The Sharma scream

It’s funny how quickly and readily fashions spread through climbing. Lycra, slang terms like ‘Send it dude!’ and... 

Screaming.

In the eighties, when the French really were the kings of ‘French Style’ climbing, as sport climbing was then known, their ideal was to climb like a ballet dancer, with effortless panache in the movements, a totally straight face and not a sound coming from your lips. 

Now, thanks to films such as the Dosage series, the fashion tends to be to slap your way up that granite boulder like a wild animal screaming at the top of your voice.

The obvious question is, which is best (for performance, not looking cool). The answer comes in two parts. Firstly, somewhere in between is best. Secondly, where you should be on the continuum between straight faced ballet dancer and screaming bull terrier depends largely on who you are.

Chris Sharma, being the most famous (and possibly loudest) exponent of the psyche scream has made screaming while climbing a talking point, and I’m sure, more fashionable. He does it, so it must be good, right? Well, listen to Chris talking off the rock, and you’ll see he is a pretty chilled out type of guy. When asked about his screaming, he says it helps him raise the necessary level of aggression to unleash his full power on the holds. 

When I observe others taking up this deliberately aggressive climbing style, it sometimes has poor results - poor timing, overly basic movements, not much weight on the feet and inefficient use of energy on a route/problem.

What’s going on here? In a nutshell, for those who are inherently calm and make clear, calculated and efficient movement decisions in their climbing, some extra psyching up can help them get more out of their physical capability, but just on the hardest moves. In other words, in small doses.

For those who can very easily deliver a lot of focused aggression in their climbing, more psyching will yield little more power output but incur a big drop in efficiency of movement.

The great skill of climbing is to be able to switch from moment to moment between screaming to get maximum power on a very powerful, but technically basic move, and calm focus the next instant to perfectly aim for a tiny foot of handhold.

The climber that most influenced me was Fred Nicole with a quote (from memory of a magazine article) that “it’s not so much the level of strength but the timing of it” Fred went on to explain that the climber that could use is strength at the exactly correct moment would be the best.

Influences - It can go either way actually

In my recent coachwise articles published in Scottish Mountaineer (and online here) I’ve talked a lot about the power of influences on your training, in terms of training choices, discipline, goal setting and level of effort.

My message here in a nutshell was that if you are surrounded by the psyched, the skilled and the hard working, you are more likely to be those things too.

Just listening to a section in Evan’s podcast about business (it’s episode 28th May if you want to download it from the Bottom Line site) reminded me not only of the strength of this effect, but also a good decision of the flip side - bad influences.

Evan’s guests were discussing positivity of attitude in general. The perspectives were generally that positivity is really good as an attribute and an influence. But problems raised were firstly that positivity must be bound by realism, and secondly that disappointments from failures can be hard to cope with sometimes.

Taking the realism thing first - This is where positivity coming from both inside yourself, and from outside sources is crucial to work within the bounds of reality. The kind of positivity that you see in talented youngsters spurred on by positive influences with a bias (friends and especially parents) often get ahead of themselves and later suffer big motivational setbacks following failures.

Positive outside influences with no bias are like gold dust. These sources tend to be encouraging by example, not just by positive reinforcement of you. They also solve the second problem of learning that it’s ok to fail, again and again, that it’s part of sporting or any success, and it’s possible to shrug it off and respond in the right way.

But talking of realism, I think it’s fair enough to say that negative influences will almost always outnumber positive for most people, in most communities. Of course the battle is to  hold the negative at arms length where possible, and soak up as much of the positive as you can. But sometimes it can actually seem like an advantage to operate in relative isolation.

I have noticed, living away from a substantial city-based climbing scene for a couple of years, and absorbing most of my media through highly customizable (web based) sources, that I have more power to reach positive (if distant) influences in my climbing, while being insulated from the many negative influences out there. I think it’s been good for my climbing.

Evan’s guests talked about a major advantage for young business people was sometimes ignorance of all the hurdles ahead. There is some truth in this.

