A bit of history (without going to the Roman times)

I have the genes of an athlete, but I did not know long. I have the genes of a geek - that I could not ignore. Son of a professor and teacher, grand-son of teachers, great-grand-son of teachers - pretty obvious I was born for the book rather than for sneakers.
But on the other hand, my father was a fairly high level athlete. Shot putter and discus (occasionally, hammer) thrower, sprinter despite his size (1.90 m), he tried also the 110-meter hurdles when his club needed it (once he became a local champion in this discipline). Volleyball (member of the provincial team at the time), karate and water polo are among the other sports he practiced.
When dad went to the athletics stadium, he often took me with him. And while he hurled the weight and the disc, I had fun in the sand for the long jump. Unfortunately, dad was unable to get me interested in the sport. Admittedly, I had some results in karate and I played ping-pong, but I do not show too much persistence.
Of course, with such a pedigree, one would hardly say that I had even a little bit of athletic talent. I was probably the last to think I had.

My first podium (if I can say so)

Yes, that's it. I knew- I'm in shape! Today at Scotiabank 5 km, I have proved. It was chilly, the wind was quite unpleasant, but I was ready. At 23: 19.9, I improved my personal best by 30 seconds (less than 1 / 10 sec, to be precise). Beyond that, I reached a 48th place amongst 768 participants and, even better, the 2nd place in my age group. No medal around the neck, but a second place is honest!
I thought I could do a good result for my last trainings seemed not too difficult (and yet they were demanding). But we can never predict what will happen on race day. For example, my friend Yves fell ill only two days before this race. All his hard training was in vain. But this happens even to the best.
In almost the same conditions, last year I made 23: 49.8. When I say so, I think on my parameters: heart rate of 166 (ideal, just a beat below my anaerobic threshold, the same as in 2009), the maximum heart rate during the race (175 compared to 174 last year), but the final time a lot better this year. Conclusion: I'm in better shape.
And my "pacing" during the race was also better this year. Thanks to my "magic bracelet" in Excel, I used the strategy of equal splits at every km, with a very fast final sprint. Thus, I avoided the "crisis of the fourth kilometer that was happening to me regularly on this course and I kept enough energy for the finish kick.
For years, I quickly began, then lost some speed at the first curve (with a small slope - this year the trainings at the Boulevard de Maisonneuve helped me greatly), and  with a slowdown in the fourth km, then the finish was not fast enough. This year - not the kind of errors. Next goal: under 23 minutes and it could happen already this year.

VO2 Max Test (2) - results

Finally, I received my VO2 Max. test results. Quite interesting!
Stage Speed HR Lactates VO2 Total Fat
km/h bpm (mMol) (ml/kg/min) kcal/min kcal/min
1 6.5 116 1.36 22.4 11.5 7.8
2 7.5 135 1.73 30.1 13.4 6.7
3 8.5 142 1.74 35 15.2 5.6
4 9.5 150 1.58 37.8 16.8 3.03
5 10.5 158 2.58 44.6 19.2 2.01
6 11.5 165 3.78 48.7 22.2 2.2
7 12.5 173 5.3 50.9 24.6 0
8 13.5 179 7.82 54.2 25.6 0
What does this mean? First, that my VO2 Max is 54.2 or superior, for my age.
Lactates (causing fatigue) and VO2 Max rise regularly, which means that I am in excellent physical condition. The anaerobic threshold is around HR of 167 beats, or when lactate exceeds the value of 4.
The last two columns show respectively the total consumption of calories per minute and how much fat I burn per minute. We can conclude that I burn the most calories from fat at low speeds (this is known), but the total calories burned are highest, of course, in the upper zones.
clip_image002[4]
clip_image004[4]
The graphs show the same things. We see that the curve of lactate (No. 1) rises suddenly after 4 mMol.
The other graph shows the linear rise of HR and Vo2 Max.
What surprised me the most was the distribution of my training zones.
Zone1 116-154
Zone 2 155-163
Zone 3 164-171
Zone 4 172-179
Zone 5 >180
Zones 1 and 2 (aerobic) are relatively high. My anaerobic threshold is in the middle of zone 3. So I can train more with FC high enough, without generating lactic acid. A lot more than what I was doing so far. And the more I train, the more I'll delay the onset of blood lactate and fatigue. Wow! This test was really worth it.

