Rowing Equipment: The Cox Box

noreply@blogger.com (Alan Thomas) — Mon, 03 May 2010 05:20:00 +0000

The key pieces of rowing equipment include far more than a boat and oars today.

Long ago a coxswain might have had a simple cone to focus his or her voice and they might talk into the bottom of the boat in hopes that it would carry their voice to the rest of the crew. Today as the coach on the water the coxwain is an integral part of any crew and the cox box and speakers that ensure precise communications with the rowers is no longer a nicety - it is an essential piece of equipment.

Cox boxes give stroke rate, stroke count and time as well to help the coxswain guide the crew in the perfect execution of a race plan. This of course with its most basic function of voice amplification carrying the coxie's voice to 2-3 or more speakers placed in the boat near the crew.

Nielsen Kellerman have produced the almost de facto standard - so de facto that their name "cox box" is the standard like Kleenex now means tissue to all or rollerblade means in-line skate.

It would be hard for anyone to dethrone the leading company - so many clubs have multiple units and training coxies to use a different brand or even to risk trying another brand with a relatively expensive purchase.

Still, others are trying to bring their game.

NK units don't give boat velocity and supply limited feedback to the coach after a workout or race. Some clubs combine the cox box with another piece of equipment like a speedcoach to get velocity (there is no consensus if these units really are accurate with bigger boats).

A company like Coxmate is worth a look. They produce several units - the most sophisticated being the SCT which handles the basic functions but adds velocity with a micro-impeller that is significantly smaller than the NK unit or even a GPS function. It also has a PC link for coach analysis.

in2Rowing made a unit packed with features, including GPS but their web site now says they are shut down "indefinitely."

Rowing Equipment – Erg Training Basics

noreply@blogger.com (Alan Thomas) — Fri, 23 Apr 2010 02:29:00 +0000

You went out and bought a nice shiny new ergometer. Your rowing machine has been a dream for a while and now you have it at home.

Now what?

Well, do us all a favour and get some technique help, watch a video or better yet get some instruction – health clubs are full of often perfectly fit folks with the most embarrassing technique. I’d explain it here but you need something visual. Learn a bit and you’ll enjoy your erg. Ignore my advice and you’ll destroy your back, get little from the workout and look, frankly, like an idiot.

‘nuff said.

This isn’t jogging folks. You don’t get on the erg and shuffle along with little effort. The rowing machine is the ultimate full-body burn-a-tonne-of-calories exercise device. It also isn’t sprinting – the first few strokes will seem easy, especially with health-club technique – but it isn’t. Slow down Charlie – if you sprint your workout will be over in a minute or two at best.

No, you need to learn to settle into a hard puling 18-22 strokes a minute rowing workout. Pull hard, then relax. Runners like to work hard all the time. Rowers like to pull and then enjoy a small break as they recover for the next stroke. Enjoy that time!

So – sort out your ergometer technique. Learn the basics of pacing and how to handle the low stroke rates of 18-22. Now enjoy the thrill of a long endurance workout.

Your first bout on a rowing machine will of course depend on your current level of fitness, but let me suggest that you try to maintain your pace for 10 minutes without stopping. Sounds easy, but if you are learning then it won’t be (see info on pacing and technique).

Get that down and extend your time on the machine. 3 x 10 minutes is a good aim or 2 X 20 minutes. The variations are endless - just keep your heart rate up for an extended period of time. No so much that your lungs are searing and your heart wants to blow out your chest wall. Just enough to make talking tough, but not impossible.

Later, we’ll give you some tips for maintaining your rowing machine and for changing up your workouts.

Rowing Equipment III: Oars

noreply@blogger.com (Alan Thomas) — Sun, 11 Apr 2010 06:17:00 +0000

Along with boats, oars are the most basic and important piece of rowing equipment.

Today all oars are constructed from a mixture of carbon fiber and fiberglass, permitting the construction of a lightweight oar with the ability to control important properties, notably the stiffness of the oar.

Sculling oars come in a variety of lengths from approximately 280cm - 295cm or more, with custom options available from leading manufacturers. Sweep oars range from 370cm to 380cm or more, again with custom lengths as well. Today, most oars come with the ability to adjust the length to a degree, typically at the handle.

The "blade" often refers to the part that is placed in the water to propel the boat. While some clubs will invariably still have the older Macon style of blade in their stock the "hatchet" style of blade is used be virtually all competitive crews now. The hatchet blade offers a greater amount of surface area, and it is used with shorter oars as a result. Its center of balance is toward the top of the oar, rather than the middle as in macon oars. Most rowers find them easier to grip the water without technical mistakes. The shaft of the oar is connected to the blade assymetrically - higher up on the blade which minimizes the amount of shaft in the water (which contributes to drag), as well as maximizing the surface area of the balde that can be submerged.