There is much to this subject - the influences we have from other people, our ability to exercise self control, our exposure and sensitivity to feedback of different kinds as we train for our sport. All are important and affect our ability to get the most out of ourselves.

Just a thought as I listed to Evan’s (excellent) podcast while painting some doors late at night...

Onsight confidence - a holy grail?

Justin asks:

“I regularly find the difference between success and failure on a route can be distilled down to state of mind on the day - the confident relaxed approach to just go for it that sees you through the crux before you know what's happening as opposed to the doubt, hesitation etc that can lead to panic, missing obvious sequences, placing too much gear then falling off. Working a route removes the unknown which makes it very easy to stay composed - but do you have any tips for attaining / maintaining the right frame of mind for a hard onsight attempt?”

There are several strategies to help create a relaxed confident frame of mind for an onsight, but here are my top five:

Don’t get too built up - Often, getting excited about an onsight you’ve been looking forward to for ages can pile on a lot of unnecessary pressure. It’s not so bad in sport climbing because if you fall off a nice 7b, there are a million others in the sea, but in trad it can be worse if there are not so many rotes of that style/grade that lend themselves onsighting. So, the challenge tends to be to not think too much about specific routes you want to onsight and more about a general level. When you think about specific routes, it’s all too easy to let failure scenarios take over your imagination and destroy your composure on the actual attempt. It’s usually better to think about the result (success/failure on a specific route) as little as possible, and just to focus on how you are climbing generally. It might be better for some people to not prepare too thoroughly for the day of the attempt - anything that increases the sense of occasion might place more subconscious pressure on you. My tactic has always been to convince myself I don’t care whether I fail on the route at all and just go for broke. I just focus on climbing the next move or section well and nothing more. Hopefully you find yourself at the top?!

Think of past successes. The trouble with onsighting is it’s impossible to visualise the moves based on actual experience of doing them (obviously you have to when reading the route from the ground). So all you have to go on is past successes. So it pays to play back the feelings of confidence and good movement you had in previous onsights that went well. The more similar the route to wheat you are aiming to onsight next, the better.

Get familiarity. Your best onsights will tend to happen during a run of a lot of similar climbing. In redpointing it’s often not too important to have done a lot of similar routes recently. But for onsighting, the more you are immersed in every aspect of the routine of onsight days and climbing, the less the ‘shock of the new’ will make you worry about success/failure and the more you will just centre your focus on the immediate job in hand - the next move.

Get trust in your gear - There is no easy way to do it, falling onto gear, especially unanticipated falls will give you the largest single jumps in climbing confidence you’ll ever have. So a good tactic is to try ‘bold but safe’ routes where there tends to be harder climbing and a bit run out, but above very good gear. If you try a lot of them near your limit, you’ll experience that sickening feeling of realising you are about to fall and there’s nothing you can do about it. But it’s only sickening at first. Once you have experienced it many times, you’ll be able to recognise it for what it is and not let it destroy your focus on fighting through that last move to the resting ledge. It will also help you for future routes to accept that a gear placement is totally reliable and you’ll beat the tendency to stop right in the middle of the crux in a fruitless search for more gear when it’s unnecessary.

Break routes down - The more you look at routes and break them up mentally into a series of short hurdles between rests/gear, the less you’ll feel the choking sense of taking on something huge. Start off with the aim ‘just to get to the first gear’ or the crux or whatever the natural break in the route is.

The common theme is all of these points is that the conditions for confidence are created in advance, sometimes a long way in advance. It’s nearly impossible to magic confidence out of panic in the moment of an onsight. Only well grounded tendency to have confidence over the long term will be able to bring your focus back from the brink. Start now.

New series of climbing improvement articles

I have been working on a series of introductory articles for the Mountaineering Council of Scotland’s magazine and site. They deal with general concepts of improvement in climbing so hopefully they will be thought provoking for beginners and those who’ve been climbing for many years. I’ve just finished the second one, with more on the way soon. The articles are here.

