FIVE STAR SITE OF THE WEEK: Ayesha Rollinson, Triathlete.
"I grew up in Midland Ontario on what I now affectionately call the Funny Farm. My parents made sure they exposed us to as much as
they could when I was young. I competed in chess tournaments, I took Jazz lessons, I cooked by my mom's side (ok, I mostly measured
ingredients and licked the bowl), I went to nature camps.but it was the sports that I loved. The competitive sports. I loved the
feeling of winning. I loved setting tangible goals and reaching them. I loved the unbiased result of timed sports.
Sport is the frame if my life is a picture. It has always been there and it has held everything together. From age 8 until 12 I swam
competitively, then I decided to run with a competitive track team from 12 until 16. At the age of 16 I was recruited by the
national triathlon team coach at the time and turned my focus to triathlon. I competed seriously for 4 years, once winning the
Junior National Triathlon title and racing on the national team at 3 World Championships.
Once I started studying Engineering at University I could not continue to excel at the sport of triathlon with the time I had
available to train. Instead I decided that swimming with the U of T Varsity Team was more manageable. This turned out to be a good
decision for many reasons. First, I excelled under Byron MacDonald and Linda Keiffer. I came away from my 4 years having qualified
for and medaling at CIAUs. Second, the sport of triathlon became draft legal, which meant to be a top competitor you had to be a top
Upon graduating, I took 2 years to get back into the sport at a local and national level, winning a provincial age group title in
the process. I signed on with Adam Johnston and the Endurance Lab at the beginning of 2004 and that is when I hit the ITU circuit in
full force. Working with a team - including coaches, doctors, a sport psychiatrist, a nutritionist, triathlon Canada - on every
facet of my race I have been able to move up from being globally 'unranked' to being in the top 75 in the world in 2 short years. In
2005 I raced to 2 ITU podium placements and was named to the World Championships National Team."

THIS WEEK'S NEWS:
1. Multisport by Lance Watson: The Taper :
You've put in the hard work and there's a race coming up. What will you do to prepare your mind and muscles to step up on the day
and give you the performance you are looking for? One of the tricks of tapering is to allow yourself to freshen up without losing
feel or focus in getting ready for your big event.
For an Olympic distance triathlon with a moderate level of importance it is typical to work hard up until one week before the race,
followed by an easy day on Monday, some moderate work Tuesday-Wednesday-Thursday, and then have a very light Friday and Saturday
prior to racing on Sunday. Workload in the week of the race includes specific range of motion and threshold-maintenance type sets
that open up the arteries and remind you of what the effort and pace feels like. If you haven't raced since last season it is likely
that your body has forgotten the feeling of racing and pushing its max. Short, high intensity sets will reduce the "shock" factor
that your body might feel once the race gets under way but keep in mind you should not finish any set feeling completely empty or
fatigued. You may start to feel like you have increased energy due to a lower volume of work however be aware and keep in mind that
this is the time to rest and not push your limits. Push you limits during the race and save up for it.
To taper for an Olympic distance race with a high level of importance you should start to unload two weeks out. Week No. 1 has
high-intensity sets intermixed with more rest to maximize threshold boost and work on anaerobic capacity. There is no endurance
work. That means no long easy runs, rides or swims. Week No. 2 starts with two days almost completely off (perhaps a light swim),
followed by three very light days including small amounts of work at race pace (realistic race pace, not "dream race pace"), another
easy day on Friday, and some race-specific tune-up work on Saturday before the big race on Sunday.

