Tips for Winter Exercise

Most rowers in North America and elsewhere have left the water for the winter. Even those lucky enough to have year-round water for training may be looking for some alternatives at this time of year.

The Mayo Clinic is one of the leading medical institutions in the world and they publish a web site "tools for healthiere lives". Today's postings include an article on winter training tips to stay motivated and safe in the cold.

The article includes links to other exercise related posts inluding one about when it is safe to continue exercising if you are sick - another timely post in the winter. IT essentially says that symptoms "above the neck" such as sore throat, runny nose etc. are OK and you can continue training - when the symptoms hit the rest of your body it is time to take a rest.

Surgery for Disk Problems Not Only Option

An article today on the CTV website reports on two major U.S. studies recently that suggest surgery for a herniated disk may be no more effective than waiting, physiotherapy and painkillers.

Surgery seems to alleviate pain more quickly, but after two years both studies showed no difference between those who had surgery and those who did not.

This was not a random trial - patients chose their treatment which may well affect the results. One could presume that a patient in more pain (more serious condition?) would be more likely to elect surgery.

Malignant Melanoma Risk in Marathon Runners - Warning for Rowers?

A recent article in the Archives of Dermatology reports an observed increased risk of malignant melanoma in marathon runners. It was felt that long periods in the sun, possible immuno-suppression from intense exercise, and that fact that just half the runners observed regularily used sunscreen were causal factors.

This should serve as warning to rowers who spend at least as much time on the water, and in my experience, are not great at lathering on the sunscreen.

Does it matter how frequently you exercise and eat each day?

The Harvard HealthBeat Newsletter reported on several studies examining the frequency of eating and exercising this week.

Looking at a number of studies involving significant numbers of people confirming the old belief that it was healthier to be a "grazer" eating several smaller meals each day.

When the scientists tallied the results, they found that the people who ate more frequently took in more calories. Surprisingly, though, they also had lower cholesterol levels. The difference was relatively slight, about 5%, but it was consistent and significant, even after exercise, body weight, smoking, and other factors were taken into account. In all, the researchers found that people who eat six or more times a day have cholesterol levels that should reduce their cardiac risk by 10%-20% compared with people who eat once or twice a day. And male (but not female) 'grazers' were also leaner than 'gorgers,' even though they took in more calories.
A number of studies looked at exercise in a similar way - albeit with older populations - and found that it did not matter whether one exercises for thirty minutes once, two times for 15 minutes in a day or even three bouts of 10 minutes in a day.

What does this mean to you? Well, it is nice that recent studies confirm what we have felt for a long time abotu eating frequency. As to the exercise frequency, I'll assume most readers of this blog tend more to several LONG sessions in a day - I haven't seen too many people go out for three ten minute rows in a day! If there is one bit of information though - perhaps it is OK to limit the time on the water on multi-workout days, and it certainly helps technique many feel - but those points are far different ones than addressed by these studies.

Simulating Altitude During Training

A "pilot" study - one conducted to see if there is enough reason to conduct a larger more controlled study - was published ot of New Zealand that looked at an inhaler that reduces the percentage of inspired oxygen so that an athlete can simulate training at altitude. "The effect of intermittent hypoxic training via a hypoxic inhaler on physiological and performance measures in rowers: a pilot study."

It does not come as a great surprise that there was actually a decrease in mean power during a 500-m test and the mean power at the 4 mmol lactate level after training with the device. In fact, most high level athletes now prefer to live at (or simulate living at) altitude while training near sea-level which is essentailly the opposite of this study. It is felt that with reduced oxygen levels during training athletes are not able to train at a high enough intensity - somethign this new pilot study would seem to confirm.

Concept II PM Underestimates Power Measurement

A new study published in the International Journal of Sports Medicine - (Power responses of a rowing ergometer: mechanical sensors vs. Concept2 measurement system. Int J Sports Med. 2006 Oct;27(10):830-3. Epub 2006 Apr 11.) suggests that the Concept II Performance Monitor underestimates the actual power produced as measured by strain guage sensors applied to the handle by some 25W. This would only have an impact on researchers - but if like the weightlifter who likes to tell the world how much he can "bench" you like too brag about your erg power - feel free to add 25W to your measure!