Brendan raised an interesting point after reading the section ‘The truth about famous climbers’. In this I’m talking about the dynamics of the returns you get from effort put in. It turns out, it’s not as simple as you might think. This is his point:

Hi Dave,

cheers for writing those excellent MCoS training articles, I wish they'd be available a few years ago when I started climbing, would have saved me loads of wasted effort.

 

I have a query - you say in the last section about top climbers that they go the extra move/problem/route each time.

However, I've heard a lot of people at the wall recently say you should 'finish strong', I suppose so that you shouldn't keep going after you're too tired to give your all as it will take longer to recover for the next session.

How does this resolve with your advice in your article? I suppose it depends on how soon your next session is going to be?

It’s a good point! And it doesn’t have a totally simple answer.

What I’m trying to put across in my article is that a little extra effort can often yield a lot of extra return by taking you over the threshold between enough to maintain the same level and stimulating the body to improve. This is an issue of training volume. The objective is to achieve the highest possible training volume that is sustainable over time (i.e. You can recover mostly from, in time for the next session).

Most climbers shouldn’t concern themselves with ‘stopping strong’ because they weren’t trying hard enough in the first place, or they have days of rest in between sessions. 

Another smaller proportion of climbers might have problems with being fresh enough for the next session, but the problem is not with training too hard, it’s with not recovering hard enough! i.e. They are too stressed, don’t eat well, sleep enough or add more things to recover from like a night on the sauce.

An even smaller proportion of climbers will need to take care not to overdo it on each session because they are really going for it with both their effort level and volume and taking care over their recovery as well as training. What should they do?

It’s a fine balance to tread between injury and improvement. Stopping strong will mean different things to different climbers. In general you should train as hard as you can and feel worked after your sessions. There is a subtle but perfectly tangible line turning point in the session when quality attempts on climbs becomes a rapidly declining thrashing session. When the elbows come out on the first moves and your hands melt off jugs that were easy to hang an hour ago, time to go home, eat a nice meal and sleep well. Come back tomorrow with the pedal on the floor again.

side note: the physiology of this is about using up the 'fuel tank' of muscle glycogen. It happens that recovery of the glycogen store takes much longer if the store is completely exhausted. You know this has happened when you are slapping your way up F6a gasping, when you were fine on F7b an hour before. So overall training load is higher if you stop just before you drain the tank altogether.

How many days on?

I get many emails from climbers asking how many days on they can have and whether they can do some supplementary training on the ‘rest days’ like fingerboarding.

Of course, my reply is ‘it depends!’ Most people can see clearly that an elite level athlete can tolerate many more sessions per unit time than a beginner or someone carrying a complication such as an injury. So there is no standard unit of time to rest between training sessions except this one:

Rest as long as it takes your body to recover from the specific stress you have placed on it.

This rule has two messages; the first is that you can only use the messages coming from your body to decide how much training it can handle. If your performance is going down from session to session, while you are training more than usual and feeling tired and sore, then maybe it is too much. If nothing is happening (no improvement but no soreness or temporary fatigue, then maybe you could experiment with more.

The other part is to keep in mind that climbing training requires variety in the venues, modes, intensities etc. of the training stimulus. Exposing yourself to this variety is not just important for training all the elements, it also allows you to spread the stress on the body across different muscle groups and energy systems and hence maximise the overall training load.

So, what does that mean in practice? If you go to the same wall and do the same problems, week in, week out, You will only manage a small proportion of your potential maximum training load without getting plateau and then injury.

But if you mix up your training in any way you can, you will be able to handle much more days on and longer sessions. Even subtle variety will help here – a different board, problems set by a different person, different hold manufacturers etc. But don’t use this to neglect the big sources of variety – routes instead of always bouldering (or vice versa), different rock types, different training venues, different training partners and many more…

Review: Climbing-Training for Peak Performance by Clyde Soles

I was interested to pick up a copy of this American climbing training manual. Out of the training for climbing manuals I’ve reviewed on this site so far (most of them), none have managed to serve as a single complete reference, and the variations in quality were pretty dramatic.

