 groups of 6 older men (avg age 70) who followed one of two exercise programs.  Half of the young and half of the older participants performed knee extensions using 3 sets of 14 repetitions then 6 sets of 14 repetitions at lower weight while the other half performed the same exercise using 3 sets of 8 repetitions then 6 sets of 8 repetitions at a higher weight.  The total muscle exertion was the same regardless of the number of sets and reps because when the weight was lower, the volume (sets and reps) was higher and vice versa.  Biopsies were taken of the participants’ leg muscles to look for the amount of protein synthesis (which occurs when muscle is being repaired and rebuilt after a work-out).   In the two groups of young men, the amount of muscle growth was not significantly increased when higher repetions or sets were involved, i.e. the higher weight played more of a role than the number of sets/reps.  This was not the case for the older men.  For those two groups, increasing the number of reps  had a greater effect on protein synthesis even when the weight was low.  From a safety standpoint, it is often recommended that older people benefit from lower weight and higher reps but now it may also be the case for muscle growth as well.

To your health!

Can Nordic Walking increase your strength and cardio fitness?

nordic walkingResearchers in Finland recently studied the effects Nordic walking (or “pole walking”) had on functional capacity in older adults. Functional capacity reflects one’s ability to perform activities of daily living independently. Typical measurements for functional capacity are strength, flexibility, balance, and cardiovascular fitness (or endurance). The study examined whether a Nordic walking program contributed to improvements in these measures as well as walking gait, which plays a vital role along with balance in reducing instances of falls. A compromised walking gait is strongly associated with falls.

Participants were divided into two groups: 23 people were placed in a Nordic walking group and 14 were placed in the control group, which was sedentary. Beyond their current level of physical activity, members of the control group were asked not to participate in any new physical activity for the duration of the 9-week program.

Nordic walking or pole walking is a form of exercise that is very popular in Scandinavian countries and in Finland. In recent years, it has been gaining ground in North America, especially amongst older adults. It is a safe form of cardiovascular exercise, especially for those who like to walk as their main fitness routine. It also has benefits for strength gains, especially in the upper body. It involves walking with a set of poles, much like one would use for cross-country skiing, only participants walk in urban areas– along bike and walking trails, sidewalks, and in some cases, hiking trails (with special tips).

Previous studies have shown increases in heart rate and oxygen uptake, both of which are important for maintaining independence and assisting with activities of daily living (ADL). Most of the previous studies, however, have focused on younger people (middle age) and those with chronic conditions that would be improved with stronger cardiovascular fitness. Studies of Nordic pole walking in older adults are limited, although a previous study (2007) showed Nordic walking to be an appropriate exercise method for older people because it has beneficial cardiovascular benefits. A study such as this is important if improvements are going to be made to the general older adult population’s activity levels. Since walking is the most common leisure-time physical activity chosen by older adults, Nordic pole walking may be such an enhancement that could boost those activity levels. Another purpose of the study was to determine the effects Nordic walking had on the participant’s gait. The researchers hypothesized that a 9-week Nordic walking exercise program would increase functional capacity and improve walking balance in older adults. It generally takes two months for enough physical changes from exercise to show up in a test.

The 37 participants were male and female age 65 and older and the two groups were controlled for equal portion gender and age. The participants were given fitness and gait assessments using a common battery of tests before and after the study’s conclusion, one that I frequently use with my clients, called the Seniors’ Fitness Test (Rickli and Jones, 2001).

The 9-week Nordic walking program consisted of twice weekly hour-long sessions, which included a 5 minute warm up (stretching and slow walking), 40 minutes of Nordic walking with 10-min stretching mid-point, followed by a 5 minute cool-down of slow walking and stretching. For the Nordic walking portion, the participants were instructed to walk as fast as comfortable. Training intensity was based on the participants’ rate of perceived exertion. Participants also wore heart rate monitors during the first exercise session and had a target heart goal of 60% of the age-predicted maximum. The warm up and cool-down consisted of walking at low speed (without the poles) and stretching with the poles. All 23 participants in the Nordic walking group completed the 9-week program although there were some absences during the training period.

