What part of the stroke/stroke cycle does it refer to

The catch.

What does it mean/refer to

The position your body is in at the catch – hips behind the shoulders, shins vertical, etc. –  is called “full compression”. Over-compression is when you go beyond this point and your knees end up over your toes (instead of in line with your ankles). Shorter rowers (and novices) have a tendency to over-compress at the catch as a way to get more reach.

Relevant calls

I don’t make a lot of calls for this on the water because I can’t see when it’s happening (unlike other things I can’t “see” where I can pretty closely guess what’s going on based on the bladework). Plus, over-compressing on the water is a more rare occurrence than over-compressing on the ergs so even when I’m coaching it’s not something I see that often (at this point though that might be more of a factor of who I’m coaching than anything else though).

When we’re on the ergs most of what I’ll say will be simple stuff like “too far…”, “stop a little shorter…”, etc. if I see them coming too far up the slide and then once they’re stopping closer to full-compression (rather than going past it) then I’ll have them pause at the catch and tell them to think about what this position feels like and if we’re beside any mirrors I’ll have them look over to see what their bodies look like, where their slide is in relation to their heels, the angles their shins are at, etc. If you have less-experienced rowers who haven’t fully figured out where full slide/compression is yet then utilizing mirrors/video while on the ergs during the winter is the best way for them to figure this out. (You can also use the tape trick to help with this – figure out where full slide is and then put tape on the slide so that the rower feels the slide hit it if they compress too far.)

Sometimes over-compressing can be a byproduct of not getting the bodies set soon enough so if I see that happening then I’ll address that first (read the post linked below for more on that) and usually the over-compressing (which has them sitting straight up, heels right up against their butt, and hips directly under the shoulders) corrects itself.

What to look for

This is what correct full compression looks like…

…and this is what over-compression looks like (note the positioning of her shins at the catch)…

In some cases on the water, usually at the beginning of the season or if the rowers are switching seats a lot, you might find that the foot stretchers (if they’re set too far towards bow) need to be adjusted to prevent them from over-compressing. This shouldn’t be the first thing you jump to though to fix the issue unless it’s completely obvious that it’s the cause and not the rower’s technique.

Effect(s) on the boat

The effects of over-compressing obviously have an effect on the boat but they more drastically (and obviously) impact the individual’s stroke than they do the entire boat. The biggest impact is on their power output because it puts you in a weak position when you go to initiate the leg drive; instead of relying on the quads and glutes to help you generate power as you drive off the footboards, you’re now relying on the smaller muscles of your calves as you start the drive. If you’re trying to get more reach you might get an extra inch or two but in the end you’re sacrificing some of your power to do so.

Related posts/questions

Hi! So I recently started rowing not to long ago, as I just did two weeks of long skinny boat camp. But as I was rowing I kept getting told not to over compress at the catch. Also to relax my shoulders. I am short, only 4’11 and I talked to the coach about coxing(my sister is a captain) in high school and he wants me to row first. Do you have any tips I can take from the rowing? Also how not to over compress at the catch? Thanks! I love your blog!

Ergs Q&A Technique

Question of the Day

By

Question about the foot plates on the ergs – what number do you find it’s best to keep them on? Is there a standard it’s “supposed to” be at or is it best for each girl to change them for herself? What do those numbers even mean?

Where your feet are placed on the erg make a huge difference in your technique and power output. When I explain this to novices, I tell them to think about what their feet look like when they go up on their toes or for girls, what it feels like when you’re wearing heels. Where your foot bends below your toes (on the balls of your feet), that’s where you want the strap to be. This allows for the most natural movement as you come up to the catch. If the strap is above that (over your toes), it’s not helping you out at all and can actually lead to you over-compressing (meaning your knees are in front of your ankles, which is an entirely separate issue). Over-compressing means that your legs won’t activate immediately at the catch and you’ll end up becoming fatigued faster due working harder than you have to.  You always want your toes to be in contact with the foot stretchers, and having the strap too high (meaning the number is set too low) prevents that.

On the flip side, having the number too high will put the strap down over the center of your foot (closer to your ankle), which is extremely uncomfortable. I don’t even know how people can row like that and not assume it’s wrong. This prevents your heels from coming up as you move on the recovery (at the very least it doesn’t let them come up enough) and doesn’t allow you to get fully compressed at the catch, which means your stroke is short and you’re not generating as much power as you otherwise would. It can also lead to a lot of lunging, because if you can’t get all the way up the slide you might compensate by trying to reach farther than you normally would to increase the amount of length you’re getting.

The shorter you are, the higher the number will be. The taller you are, the lower the number. I’ve seen some guys who row with it on 1 or 0 with no problems. It’s both a personal preference and … not. The strap has to be on a certain part of your foot in order for your stroke to be correct but the number that the stretchers are at is different for everyone. There is no “standard” so each rower should set their feet themselves just like they would in the boat.

I’ve never really looked into it so I’m not positive what the numbers mean but it might be how many inches of shoe is left over once you’ve adjusted it … but that’s a total guess that could be completely wrong.

Q&A Rowing Technique

Question of the Day

By

I have this bad habit of shortening up my stroke and basically just not compressing enough. I never really notice when I start to do it, I feel as if I’m at full slide but my coach tells me that I’m getting short. How do I force myself to lengthen out when I hardly notice I’m doing it? I’ve also been told it might be flexibility, if so what on earth do I stretch to help that problem?

Row2k actually posted a hack yesterday that I think could help you out. They wrote this with the use of an erg in mind but I think you could definitely try doing this in the boat if you used a piece of tape or something on the tracks. Basically what you do is you take a bungee cord or a piece of tape and wrap it around the erg at the point where your body should be fully compressed when at the catch. Then when you row, you’ll know if you’re hitting that spot because the slide will either stop completely (if you’re using a bungee) or you’ll feel the slide hit a “speed bump” (if you use tape). Based on those feelings, you can train yourself to inherently recognize where your full compression should be.

Another trick you can do for when you’re in the boat is take a regular drinking straw and tape it to the side of the boat to mark where your catch should be. When you’re fully compressed and reaching out towards your rigger, you should be able to touch the straw with your finger tips. If you can’t, you’re not going far enough up the slide. If you’re hands go past it, you’re going too far (or didn’t tape it to the right spot).

Like you said, your flexibility could be an issue as well. Where it’s lacking is most likely in your low back down through your hamstrings, so those, in addition to your IT band (which runs along the side of your upper leg), would be the muscles you’d want to focus on. Guys typically have tighter hamstrings than girls, so if you’re a guy, that could be contributing to the problem (girls can have tight hamstrings too, but it’s more common in guys).