I was a little confused as to what I’d be reading after seeing the cover image of some snow plodding, and flicking through and seeing more images of snow, skiing, cycling and a lot of weight training. Was this a fitness book for alpinists or what?

The book is actually aimed at the broad spectrum of climbers from boulderers right through to snowy mountaineers. Its real purpose is hidden in the first chapter – it is intended as a supplement to the other books on training for climbing, focusing on ‘conditioning’ where the other books focus on ‘coaching’, according to soles. The problem here is that conditioning for climbers should involve mostly climbing related activites, which this book doesn’t deal with in detail (but the others do!). The bulk of it deals with supplementary weight training for climbers, with sections on general fitness, nutrition, flexibility and planning your training program.

I my opinion, and those of many other climbing coaches, weight training is of very limited usefulness for the vast bulk of climbers out there. It’s value for climbers lies when there is no access to any climbing (like if you work on a oil rig), if you have a muscle imbalance that needs specifically targeting to eliminate injury, or where the climbing you have access to has insufficient variety to work the prime movers hard.

Almost all climbers will be in one of the above situations at some point in their careers, and they will find the content of this book useful. But I found the opening section of the resistance training section where soles extorts the value of resistance training for climbers more than a little cringeworthy and misleading. Apart from this, there is useful information about the use of weights and other resistance devices for climbers and the practical issues surrounding it. But far more detail was needed in the sections on two of the most important basic resistance devices for climbers – the fingerboard and campus board.

The central opportunity with this title is to inform climbers exactly when and how much they should use resistance training. Soles attacks this task in the section on planning training programs for different climbing goals. But in my opinion he has advocated far too much resistance training and the detail on the climbing activities is sketchy to say the least. The result of following one of these programs, I think, would be good weight lifter, but not as good a climber as one could be on a more sport specific program.

Thankfully, the book isn’t all about weights. It real value comes in the nutrition section, which is well written, practical and informative and this is where it earns it’s place on a committed climber’s bookshelf. Good advice on shopping and meal strategies, body mass and composition, supplementation and dietary pitfalls. It would be good to see a committed nutrition for climbers title from Soles maybe? I might disagree a little with the minimum body mass figures for performance climbing given, in fact I’ve proven them wrong myself. But no one has any empirical data to go on here yet.

There are a lot of useful facts generally and Soles writing style is easier to read that some other books out there. If you are already convinced you need to be doing some weights for some specific reason, this book will help you make the best progress, but I would be wary of using this book solely to plan your training, or you will be spending way too much time pumping iron and not enough learning to climb. I think this book will help a great deal of climbers get a better handle on good nutrition specific to climbing situations, as well as some other useful training related facts. If you already own four or more of the climbing-training titles out there, get this one too. If not, stick to something that is aimed more at what’s important for climbers.

Footnote: I mentioned above that I found the opening section on the value of resistance training a bit scary – what specifically?

It’s the notion that if you don’t do weight training to supplement your climbing you are putting yourself at risk of injury. This is not at all necessarily true. Sure, unbalanced climbing that has insufficient variety in one aspect such as hold type, angle move type or movement style often sets up the conditions for dangerous muscle imbalance or overuse syndromes. But varied and sensible climbing need not create these conditions at all. In fact, climbing movement is so varied that it can actually protect against imbalances rather than cause them. I would suggest that self-coached weight training is far more likely to result in imbalance problems that just going climbing.

Poor technique and variety in climbing are the problem, not climbing per se. But Soles opening section gives a different message. Soles also tells us not to listen to “the number one myth about weight training is that you will get too big. Since climbing is a sport where strength-to-mass ratio plays a significant role in performance, this fear is understandable, if misguided”. But then no satisfactory argument is provided for it being misguided. I do not think it is misguided, generally speaking.

I feel that following the programs of weights based resistance training advocated by Soles would indeed lead to some excess muscle mass for climbing as well as a missed opportunity to use this training time for more specific training activities that contributed much better overall to climbing performance.

