We’ve already written a few posts looking at BMI and climbing across a few different data sets, and now comes the final chapter! We’ve combined every single ascent logged on 8a.nu with every profile to see if there’s a correlation between BMI and hardest grade climbed in the last 2 years. After filtering off climbers without a height or weight, […]
In our previous post we looked at user ratings for ascents in the 8a.nu top 100 female/sport/boulder database. We missed an important detail though…when an ascent is logged a default rating of 0 stars is given (thanks to NP for the spot!) This complicates things because if we look at the breakdown of ratings by grade… For […]
In previous posts where we’ve looked at data from 8a.nu it’s always been from climbers in the top 100 rankings (female/sport/boulder). This gives us a nice snapshot of ‘elite’ climbers, but what about the rest of the climbers on the site? We’re starting to look at more users, and as a little teaser we’ve put […]
[Update 13/10/2017: user NP pointed out an interesting issue with the below article in the comments. We’ve done a follow up in Are Hard Climbs Better? Part 2] Have you ever noticed how if you flip open your favourite guidebook all the hardest climbs in the area will tend to get more stars than the easier […]
We’ve already looked at BMI in climbing a couple of times, first in our own data and secondly looking at an overview of some numbers from 8a.nu. Today we’re going to have a look at the 8a.nu numbers in a little more detail. In particular, we’re interested in seeing if there is a correlation between climbing grade and […]
We use maximal finger strength (as measured by a 5 sec. hang on a 20mm Lattice Edge) as a key data point in our performance profiling and when combined with all the results from our testing it gives a good indicator of climbing potential. However, we have wondered for some time whether forcing a particular […]
It is well known that climbing (both bouldering and sport climbing) is a sport that is affected by power to weight ratios. The biggest factor that bodyweight affects is the percentage of bodyweight that we’re able to hang on a climbing hold – simply put, if you reduce body fat and retain lean muscle mass you’ll […]
Body weight in climbing is a hot topic of discussion and has been for a long time. It’s widely acknowledged that carefully controlled body fat composition can help in some situations, but is lighter always better? We have looked at this in the past but it’s always good to have more data, so we’ve teamed up with […]
The big grade of 9c has officially landed! Adam Ondra has succeeded on his Flatanger Project Hard, undoubtedly the pinnacle of his climbing career to date. The 9c grade is obviously a big number – almost too big for some of us to comprehend – but how big is it? What does this benchmark on […]
Every now and then we bump in to interesting little titbits in our data: milestone grades are one of these! In theory we would expect people’s best grades to follow some sort of distribution but it appears the population of climbers “who train” (i.e. the ones who come to see us!) gravitate towards classic milestone grades. Our route […]
