Re: do we need a heart rate monitor for sure while rowing?

Putting in my usual plug for the Polar OH1 HRM. This is a simple, reasonably priced BT-LE based monitor that goes on your forearm or bicep. I used chest straps for years and was skeptical that something on my arm would be reliable rowing. But I tested it and it works very reliably. Other great thing...

Re: HR data in iOS from ErgData

Probably not what you want to hear, but I couldn't figure out a good way to do this. I ended up using an apple watch to get data into the Health app and then use the HR monitor connected to the erg or RIM in the boat and saving that data separately (on rowsandall). I use health to basically just kee...

Re: Improving my time in a single skull

Hi, A couple of thoughts for you. 1. Ergs are calibrated so that the splits are similar to what you'd see in a 4+, which are faster than a 1x, so you should expect to be slower. 2. To get an idea of how fast you "could be", there is a calculator online where you can plug in your height, weight and 2...

Re: Age / Height / 2k results

Here's the analysis... https://analytics.rowsandall.com/2018/12/08/why-are-rowers-tall/ Two conclusions: 1. The trend is clear that taller rowers are faster, a rule of thumb is a second off the split for every inch of height for men, closer to 1/2 sec for women. 2. There is huge variation from perso...

Re: Age / Height / 2k results

Because I banged out the plots in 5 minutes. I just wanted to get a taste for the data.

I'll redo the analysis when I have a bit higher response rate. Right now, I've got about 160 responses.

Re: Age / Height / 2k results

I took a quick look at the results so far. I have about 150 responses. Here's a quick plot of the 2k times versus height for just the male rowers. https://quantifiedrowing.files.wordpress.com/2018/12/foo.png Here it is for female rowers https://quantifiedrowing.files.wordpress.com/2018/12/foo1.png I...

Re: Age / Height / 2k results

I analyzed all concept2 ranked results for 15 ranking seasons (2003-2018). I looked at the decline in performance relative to the results in the "younger than 30" group. If you look at all rowers and just put it on a plot, here's what it looks like. http://analytics.rowsandall.com/wp-content/uploads...

Age / Height / 2k results

Hi, Rowers often talk about the relationship between age, weight, height and rowing performance. Last winter I did an extensive analysis of how age effected rowing performance, but there is very little data on how weight and height effect things. I would like to ask a favor of all you rowers out the...

Re: Aerobic Base training

One other note. For me, a 55 year old, open weight dude. I have tried a range of different training approaches including a version of the sweet spot training (Rojabo). I achieved my best results with an adaptation of the Pete Plan where I did the hard sessions per the plan, but instead of the "stead...

Re: Aerobic Base training

HI Bob, The most accurate way to determine AeT is with lactate testing. AeT is the wattage at which you can maintain your lactate level below a certain threshold. There are a bunch of issues with this. First, it's a pain to measure lactate. You need to get a meter and test strips, learn how to use t...

Re: Am I LWT or HWT?

I actually did an analysis of this using all the ranking data going back for about 15 years. The data shifts around a bit, and there is certainly a larger group of open weight athletes, but lightweights seem to decline a bit less than heavies up to 60, but then they decline a bit more in the 60-70 r...