How to be a sponsored climber

Another email I get a lot from climbers is one asking “how can I go about getting some sponsorship?” or asking what grade do you have to climb to get sponsored. This is another subject I think it’s important to write about on this blog, because for lots of young climbers it’s a really bad distraction and will influence them to make choices that will ultimately limit their climbing, not empower it.

So, how do you get sponsored? Well the first thing I should say is I am probably not the best person to ask. I am much better at climbing than getting huge sponsorship deals (I like it that way round), but maybe it’s good to point that out - it’s a skill in itself, completely separate from how hard you climb.

On the whole, how much sponsorship you can get has only a little to do with how hard you climb, and the climbing part can be answered in a couple of sentences:

If you want to be a professional climber, take whatever the current cutting edge is in the niche you want to operate in, and better it, convincingly. And understand that you have to do that first, before the sponsorship comes. I know it would help if it was the other way round, but it’s not going to be, so it’s better to accept that from the start.

Right, thats the easy part out of the way, now the hard part. No matter where you are at with your climbing, the challenge to actually turning that into a relationship with a company is your ability to role play the cash strapped marketing manager. This is where most climbers go wrong. This is what you have to imagine:

You are the marketing manager of the company you want to get the deal with, your marketing budget for the year was pretty damn small to start with, and you’ve spent most of it already and allocated the rest twice over already. A glossy pamphlet with a highly professional looking and reading cover letter comes in, among many other bits of mail in a big pile you have to read. It’s a request to be considered for the sponsored athlete team of the company. You’ve got 20 emails to write before your meeting in half an hour, so this request has about 30 seconds to sound good enough to make the headache of redoing all your budget sums for the rest of the year a good idea. (first hint: why should you be sponsored in a couple of sentences, or better still a couple of unmistakeable images?).

If you think your marketing manager might not already know who you are and lots of things about you, wait until they will have. So you have to be able to remind them instantly in words or images why you are exactly what their marketing tactics need to sell more of whatever it is they sell. Did that one pass you by? It does for many young climbers. That last point was where most go wrong. They think that the sponsorship is reward for climbing hard. It’s not. Its about your sponsor being able to sell more product.

So however you go about getting the sponsorship (and there are many ways), remember it is a task of saying “this is how I can help you connect with your customers”, and not “this is how hard I climb”.

How can you help a company present a stronger image, carry a message to more people, through more and better channels and how can you make these ideas sound better than whatever the company are doing right now. Make sure you know these answers inside out, with numbers, and images to back you up, before you approach. 

Another good approach is not to approach at all. One of the big problems with getting sponsorship is budget cycles. Whenever you approach, it’s sods law the budget has already been spent. Sometimes, it can be better just to keep focusing on building yourself into such a valuable target for companies (hint: once again, climbing is probably the least of this) that it’s inevitable at least one marketing manager will recognise that your 20,000 blog readers per month are a far more valuable asset to get closer to than trying to make traditional ads that anyone will notice.

I’m sure I’ve given a fairly clear perspective on how to approach this, but one final point; the most important one. Whatever you do, don’t rely on the hope you’ll ever pay your bills with sponsorship. You won’t. After several years of trying I got on much better when I realised that looking outside of sponsorship for different types of income compatible with a climbing life was a much better strategy. For me it was writing, lecturing, coaching, labouring, internet retailing and, yes, some sponsorship too.

With trying to be a sponsored athlete you are entering the world of advertising, and successful advertising means being ahead of the curve. If you have to ask others what they are doing right now, you are behind the curve. To be ahead of the curve you’ll need to anticipate what will make marketing managers sit up and rub their eyes next year.

Anyone for a marketing degree? Followed by a multimedia masters? Could be a better idea than a gap year ‘to concentrate on your climbing’. I had two gap years, it didn’t concentrate my climbing as much as I’d have liked, but being broke did concentrate the mind.

Modern trends in city dwelling trad climbers

Following on from my last post where I said people often email and tell me what grades they climb in different disciplines and ask how they can improve. Of course it’s a very complicated picture, but sometimes it’s not so hard to pick out some obvious clues.