2. Dr. Gabe Mirkin's Fitness and Health E-Zine:
* Rests Between Intervals Should Not Be Too Short
Athletes train by "stressing and recovering". On one day, they take a hard workout which damages their muscles, on the next day,
they feel sore and take easy workouts, and when the soreness goes away, take a hard workout again. They also break down individual
workouts into intervals of stress and recovery. After warming up, they increase the intensity of the workout until they feel burning
in their muscles, become short of breath, or exceed a certain heart rate. Then they slow down and when they have recovered
partially, they increase their intensity again. They repeat these stress and recovery intervals until their muscles start to stiffen
and they are then stop the workout. A report from The National Institute for Occupational Safety and Health in Morgantown, West
Virginia shows that the shorter the rest during an interval, the longer it takes to recover (Medicine & Science in Sports &
Exercise, August 2005).
If you are a regular exerciser, you probably have already noticed this in your own body. Runners may take an interval workout of
running ten quarter-miles averaging 65 seconds each, with a 110-yard jog lasting three minutes between each hard run. If they
shorten their recoveries to two minutes, they tire earlier, their muscles feel sorer afterwards, and it takes them longer to
recover. The same applies to weightlifters. A weightlifter may do four sets of ten repetitions of lifting a 150-pound weight,
resting for three minutes between each set. If he shortens his interval rest to one minute, he may not be able to finish his
workout, feels far more soreness during the workout and will be sore for many days after that workout.
Athletes learn their ideal interval rest durations through trial and error. They may want to rest until their pulses drops enough
for them to feel comfortable, or for them to be able to slow breathing rate down towards normal, or wait until their muscles lose
soreness and they feel fresh. They do not wait for complete recovery of resting heart or breathing rate, or complete recovery from
muscle soreness. Runners and cyclists often use heart rate monitors or a clock to determine when they will do their next interval.
Weight lifters usually wait for their bodies to "feel" recovered. You can use whatever yardstick for recovery you like, but if it
takes you longer than two days to recover from an interval workout, you are probably exercising too intensely, doing too many
repetitions, or not taking a long enough interval rest.

3. Multisport: Runners Stitch:
By Jenn Turner, BPHE (hon), DC, ARTR, CPTN- CPT, CCSS(C) (resident) - April 10/06
Exercise Related Transient Abdominal Pain - "Runner's Stitch"
Runner's stitch, or runner's cramp, is an injury that nearly every runner has experienced in the midst of or after a training
session. Although this pain affects approximately 60% of competitive runners (2) and also other athletes (4), there has not been
much scientific research conducted on this topic. The anatomic mechanism of the stitch is poorly understood. However, there are
several anecdotal-only suggestions regarding stitches available on the Internet and in running/athletic magazines. More scientific
testing in this area is needed as it affects a large number of athletes.
84% of the athletes, who reported the presence of a stitch while exercising, said it negatively affected their performance. Most of
these athletes simply reduced the intensity of their exercise while a few of these athletes had to stop exercising altogether in
order for the stitch to cease (5). In a competitive environment, neither of these options is desirable.
The scientific name for Runner's Stitch is Exercise Related Transient Abdominal Pain (ETAP.) It is a pain that occurs in the
thoracic cage when running. Usually runners describe this pain as sharp or stabbing usually at one side, and up under the ribcage.
Research has shown that the pain most often affects the right side and is more frequent and severe in younger athletes (2).
Unfortunately, according to the research (5), runners suffered the stitch more frequently than all other types of athletes. ETAP was
also found to occur commonly in horseback riders. Duathletes are also susceptible to this injury with the transition from run to
bike and back to run again.

4. Dynamic Duo - Running in Pregnancy:
By Elaine Cooper
First published in Australian Runner and Athlete magazine - March/April 1997.
Pregnancy, what does this word conjure up in the mind of the uninitiated, female runner? The obvious answer is that it's part of the
process of creating another little athlete. Yes, but what about the actual process, the nitty gritty of those amazing nine months.
What is it like through the eyes, or indeed feet, of a runner? Friends, family and complete strangers will ply you with graphic
details and advice even before that 'pink ring of confidence' has dried in your pregnancy test kit. You begin to contemplate nine
months of nausea, piles and a declining max V02, followed by another year of 'crawling legless' out of a mire of nappies,
breast-feeding, sleepless nights and exhaustion, trying to rebuild a runner from the ruins.
Its at about this stage that you start to seek out other women runners who have trodden the path before you. Unfortunately,
individuals vary. Some will depress you with tales of morning sickness and discomfort that brought their progression to a lumbering
halt in about the sixth month. Others will stretch your boundaries of belief with accounts of marathons, cross-training and of how
they didn't look pregnant until their tenth month.
Ingrid Kristiansen is one such immortal. She carried on her usual regime of 200 km per week and couldn't work out why she was a
little off par until she found she was pregnant in her fifth month. If that doesn't make you feel inferior, she also managed to run
a PB marathon (2:27) around five months later, despite dropping her running back.
Frustrated by a plethora of confusing and often, contradictory information, the runner seeks out the experts hoping for illumination
and a handy set of rules. The pregnant runner soon begins to realise that there isn't a lot of research being done in this area,
especially on subjects who have a reached a fairly high level of pre-pregnancy training.