At the end of the nine weeks, both groups were re-assessed using the same test battery. Improvements were made across all measures in the Nordic walking group. Hip and leg strength as measured by the Chair Stand Test increased on average by 15.3% in the Nordic walking group whereas there was only a 2.2% increase in the control (sedentary) group. Arm strength as measured by the Arm Curl Test increased on average 19.7% vs. 1.9% in the control group. Other measures of functionality all showed significantly greater increases compared with the control group. The 2-Minute Step Test, which assesses cardiovascular fitness showed an average increase of 14.0% in the Nordic walking group vs. a 2.5% increase in the control group, the “Sit-and-reach” test, which assesses thigh and calf flexibility, showed a 92.5% increase vs. 2.9% increase in the control group. It was thought that the stretching exercises during warm-up and cool-down played a large role in contributing to this large increase in leg flexibility. However, since Nordic walking assumes a large stride length compared to regular walking, the walking pattern itself may have also been a large contributor to the increased flexibility.

The Nordic walking group experienced on average a 17.3% increase in upper body flexibility as measured by the “Back Scratch Test” compared with a 23% DECREASE in the control group. When it came to assessments of balance related capacity, there was only a 10% increase in the Nordic walking group as measured by the “Timed Up and Go” Test (a measure of dynamic balance) but there was no change observed in the control group. However, the results of the gait analysis tests, which measured ground-reaction forces (GRF) and walking speed, were disappointing. They showed no change in either group. Researchers had hoped to find an improvement in gait as a result of the pole walking program but any falls reduction benefit resulting from muscular strength increases may have been countered by reliance on the poles themselves as balance aids.

There were some limitations in the study. Because of early drop-out in a third group (a regular walking group), there were insufficient numbers to study them separately so they were combined with the Nordic walking group. Thus the test group was much larger than the control group (23 vs. 14). It also means that comparisons between the test group and the control group do not necessarily suggest that improvements were a result of Nordic walking in particular or regular walking in general which caused the greatest change. However, Nordic walking does require engagement of upper and lower body muscles that is not required with regular walking. As well, previous studies which compared Nordic walking with regular walking showed an increase in cardiovascular function, although these were done with a younger population. So there is no reason not to credit a portion of the cardiovascular increase to the Nordic walking program specifically. The cardiovascular benefits may have been the result of strength increases in upper body muscles, which improve lung functional capacity, circulation, and oxygen uptake, the researchers said.

Although no significant improvements in gait were corroborated by the exercise program, muscular strength, flexibility, cardiovascular capacity, and to an extent dynamic balance were all improved in the Nordic walking group after the 9-week program. It is safe to say that based on this study Nordic walking is a useful tool in an activity tool kit to keep vital and strong as one ages. Perhaps it is an exercise you’ll pick up and enjoy. It’s worth a try!

To your health,

Chris

I’d be a lot healthier if I only had the time!

clockA recent survey from the Heart & Stroke Foundation (HSFC) reported that a large number of Canadians say they do not have time to exercise regularly or eat healthy foods, both strong tools in the prevention of heart disease and stroke.

According to the survey, eighty percent of Canadians know that heart disease and stroke can largely be prevented, postponed, and even treated by living a healthier lifestyle and 75% say they would live a healthier life if it weren’t for a number of barriers. The biggest barrier cited is time.

According to the HSFC report, for some of these barriers, it may be more a matter of perception than reality. Let’s take a look at what they had to say:

No time because of a long commute: This is a tough one as it is well-known that commute times have grown longer over the years and this is especially the case in Canada’s large urban centres. However, commute times are often half as long in smaller cities and towns and yet those residents are not necessarily any more active. In fact obesity rates are higher in Canada’s smaller towns and rural areas, on average, than in the big cities.