Tip to Keep Your Water Bottle Mould Free

One of my favorite non-rowing sites is "lifehacker.com" Today they present a nice little tip for ensuring that your water bottle stays clean. After washing - put it in the freezer.

As cold water is absorbed faster than warm I'd suggest a small modification to this tip - add some water to the bottle first - then top it up when you take it out for the workout - instant ice pack inside that will thaw out during your workout on or off water. Depending on the length of your workout and the temperature where you'll be exercising you can modify how much water to freeze inside the bottle.

The same site includes an article with ten tips to help workout recovery.

For Rowers Who Want to Grow Taller

Can you grow taller? What rower hasn't wondered about this!

Of course most of us know that there is little or nothing that we can do to influence our growth but do you believe that there are people who try to sell products to help with growth?

Since height is a common desire amongst rowers it's well worth knowing about growth, especially if you coach younger athletes.

See this article for more about the physiology of growth.

Does Birthday Matter in Team Selection for Rowing?

An interesting study has just come out of the University of Saskatchewan about young hockey players that is at least food for thought amongst rowing coaches. It says that those with late birthdays are less likely to be selected for teams, presumably because those born earlier in the year are more likely to have already hit their growth spurts. This despite the fact that those passed over had the same predicted future height.

In fact 75% of those on provincial and national teams studied were born in the first half of the year! To those selecting the teams, they are only choosing the best players at the time. Unfortunately, the late bloomers aren't recognized and may be "filtered out" of the sport when they lose out on opportunities.

What is the responsibility of a coach to the future of the sport? If you cut kids from a younger crew, they may well drop out when they could have been the future of your team.

Does this apply in rowing?

An interesting addition to this piece is a link to the University of Saskatchewan web site and a tool for predicting future size in adolecents.

Static versus Dynamic Warmups

Static vs. Dynamic Warm Up

Static stretches are the only way to go we're told. Avoid dynamic stretching, it can cause injury also is often heard.

For these reasons a study on static vs. dynamic warm ups caught my eye. The study, titled Dynamic vs. Static-Stretching Warm Up: The Effect on Power and Agility Performance was published in the latest issue of the Journal of Strength and Conditioning Research.

While the effectiveness on brief anaerobic performances was assessed (medicine ball throw, shuttle run and a 5 step jump) and there can't be an obvious link with rowing the study is interesting food for though nonetheless.

The results suggested the dynamic warmup produced better performances on all three measures than either static or no warm up.

Obviously in rowing we have a long period of dynamic warmup - there is no choice if you want to get to the start! But if you are a firm believer in the warm up that takes place before going on the water, or in the warm-up before an erg this should at least make you pause and think about how you use that time. How many coaches have seen young athletes show up for an erg test, do a bunch of static stretches and very little actual rowing before the test?

Rowers taking up Marathoning Take Note

A good article recently appeared on the CBC Web Site on running marathons safely, in the wake of a recent death at the Toronto Marathon.

While not rowing, I know lots of rowers have either run a marathon or set the goal of working towards one as part of their training.

The article mentions a few ways of reducing the risk, while at the same time points out that death in marathons at about 1 per 100,000 carries a very low risk, especially when you consider the reduced risk of serious disease seen in runners, compared to sedentary people sitting at home on the couch.

Sudden Death Syndrome and Rowing - Should All Young Athletes be Screened?

When browsing through some new publications today I came across one that lead me to consider an even more significant issue - Sudden Death in apparently highly trained athletes.

The article that first sent me on this track does not address the issue of sudden death at all I must say clearly. This month in the Journal of the American Society of Echocardiography a study titled Myocardial Adaptation to Short Term High Intensity Exercise in Highly Trained Athletes was published out of the Harvard Medical School and the Massachucetts General Hospital. The authors screened the hearts of 17 participants from the 2004 CRASH B World Indoor Championshipss, before and after the event. The findings are too technical for all but the very well trained in medicine and cardiac physiology but to put it simply - the heart is affected by short term intense exercise in even highly trained athletes.

We often fall off the erg with a very clear understanding of the pain we experience. The burn in every muscle in the body is obvious and our respiration rate seems uncontrollable, even leading a few to the oxygen mask. But - do you ever consider how your heart feels about it? If your legs give out you cannot stand - but there is recovery eventually. If the heart gives out?