5. Joe Henderson's Running Commentary - Talkathons:
Two of the best reasons to run have little to do with staying in shape or with training to race. These attractions are thinking and
They aren't opposites but companions. Team running lets you talk freely with friends, while solo running allows a heart-to-heart
talk with yourself. Both opportunities are scarce in a world long on loud noises and short on calm voices.
Running alone with my thoughts is my choice most days. This hour a day is all mine -- time away from the phone, radio and computer
that share my office, time to clear away the mental clutter so the good thoughts can bubble up. I don't carry pen and pad, but
usually come back from run with ideas begging to be captured on paper.
George Sheehan, one of the sport's all-time great writers, said he did his best "writing" away from his desk -- while running. He
treasured the solitary times "when I've been able to withdraw from the world and be inside myself. Such moments can open doors
impervious to force or guile."
Talk with runners fills the rest of my day, so I feel little need to run with them. If I worked outside the sport, I'd want to talk
my way into a partnership or group.
Something in the act of running -- the rhythm, the sweat, the common purpose, the stripping of outer roles and inner restraints --
loosens up one set of muscles above all others: those that operate the jaws. Listen in on two or more runners talking, and you'll
never again believe that long-distance runners are a lonely breed.
Dr. Sheehan balanced aloneness with togetherness. He once wrote that talking on the run "frees me from the polysyllabic jargon of my
profession, removes me from the kind of talk which aims at concealing rather than revealing what is in my heart... For me no time
passes faster than when running with a companion. An hour of conversation on the run is one of the quickest and most satisfying
hours ever spent."
Two of the best reasons for running, according to St. George, are contemplation and conversation. His third reason: competition,
which he defined not as competing against others but joining them to bring out better work than we could ever do alone.
A race is as different from a daily run as a private chat is from a public lecture. Conversing is easy, as taking a casual run is.
Speaking before a group is as hard -- and as fearsome -- as racing, but the audience brings out the speaker's best words just as a
race crowd brings out the best runs.
I've always enjoyed talking casually with almost anyone about almost anything. But the prospect of speaking in public used to
tongue-tie me with fear. I went through college hiding behind the tallest student in class to avoid being called on to comment.
Soon after graduation I was forced to take the stage at running events and later was doing it voluntarily. Now I look forward to
facing friendly crowds. The butterflies in my belly are now an expected and accepted part of the warm-up, as they are before any
Even George Sheehan, perhaps the most skilled speaker this sport has known, paced and stewed before his lectures. Once onstage he
spoke calmly and beautifully.

6. The ABCs of Heart Rate Monitors:
by Beverly Whelan
The size of a regular sports watch, a Heart Rate Monitor is a digital unit that displays your pulse. The pulse's signal is
transmitted wirelessly from a chest strap that accurately records the pulse from your heart vibrations. Most chest straps are so
comfortable and feel so natural that it's easy to forget you're even wearing one.
The features of Heart Rate Monitors vary widely; the most basic ones simply record and display current heart rate, as others come
with speed and distance devices and measure caloric expenditure. While those extra features are useful for certain types of
training, the most valuable feature is the heart rate measuring itself.
Resting Heart Rate
Before exercising with a Heart Rate Monitor, you need to know a few guideline numbers. First, you need to find your Resting Heart
Rate. This should be measured within the first few minutes of waking up. Just put on your chest strap and watch, and they will
automatically display a base heart rate number. Resting heart rate is normally between 60 and 72 bpm (beats per minute).
Variance in your Resting Heart Rate indicates a change in physiological state. It increases just before you get sick, as well as
when you are deficient of certain nutrients. For instance, anemia (low blood iron) increases a need for oxygen circulation by the
blood, and so increases the heart rate. It is wise to measure your heart rate every morning, in order to prevent or quickly cure
illnesses and deficiencies.

7. With effort, it's possible to improve distance-running times:
One question often heard from runners who have become racers is, "How do I run faster?"
The usual reply is, "Train faster."
Sounds easy enough, but how do we do it?
With top runners clocking five-minute miles or less for the marathon distance of 26.2-miles, and shorter distances being covered
well under that pace, what is their secret?
The top runners cover more ground in the same time as most of us do. This is done through a longer stride. Some of the top runners
cover nearly 6 feet in each stride they take.
At 5-minute-per-mile pace, most top runners take 90 strides, or 180 steps. That pace means they are covering 1,056 feet per minute,
or 5.8 feet per stride and this helps explain why they are so fast.
Most of us cannot cover that much ground because our natural stride length is far from that of an elite runner, and increasing your
stride length is very limited.
It is possible though, to increase our cadence, the natural rhythm, or turnover of our legs.
First, determine how many strides you are taking per minute by counting your steps for a half-minute, then doubling it to give you
your base cadence.