The exact size and shape of the hatchet varies between companies, and individual companies even offer a variety of shapes.

The path of the oar through the water during a stroke is not uniform. The forces applied as a result change throughout the stroke and rowers are also more effective in applying force early and through the mid part of the stroke than in the later part of the stroke. Manufacturers dedicate considerable time and energy to research as the shape of the blade will change how effective it is in each phase of he stroke.

Oar Manufactuers:

Concept II - USA Concept II, maker of the most-used rowing ergometer, also provides the majority of oars used in North America.

Croker Oars of Australia have significant market penetration in North America and around the world.

Empacher - the German boat builder also makes their own oars.

Rowing Ergometer Race Strategy

noreply@blogger.com (Alan Thomas) — Wed, 07 Apr 2010 22:01:00 +0000

Thanks to reader Daniel Carvalho of the Galit Club in Portugal sent along a spreadsheet that helps with erg race pacing.

Ergometer Strategy Spreadsheet

He included the following explanation:

The file named Ergometer (did not know what else to call it...) allows us to actually see some interesting details:

The dependence of 500m split (mm:ss,0) and Power (W) (decreasing the 500m split from 2'02'' to 2'01'' is not the same as decreasing from 01'38'' to 01'37'' - Ok, most of us know that. But usually coaches tend to say that heavyweights should be x seconds per 500m faster than lightweights. That is not a reasonable demand since 4s/500m (e.g.) at conversational pace is not the same as 4s/500m when you are pulling hard)
The most economical power (and 500m split) for any distance is 44W (03'19,6''). I am still surprised by this conclusion (see Power - Split - Calories folder, cells in green) (I used the C2 formulas. Hopefully the calculations are correct.)
Suppose you want to know how fast (and how powerfull) was James Reichert when we pulled 9127m in 30minutes (1994). Simply type 9172 in a grey cell signalling 30min in the C2 Ranking workouts folder and you wiil find out that the average split was 01:38,1/500m and 370,5W (which is what I pulled in my latest 2k erg test... hehehe)

The file named Ergometer - Training zones according 2000m Erg Test is pretty simple.
You may want to rename the tags correspondent to x% of the 2000m average power.
Other than that seems a good way for dosing your workouts.

Rowing Equipment I: Ergometers

noreply@blogger.com (Alan Thomas) — Mon, 05 Apr 2010 21:13:00 +0000

The most basic piece of land based rowing equipment is the ergometer.

Concept II has the standard machine and if you want to ascend the ranks of rowers and compete at a significant level, you'll need to become an expert on the rowing machine.

Coaches use them in crew selection, the wise ones only as one of many tools, the less informed make decisions based entirely on erg times.

The greatest criticism of the erg - aside from pain and boredom! - would be the fact that they don't perfectly simulate on water technique. Sports scientists will tell you that fitness is sport specific and while an ergometer is a useful training tool, it will never replace or properly duplicate the feel and training on water in a real boat.

Rowperfect produces a rowing machine that is said to better replicate the feel on water, unfortunately the concept II machine is standard in so many boathouses that the Rowperfect has not made substantial inroads in this important segment of the rowing equipment market.

Concept II produces an addition piece of equipment - the slide. Ergs are places on concept II slides which enable the machine to move rather than being fixed to the ground. This makes the feel much more like actually being in a boat. Unfortunately, it is a significant additional cost and clubs are often already on stretched budgets.

On the other hand, for the individual or family wanting to add some rowing gear to their home, the cost of an ergometer is not cheap, but at $900 is far, far more affordable than buying a boat and oars at ten times that cost - and of course most people can find a bit of ground to place a rowing machine on, while few have access to water or boat storage.

If you are looking to add an ergometer to your home, then consider going to one of the many indoor rowing competitions each year. Hosts must provide dozens of new rowing machines for the racing and sell them off at significant discounts after the event is completed. You'll need to be in touch early - likely the fall - and reserve your erg as they sell off quickly.

Another great benefit of the rowing machine is the ability to work on fitness when your technique as a novice rower can be limiting you ability to get in a great workout on the water. As you learn you can supplement your on water skill development with erg training on land - where you can work as hard as you want after some very basic skills have been developed.

At the same time, having an ergometer with well-placed mirrors or even a video camera enable the rower to gain insight into their technique that can't be had on the water.

The basic rowing ergometer technique will be explored in a future post.