Over the last few years we have seen reports of the sudden deaths of highly trained athletes - basketball players in their prime on the court, football players, and yes, even rowers. The reasons are diverse and complicated and I would never want to trivialize them by suggesting that I am capable of summarizing them in a short blog post. But the reminder that the most important muscle in our body is clearly affected by a 2000 m erg test was still a sobering thought for me today.

It brought to mind something else I came across a few days ago - a report that all children in Italy now have their hearts screened before engaging in a sports program! It also notes that the European Society of Cardiology recommends that all young athletes be tested. What do they mean? A simple trip to the doctor as is suggested in most countries? Yes. But they also suggest a 12-lead electrocardiogram (ECG)!

Does this seem excessive? perhaps expensive? Consider this: since begining this program Italians have seen an 85% decrease in cases of sudden death in young athletes. The cost is mandated to be about $40 per child.

The statement that usually seems so trivial: "please consult a physician before engaging in an exercise program" has a lot more meaning for me now.

Soft Drinks Fuel the Obesity Epidemic

A press release from the Harvard Health Letter recently came out that was interesting. It reports that Americans consume some 100 pounds (!) of sugar per person, per year. Many people don't realize the calories they consume in soft drinks and even in sports drinks that are touted to be healthy. When people take in these extra calories they don't restrict their intake elsewhere to compensate.

One result? Women who drink one or more sugar sweetened dirnks per day at 83% more likely to become type II diabetic.

Stretching Does not Prevent Muscle Soreness?

An artcle from the British Medical Journal reports that stretching before or after exercise does not prevent muscle soreness. This was a review of five studies of "moderate quality" and suggests that stretching does not reduce soreness from exercise, nor does it prevent injury - based on a study of army recruits.

My experience with army recruits suggests that the training is so hard nothing could prevent injury - but that's another story!

This article does not address the issue of stretching improving sport performance though and other research does suggest that there is a positive relationship between the two.

To see the abstract of this article:

Stretching before or after exercise does not prevent muscle soreness or reduce risk of injury: systematic review BMJ Volume 325 pp 468-70, 451-2

Rowing and Long Term Athlete Development

Rowing Canada has a lengthy document I recently came across about Long Term Athelte Development. It seeks to examine all the factors that go into the development of an elite athlete, and is an interesting read, especially in light of the fact that Rowing Canada has not renewed the contract of thier current National Junior Coordinator and are rexamining the structure of the entire junior program.

While comments were disabled for a while on the blog, I have since re-enabled them. I'd love to know your thoughts on LTAD. How does your country handle it? I have heard several knowledgeable people suggest that the World Junior Championships are not a reasonable goal if an athlete wishes to train in accordance with a proper LTAD model. Some junior athletes are putting in more hours and miles than elite senior athletes - does this hurt their development? Is this setting them up for injury? What about all the other parts of their life that they miss out on?

Does the length of a rowing shell matter?

Does the ength of a rowing shell matter? Is the shorter design of the Resolute more effective at reducing drag?

Pocock has a new series of articles and address the issue in todays posting. It does not seem to take a firm position - only discussing therelevant factors - although at the end it becomes clear that they are leaning towards the longer hull with their new 8+.

The discussion of drag as it relates to wetted surface area and wave drag is interesting and clearly shows that there are no easy answers.


A great deal of time and energy and money went into some of the research that has made shorter hulls more popular recently - what do you think?

How to handle morning workouts

It's that time of year again, and lots of us are up in the early hours to train. This is far from science - but just thinking about it is fun(?). SO, how can you make it a bit easier?

If you havew any ideas send them to me, please!