8. My 2006 Boston Experience:
By Clint Verran
I woke up five minutes before my alarm on Monday, April 17th, Patriot's Day in Boston. I took a hot shower and started filling my 8
fluid bottles with Powerade Advance. Halfway through filling my bottles, Brian Sell knocks on my door.5 minutes early. He was ready
to go. He helped me finish off filling my last couple of bottles, then we set off for the Copley Plaza Hotel, across the street.
At the Copley Plaza, we place our fluid bottles on tables marked for each 5K elite fluid station. Before we knew what hit us, our
coach Kevin Hanson has a 6 page course map with the current temperature and wind conditions for each stage of the race. "He's been
up all night" I think to myself.
Brian and I head back to the John Hancock Convention Center for breakfast. I eat a medium sized plate of plain pasta (no sauce), a
banana, a large banana-nut muffin, and 2 pieces of bacon. I wash it all down with some Gatorade Endurance and a cup of coffee. Time
to head back up to my room.
In my room, I double check the bag I'm taking to the start. Singlet with bib numbers, check. Racing flats with chip, check. Fresh
socks, Vaseline, hat, gloves, cell phone.check! I grab up everything I think I need and head down to the second floor, where John
Hancock race officials are staging the elite runners. The officials actually check MY bag to make sure I've got my bib number and
chip. While they check, they tell tales of professional runners arriving at the start in Hopkinton with 2 left shoes. What a
surprise that would be!
Our Hancock escorts take us down through the Convention Center lobby through a tunnel of volunteers clapping and cheering. The buzz
was definitely in the air. And the race start was still over 3 hours away. Brian and I piled into the 3rd of three coach-style buses
with about two dozen other athletes, coaches, agents, and race-volunteers. At exactly 9AM our bus leaves for Hopkinton.
As with 2002, I was amazed at how long the trip to Hopkinton is. This is despite a police escort! Keith Hanson was on the bus with
us and commented, "This is how the President travels." I said, "Yeah, or a funeral procession!"

9. Long Road Back:
Depressed? No way. She was a supercharged ultrarunner. She raced hundreds of miles on the toughest courses, and won. Then one day
Lisa Smith-Batchen woke up and couldn't run a step.
Lisa Smith-Batchen didn't even know why she was behind the wheel that afternoon in early 2005, until she saw the long plunge to the
rocky canyon floor beneath Teton Pass and it suddenly made sense. She hates heights, but for once the view didn't frighten her. It
felt restful. It felt-responsible.
"Everyone will be better off without me," she told herself. All the misery her husband, Jay, had gone through because of her. All
the terror her 5-year-old son, Joshua, had endured because of the mistake she'd made. All the chaos that 20-month-old Annabella had
been through. All because of her.
She hadn't planned to drive off the bridge when she set out this afternoon. Or had she? Was it a coincidence that after months of
barely being able to drag herself around the house, she had this overpowering urge to get behind the wheel and go? Maybe she just
refused to admit, even to herself, the real reason she was backing the van away from her home in Driggs, Idaho, and heading east
toward Jackson Hole, Wyoming.
"There's no other way you'll escape this pain," she told herself, which would have surprised anyone who knew her, because pain was
her fame; she'd made such a specialty out of mastering pain that she looked forward to it in a race, the way a power lifter looks
forward to the feel of steel. But a lot about Lisa had changed; her friends wouldn't have recognized her as the same freckled blond
beauty with the chiseled midriff who'd dazzled on the cover of Winning magazine a few years before, or who-just six months
earlier-had glowed at the completion of the first, and only, "Badwater Grand Slam."
To accomplish that, she'd run four major 100-mile races and the Badwater Ultramarathon, which stretches 135 miles across Death
Valley in the blistering heat of summer: 535 miles and 80,000-plus feet of elevation, the equivalent of 20 trail marathons in just
10 weeks. At one point during her adventure she had to red-eye directly from a finish line in Vermont to a starting line in
California. But when she had crossed the fifth and final finish line, Lisa looked as fresh and beautiful as the day she'd started,
beaming that apple-cheeked grin that attracts every eye in every room she enters.