Rowing Science Changes

noreply@blogger.com (Alan Thomas) — Mon, 05 Apr 2010 20:48:00 +0000

As longterm readers will notice there hasn't been a lot published here in a while. We're not in a position to continue significant content on the science of rowing, so in an attempt to continue adding content, we're going to broaden the focus of the site.

We'll now include more information on rowing equipment, rowing machines, and the basics of rowing - in addition to the occasional return to our roots of rowing science.

The Effect of Wind Resistance on Boat Speed

noreply@blogger.com (Alan Thomas) — Fri, 22 Jan 2010 06:09:00 +0000

Early squaring can have a very significant effect on racing speed.

Also in the December 29 issue of the Rowing Biomechanics Newsletter Dr. Kleshnev reports on the effect of wind resistance on boat speed.

How significant can wind be?

"5 m/s head wind makes singles 17.4% slower and eights 12.2% slower, tail wind of the same speed makes singles 7.5% faster and eights 5.1% faster."

He briefly compares to World Championship results and suggests the research may somewhat overestimate the effect.

Perhaps most interesting is the significant effect of feathering and squaring of the blade - something we all know who have been in the boat, but perhaps not the extent:

"If the blade squared early at the middle of recovery, a crew can lose up to 10 s over 2k race at calm conditions and up to 30 s at head wind 5 m/s."

Influence of Water Temperature on Boat Speed

noreply@blogger.com (Alan Thomas) — Fri, 22 Jan 2010 06:04:00 +0000

In the December 29 edition of the Rowing Biomechanics Newsletter Dr. Kleshnev reports on the effect of water temperature on boat speed - based on research out of East Germany in the 70s.

"...boat speeds decrease by 1.3% (~4s over 2k), when the water temperature drops from 20o C down to 5o C. If the water gets warmer, up to 30o, then the boat goes 0.6% faster (~1.8s over 2k). The power trend fits very well to the experimental data (R2 = 0.99)."

The reason is the change in the properties of water which changes frictional resistance.

Cold Weather - Safe for Rowers

noreply@blogger.com (Alan Thomas) — Sat, 19 Jan 2008 07:35:00 +0000

Rowers are notorious for never letting up, even in extreme weather. It might be an early morning row in below freezing temperatures, or a cross-training run where the water has frozen over but rowers keep going. Still, some are concerned about the effect on the body of exercise in such extreme temperatures.

A recent position paper from the American College of Sports Medicine, reviewed in the New York Times, indicates that exercise in cold weather - no matter how cold - is safe, even for those with exercise induced asthma.

Two key points:

1. The air is warmed to body temperature before entering your lungs - no matter how cold it is outside.

2. Those who suffer from exercise induced asthma need not fear the cold - or at least can now know that it is actually the dry air that accompanies cold that causes them stress. The effect in dry warm air is just the same.

The author suggests that wearing a balaclava will help by becoming moist and thus moistening the air before it enters the lungs. It is also important that asthma sufferers take precautions in dry warm weather,

Study confirms importance of protein suppressing appetite in a diet

noreply@blogger.com (Alan Thomas) — Fri, 18 Jan 2008 19:40:00 +0000

A recent study, as reported in the Globe and Mail today, provides some confirmation of what many rowers have long felt - protein in a diet suppresses appetite better than fats or carbohydrates. In fact, the researchers were looking at the hormone ghrelin , secreted by the stomach, which is an appetite stimulant. Drinks containing more protein did a better job of suppressing ghrelin than fats, and while carbohydrates initially did a good job, later on they were quite poor. This of course will be familiar with anyone who is quickly satisfied by a high carb feed, only to be extremely hungry shortly thereafter.

This obviously bears some resemblance to the effect seen in high glycemic index foods, where insulin reacts to high blood sugar after high carbohydrate foods, often overreacting and actually lowering blood sugar.

Master's (and others?) - How taking beta-blockers affects exercise

noreply@blogger.com (Alan Thomas) — Mon, 14 Jan 2008 22:27:00 +0000

An article from the Mayo Clinic on beta-blockers and exercise will be of interest to some readers. Beta blockers are prescribed to lower blood pressure and have the effect of lowering heart rate. As such normal exercise heart rates cannot be achieved. If this is the case for you, check out the article.

Strength Training

noreply@blogger.com (Alan Thomas) — Mon, 14 Jan 2008 08:55:00 +0000

I just stumbled upon an interesting article on strength training for rowing you might be interested in.

I must say though that I have always been a proponent of specificity of training and the usefulness of on-water or on the erg strength training - you can read more here. This needs to be balanced with an athletes need for variety, and for changes in the training methods to prevent injury. Heavy load rowing without adequate preparation or experience can be a recipe for injury.