1. Have your kit packed the night before and your clothes laid out - I'd sooner spend 5 minutes in the evening in exchange for 1 minute of extra sleep.
2. Have a routine! That includes bedtime. Your body will thank you.
3. Have a commitment - if you're in a crew you get it. Knowing 8 other people are waiting for you will get you out of bed.
4. Buy a coffee maker with an automatc timer. Starbucks isn't open where I live at 5 AM.
5. Get a bit of exercise in - seriously. Warming up is even more important because a) it's colder in the morning and b) you need to get the mental cob webs out.
6. See #5 and mental cob webs. There is a danger in the morning that you will just go through the motions if you are not prepared for the workout. I posted a while back about mentally preparing for a workout and I think it goes double in the morning. Focus - the last thing you want to do is get up early and then waste your workout.
7. Coaches - have a plan, please! There's nothing a tired athlete hates more than a coach trying to figure out a plan for the day while they come up with a plan.
8. Use your journal - you have one don't you? - you will find a routine that works, and certain foods or drinks the night before that agree better with you in the morning and leave yu more alert.
9. Drink water - pretty much applies to any situation doesn't it?

People with spinal cord injuries get fit with electrical stimulation rower

This is an inspiring story from the Canadian Broadcasting Corporation (CBC) web site.

Electrical stimulation enables paralyzed rowers use their legs on the Concept II erg. This permits proper muscle growth in the legs. This has important benefits beyond the cosmetics - lower body muscles support the venous system enhancing return blood flow to the heart. Improved return means increased filling pressures which aid heart function.

Rowing Psychology - Competition Preparation

The 30+ minutes from when a crew pushes off until a race begins can be the toughest of all for a coach as the control is handed over to the atheltes and the coach has no ability to step in if unforseen events occur. For athletes as well, there may have been precise preparation for the race itself and perhaps even a scripted warm-up to follow but the mental side of race preparation is often ignored. How well has the mental aspect of your preparation been looked after?

It is important for athletes to be properly prepared mentally so that they have reached the optimal mental state for competition. It is also imperative to have a mental plan in place to deal with unexpected occurrances. Finally, crews need to communicate well as each athelte will have their own best mental preparation for a race.

A related article appeared in the same journal referenced in the previous post titled, "Bring Your Mind to the Line."

Mental Preparation is highly individualized.

The few athletes and coaches I know who do follow a mental preparation plan tend to script it as much as any physical warm-up. They follow either what worked best for them, or what they read in a particular book or article with little attention to the needs of a specific individual or crew.

Research shows that every athlete has their own mental state in which they perform best. One rower may need to focus on who they are racing against and need to be highly energized to race well - like going into battle. Others perform best when they take a more cerebral approach - focsing on technique and their own best race. Still others are best when distracted and relaxed. There are as many approaches to mental preparation as there are rowers.

Having these individual mental states blend well in a crew is a key to the art of coaching. Coaches have their own way of mentally approaching a race and if they don't fit well with a particular athlete it is unlikely that a top performance will ensue. Even if a coach is flexible in her approach, how do they deal with the one or two atheltes whose best mental preparation is at odds with the rest of the crew?

This is doubly difficult if the coach and athlete have yet to work out the best mental preparation strategy. Having younger, or less experienced, athletes recognize their own optimal state is a significant challenge. Without a delibarate approach to this it can take a young rower many years to really learn about themselves.

How can an athlete identify their optimal state?

If you have enough experience to draw on, think back to past strong performances. How were you feeling on the day of a top performance. How did you go about preparing yourself? Do you row best under the direction of a certain coach - perhaps their approach to the race fits you well.

A journal is a valuable tool to have for exercises like this. I would also add that you should consider your optimal state in strong training sessions. How many crews perform well in training but not in competition? Perhaps the rowers’ actual best mental state came about in training. This often means that this athlete needs a mroe relaxed atmosphere in terms of race preparation, or one where they feel in control of all variables.

The reverse can also be true – athletes that "bring it on race day" may actually need to consider their mental plan for training sessions. Perhaps they have made less than optimal use of their training plan because they dd not properly prepare for practice sessions.

Develop a Routine to Attain the Proper Pre-competition Mental State

Should you review the competition before the race or think about your own race, or perhaps even be completely distracted? Many coaches would choose one of these specifically - but for different athletes the correct answer could be any one of them.

Is it useful to have a mental rehearsal of the race? If imagery is part of the plan - consider how that imagery will affect you - there are so many things that can be said in a visualization session that can put an athelte in a variety of mental states.

I would encourage you to consider the mental approach to various situations at the competition site - weather changes, schedule changes, equipment issues, and so on. Having prepared yourself for each of these is key to a successful race.