10. SRM and PowerTap: How Accurate are They?
By Dr. Stephen Cheung, Ph.D.
Most of us have been inundated with the beauty of power as the purest and best training variable to monitor. Before jumping on
the power bandwagon however, it's important to understand just how accurate and reliable these units are. Fortunately, the Aussie
sports scientists have done exactly that.
Power to the People
It is no secret that the use of power monitors have revolutionized training in cycling, providing quantifiable data that advances
and complements heart rate monitoring. The problem however, even for the most well-heeled amongst us, is justifying the huge
financial outlay. Being a science geek, I'm not here today to sell you on the merits of power training (see our recent articles on
why Santa should bring you a power monitor and also on the power output of T-Mobile pros during a stage race), but suffice to say
that power monitors can be a vital cog in maximizing your training.
Accuracy and Reliability Defined
What DOES interest me, however, is whether these tools are accurate and reliable, which is by far the most important parameter in
monitoring tools. Accuracy refers to whether the tool is actually measuring what it claims to be measuring. In this case, is the
readout of 200 W on the monitor actually 200 W, or is it 210 W in reality? Reliability refers to the repeatability of measurement.
If an identical power (e.g., 200 W) is recorded on this interval, will the same power output read 200 W again the next interval? The
In many senses, reliability is the more important of the two parameters when talking about the utility of a tool, whether it be a
power monitor or a bathroom scale for measuring body weight. That's because, the vast majority of the time, the important thing is
not to compare your values with anybody else, but to track your individual response over time. To further the bathroom scale
analogy, it is more important that my weight reads the same when I weigh myself twice in a row, and not as important whether my
"real" weight is 64 or 65 kg.
What the Aussies do for Fun
Thank goodness for us that the sport scientists at the Australian Institute for Sport have a lot of toys on their hands, along with
the time to play with them. In a 2004 scientific article in the well-respected journal Medicine and Science in Sport and Exercise,
Gardner et al. (1) systematically tested the accuracy and reliability of two of the dominant power monitors on the market - SRM and

Sports Nutrition Tidbits
If you are eager to learn more about how to best fuel your body for top performance, you might enjoy muscling through three pounds
and 557 pages of Sports Nutrition: A Practice Manual for Professionals. The new fourth edition of this in-depth resource was
recently released by SCAN, the sports nutrition practice group of the American Dietetic Association. (It is available at
www.eatright.org. Click on Shop Online.)
Although this resource book is written primarily for sports dietitians, strength coaches, athletic trainers and other health
professionals who influence an athlete's eating practices, serious runners might also like to feast on this hard-core (but well
written and relatively easy to read) book that will answer all sports nutrition questions from A to Z, including alcohol, carbs,
calories, fats, fluids, protein, vegetarian, diet, weight gain, zinc-plus more! To give you a taste of the information in the book,
here are a few sports nutrition nuggets that might be of interest.
. The average 150-pound runner has only 1,000 to 2,000 calories of stored carbohydrates (glycogen), but over 80,000 to 120,000
calories of stored fat. Most of the fat is deposited in adipose tissue under the skin, but a little bit is also stored directly in
the muscles and is an important source of fuel, especially during long runs.
. Don't try to eat a fat-free diet! The recommended intake for athletes is about 0.5 grams fat/lb. body weight/day. This equates to
60 to 80 grams per day of dietary fat for runners who weigh 120 to 160 pounds. That's 15 to 20 teaspoons of butter! Preferably, the
fat comes from healthful sources: nuts, peanut butter, olive and canola oil, and avocado.
. While some fat is good, excess calories of fat are fattening. Your body easily stores excess dietary fat as body fat. That's why
you want to carefully carbo-load on pasta and breads, not fat-load on Alfredo sauce, butter, cheese or chips.
. Your body stores carbohydrates in the muscles in the form of glycogen (1,200 to 1,600 calories) and also in the liver (300 to 400
cals); this feeds into the bloodstream (100 cals) and fuels your brain. During hard training that depletes your muscle glycogen and
you enhance your body's ability to store even more glycogen; this enhances your ability to run for longer before "hitting the wall."
. Runners should eat at least 2 grams carb/lb. body weight per day. That's a minimum of 240 gm carb (about 1,000 calories) per day
for a 120 lb. woman and equates to 10 pieces of fruit or 5 cups of cooked pasta. Runners in hard training actually should eat 4 to 5
gm carb per pound body weight. No Atkins diet here!
. Adult runners require about 0.5 to 0.75 gram protein per pound (1.2 to 1.7 g pro/kg). Scientific evidence suggests if you eat more
than 0.8 gm pro/lb. (1.8 gm pro/kg), you'll burn the excess protein for energy. In other words, eating a very high protein diet does
not result in greater muscle gain, even with intense resistance training. To bulk up, eat more overall calories so you'll have
abundant energy to do the hard work needed to build muscles.
. Because eating before exercise can enhance performance. Research suggests you should target: 0.5 gram carb/lb body weight 1 hour
pre-exercise; 1.0 gram carb/lb 2 hours pre-exercise; 1.5 gram carb/lb 3 hours pre-exercise; 2.0 gram carb/lb 4 hours pre-exercise.
This means if you weigh 150 pounds, you need about 75 grams carbohydrates-about 300 calories-of carb one hour pre-run, and 1,200
calories four hours out. This tends to be far more than most runners consume. Experiment to learn how much your body can tolerate,
and try to build up to this target if you currently eat less than this.
. Consuming carbs during endurance runs can delay fatigue by 30 to 60 minutes. Target about 1 gram carb per minute of
running-equivalent to 240 calories of carbs per hour if you weigh about 150 pounds. That's about 1 quart of Powerade per hour.
. Consuming carbs as soon as tolerable after a hard run enhances muscle glycogen replacement because-
1) the blood flow to the muscles is faster immediately after exercise, so carbs can get carried to the muscles faster;
2) the muscles are better able to take up the carbs because of increased sensitivity to insulin, the hormone that helps
transport carbs into muscles. Plan to have banana, fruit yogurt, fruit smoothie, and/or fig bars readily available.
. Both liquid and solid carbs refuel the muscles equally well, so take your choice: chocolate milk or a pasta dinner.
. While many runners believe "thinner is better," don't try to get your body fat below five percent (men) or 12 percent (women).
Each runner has a fat percentage and body weight at which he or she performs best. Hence, you should listen to your body, and take
note of how you feel and perform, as opposed to force your body to achieve a self-selected number.
. Warning: Body fat measurements-even under research conditions-can be plus or minus three to four percent. If you are told your
body fat is 16 percent, it might be 13 percent or 19 percent. Just having a different person measure your body fat can significantly
alter the measurement. Use body fat measurements only as a guide and give yourself a body fat range.
. At rest, your body burns approximately 0.45 calorie per pound per hour. If you weigh 150 pounds, you burn about 70 calories per
hour of bed rest, or about 1,700 calories during 24 hours of doing nothing except staying alive. Doing moderate exercise, such as
brisk walking at a pace of 15 minutes per mile, you burn about 375 calories per hour. Running at a pace of 5.5 minutes per mile you
burn about 1,200 calories per hour.
Clearly, the harder you exercise, the more you can eat! But take heed: hard workouts followed by naps reduce your daily calorie
needs. Runners who turn into post-exercise couch potatoes commonly reward themselves with too much food and fail to attain their
desired weight goals.