Winter Nutrition and Hydration

noreply@blogger.com (Alan Thomas) — Mon, 14 Jan 2008 08:26:00 +0000

Many athletes mistakenly believe that their hydration requirements decrease in the colder winter months. Not so! Of course, if you are properly clothed for training sessions then you will still be producing excess body heat and sweating as in any hard workout. In many places, the winter air is drier and your bodies natural moistening of the air as it takes it in results in further water losses via respiration.

What's more, your thirst response is diminished in the winter - so your drive to drink is less.

Athletes and coaches...you need to consciously choose to hydrate during winter trainign sessions for optimal performance.

New Rowing Biomechanics Newsletters

noreply@blogger.com (Alan Thomas) — Tue, 13 Mar 2007 22:50:00 +0000

Two new Rowing Biomechanics Newsletters have been released of late.

January 2007 Edition is a comment on Mechanical Modelling in Rowing. It is a more general comment although it makes reference to a talk at the British Coaching Conference 2007:

The next talk, “Physics of rowing”, was one on which we cannot fail to comment. The presenter had developed quite an interesting computer model of rowing and some gadgets. However, instead of explaining the model, he presented a mixture of trivial things...

It is perhaps most interesting that he points out that most models use variation in boat speed as a major reason for energy losses in rowing. He notes:

The main verbal expression of this erroneous theory is: “do not disturb (stop) the run of the boat at catch”. The consequences of this are a soft ineffective catch, and early opening the trunk and slow force increase, which we found is very important for effective drive (RBN 2004/01-2).

He also discusses a front loaded drive vs. a finish loaded drive, which the models suggest is better, but biomechanically does not make as much sense.

In the February Edition Dr. Kleshnev responds to comments about spread/span discussed in an earlier newsletter. This includes remarks by well known biomechanist Volkere Nolte and by Einar Gjessing of Norway, creator of the “Ergorow”.

American College of Sports Medicine Position Stands

noreply@blogger.com (Alan Thomas) — Fri, 09 Mar 2007 23:59:00 +0000

An excellent source of information is the American College of Sports Medicine who are a professional organization representing not just sports doctors, but all professionals in the field of sport science from exercise physiologists, to biomechanists, nutritionists, psycologists and more.

Their "position statements" are professional recommendations based on research literature. All these statements are available in PDF form on their website.

Of particular interest are two released recently. On March 1st they released a paper on "Exertional Heat Illness during Training and Competition" and February 1 they released one titled "Exercise and Fluid Replacement." These summaries should represent the most up to date information in the field and should be near the top of the reading list for all coaches as well as interested athletes.

While the information is fairly technical in nature and not something you would read in an aticle off the magazine stand, you can be sure it is current and reported by experts.

Rowing Coaching Education - Rowperfect Resources

noreply@blogger.com (Alan Thomas) — Thu, 22 Feb 2007 20:17:00 +0000

Thanks to Rebecca Caroe of Rowperfect (and her own blog) who sent me an email with references to several of their resources related to recent posts here. I would encourage you to go over and have a look. In the near future I may get a chance to expand on some of these resources but for now, a brief summary and an encouragement to take a look.

Resources from several Rowperfect seminars is provided including:

Information on Seat Racing by Duncan Holland

This relates to my posting of an excel sheet for use with a pair matrix, and our poll on selection.

He includes some important points:

It is a big assumption that a pair can select an eight!
Don't repeatedly test young people on the erg.
Fit the test to the training (and events) at the time - longer in winter, shorter in summer.
Seat racing assumes athletes have comparable fitness, skill, honesty and motivation.

Although just points from slides, his layout of how and why to use fours, rather than pairs of eights is well worth a read if you plan on doing any seat racing.

Training to Perform presented by Paul Thompson

British Rowing Technique presented by Rosie Mayglothling

Athlete Testing Protocols presented by Martin McElroy

This one relates to our most recent post on peak power as a valid sub-maximal test for evaluating athletes and athletes progress. This includes protocols for:

Sub Maximal
Strength Power
Step Test
Anaerobic Capacity
1000m
500m

There are some great resources there and excellent graphics to help demonstrate the testing protocol.

Peak Rowing Power Predicts 2000 m Erg Performance

noreply@blogger.com (Alan Thomas) — Tue, 20 Feb 2007 19:21:00 +0000

The latest issue of The Rowing News contains an excellent article by Ed McNeely describing peak power and how to measure it on the erg. McNeely's article raises some intriguing points, but it also fails to mention one important factor - body mass - and how it affects this measure.

Peak Power is essentially the highest wattage obtained when setting the drag at 200 over 10 strokes. Others use slightly different protocols, but they all measure essentially the same thing. Refer to McNeely's article for a complete description of how to use it in your training.

