Matching potential time in the water when rowing
|
When putting a crew together, every athlete must achieve good length through the water. In this video, Lachlan demonstrates how matching potential time in the water can be valuable when choosing to work on rigging or technique.

So today i want to have a look at a masters crew that i've been coaching and specifically we're going to look at the length of people's strokes and what we can do to change that with some simple rigging changes so let's have a look you can see here the stroke person is really struggling to get into a good position their feet are feet compared to their seat height is way too high for their level of flexibility and so we need to change that by either raising the seat or dropping the feet probably dropping the feet we'll have a look when we get back in
so if we have a look at at three seat they're getting into a good catch position so that's pretty good not looking at technique at this stage just positioning the boat same with two seat two seat is getting into a pretty good position this is towards the end of the session so it's really quite a good position for that if we have a look at bow though see if that was a bad stroke but in bow seat we're really looking at those shins not being vertical so let's have a look at the next stroke
yeah so those shins really need to be vertical and a bit of that could be packing up a little bit could be feet to seat height so we just want to increase that distance so dropping the feet a little or raising the seat probably dropping the feet or using a seat pad to to raise the height up a little bit so because bow and stroke are rowing a little bit shorter bow seat is quite a lot taller than the others but let's have a little bit of a look and see how much time they're actually spending in the water so let's have a look and so strokes got their blade in the water there let's put a timer on it
so the timer says the time the blade starts to come out probably looking at 0.53 of a second let's have a look at three seat so let's have a look at three seat so the blades going into the water buried there start the timer
so three seats looking at point six six
now it's a little bit more you can see here the handles are right in the body whereas the handles aren't riding at the body so drawing when three seat draws through a bit more um they'll find that they're in the water for a lot longer likewise if you go back to the catch
if the blade was placed here instead of here that would increase it a lot so we're not really looking at we're looking at the potential time in the water when we're trying to assess length we're not looking at the actual time in the water so when you've got the video you can slow it down so let's have a look at three seat again so the blade coming into the catch the blade could be in the water there so this is where we'd aim to have the blade in the water at that point
so all the way through to the finish we'll be looking at the finish being a little bit further back so a bit further a bit further probably about here holding the blade in the water so it's almost a second so let's have a look now so a second that's probably pretty good length let's have a look again at stroke seat so the blades coming getting in the water relatively quick but let's just say the ideal spot for stroke to get the blade in the water would be here it's a bit more snappy coming through and that's right in the body so it's starting to come out there but let's say that's as far as i could go
so we're looking at a potential stroke length for what the boat's set up now the stroke seat been about 0.8 of a second and for three seat being about a second so that's a really large difference between potential and you can see that because three seat has got such a longer stroke they're actively trying to slow down the placement of the blade in the water whether they know it or not and also tapping out a little bit quicker than they should be at the finish you imagine you need a lot of power to be able to get a longer stroke done in a shorter amount of time and it's just just not possible
so what we really want to do we don't want to be lengthening three seats stroke at all that they've got a good length down the slide we really want to be increasing the length of the the slide length and the reach out of the catch of the stroke seat just to match the three seats so it's important to know where your set point should be where you want to get other people to move to and what rigging changes you'll do so when we head out next time we'll make sure that stroke either has a couple of seat pads to increase the seat height or we'll look at decreasing the feet height and probably probably a little bit of both so in summary it's important to know where you're going with your rowing stroke what potential stroke length you've got technique is off also very important getting the blade in and out at the right time but you want to make sure that every athlete has the same potential to be able to get full length and when the boat's rigged like it is in this case it's impossible for stroke seat to get the adequate length and that makes it very hard for the rest of the crew to follow them just because the boat isn't quite set up for that individual
so if we have a look at at three seat they're getting into a good catch position so that's pretty good not looking at technique at this stage just positioning the boat same with two seat two seat is getting into a pretty good position this is towards the end of the session so it's really quite a good position for that if we have a look at bow though see if that was a bad stroke but in bow seat we're really looking at those shins not being vertical so let's have a look at the next stroke