VO2Max Test

Since last Thursday, I feel like a real athlete. A true one. Because that day, I passed my VO2Max test. I did what the serious athletes do. It’s further evidence that I consider the race very seriously. Already I have a nice library of books of running, I read the serious sites, I use the technology for my workouts ... I was missing only the VO2Max test.
I did the test at the Centre Peak, downtown Montreal, on Mansfield Street. I was greeted by Caroline Brunet, the greatest athlete that canoeing has known. Seventeen medals in world championships and three Olympic medals are saying enough. With equal determination and a serious approach, meticulous and with the same enthusiasm that she has demonstrated throughout his career, Caroline helps athletes like me to test their VO2Max.
How it works? Following a ten minutes warm-up, Carolina put me a mask (with a tube like the one for scuba diving) attached to a hose, and I put a clamp on the nose to completely close it. Not easy to breathe. The slope is fixed (2%). From the initial velocity, she increases the treadmill speed of 1 km/h every three minutes. And with each change of level, Caroline has struck my finger to take a few drops of blood in tiny containers. This will be used to measure my blood lactate. At a speed of 13.5 km/h and heart rate of 178, I was afraid to do too much. I decided to give up. I could, perhaps, do a little more (3-4%, not more), but my mind was not strong. Anyways, I was already very close to my maximum. The detailed results will be ready in few days and Caroline will explain them to me. For now, I know that my VO2Max is 54. Not bad for a former obese. In fact, at my age, anything more than 46 is considered as excellent. Thanks to my dad for giving me good genes :) And big thanks to Caroline Brunet for her professionalism, enthusiasm and detailed explanations she provided me before the test. She is a great lady and a great athlete. She will be inducted in the Canadian Hall of Fame of Olympians in about two weeks. She really merits this honour.

Cotton T-Shirts

So, spring is back, nice weather seems to be here for some time and we run more often, isn’t it?

Recently, I was with my friend on Mount Royal. We ran under the warm sun when a girl just passed as by. Provocation! No, it wasn’t her, nor the fact that she passed us by, but the fact that she wore a cotton t-shirt. No, no! Just the fact that a runner wears cotton apparel makes me feeling bad.

So, what is that bad with cotton? Everything. It is the worst material in the world to put on when exercising (no matter the sport). It doesn’t wick the humidity (sweat), even on the contrary, it will absorb it, your tee will become heavy and uncomfortable and if there is a wind, you have all the chances to become sick.

Actually, polyester is much better and became the obvious choice for tees and shorts, and even the socks are made in materials that wicks humidity and allow to your feet to stay fresh and without blisters (great, it doesn’t stink and moreover it is comfortable).

Unfortunately, during our workout we saw several runners in cotton t-shirts.

Maybe they just don’t know that polyester exists (I frankly doubt, but…) or think it is too expensive. No, polyester tees are really not expensive and you can wear them for years. They dry quickly so can be reused after several hours. The top models offer even the UV and antibacterial protection (no smell!). So, what are you waiting? If you already don’t have one, go to your running store and buy a polyester T-Shirt. You’ll feel much better under the sun.

Fit, in spite of the age

Another day, I read about Buster Martin, a 101 years old Brit who recently finished a half-marathon (the time is really not important) and is preparing for his first full marathon - London Marathon, in few weeks.

Almost every day I see in a gym men in their 70s, doing their workouts on a treadmill or with weights (not too big, to be honest, but anyway).