No time because of family obligations: Driving the kids to soccer practice and piano lessons, taking care of a loved one, visiting aging parents, school involvement, helping kids with homework. These things all take time and are all a part of busy modern life. But let’s not forget some of the modern conveniences that have freed up time. For many, the internet has allowed them to shop and do banking online, stay in touch with friends and family through email and Facebook, get help with homework or research a paper, and a whole host of other activities that used to take much longer when one had to get up and go somewhere. And yet, spare time still seems to be a rare commodity, keeping us from doing things that will help prevent heart disease and stroke. So where is that time going if it’s not spent exercising or cooking a heart-healthy meal? HSFC cites Statistics Canada in reporting that about 30% of Canadian adults spend 2 or more hours a day watching television with half those people reporting they spend over 20 hours a week in front of the box. And what about that other box? 15% of Canadian adults report spending 90 minutes or more each day in front of their computers–and that’s not during work time!

So, clearly extra time is there for many of us. We just have to make healthy eating and physical activity priorities in our lives.

Some other barriers cited in the survey:

Lack of facilities: 25 % of the respondents to the HSFC survey cited this as a barrier.

Cost of exercise programs, too, was a factor cited.

But in both these cases, one doesn’t necessarily need access to a gym or community centre to be active. As long as there are well-maintained parks and safe streets to walk, many Canadians can take advantage of the cheapest form of exercise–a brisk walk or hike! Walking briskly can get your heart and lungs working more efficiently so that you reap the benefits–major benefits in the fight against heart disease and stroke!

Cost of healthy food: Income and location are major factors for many Canadians who would otherwise shop for better food to cook. This is a real problem for low-income Canadians who can not afford fresh fruits and vegetables and many Canadians live in areas where access to such food is limited. The HFSC urges government, industry, and non-governmental organizations to increase access to healthy food for Canadians who can not afford it or who do not live close to sources of healthy food.

Lack of motivation: Half of the HSFC survey respondents say they lack the motivation to be more active or eat healthier food. HSFC reminds us that even small steps count and suggests some practical things that can be done, such as meal planning, having some quick and easy healthy food in your cupboard, and making meals in advance on weekends. As for exercise, get out with a friend for a walk. As they say, “you don’t need to run a marathon–but you do have to get off the couch”.

For more on the HSFC survey and to learn more about their initiatives, see their new campaign at heartandstroke.ca/time. The Foundation has set an ambitious goal of reducing death from heart disease and stroke by 25% by 2020. Clearly Canadians get the message that heart disease and stroke can largely be prevented or at least assisted through diet and exercise. They just need help to find the time to do so.

To your health,

Chris

How Much Exercise Do You Need?

In the most recent issue of the British medical journal, The Lancet, a study of over 400,000 people in Taiwan followed for an average of eight years has shown that you don’t need to exercise a lot in order to reap the benefits — including a longer life. As little as 15 minutes of exercise a day or 90 minutes a week can add up to 3 years to your life! Men in the study lived on average 2.55 years longer than their non-exercising counterparts and for women, there was 3.10 years on average between the active and the sedentary group. This translates to a decrease in overall risk of dying by 14% with as little as 15 minutes of exercise a day with a further reduction of 4% for every additional 15 min of daily exercise beyond the minimum amount of 15 min a day.

What type of exercise and what level of intensity?

Researchers examined different types of exercise from regular walking to fast walking to jogging to running and found the benefits were there at all levels but they did confirm that there is a dose-response relationship, so that those who exercised for longer periods and at a higher intensity level reaped more benefits. Again, the participants in the study were compared with people who did no exercise at all. What this study shows is that there are benefits at even 90 minutes a week (6 days X 15 minutes), which is less than Canada’s new guidelines of 150 minutes a week at a moderate level or above. However, the study also showed that those who met the generally recommended guidelines of 30 minutes per day at a moderate level, life expectancy was even greater (4.21 years longer for men, on average, and 3.67 years longer for women).

To your health,