The Brighter Your Veggies, The Better They Are For You!
Many of the natural pigments in fruits and vegetables are potent antioxidants, so the more pigment a fruit or vegetable has, the
more healthful it is to eat. Many berries are already naturally dense in pigment. So eat a variety of naturally brightly colored
fruits and veggies every day for maximum antioxidant punch.

14. Turn on the Power:
Energy System Specific Training.
We usually talk of energy in vague terms. "I don't have a lot of energy today," or "You can feel the energy in the room." But what
really is energy? Where do you get the energy to run? And how do you get more of it so you can run faster?
As our high school biology teachers taught us, the energy to move our bodies comes from the chemical breakdown of a high-energy
metabolic compound found in our muscles called adenosine triphosphate, or ATP. Simplistically speaking, running faster comes down to
increasing the rate at which ATP is produced so it can be broken down to liberate energy for muscle contraction.
Like many other animals, humans produce ATP through three biochemical pathways. The phosphagen system (also called the ATP-CP
system) uses our muscles' store of creatine phosphate and their small store of ATP to anaerobically power short bursts of running.
Anaerobic glycolysis, which occurs in the fluid-filled portion of cells, breaks down blood glucose and glycogen (the stored form of
carbohydrate in your muscles and liver) to get ATP. Finally, the aerobic system, which includes the biology teacher's
often-mentioned Krebs cycle and electron transport chain, uses blood glucose, glycogen, and fat to synthesize ATP aerobically in the
mitochondria of cells.
Despite the anaerobic nature of the phosphagen system and glycolysis, oxygen is still present. These two anaerobic systems simply do
not use oxygen to produce ATP, since that is a much slower process. Which system you use for the primary production of ATP depends
on how quickly you need it and how much of it you need. A sprinter, for instance, needs energy much more quickly than a distance
runner and will thus rely on different systems. The production of ATP is never achieved by the exclusive use of only one energy
system, but rather by the coordinated response of all energy systems contributing to different degrees.