Consider the Individual

It is important as well to discuss these things between coach and all members of a crew. This can be an important part of early season racing, debriefing and learnign how the various members of a crew need to approach race day before the big competition occurs.

Similarily coaches need to understand that their own preferred aproach to a race may not be the same as some of their atheltes' approaches. A fire and brimstone, marines landing to take an island speech works for some crews - but not for others. How well they can work together may determine the success of a crew on race day.

While the level of excitment and general preparation for individuals matters a great deal - there is important information in the details of the day as well.

For example, Johnny needs his whole crew to be clear that he prefers not to talk if there is a race delay on the water. Jimmy though needs his crew to know he likes to get excited and do a lot of positive self-talk. Some athletes will want to kill extra time with easy paddling and trying to put the race out of their minds. Others will want to do a few more starts or simulations of key parts of the race plan. If these things have been discussed ahead of time and an approach ageed upon then a crew is far more likely to succeed in different situations.

What is key is that you have a plan and that everyone in a crew is a part of that plan. It can make the difference between winning and losing, before the race has even begun.

Rowing Training - Fractal Nature of Periodization

Although it is more about strength training, and not very detailed at that, an article in the NSCA's Performance Training Journal titled Fractal Periodization is interesting. Fractal images are "self-similar" as you magnify them increasingly. In other words, keep zooming in and you see essentially the same image.

The article suggests that this is true of a proper training plan. This is the first such description I have seen of the idea of periodization, but it fits the bill nicely. From a four year cycle, to an annual plan, to a macrocycle and a mesocycle, to an individual workout the alternating periods of rest and work, of balancing the various energy systems in a workout and muscular requirements there really is a self-similar nature to the phases of training.

Does this help your training? Is there a practical nature to it? Perhaps not a great deal, but it does remind you to keep the balance in mind in all facets of your training and planning. Indeed, there are several people now who consider periodization important in all areas of training including nutrition and psychology.

Take a few minutes to ask yourself, how well your training is periodized? What aspects can be better planned?

World Championship Women's 8+ Splits

Not to appear sexist I now provide the 500 m splits from the women's 8+ as well:

Women's 8+

1 USA 01:25.6 01:29.5 01:30.9 01:29.5
2 GER 01:27.5 01:29.9 01:30.5 01:29.4
3 AUS 01:28.2 01:30.0 01:31.5 01:30.6
4 CHN 01:27.9 01:31.5 01:32.0 01:29.6
5 CAN 01:29.5 01:31.8 01:31.8 01:30.2
6 ROM 01:29.3 01:31.7 01:33.4 01:33.8

The women appear far more consistent than the men do, with the possible exceptin of the Romanians - who I expect aren't used to being where they were!

The USA actually had the worst change from first 500 to second 500, although we should note that they probably knew at that point that they had a good lead.

There are many interpretations - what's your take? Hit the link below marked "comment" - please.

World Championship Men's 8+ Splits

This is the 100th post on Rowign Science - a bit of an anniversary!

So what does a true rowing geek do after races? Well, put the results in a spreadsheet and play with them of course!

So - thanks to Worldrowing.com I took the results of the men's 8+ at Eton and decided to see what the 500 m splits were for each crew:

GER 01:18.3 01:21.2 01:21.5 01:21.0
ITA 01:18.6 01:23.4 01:21.6 01:19.7
USA 01:19.2 01:23.0 01:21.8 01:20.2
AUS 01:19.8 01:23.8 01:23.1 01:23.2
GBR 01:20.9 01:24.5 01:24.2 01:22.8
POL 01:20.6 01:23.3 01:25.3 01:24.8

Transition Phase of Training

The World Championships are over, as are all the major summer regattas. It is now time that most athletes should have either just completed, or now be entering a "transition phase" in their training.

A key phase in an annual plan, the transition phase allows for recovery and rejuvination both physically and mentally after peaking for the major competiton of the year. It is the precursor to another general phase when the aerbic base is rebuilt - or one hopes, built upon. Not long ago coaches would suggest a 3-4 week period away from the major sport and while staying active a drop in fitness was expected as athletes take a very significant drop in their training.

