10,000 steps

We have recently been working on a CPA initiative that has us monitoring our steps per day and making up the difference by walking or running.

For the average person 10000 steps wouldbe a good minimum.

It works out to 8 - 10 km per day depending on your stride.

For kayakers and swimmers,of course you have to convert - in the pool I am looking at trying 1000-2000m to add to the total. Kayakers have to use their GPSs to log on their mileage.

Whatever you do log it on to your exercise training plan.

Here is a useful section from the CPA website:


Why do physiotherapists recommend walking 10,000 steps per day?

Walking is a healthy weight-bearing exercise that can provide a total body workout. Walking, skating, blading and other cardiovascular activities help fight obesity, heart disease, arthritis and osteoporosis.

How do you know if you’re doing enough? One way to monitor your activity level is to wear a pedometer that counts the number of steps you take in a day. 10,000 steps per day is the ‘magic number’ recommended to achieve an active lifestyle.

By setting a daily step goal that builds up to 10,000 steps a day, you will realize a significant decrease in body mass index and blood pressure. Put your best foot forward today!

Getting started

1. How active are you?

Lifestyle Index Sedentary Low Active Somewhat Active Highly Active
Steps/day* <5000 5000 – 7500 7500 – 10,000 >10,000

* The above recommendations are for healthy adults. Children and youth require more steps/day. Elderly and disabled persons require less steps/day.

2. Aim for 10,000 steps/day

Research shows that taking 10,000 steps/day will have health benefits.* If you're walking at a brisk pace, 10,000 steps is about a 30 to 60 minute walk! This advice fits with Canadian Physical Activity Guide recommendations to accumulate at least 30 to 60 minutes of activity most days of the week.

From your current activity level, aim to reach 10,000 steps/day over a 6 week period by adding 500 steps every 2 weeks. If you’re already highly active, keep it up and consider increasing your steps for greater fitness capacity.

A few examples of activity step equivalents are listed below:

Cycling at 5 mph =50 steps/minute
Cycling at 15 mph =150 steps/minute
Slow steady swim =100 steps/minute

3. Measure your progress

Record your daily steps to track your progress. Research shows that keeping an activity log results in increased steps taken per day and commitment to reaching and maintaining your goal over a long period.

Steps added = Calories burned!

Steps Per Day Calories Burned Per Day
2100 100
8400 400
10,000 476

Hypothermia
















Two presentations were made last night at one of our regular association meetings related to Hypothermia. Information and knowledge on a range of topics like these always provides for a good discussion and ultimately allow us to better make decisions on the water. I was particularly intrigued by the concept of Cold Shock.

Prior debates on the risks inherent in paddling pale in comparison to the overall risk as described by the experts. As one presenter (an expert in cold water survival) reminded us - once you start paddling in water 60F or lower, you enter the danger zone.

Part of the discussion centred on training and acclimitization to cold water. Apparently you can do it.

A few highlights:
1. recognition of a problem > yourself or others in your group, be on the look out for the UMBLES - stumbles, mumbles, fumbles; these are manifestations of a problem with muscle or nerve function.
2. body temperature less than 35 degrees celsius, start action look to going to a hospital.
3. rewarming - handle gently at all times; discussion in the group made us rethink how well we are prepared as a group for initiating treatment if needed. the group should have at least one of everything needed - sleeping bag,tarp...
4. after drop - once assisted and helped, it is not over
5. not dead until warm and dead

Common exercises and machines to avoid

Individuals often come to the clinic and describe what they see and are instructed to use as exercise training techniques. Occasionally the design of some machines can be quite stressful, particularly to the spine.

There are a number that I would classify as higher risk. Which means basically that the exercises might be more irritating than beneficial. Exercise training of any sort, can no doubt aggravate - muscle stress, overuse, tendon inflammation. Beyond this, some types of training should be avoided or techniques modified. For most of us, the focus should be on endurance not generating high forces by moving large amounts of weight. This is particularly true regarding the lumbar spine. Ensuring there is a balance between abdominal work and extensor muscle work is critical.

Many active participants in a variety of sports do quite a few sports activities and never have any problems but, the movements are potentially stressful nevertheless. One should not make the assumption that because you always did a certain exercise and never had a problem, that the exercise was or is stiil safe. It could be you were just lucky.

Here are a few exercises to be careful doing and you may consider avoiding them all together:

Lat pull - if you are going to use the bar and machine pull the bar to your chest. Avoid bringing the bar behind your neck.



If the bar is pulled behind the neck, which is still common, the cervical spine can be excessively forced into flexion.












Good alternative









Others to keep in mind:

Military press - for some reason this is a very common part of circuits given to a wide range of participants in a number of gyms. The difficulty is that the average person places a substantial amount of compression through the lumbar spine. If your goal is to help reduce your back pain by becoming more active and fit - avoid this one. If you like to use free weights, use them individually and raise arm into forward flexion but keep the back well aligned.