15. Muscle Cramps: Don't Cramp Your Style:
Muscle cramps can ruin a run. Here's how to sidestep them for good.
At mile 18 of the Shamrock Marathon last March, Scott Young's right calf began to cramp. The sharp pain came and went for the last 8
miles of the race. "The worst cramp nearly doubled me over just as I crossed the finish line, keeping me from finishing the race
with my head up," says Young, 51, a social worker who lives in Virginia Beach, Va. Needless to say, Young's finish-line photo left
something to be desired.
His experience is common to runners. Muscle cramps are disabling, involuntary spasms that often occur during exercise or
competition, most often in the large muscles of the lower leg. Although, be aware: They can hit anywhere.
And once you've had these cramps, you never forget them. "Every time I go out for a long run now, the fear of cramping is always in
the back of my mind," says Young.
Muscle cramps are one of the most common medical complaints from athletes during endurance events, especially marathons and
triathlons, according to Martin P. Schwellnus, M.D., professor of sports medicine at the University of Cape Town, in South Africa.
No one really knows for sure what causes them, and there is ongoing debate on the subject. The theories are varied and range from
excessive heat, dehydration, and the loss of electrolytes, to muscle fatigue, insufficient training, and poor stretching habits. The
newest theories focus on the interaction between nerves and muscles.

16. Superfoods with oomph:
Fortify your diet with these natural, tasty star performers.
grandma have been right about carrots making you see in the dark? Human beings have always sought the fountain of youth. At the very
least, we want that elusive silver bullet that will keep us feeling bright-eyed and bushy-tailed well into old age.
Could it be garlic? Broccoli?
The hunt is on for superfoods: Foods with extra nutritional oomph, qualities that will supposedly combat all those vile trans fats
and vicious free radicals that cause premature aging. (Free radicals are harmful molecules that are blamed for cancer, heart
disease, even Alzheimer's.)
The superfood movement began as research into functional foods went mainstream when celebrity authors Dr. Steven Pratt and Dr.
Nicholas Perricone began popping up with books and appearances on Oprah and Good Morning America.
According to Edmonton health food retailer Shelley Robertson of The Big Fresh, "We're now looking toward whole food as supplements,
rather than vitamin supplements. Foods like acai (pronounced ah-sigh-ee) berries; in fact, most dehydrated berries (blueberries,
cranberries) are extremely high in antioxidants, and are aggressive free-radical scavengers."
Dale Wishewan, president and CEO of Booster Juice, is a huge fan of acai, and sells three different versions, all of which are going
"It's a terrific energy booster," says Mr. Wishewan, who sells it in his shops in Canada, the U.S. and the Middle East.
"A natural sports drink, it has the potassium and sodium we need for recovery after strenuous activity. It's also extremely high in
antioxidants. Acai, and matcha green tea, are both extremely popular with our customers."

17. Research Shows Anticipating Pain Hurts:
Researchers using brain scans to unravel the biology of dread have an explanation: For some people, anticipating pain is truly as
bad as experiencing it.
Anyone who's ever taken a preschooler to the doctor knows they often cry more before the shot than afterward. Now researchers using
brain scans to unravel the biology of dread have an explanation: For some people, anticipating pain is truly as bad as experiencing
How bad? Among people who volunteered to receive electric shocks, almost a third opted for a stronger zap if they could just get it
over with, instead of having to wait.
More importantly, the research found that how much attention the brain pays to expected pain determines whether someone is an
''extreme dreader'' -- suggesting that simple diversions could alleviate the misery.
The research, published Friday in the journal Science, is part of a burgeoning new field called neuroeconomics that uses brain
imaging to try to understand how people make choices. Until now, most of that work has focused on reward, the things people will do
for positive outcomes.
''We were interested in the dark side of the equation,'' explained Dr. Gregory Berns of Emory University, who led the new study.
''Dread often makes us make bad decisions.''
Standard economic theory says that people should postpone bad outcomes for as long as possible, because something might happen in
the interim to change improve the outlook.
In real life, the ''just get it over with'' reaction is more likely, said Berns, a professor of psychiatry and behavioral sciences.
He offers a personal example: He usually pays credit card bills as soon as they arrive instead of waiting until they're due, even
though ''it doesn't make any sense economically.''
So Berns designed a study to trace dread inside the brain. He put 32 volunteers into an MRI machine while giving them a series of 96
electric shocks to the foot. The shocks varied in intensity, from barely detectable to the pain of a needle jab.
Participants were told one was coming, how strong it would be, and how long the wait for it would be, from 1 to 27 seconds.

