Been thinkin’ about ratio recently. “Ratio” usually means “the amount of time you spend on the drive, compared to the amount of time you spend on the recovery,” and it should be small – that is, it should feel like you spend more time on the recovery than on the drive, at least at moderate-to-low pressures and ratings. “Ratio” is also used to refer to a sensation of having enough time to do what you need to on the recovery, without feeling rushed or hurried.
But of course I think there’s more to it than that. (I’m pretty reliable like that.) In addition to the drive:recovery ratio, I actually like to think about the ratio of time spent getting into the body angle position to time spent on the recovery as a whole. And I like to think about the ratio of time on the first part of the slide vs time on the second part of the slide. I’ll discuss each of these in turn, then speculate as to their source.
Just to tack things down a little and make things (slightly) simpler, let’s imagine a low stroke rating – say, 22 or so. Things change as the rating rises, as we know.
I like to get into the body angle position pretty fast on the recovery. I think of handle speed into the body as determining handle speed away after the release. Actually, pressure and/or rating determine handle speed into the release, which then determines handle speed away. And handle speed away just after the release determines how fast I have to get to body angle. All of this is written with the proviso that the hands lead the body. Just as the hands finished off the drive, they begin the recovery. The amount of time it takes me to get to body angle on the recovery is shorter than the amount of time it takes me on the slide. I like to think that the quicker I get to body angle (without exaggerating things) the more time I have to roll into the front end.
Then there’s the slide itself. Because I want as little momentum going in to the front end as possible, I want my slide speed to end up being very slow, so I have very little deceleration to do before I stop. Momentum, of course, is mass x velocity. I can’t change my mass on the recovery; I only have velocity to play around with as I adjust my rowing. So I imagine my seat as rolling uphill on the second part of the recovery, coasting gently to a stop as my wheels come to a halt. That’s where the sense of ratio within the slide comes from: The first part of the slide happens faster than the second half. This has a lot of benefits – less force needed to slow myself down, so less sternward push needed when my blades aren’t in the water yet; more time (mentally, if nothing else) to feel for blade placement and lock-on. All this makes it feel as though the time I spend going from body-angle to half-slide, say, is shorter than the time I spend going from half-slide to the catch.
Here’s a little graphic illustrating the stroke, which might help. The top is the recovery; the bottom is the drive.
There are two ways to think of this diagram: On the recovery, if the time it takes to get to hands-away takes a time unit of 1, the time it takes to get to body angle will be another 2 units, then yet another 2 units to half slide. Finally, it takes another 3 units to get to the catch, for a total of 8 time units on the recovery. Compare that to the 4 time units on the drive: 2 for the leg drive and 2 for the swing. Or you can think of the drive as having a beat of two – first beat is legs down, second beat is swing body over. In that same cadence, give yourself a count of four or even five on the recovery.
But where does all this come from? Why should it be that way?
I think it comes from handle speed. I imagine, though I’m not positive, that a constant angular velocity (i.e., speed around the arcs) of the handles results in the lowest momentum for your body weight coming in to the front end. I’m not that great at physics, having been a humanities major, so I’ll have to leave it to someone else to do the equations. (If they come up with a different result, I’ll have to rethink the theory, ack!).
Next, you have to imagine that, while the handles go around those arcs at a constant speed, they don’t have the same speed along the length of the hull as they go from release to catch. Instead, think about them this way: If the handles move toward or away from the long axis of the boat, they aren’t going to be moving along the long axis of the boat as much. Imagine the handles’ shadow on the seat deck of the boat. That shadow moves fastest along the deck when the handles are perpendicular to the boat and slowest when they start to spread apart at the catch.
Feeling this is possibly the trickiest of all. It might be relatively easy to think of getting fast hands away, but getting into the body angle position lickety-split is less intuitive and hard to square with the idea of not rushing. That’s because, for many people, “not rushing” means “slow movements”. So achieving the kind of movement I’m talking about on the recovery might require a re-evaluation of what you think “not rushing” is.
I remember when I first started learning this. I didn’t know what was going on, but I knew there was something difficult about following my friend Anne W., who was really good. She was faster than me, so I tried to make my stroke match hers exactly. At first, I made sure my slide started at the same time as hers. But I kept noticing that when I did that, I’d only get to about 3/4 or 7/8 slide before she was at the catch and putting her oar in the water. So I’d recalibrate on the next stroke and try to get my oar in the water at the same time as she did. But then I found I had to start my slide before she started hers, and I felt like that was rushing her. I finally managed to get it right by not thinking about it too hard but just absorbing her rhythm, and only after that did I start to understand and be able to articulate what was going on. The feeling of being assertive, shall we say, with my slide speed was novel and a bit unsettling. It really called for careful use of my hamstrings on the recovery in order to consciously regulate my slide speed.
What drills are there to help yourself learn this rhythm?
First just try rolling up and back on your slide, with your blades flat on the water. Try to get the feeling of rolling uphill and alighting to a stop, not falling downhill and landing at the bottom. You’ll need to actively use your hamstrings to control and adjust your speed. You can make the speed back as fast as you want; your blades won’t be in the water, so it won’t matter much.
This one I think I’ve listed before, but bears repeating. Use the drive cadence to determine the recovery cadence:
1. Take a few strokes to get up and going at a 20-22 spm. Then count “one… two” to yourself on the drive, where “one” is the leg drive and “two” is the swing. Memorize that beat.
2. Now, on the recovery, you’ll count “one… two… three… four” to the same beat. Here, “one” is hands-away, “two” is body angle, “three” is half-slide, and “four” is blades in the water. Better yet, have someone else count it for you – someone in a launch or on the dock as you go by.
If you really want to push yourself, try a 5-count on the recovery to the same beat: hands-away = “one”, body angle = “two”, half-slide = “three”, three-quarter-slide = “four”, and blades in the water is now “five”.
You can also try bringing the rating down by 2 beats every minute or so, staying at a constant pressure, but keeping the time it takes you to get to body angle the same, and letting the slide portion of the recovery stretch to accommodate the lower rating. This is hard, though; you’ll be tempted to achieve the lower rating by pausing at body angle, which is the opposite of what you want. Instead, think of making a micro-pause (like a flash photograph) at half-slide and then at three-quarter-slide as you row. You could even imagine that time itself stretches and slows down as you get closer to the catch.
Let me know how it goes!