And finally - my source of inspiration since I started running - a phenomenon called Ed Whitlock. This Milton (Ontario) resident, born in 1931, is a real running machine and an exceptional motivator. Can you imagine - this man, record holder of 13 world records in different age categories, ran a full marathon (42,195 km, 26 miles 385 yards, use any unit of measure you like - it's veeery far)in less than three hours. At the age of 75! He runs between 2 and 3 hours every single day. What his heart looks like? I can imagine it as a well oiled (not because of the fat) and maintained pump that will function for many years to come. The idea is to do the workouts, stay fit and help out body to continue doing well even at the advanced age and preserving our physical and mental health - without using the drugs. We really don't need to stimulate the pharmaceutical industry. They are already too rich. Let's rather help ourselves to stay healthy at the age of 70,80, 90... years. I can't imagine myself running a full marathon in less than 3 hours at the age of 75 (like Ed Whitlock did), but running 5 or 10 K at the ago of 65 - why not? And after that, we'll see. It's already much better than most of the people around us do.

Add some jogging?

I hope that some of you started fitness more than six months ago. If so, you might be interested to introduce some jogging into your daily activity. About a year after I started my weight lose program, I started to jog occasionally. Then, I felt that I needed some more speed. If you are like that, the following program is for you. If not, continue with you current program until you achieve your goals.

WARNING:If you have heart related problems or you just think you might have them, consult a qualified physician before you change a program.

Program for advanced walkers/joggers

Day Intensity
Monday (day off)
Tuesday (short day) Warm up for 5 to 10 minutes; 30min @ 50-70% MaxHR (alternate 5 min walk/ 1 min light jog)* ; slow down for 5 minutes. Light stretching.
Wednesday (short day) (same as Tuesday)
Thursday (long day) Warm up for 5 to 10 minutes; 60 min @ 50-70% MaxHR; slow down for 5 minutes. Light stretching.
Friday (short day) (same as Tuesday)
Saturday (long easy day) Warm up for 5 to 10 minutes; 30 min @ 50-70% MaxHR; 30-60 additional minutes @ 50-60% MaxHR; slow down for 5 minutes. Light stretching.
Sunday (long day) (same as Thursday)

*Every four weeks, you can increase light jog by 1 min until you walk for 5 minutes and jog for the same amount of time. Your total workout time shouldn't change (max 30 min). Only the number of intervals will change.

BTW, this will increase the amount of calories burned, and if your goal is a weight loss, this will help you to get rid off the pounds a little bit faster.

Interesting question

Last Sunday, I was running in a park. I was doing my workout for several minutes when one of the two ladies in their 70's or 80's, sitting on the bench, asked me the following question: "Why do you run, Sir?". Without hesitation, I sincerely answered: "Because I like it!"
I continued running, but few minutes later, probably not convinced that somebody could run for pleasure, the lady asked me the same question. I stopped and explained her how I lost weight, started walking and running, etc. I finished with the same sentence as few minutes ago: "And now, I run because I like it."
This is true. I am not obliged to run but I like it so much that I cannot stop doing it. I hope you'll like walking and, eventually, running, too.
This is no more a matter of fitness or health. This is a Passion!

Did you start to walk?

Try our poll (left) and be honest :). It's for your good.

If you already started - BRAVO! Just go on! IF you want to start, but don't find some time, try something else: use the stairs instead of the elevator, walk to the store instead of driving (well, if it isn't at 10 km). The well known tricks :)

If you want to progress (hey, it means that you already walk!), I offer two beginners programs. Find some time for yourself 3 or 4 times a week.

 

Beginners 1 (less than 4 weeks of walking):

Day

Time Effort
Monday 20-30" 50 - 60% maxHR *
Tuesday

Wednesday 25" 50 - 60 maxHR
Thursday

Friday 30" 50 - 60 % maxHR
Saturday

Sunday 15" 50 - 60 % maxHR

* maxHR = maximum Heart Rate (see 2007-28-02, Workouts with Heart Zones)

Beginners 2 (between 4 and 8 weeks of training):

Day Time Effort
Monday 30-35" 50 - 60 % maxHR
Tuesday    
Wednesday 30" 50 - 60 % maxHR
Thursday    
Friday 30" 50 - 60% maxHR
Saturday    
Sunday 15" 50 - 60% maxHR

I started like this... and you can do it, too! Next time - for advanced walkers.