18. Easing race-day anxiety:
You're at the start line -- palms sweating, pulse racing, stomach churning. You're in such a state -- untying and retying your
shoes, jogging in place -- you're not sure you'll reach the first mile marker, much less the finish.
"Butterflies," multiple trips to the port-o-potty, even forgetfulness (Where did I put that packet of Gu?) are all classic signs of
race-day anxiety. And if you experience any of these symptoms, rest assured you're not alone.
Everyone from Olympic athletes to weekend warriors experience hiccups in self-confidence, putting their performance at risk.
But race-day nerves in themselves aren't bad. It's a matter of degree. A little nervous energy can elevate your body's adrenaline
level, enhance your alertness and build your competitive edge. Too much, though, can ruin your results.
So how do you stay in control? It comes down to mastering a few simple mental techniques, experts say.

19. The Complete Electrolyte Story:
Reviewed and Updated by ERB member Neal Henderson MS, CSCS: Director of Sports Science at the Boulder Center for Sports Medicine
Electrolytes, the mineral salts that conduct the electrical energy of the body, perform a cellular balancing act by allowing
nutrients into the cell, while helping to remove waste products. Certain elements, sodium, chloride, magnesium, calcium and
potassium, play a primary role in cellular respiration -- that of muscle contraction and nerve impulse transmission. It is at the
cell membrane where these electrolytes conduct electrical currents similar to nerve impulses. Hydration is the medium which aids
electrolyte transport and is crucial for both the health and performance of the cell. Your hydration state is mostly dependent upon
water intake or loss thru sweat but is also heavily influenced by electrolyte status.
Sweat: Endurance performance is compromised more by warmer temperatures than by cooler temperatures. Here's why: to control an
excessive rise in body temperature, the blood flow to the skin increases in order to dissipate heat to the environment. This shift
of blood to the skin will result in a lesser proportion of blood, and hence oxygen, being delivered to the working muscle. In some
individuals the circulatory adjustments may not be adequate and the body temperature will rise rapidly, leading to hyperthermia
(excessive body heat). Individual sweat rates vary, but those that sweat early, heavily, and cake with salt tend to be more prone to
muscle cramps during exercise (Burke, 2001). Evaporation of sweat in a hot environment can purge as much as 3 liters an hour.
Alberto Salazar reportedly lost an average of 3.7 liters per hour of sweat during the hot and humid 1984 Olympic Marathon in LA
(Armstrong et al. 1986). About 99% of sweat is water, with a number of major electrolytes found in varying amounts. Since sweat is
derived from the extracellular fluid (fluid outside the cell) the major electrolytes found are sodium and chloride. The
concentration of salt in sweat is variable, but averages about 2.6 grams per liter of sweat loss. Potassium, magnesium, calcium,
iron, copper, zinc, amino acids and some of the water-soluble vitamins can also be found in sweat.
Too much water? Hyponatremia is defined as a decrease in sodium concentration in the blood, which can have adverse effects on muscle
contraction and performance. One study observed 27% of participants following a three-day cycling stage race competition were
hyponatremic. Symptoms of hyponatremia include headache, nausea, muscle cramping, fatigue, and possibly death. Although there may be
many causes of hyponatremia, the most common one for athletes is overhydration. Athletes tend to superhydrate in the days leading up
to a race without an appropriate increase in electrolytes. In some cases, superhydrating can produce hyponatremia prior to the race
ever starting. However, drinking only water during a race can also causes hyponatremic conditions because the body requires
electrolytes to effectively maintain hydration status. Hyponatremia, rare in events lasting less than 4 hours, has been shown in
recent medical studies of slower marathon runners and ultra-distance triathletes to be at least as problematic and dangerous...if
not more so...than dehydration.
Sodium and Chloride: Sodium is one of the principle positive ions in the body's fluid and is found primarily outside the cell
(extracellular). Chloride, another extracellular electrolyte, is a negative ion and works closely with sodium in the regulation of
body-water balance and electrical impulses across the cell membrane. Consuming adequate amounts of sodium and chloride, more
commonly known as table salt, is crucial to maintaining the volume and balance of fluids outside your b<br/><br/>(Message over 64 KB, truncated)
