Kayak analogy

Another way they are analogous -- I think they use many of the same muscles. I went on a four-day kayak trip a few years ago, and while I was a little sore, I really didn't have that much trouble adjusting to kayaking all day for four days in a row. (And yes, it is possible to kayak straight!) (Kayak trip was in British Columbia... saw orcas from the kayak... highly recommended!!)

I don't know much about kayak paddling but isn't there a difference in the relationship of the long axis of your body and the direction of travel with freestyle? If you rotate your torso in kayaking this helps push the blade backwards and so propels the boat forwards. If you twist around your torso in freestyle this doesn't generate motion in the direction of travel. I'm not very good on anatomy so perhaps there is some gearing which allows circular motion around the long axis to be translated into motion along the long axis (cf. the transmission in a car) but this isn't immediately obvious.

Matt Mann always said kayaking was a great way to train for swimming. At Buck Dawson and Rosemary Matt's daughter swim camps Kayaking was a major activity for their clients. Old Ideas are really advanced technology.

In fact there is no way to transfer the torque and keep the kayak going straight when paddling on one side not true, depends on the boat and the skill/balance of the paddler.

We do have rudders the other hand and arm. The other two extremeties the legs. The toes also come into the realm of things.

You may be right about paddling a kayak being more about twisting, I have limited experience with kayaking and none of it is recent. Still, I don't think the motion is limited to twisting around the long axis, there is also a simultaneous shifting of one shoulder upwards and forward and the other arm backwards and down. Interesting that in kayaking you twist the torso rather than rotating the body, necessitated by the fact that you are sitting. If you take out the rotation around the long axis you are left alternating shrugging one shoulder upward while dropping the other shoulder downward and then vice versa. If you start with this alternating shrugging of the shoulders and then add in moving the shoulder forward as you raise it, and the other shoulder backward as you drop it you'll have the motion I'm thinking of. Or you can move each shoulder in a circle (with one shoulder at the top when the other is at the bottom). All of the above is described for a person in a vertical position, for a horizontal swimming position up becomes forward, forward becomes downward, down becomes backward and backward becomes upward. In swimming I think there is a point just after the catch where the shoulder of the pulling arm is low (due to rotation around the long axis) and extended forward, while the recovering arm is raised (due to rotation around the long axis) and . As the recovering arm moves forward there is a point where it feels like the whole torso is moving in unison. To me it feels like the recovering arm is helping draw the other shoulder and arm backward. Hmmm. Let's try a simpler explanation: stand up with one arm raised in the catch position, the other arm just starting the recovery. As you raise the recovering arm in a recovery motion there is a point where if you lock your shoulders together the act of lifting the one arm will cause the other arm to come down. Note that if you want to you can shrug the shoulder of the recovering arm up and down without causing the other arm to move just by keeping your back muscles relaxed. But if you tense your back muscles the pulling shoulder will drop as the recovering shoulder is raised. I don't know how to better describe how you lock the shoulders together but it is mentioned in the Popov video so it isn't a figment of my imagination. Even doing a simple twisting of the upper torso there appears to be a set of muscles that can lock them relative to one another rather than simply moving them simultaneously. It is also interesting that the lock seems to be stronger if the upper arm (when standing) is raised with the elbow rotated outwards and the shoulder extended far enough that you feel a stretch in the lats, and, interestingly it also seems to be stronger if the shoulders are rotated around the long axis so the pulling arm is lower (forward if you are standing) and the recovering arm is higher (backward if standing). I see that Elaine has posted while I've been writing this, it's good to hear that a kayaker agrees with the analogy!

I have kayked, but I do not kayak. I just remember going in a circle when paddling on one side (kayak without a rudder) and when paddling on both sides, it fishtails because it can't roll or have a compensating kick like swimmers to prevent fishtailing. I don't see the analogy. Perhaps paddling out prone on a surfboard is more analagous. Perhaps Lindsay means the kind with a rudder? don't know.

Not once have I remotely thought "gee kayaking is similar to swimming". In fact there is no way to transfer the torque and keep the kayak going straight when paddling on one side (unless it has a rudder), yet we can swim one arm drills without a problem. I think they are a great tool for following swimmers though. Do you kayak? And, if you do, have you surfed or raced? Try it and you will see what I mean...

I am curious as to whether other people have the same feel of a kayaking motion? Yes! :agree: When I lived in San Diego, I surfed by kayak and competed in two 5 mile races. And, when I wasn't kayaking, I trained on my K1 Ergo, the same kayak trainer used by the Australian and American Olympic teams. So, I can confirm that your analogy works. Now, having said that, I am a breaststroker. But, I am getting some part-time coaching on my freestyle. And, the more I learn and tweak my stroke, the more it feels like kayaking! :D