Isn't it fantastic? A crowd of 25 000 gathered this weekend in Montreal to walk and run for Canadian Breast Cancer Foundation.
Everyone can do something to help find the cure for breast cancer - a donation and a participation. Every little thing that gives hope that one day this illness will disappear or, at least, be easier to prevent and cure.

Together, we can do more than individually, so let's run, walk, meet... For a new hope and a better future of women and men (yes, event the men can have this form of cancer - only this year, 170 men in Canada, 80 in Austria, etc. will be diagnosed with this illness). And gather in even bigger number next year!

Is Running Really Boring?

When I was younger, I often watched a very long dyke in my birthplace (well, maybe I just thought it was that long). And, there were runners, too. I wondered how they could run every day without being bored.

Another day, while I discussed with my dad (a former athlete, but not runner), I mentioned running and he told me that running on streets is probably interesting, and running on track must be “terribly boring”.

Few years ago, I would have thought he was right. Not anymore!

To walk or run, one must have good legs (strong, not pretty), but the mental side is also important. A physical activity is equally a matter of muscles as of thinking.

When I started to walk, I always used my PM3 player and listened to the music. Once, I forgot it (but it was too late to come back).

So, I started making music in my mind and understood that my brain was there to motivate me. Some time later, I understood that the workout time is my special time for relaxation.

That’s when I am concentrated only on running and on my environment. Even now, I use some songs in my mind to find a good rhythm for running and since one year I don’t use my MP3 during the workouts.

Do you still remember the dyke from the beginning of this post? It is still as long as before, but now I know I can pass from one end to another very fast. Neither running on track is boring. I understand that this way I can improve my performance, especially the speed.

So, what is the answer to the question from the title? Definitely, running is not boring. It is only our perception (when we are not motivated) that makes it boring.

So, go outside and move…

What I ate?

IMPORTANT: Don't even try to eat like me. Our individual needs are different (according to our physical constitution, metabolism, level of the physical activity, etc.).

This is only an example of my menu. Don't change anything in your eating habits without consulting a qualified nutritionist.

Breakfast: a glass of cereal with a glass of milk, half banana

Variant: Two slices of multigrain bread with peanut butter and a glass of milk

Snack: one fruit

Lunch: Meat or fish; two slices of bread or potatoes/pasta; lettuce or tomato, ten pieces of baby carrots

Snack: one fruit

Supper: If I ate fish for lunch, I eat meat and vice-versa; cooked vegetables/salad; bread, potatoes or pasta

Before going to bed: a glass of 1% milk or fat free yogurt

I ate (and still eat) a lot of fish (salmon, tuna, sardines, mackerel). I use canned or fresh fish - the latter prepared in the oven or in microwave with a lot of spices and some olive oil. It helped me to get rid of cholesterol.

When you see what I ate, are you surprised I wasn't hungry?

Montreal Marathon's 5 K (Sep. 9)

 

I am so excited! I set my new personal best on 5 K (24:20).

It was a great race. For the first time I was faster than 25 minutes (my old PB was 25:27). The weather was fair (around 15°C, somewhat windy) and I was in great shape.

Unfortunately, on the water stop, a guy in front of me stopped suddenly so I ran into him and lost few precious seconds and my rhythm was broken.

My running buddy Yves avoided this situation. He set his new PB, too.

One of my toes is painful (did the guy at the water stop stepped on my foot?) but I'll continue my workouts this week preparing for the next race (in 3 weeks).