Now, it is important to look at the transition phase as another step in a long-term plan. Training plans often look far beyond a year now. Athletes look to improve over a four year (or longer) cycle. The transition phase is important for recovery, but it is important to maintain fitness so that the upcoming phase of building the aerobic base is not a period for making up for lost fitness thanks to a virtual layoff from training for a month.

Coaches now will encourage some brief break after the final competition followed by a period of reduced volume and intesity and perhaps an extra rest day each week - but the maintenance of fitness is important. It is also likely that any highly trained athlete will actually recover better by staying active.

In the coming days we will look at some recommendations for the transition phase and some publicatins with interesting findings that impact this time. For those in schools and colleges about to hit the water again, we will soon get into the beginning of season training and how best to build the aerobic system.

Small Boats Poll Closed

The small boats poll is now closed.

75% feel small boats are the best for technique training.
18% seem to agree, but feel they are unfair in selection.
7% simply feel "big boats rule."

Look for a new poll soon.

Rowing Nutrition Train Low - Compete High

Those familiar with altitude training will have heard of "Live High - Train Low." This is the practice of living at altitude (or simulated altitude), but returning nearer to sea level for training so that training intensity remains high enough.

"Train Low - Compete High" is a play on words, but actually refers to sports nutrition.

Bente Pedersen has done research on single-leg exercise showing that endurance performance benefits from some training sessions in a glycogen-depleted state. In her work Pederson had subjects exercise one leg once daily and the other leg twice every other day. The total amount of training was equal for both legs, but the leg that was trained twice every other day was forced to train in a glycogen-depleted state in that afternoon workout. After several weeks of this, subjects engaged in an endurance test with both legs. Pedersen found that the leg trained twice every other day increased its endurance 90 percent more than the other leg.

Why is this the case? The link might be in a "cytokine" called interleukin-6 (Il-6) - part of the immune system. Pederson is also reasearching this immune factor which is released by skeletal muscle when training as a potential mediator of the health benefits of exercise. These benefits range from increased fat burning, to greater resistance to muscle damage, to improved cognitive function. By "mediator" we mean there is a direct link - exercise causes Il-6 to be released, and it tells the body to adapt.

Interestingly, Pedersen's research has shown that supplementation with drinks containing carbohydrate inhibits the release of Il-6 - so they may also inhibit the training effect.

In practical terms, she said, athletes should do some workouts within a few hours of their previous workout, so that there's not enough time to replenish muscle glycogen stores between workouts. They should also leave their sports drinks at home for some workouts - that is, intentionally under-fuel their muscles during training.

Nonetheless, there is not enough understanding to suggest that an athlete should train glycogen depleted all the time. Evidence suggests that replenished athletes can handle higher training loads (although this may actually mean they NEED more training - see below). Athletes can also train with more intensity when fully replenished. This is probably important and could be somewhat like the "live high train low" concept where it has been shown that the increased training intensity is important enough to return to sea level for training.

Stephen Seiler produced a commentary about this topic. In it he comments that this line of research has led him to question "is part of the reason that modern elite athletes 'need' so much training volume that they eat so well?" In short, all our great nutrition may act counter to the normal training signals our body produces - thus resulting in a need for greater training volumes to produce the same effect.

He points to training systems, periodization and the use of long slow intensity training as having eveloved quite separate from science - and that they may well have an evolutionary explanation.

"Meanwhile, there is plenty of anecdotal evidence that some famous athletes (like Indurain in his day) train intentionally with low carbohydrate availability in preparation for competitions, where they eat lots of carbohydrate. I contend that these behaviours by athletes are Darwinistic in the sense that they represent a selection process towards some optimum achieved over years of trial and error in the elite athlete population."

90 Degree Turns in a Head Race - Reader Question

I received an emailed question from a reader today asking if there is a known fastest method for 90 degree turns in a head race:

I live in Maine and here there is a series of stake races that runs throughout the summer. Also, in the fall the Green Mountain Head, a stake race, attracts some excellent competitors (past and present national team members, etc.). Is there any reliable information about the fastest way to round a stake buoy for a 90 degree turn?