McNeely mentions that several studies confirm that peak power is one of the best predictors of 2000 m erg preformance. This would seem somewhat counterintuitive. Rowing is 80% aerobic, while peak power is a measure of anaerobic performance - and mostly the ATP-CP system that works for only a few seconds. Yet McNeely is right.

One study found the correllation between peak power and 2000 m erg performance at r=0.92 p<0.0001.There are others that have found essentially the same result.

This is not isolated to rowing, and also holds for other aerobic sports, even ones where the athlete must carry his or her weight even more than in rowing. Similar findings have been reported for 15 years in cycling. this article from South Africa by several authors including Tim Noakes, who recently was a keynote speaker at the Rowing Canada Coaches Conference found a strong correlation between peak power and both VO2 MAX and a 20 km cycling time trial. Interestingly another cycling study found that peak power increased from 864W to 940W or almost 9% after ingesting a controlled amount of caffeine.

In rowing, researchers have seen a 1.2% improvement in 2 k erg time and a 2.7% increase in mean power with caffeine ingestion. The same researchers in another study saw similar results with most of the improvement coming in the first 500 m - perhaps suggesting the effect was largely anaerobic, as is peak power.

Implications for You - and What McNeely Missed.

Peak Power is simple - perhaps for many even fun - to measure. Athletes don't seel the same pressure, or pain, that they do in a 2K erg test, yet the feedback it gives may be largely the same. We won't eliminate the need for 2K tests, but this may be a simle way to monitor training more regularily.

Train for power - McNeely describes how in his article and there are several other ways to include power training in your plan.

What he missed - the article I cited notes that the strong correlation between peak power and 2k erg times is true only when you consider lightweights and heavyweights separately so be cautious in how you use it to compare athletes. It would be better used to compare an individual athlete's progress in
training.

Don't forget our recent post on weight adjusting erg scores. First - the same formula cannot be used to adjust a measure of peak power. Second, well - weight matters. In fact the article that found the strong correlation with peak power also reported a significant correlation between body mass and 2 km erg performance!

Finally, remember that this information is derrived from studies on elite athletes. MCNeely points out that it may be a good measure because elite rowers are all so comparable aerobically and anaerobic measures may then be an important determining factor. I seriously doubt that this is true for club, masters or junior rowers.

That said, in my coaching experience it can be a useful measure with elite junior athletes, although whether peak power has the same correlation to 2K time in juniors I can't say. It would be interesting to have some coaches take both measures on their next round of testing and report the results here to our readers!

More Excel Examples for Rowing Coaches - Time Trials and Pair Matix Seat Racing

noreply@blogger.com (Alan Thomas) — Mon, 19 Feb 2007 19:32:00 +0000

Since the last excel file I posted on doing weight adjusted erg scores proved to be our most read post to date I decided to post a couple of more example sheets for you. They are not necessarily ready to be used at a local event tomorrow, but they provide good examples of going beyond basic excel functionality to enhance your coaching. Athletes may well be interested too if only to gain a better understanding of some things coaches often talk about.

While I liked using ZoHo for posting the last online spreadsheet it didn't perfectly recreate my work in Excel and the next two examples are more complex. So, I have posted them to a free file sharing site called "4Shared.com." Please go there and download your own copies of these two examples. As always, feedback is most welcomed and if you find them useful I would love to hear from you. I am also happy to make some changes if you need anything different but aren't up to speed with Excel.

Pair Matrix.xls

This file allows for easy calculations used in a traditional "pair matrix" for seat racing. It is limited to 4 port rowers and 4 starboard rowers, but simply putting in the name of the athletes and the times for each trial will rank each athlete. Scroll to the right of the matrix to see the ordered ranking of athletes. Of course not everyone feels that crew selection in a pair is the best way to select a larger crew, but that is for another post.

Time Trial.xls

This is for using Excel to calculate times in a time trial or head race. It is far more detailed than a simple calculation of (finish time - start time) as it reports perecentages of gold standards and percentages of winning times, and it also ranks crews on a separate worksheet without the need for doing any sorting. It's probably well suited for a coach to use with several crews in his/her club, but would need a bit of work to run a whole head race. I hope that it does provide some useful examples.

Interesting Study on Fight in the Dog

noreply@blogger.com (Alan Thomas) — Mon, 19 Feb 2007 17:48:00 +0000

Thanks to JW Burk over at Fight in the Dog for this interesting link. It suggests that ancient rowers of Greek Triemes may have been as fit, or fitter than today's elite rowers. I expect there are a lot of holes you could poke in the assumptions and informtation sources used in the article but it still makes fun reading.
