Plantarflexion

As a physician, I was happy to see the use of the word "dorsiflexion" in "Double Pole Follow Up". It is an unambiguous term, unlike "bend at ankle". However, you seem to have it confused with "plantarflexion". Dorsiflexion is what happens when you point you toes away from your head by flexing your calf muscles. Plantarflexion is what happens when you point your toes towards your head by flexing your anterior tibialis muscle. The photograph of Kikkan Randall shows her ankle in plantarflexion.

Double Pole a Marathon?

I am planning to double pole a ski marathon.  What is the best ski selection for such an endeavor? 

Would I choose a stiff classic ski or go with a skate ski? Thank you.

To double pole an entire marathon race you will want a top level classic ski, flexed on the stiff side. Top level classic ski have flexible tip which allow them to snake around curves in the classic track without scrubbing speed. A skate ski is not fast when gliding on a curvy classic track. Top level skis will also have the ability to maintain their glide when you are up on your toes for a good double pole. Recreational classical skis are designed for easy kick so they generally lose their speed when you are skiing with an aggressive double pole.

Good Luck, Andy at SkiPost

Pole Length

Ski Post,

It appears to me over the past few years that the average pole length for classic skiing has increased. This seems true for both World Cup as well as the average ski racer. I have always thought that classic poles should align anywhere from your arm pit to the top of your shoulder when in a standing position. What is the current recommended pole length?

If the average pole length is getting longer, what is the reason?

Hello,

Classic poles length has increased on the World Cup because World Cup skiers have increased their upper body strength and there are more sprint races and circuit races with short hills rather than long sustained climbs. Pole length has also increased with loppet racers and juniors because, for better or worse, they try and emulate world cup skiers. But I believe many people are using classic and skate poles that are too long.

• In most cases, this will for adults result in classic poles that reach the center of the shoulder bone. For skate the pole will reach around your mouth. This is measured in shops with normal shoes on.
•  
• Do advanced skiers use taller poles than beginners?

For shorter races such as sprint; definitely yes. They can use up to 5-7.5 cm longer poles than recommended. We have also seen a trend that professional skiers in general has increased their pole lengths the last decade. The reason is most likely stronger upper bodies for professional skiers these days, and shorter tracks with fewer longer climbs. There are of course individual differences, but in general professional now has increased their norm by 2.5 cm both for classic and skating.

• Does upperbody strength change this? See answer above.
• Does technical ability change this?

Not really, but skiing with longer poles than recommended requires a good technique

• Why do classical skiers use shorter poles than skaters?

In skating, bigger movements and greater speed allows you to have longer poles.

• How is a ski pole length measured? For most brands poles the length is measured form the tip (spike) of the pole to the top of the pole (less the building height of the locking cap/wedge).

Additional; Insight from 

Trond Nystad head Coach for Team Norway,

The rule of thumb is to find a classic pole that fits underneath your armpit and a skate pole that is about 10cm longer than your classic pole.  A flatter course will generally call for a little longer pole.  Some, but not all, use a pole that is about 2.5 cm longer if the course is flat. This would be the pole to use in a loppet race as well if one is just double poling.  Since double poling a long race is relatively new, it is important to first try this in training and then decide on what length pole to use...there is not hard and fast rule here.  In general world cup skiers are stronger and have better technique, hence they tend to use a little longer poles than a normal citizen racer but just a little.

Follow the main rule and then try a little longer and shorter to find what fits you the best.  Most ski centers have rental poles that one can test before one goes out to buy expensive poles.  If in doubt it is better to buy the poles a little longer as it is easy to cut down poles later....impossible to make them longer  .. But this is not rocket science ...long poles is for sure not good as then people just hang behind the poles.  important to have a pole where one can use the upper body strength and be "over" the pole.  We follow the KISS principle...keep it simple stupid....have people try and then use what feels the best.

Trond

As with all aspects of ski technique it is not possible to discuss and isolated issue because all of the movements in skiing are integrated. Modifications in one area can have an effect in other areas and the same applies to the poling movements and pole length. Having said that, I think the typical pole length recommendation of 83% and 90% of individual body height is a good range to maintain good balance between all movement patterns.  I use poles at 85% for classic and 90% for skating. These lengths feel about right for me at this time and I would caution against going more than a two to two an d a half centimeter longer or shorter as it may have both technical and physical impacts on other aspects of ski technique.

There are multiple factors to consider when determining pole length. The primary considerations should include the whole body muscle activation patterns, the ski terrain, individual strength, technique, and the body height and position. There is most certainly a range of pole length that may work for an individual. But there is also a length that will be too long or too short that will limit the ability of the poling forces to produce power. Also remember, too long or too short a pole length can alter body position and technique in a way that may alter muscle activation patterns and other aspects of technique.

There are many interesting studies on poling forces and pole length that analyze muscle EMG activity and horizontal, propulsive and vertical poling forces. These studies are too complex to summarize in a short response but they can be captured in what we have experienced and feel on skis.  Both the vertical and horizontal reactive forces play a role in the poling movements. So I believe there are good reasons to maintain a nearly vertical pole plant to load the poles and carry the body weight.  Long poles may require a greater angle at pole plant!  When skating first came along there was a significant push to use far longer poles thinking it would increase poling and gliding time. This did increase both the poling and glide time but did not increase the power output or the speed.

I believe we need to think in terms of the efficient production of power, fast force production, from the poling movements. A longer pole may make you feel strong in the poling movements but there is a big difference between exerting force on the poles and producing power efficiently. To increase speed we need to think about decreasing poling time. In short, the longer the poles, the longer the poling time.