I've been favoring approaching it from and angle and then holding hard with the inside blade. People I've spoken with have found no difference between rowing through the turn with pressure on the outside blade or checking the boat down with the inside blade and, if needed, doing a "river turn."

Many thanks for any thoughts or information you could share on this
topic.


I coached crews at a race that was out-and-back including a 180 degree turn that would be even stronger than the one this reader describes. I have no scientific data to support any particular method, but we felt hard rowing on one side and air shots on the other combined with a wide approach worked best. Having said that, weather conditions greatly affected the turn and this method with the wind in the wrong direction could be suicidal.

I also have heard from a member of a Canadian National Team Women's 8 from many years ago who entered the Head of the Charles (I think it was!) and their coxie used a canoe paddle to back down on one side for a faster turn - since of course ruled illegal - but what a site to see the coxie carrying a paddle down and getting into the boat.

I also imagine that the particualr boat you are in would greatly affect things - obviously a single is far easier to turn than an 8+. Different boat manufacturers have also experiemented with different fins and rudders for such races. I saw a Dirigo fin/rudder combination on a Hudson 8+ once for just this reason.

So this is a question to readers - What is the fastest way to turn 90+ degrees in a race? Of course I mean head race - in a 2K race the answer is: "catch a crab!"

Please add comments or email me your answers.

Rowing Takes Heart - Elite Rower's Hearts May Appear Pathologic

If you have a strong interest in Sport Science you may well have heard a story about someone you know going to the doctor and inciting some degree of panic when tested. One colleague of mine was almost given an injection of adreniline when he went to hosital for something and his (perfectly normal) heart rate was measured in the low 30s. In another case, a clinical biochem professor showed his blood data to his class and pointed out how to an untrained doctor it would look as though he had a heart attack - he had finished third in the Boston Marathon.

Another measure that can be similar with athletes and unhealthy patients is heart size and thickness. In a failing heart you see enlargement - lengthened muscles contract stronger so it is an attempt to preserve cardiac stroke volume. Of course athletes hearts enlarge to pump more blood where it is needed also.

This article from back in 1991 in the New England Journal of Medicine sought to use imaging to separate the fit from the sick heart. They looked at 947 elite athletes from various sports looking at the thickness of the left ventrical wall. When it is greater than 13 mm it is considered to be a diagnosis of hypertrophic cardiomyopathy. Interestingly, only 16 of 947 athletes would have been seen as over 13 mm - 15 of them ROWERS or CANOEISTS.

If you are a highly trained rower and you have to see the cardiologist this is worth knowing. For most of us it is just an interesting bit of trivia...I suppose it is true that rowing takes heart!

Related to the last post the EIS has several medical resources for athletes and coaches. It stood out as one reader inquired recently as to my thoughts about Bird Flu. While I don't feel personally qualified to answer that question there is a bird flu update on the site.

This site looks well worth checking out for those of you who like to leave no stone unturned in your preparation.

Resources Available that might be interesting:

Flu Vaccine
Bird Flu
Jet Lag
Hay Fever
Autologous Blood Injections - "Blood Doping" - don't do it, but I know several of you might be interested in reading more as it has been in the press recently.

English Institute of Sport Biomenchanics for Rowing

Dr. Valery Kleshnev who interviewed with Rowing Science, is featured in this piece on the English Institute of Sport site about preparing British Rowers for the World Championships.

There isn't a great deal of detail in the piece, but you certainly get a feeling for the intensity of the British effort. Dr. Kleshnev describes a number of people involved in the effort and the importance technology plays in providing athletes and coaches with biomechanical feedback.

Vitamins - You May Not Need Them While Training Hard

Charmichael Training Systems publish a nutrition newsletter monthly that has some interesting information in it.

This month's newsletter writes that when you are training hard a multivitamin might not be needed - the opposite of what many would assume:

If you're like most people, you probably assume that you need a supplement-store's worth of extra vitamins and minerals when you're burning through so many calories in a day. But here's what's missing from this assumption: you're also eating a heck of a lot more food when you train hard, and if you're downing quality fuel from a variety of healthy sources such as fruits, vegetables, dairy, whole grains, lean meats, and fish, then you're already taking in high doses of vital vitamins and minerals.

Check out the newsletter for more information on this and other topics.
