Posos highballs

Another day up at Posos, this time doing some scrubbing. Cleaned up an awesome highball block that turned out to climb very well. Did about 6 lines, another 4 or 5 to get back to do.

Drew on the best line - an as yet unnamed V4 - on the highball block

Ape Index

In a  change from the usual programming, an idle friday thought post on the ubiquitous measure for natural climbing aptitude - the Ape Index. In case you aren't aware of this measurement, it is the ratio of your height to your arm length, and for climbing purposes, the larger the ratio, the more like an ape you can classify yourself. Which has clear implications in climbing of course. In fact, it is hard to think of ways in which it could be negative. And when sharing beta on reachy problems, really you should be talking to people of similar wingspan, not height.

The V Man - probably wouldn't be pulling down V hard with a classically neutral Ape Index

Not just in rock climbing, swimmers and boxers claim a competitive advantage too. But I am a scientist - I demand data!

Michael Phelps (swimmer) + 3"
Sonny Liston (boxer) + 11.5"
Manute Bol (very very tall basketball player) + 23"
Iker Casillas (goalkeeper) +4"
Daniel Woods +4"


More climbers ape indices here.

Alright... we need a lot more data than that. Luckily for a lazy writer like me, the wikipedia article on Ape Index highlights a few studies with mixed conclusions. One study says its statistically relevant, another says otherwise. But many people would point to studies on climbers in general being lacking in scientific merit and having too many complex variables to draw meaningful results about any inquiry.

So going back to the original point, are there any times when a negative ape index could be a positive? Well, short arms are more flexible, more easily to bend. It is hard to find an elite climber with a negative or neutral ape index, but it is worth noting that Nalle Hukkataival and Adam Ondra have relatively short arms (+1/2" and +1" respectively).

Negatives of a positive ape index? Well there are certainly mainly negatives of being tall - problems with a strict starting point can become scrunchy, compression can be hard, legs can just get in the way. But those are mostly problems with legs, not arms. There can be situations where it is mechanically disadvantageous, e.g. on bench press, as it forces the lifter through a wider range of motion, and will put greater stress on tendons in situations like this, which could occur climbing. Anecdotes relate tendon problems to abnormally long limbs, but I haven't got time to go data mining (beyond 10 seconds on Google) to find if there is any science that supports that or not.

Deviations from the "ideal" are markers for disease however, e.g. Marfan syndrome (a genetic disorder that creates long limbs to height ratio). Human leg length, sitting height and their proportions, or the sitting height ratio, among others are associated with epidemiological risk for overweight, coronary heart disease, diabetes, liver dysfunction and certain cancers (Ref).

So what is ideal? Well that depends a great deal according to ethnic and racial type, not to mention nutrition whilst growing up (those who grew up under rationing in Western Europe in the post-war period were measurably shorter than their offspring). I could not find any accurate data as to what the average persons arm span / height is, and whether the Vitruvian Man ideal of a neutral ape index is actually realized by the average healthy adult male. However, I did find this paper on a Serbian population which found a positive ape index for men of 2.82±4.89 cm that was statistically significant whilst for female subjects they found a negative index of -2.15±4.68 cm that was statistically insignificant (ref). They found that men had a larger ape index (statistically significant).

And what about evolution? We came from apes, which clearly have huge ape indices (actually, I am blanking on data for arm spans for mammals too). We lost some of this as we became Homo Erectus and evolved for different climates - a person who has genes that were designed for a cold climate will tend to have shorter bulkier limbs which will allow for greater heat retention.

Well I hope you enjoyed this little thought adventure with me, even if we didn't actually discover any meaningful answers hopefully I raised a few interesting questions. Do you think your ape index is a help or a hindrance?

Finally, let us not forget - as we get into our old age and start shrinking, our ape index is likely to marginally increase. So best save some of those super reachy projects for our golden years....

Another day in the NM 'alpine'

Spent a brief but fun day up at Ortega - New Mexico's new 'alpine' bouldering playground. I have been a little absent from the development spree that has been happening up there all summer at the hands of the Los Alamos and Socorro crews. Summers not my favourite time to try hard outside, I prefer to train and focus on the king of the seasons - Fall! I picked up a copy of The Rock Climbers Training Manual, which is the new go-to guide specifically for sending hard shit outside. Its incredibly dense and detailed and unlike other books focuses on transferring the hard-won indoor training gains to outdoors projects. I have a tick list for NM and hueco up on my fridge right now, and getting fired up for sending them when the temps drop.

Anyway, Ortega! Peck and the crew showed me a new area, just a tier below the ridge that Ive walked near but never seen - yet another amazing zone with huge potential for highballs. We put up a **** V2 Giant Steps - see photo below - that was just unbelievably perfect (no cleaning, no loose rock, just a perfect line sitting there - would be a classic in bishop, yosemite, hueco, anywhere).. but the arete to the left of here (cant see it in photo) is the real line.... Also repeated Peck's Thugalicious, a V5 compression arete that climbs in the classic Ortega style.

I do keep asking myself how much interest there will ever be in Ortega. Every time I go up there, Im like.. this drive kinda sucks... then the approach kinda sucks... no trails... no one will ever do this. Then we get there and we're running around like kids in a candy store, finding an almost neverending stream of amazing rock and amazing problems all piled on top of each other... then it seems like this is an incredibly special area, that actually has a distinctive style that stays with you. A mix of burly sloper compression, technical footwork, reachy moves between sublime blankness, bomber micro crimps and glorious, miraculous jug hauls.

At the end of the day, nobody really cares if Ortega becomes a "destination". We're having so much fun up there!

Vallecitos

The village of Vallecitos is just a little further north of La Madera and has another amazing roadside quartzite outcrop. Can't wait til Fall to check it out!

Summer bowlderin': Posos and Ortega

It may be hot and stormy here in NM but we're still trying to get out on new rock. Two spots in particular are high enough in elevation (8500-9000') to just about escape the heat - Posos and Ortega, both made of the wonderful ortega quartzite. Posos has been developed by William Penner, Tom Ellis and Masumi Shibata, so really just a re-discovery for us, Ortega is all new.

Posos is actually a real gem of an area, small but quality, a nice mix of high and low-ball, steep & beefy as well as vert & techy. Mostly moderates, but theres an incredible V7, and the sit is an even more incredible project that surely will go, but likely in the V12 range. I think this line could honestly be one of the best lines in NM. The rock here is pretty extraordinary, crazy knobbly but smooth texture like limestone, and stained orange like rocklands or something!

Really weird rock!


Beautiful wall!