Toe touches - the sun salutation uses a variation of this called the forward bend, but if you think you may have disc irritation or this is a completely new movement/exercise - pass over this part of the sequence. If you are attached to this movement, at least bend your knees and hips to reduce some of the stress. As a general rule be extra cautious in the morning, since this is the time the discs are fully rexpanded, after lying all night and the pressure of standing has been removed. This would seem contradictory to the yoga concept of doing the sun salutation early in the morning. Keep in mind the traditional yoga practitioners were Indians who, up until recently were not plagued with disc problems like us in the west. If you wish to do the sun salutation with the sun - get up an hour early and let the disc pressures normalize at least partially. Substitute with a few tai chi moves - forward step or side lunge.


Abdominals - While on your back practicing mini crunches or lying on the ball don't place the hands behind the neck; if you are weak in the abdominals you will inadvertently place a lot of force on the cervical spine soft tissues including the disc joint complex. Consider keeping the neck supported, in line with the chest. Aim to bring upper chest, head and neck all off the floor at the same time. Only enough to put a small bit of space between shoulder blade and floor. Another alternative, keep the neck supported and tighten the abdominals by moving the hips/knees, like a bicycle.

Sport and risk















This week we had an interesting discussion within our kayaking association. It centred on the possibility we might be unwittingly promoting risk taking behaviour by publishing photos that depicted kayakers close to icebergs. I think some of my shots and others, may have led to a review and subsequent club disclaimers. There were some who felt the association should not publish any photos of kayakers who appear to be near icebergs.
This recent debate caused me to reflect on my own photo taking - was the risk too great?
I didn't think so at the time. And I don't think so now.
An interview I heard some time ago suggested risk taking sports served a positive sociocultural good. Examples included horseback riding, motorcycle riding, scuba diving, and judo. The expert didn't mention seakayaking per se but I expect he would include it in the list, since sea kayaking is something everyone can learn.
While you can have degrees of risk - when a sport is inherently risky to start with, picking out a particular aspect of sport that might be more risky is a bit like splitting hairs.
In sea kayaking - once you leave the beach everything after that is a risk.



In this still from Will Gadd's Aweberg contribution at the Banff Film Festival he pushes the boundaries in order to make his film. Compared to his other climbs in the rockies and elsewhere, I would expect the technical skill to actually climb the iceberg is probably quite low, but the adventure interest is quite high. He was wearing a lifejacket.




In other sports - coaches and administrators make great efforts to manage the risk by educating all the participants, conducting courses and establishing some limits. In judo, competitors can be eliminated from a tournament - not just penalized, by carrying out a high risk move that can harm either an opponent or themselves. Yet, armlocks, chokes and all other throws within the international curriculum are acceptable.


What could be more risky than a hockey player not wearing an eye visor and then sliding in front of a slapshot?

Or in lacrosse, standing in front of a high powered shot from a running foreward.

If an organization provides education, training, safety seminars and skill development, they have done everything they can and need to do. People know they need thermal protection to paddle in the north atlantic but on those blistering hot days we know folks will and do wear only a sun/paddle shirt. That becomes their choice. People make choices all the time: not wearing a helmet in surf conditions, paddling on exposed coasts, paddling alone, paddling near whales and numerous other
common scenarios all of which involve more risk than the already risky sport of kayaking on the ocean.

It all seems relative to personal choice and your internal psyche - for a glimpse into what I think is a truly risky adventure sport - check out the film 20 seconds of Joy. This is an intrigueing glimpse of a norwegian female Base jumper and her sport experiences, including how and when her base jumping career came to a sudden halt changing her whole life.

East Coast Trail

If you can't kayak - hiking or cross country skiing are great second options. When the sun is blazing you tend to forget about the cold temperatures and the bitter wind coming off the atlantic. The recent addition to the East Coast Trail running out of Quidi Vidi is a great hike and quickly accessible. But we needed a little extra caution at this time of year. There were many hidden icy patches under cover of soft blowing snow and we found some sections of the trail are not as easy to find and a misplaced step, may be a land you in what in the spring or summer is bog.

Lunar eclipse

Kayakers spend almost as much time watching the sky as they do the water so
it was no surprise the lunar eclipse drew a number of folksout to follow this interesting event.
In St.John's, this past Wednesday night was a clear but cold night perfect for setting up a the tripod.
At it's brightest Saturn can be viewed in the northeast.

Exploring the World's Most Exotic Islands














CBC had an interesting discussion on this afternoon and one of the questions they asked was: how would you describe newfoundland and labrador?

I would have offered up: exotic

The discussion reminded me of the book Island Gods written by Richard Bangs and Pamela Roberson in 1991. Newfoundland received a whole chapter in this book so I think exotic is a deserving word. It is difficult to get a copy now, but I believe there may still a few available at amazon.com. In the credit section Mark Dykeman and Jim Price were recognized for their contribution in assisting Richard with his kayaking experiences. Many of the destinations described will be familiar to kayakers in the province: Ireland's Eye, Witless Bay(Great Island). Newfoundland is listed amidst some extraordinary destinations: Dominica, Bahrain, Sri Lanka and Lombok to name a few.

Consider picking up this book to add to your kayaking book collection.