Start using a Heart Rate Monitor

What’s the use of a heart rate monitor?
1) You don’t have to stop occasionally to measure your pulse.
2) You can set the alarm so whenever you are too low or too high (if you prefer: when you are out of your training zone), the alarm will remind you to accelerate or to slow down a bit.
3) You can set the timer to remind you when to stop the workout.
4) At the end, you’ll see the statistics (average heart rate, maximum and minimum HR), sometimes even the total time you exercised in your target zone.
You can put all of this to a chart and this will motivate you more than you imagine. I was so amazed with these numbers that I entered them after every workout and was impatient to do. You can even add your morning weight and calculate the daily or weekly progress. Amazing! I did it after two months since the beginning f my program and it was one of the most motivating things I used.

As it was written on About.com - Sports Medicine, Heart Monitor is a gadget you can live without, but once you try it, you’ll be hardly able to continue without it.
Right, you become addicted! You find it so easy to use and so useful, that you want one during each of your workouts. HRM is not a tool for advanced athletes (although they use them, too). You can find them in various shapes, with so different characteristics – from base models, to fitness and running or cycling computers. Every one will monitor your heart rate in real time, most of them have the chronometer, most will be able to set your five heart zones (but you’ll have to enter your maximum HR yourself), some can even calculate your calories consumption during the workout. Mostly, they have a timer, so you can set the time you want doing your workout (ex: 24 minutes) and will remind you that your exercise is over.
The advanced ones will show you the distance you walked (or ran) – based either on GPS signal or by using a foot pod. Some will even allow you to set your workouts on a computer and to transfer them to your watch and exercise according to the programmed session. Some of the famous brands are Polar, Timex and, recently, Garmin. Polar and Timex have basic to advanced models, Garmin only the advanced ones. I would not recommend the Heart Rate Monitors without a chest strap because they are not accurate.
Basically, you moisten your chest strap and put it on your chest, start your watch in chronometer mode and GO! Don’t forget to warm-up and cool down!

My first month

As 3 weeks are needed for any activity to become a habit, it is obvious the importance of my first month. I started on April 10, 2005, and then I did my workouts every other day (twice, I skipped one day, but I did my workouts the day after). Generally, the effect of a workout lasts for 48 hours, so sometimes there is no problem to skip an additional day. The average time I spent on my workouts at that time was around 30 minutes and I walked around 3800 steps (about 2.7 - 2.8 km), with the average speed of a little bit more than 5 kph.
In fact, I started with 3780 steps/30 minutes and at the end of the month (after 11 workouts) I did 4550 steps/35 minutes.
At the end of May (1 and a half months after I started), I walked 45 minutes and around 6500 steps. In the beginning, I didn't do any statistics about the lost weight, but between April 10 and May 15, I lost 11 kg.
Not everybody must and can lose that weight so quickly, but it is quite obvious: when you are obese, you need more energy to move than when you are lean. Just imagine pushing a 10 kg box and a 50 kg box. For which one will you need more effort?
Moreover, I drastically cut in my calories intake, especially sugars. Probably I also dehydrated a little bit because I was taking some water only when I was thirsty. Now, I know it was wrong. You should drink water regularly,
before you feel thirsty because it means that you are already dehydrated.
The marathoners do it like this (me too - now): one or two sips of water every 10 minutes of workout, no matter if you feel thirsty or not.

Running Room 3 miler Race - Aug 11, 2007

Hear are some photos taken during my second race this year - Running Room 3 miler , that took place last Saturday on Mount Royal in Montreal.
The weather was great, my result good (10th place among 59 racers, 3rd in my age category where I was the oldest), everything was really great.

Taking heart rate and the first workouts

There are many ways to measure your heart rate, but the most accurate is by using a Heart Rate Monitor (HRM). While you walk or run, you can see in real time your heart rate.

If you don’t have a HRM, you can stop and take you pulse on the neck or on the wrist, but don’t forget that your heart rate will continue dropping while you are stopped. This means that there will be a discrepancy compared to a heart rate while you run or walk.

When you calculate the limits of your heart zones, try walking in a pace that will allow you to stay in your defined zones (1 or 2).

Before starting every workout, warm up by walking for five minutes – you have to gradually increase your heart rate from below 60% to a desired level.

After the workout, cool down by gradually decreasing your speed for 3 to 5 minutes to avoid that the blood (used while you were walking) returns too fast to the organs and in order to relax the muscles.

For the first week, I would recommend 15 to 20 minutes of walking in the first two zones (plus warm up and cool down). This gives the total of 25 to 30 minutes of activity. Try to exercise every other day or at least three times a week but not three days in a row and do not skip more than two days.

If you feel a chest pain or fainting or any other similar symptom, stop your activity and immediately consult a doctor. In normal conditions, if your intensity is not exaggerated, you shouldn’t have problems.

Also, do not start exercising without asking permission from your doctor, especially if you had any past heart condition.

During the workouts, take one or two sips of water every 10 to 15 minutes (depending on your sweating and the air temperature/humidity) and avoid exercising during the heat periods. This means that in summer the best time for workouts is either early in the morning or late in the evening.

Don't forget - do not exercise at least 1.5 or hours after a meal and don't eat for at least 20 minutes after the workout. However, 30 minutes after the workout are important for recovery so take, for example a cup of chocolate milk (not too cold!) or cocoa or any other similar combination of proteins and carbs after the exercise. I found that the chocolate milk works perfectly for me.

Workouts with Heart Zones

One of the most helpful things that helped me to lose weight was exercising with the Heart Zone.

To avoid too many scientific details, I’ll simply try to explain what it is.

The top triathlete Sally Edwards (today in her 50’s) is one of persons that prone this kind of fitness preparation. By simply following her advices, I lost weight and achieved the fitness level I could only dream of when I was younger.

The theory says that everybody a maximum heart rate (MaxHR). This number is not age dependent, is inherited and is sport dependent. Although there were many proofs that the widely accepted formula is no more valid (there is a difference of up to 20 beats compared to a real world data), the formula is still in use. This formula is based on a person’s age and now we know that a fit person can preserve its high maximum for years.
In the beginning, I also used this formula and lost quite a lot of weight (but later, I replaced it with another one, more precise), so it can be a kind of starting point.

So, let’s start with this formula that states:
MaxHR = 220 – age (in years)

In theory, a person 30 years old has MaxHR of 190 (220 -30)=190. Someone 50 years old would have MaxHR of 170.
Just to show the discrepancy, I’ll give you my example: I am 49 years old and my MaxHR, according to the age-dependent formula, would be 171 (220 – 49). In practice, I already run at 182. According to the other formula (that I use now, but I’ll explain it later), my MaxHR would be 180. Not bad: 2 compared to 11. It can be almost a whole zone!

Then, depending on this value, we can calculate the 5 heart zones used in workouts:

1. Healthy Heart Zone: 50 to 60 % of MaxHR-a (this zone will be used to warm up and cool down)
2. Temperate Zone: 60 to 70 % of MaxHR
3. Aerobic Zone: 70 do 80 % of MaxHR
4. Threshold Zone: 80 do 90 % of MaxHR
5. Red Zone: 90 to 100 % of MaxHR

If you want to preserve your heart (without using the benefits of other zones), use the first zone. You will notice that your blood pressure will be lower after some time.

The second zone (together with the first one) is the one in which you’ll burn the maximum of fats so these zones are used to lose weight. The total of burned calories is higher in the second zone, but in both of them, 85% of all calories burned come from fat. It is also good to lower the high cholesterol, with the changes in nutrition.

The third zone is the aerobic and helps to improve the endurance. In this zone, 50 to 60 % of all calories come from fats (higher total calories, but lower percentage from fats).

The last two zones are for the athletes and the percentage of calories burnt from fats is low.

It means, in order to lose weight, you should exercise in the first two zones, and when you become a lot less heavy (to avoid the injuries), you can occasionally exercise in the third zone (easy jogging). It is not worth of trying while you are still very overweight because there is high risk of injuries.

Example of zones:

For the 30 years old person with MaxHR of 190, these are the zone limits:
1. 95 to 114 heartbeats

3. 133 to 152 heartbeats
4. 152 to 171 heartbeats
5. 171 to 190 heartbeats