One very common clue to identifying weaknesses is the balance of strengths, or grades across the disciplines. Lets take a wee look at these in turn.

How many pull-ups can you do on a first joint edge (small campus board rung) on different grip types? Based on my observations as a coach, for about 7/8 out of ten climbers, they will do much better using a crimp grip than either four or three fingers openhanded. If thats you, you’ve found a weakness to train. Simple! Keep climbing openhanded on almost everything until you strengths on each grip type match. If you don’t, it’s your loss. If you do the hard learning about why it’s important as I stressed in the last important, you wouldn’t need any convincing why you need to go to all this trouble and spend a couple of years breaking your crimping habit.

A second one that stands out a mile with trad climbers who live in cities and spend a lot of time climbing indoors is their grades. A common one these days is “I climb F7a, Font 7a and HVS/E1” or at a higher level “F8a, Font 8a and E4” To me as a coach this now sounds normal because I’ve heard it so many times. But to me as a climber I think “What?!” 

A friend of mine is convinced if you can do Font 7c bouldering , you should be able to do F8c routes so long as you do any sort of decent stamina work. And it’s probably true for a lot of routes. As for trad - the crux of a benchmark E9 like Parthian Shot is Font 7a!

So what is all this saying? Climbers are often WAAAAY too stuck in a “climbing harder equals being stronger” paradigm and have completely forgotten to value tactics and technique. At most busy city climbing walls, if you come in every night for a week, you will come across a guy who can really climb well, but is weak as a kitten. He’ll consistently flash a certain grade on any type of terrain, every time. Yet he/she is much weaker than you. That person is your coach. Befriend them, watch their every move and ask them relentlessly what their background is. Copy it.

How do I get better?! (in one email)

Averaging out at once every day, I get a very similar email, which goes roughly like this (with minor variations):

“Hi Dave, I’m a really keen climber. I’ve been climbing for (x) years and can do (x) on sport/ trad and I’m bouldering about (x). I go to the wall/crag (x) times a week and out climbing at weekends. I really want to keep improving but I seem to have hit a bit of a plateau and don’t feel I’m getting better as fast as I could. Is there anything I should be thinking about doing now to break into the next level? Thanks in advance.”

Sometimes it adds a couple of lines about what the climber habitually does to train and asks “where am I going wrong?”

It’s great to get these emails and know there are so many keen climbers out there feeling the same way as I do. I know that for every person who sends this type of email to someone they feel might have an answer for them, there are many times more people who feel like sending it but don’t for one reason or another. So I thought I should really share publicly the answer I write back, which is broadly the same each time as you’ll see why:

“Hi, Thanks for the email and good to hear you are psyched to get better at climbing. It’s not really possible for me to identify the areas you should focus on with your training without having much more information about your climbing and training habits. And even then the answers would be a lot more than I could fit into one email.

Basically you have two choices to break out of your plateau, Right now you don’t have the information to analyse your own climbing and identify the areas to work on or change. You could either shortcut the process of learning this information by hiring a coach to make a thorough assessment of your climbing and make the decisions for you, or you could learn to do it yourself. 

Learning this information is really the hard part of getting to be a better climber, doing the training is the easy part! It takes many years to learn everything you need to know to design your own program very well. It took me 6 years of full time study and many more years of soaking up every piece of information I could. I’d totally recommend doing this because you can adapt your training practice as you progress or your goals change. 

The worst situation for your improvement is to fall between two stools and take neither path. You’ll inevitably make lots of mistakes, focus on the wrong things and end up losing a lot of time not improving nearly as fast as you could given your available resources. Choose which path you want to take and go for it! Good luck.”

The first message in this is really worth re-iterating - For one climber, a mix of poor footwork, over-reliance on strength training bringing down technique, lack of variety in angle or hold type, or missed opportunity to supplement climbing training at home could be among a longer list of things needing changing. For the next climber, it might be a totally different set of problems. 

Most climbers carry around an incomplete picture of what to value and work on to get better at climbing. So they only follow the things in their picture. A good coach might fill in the rest for you very quickly. This is the shortcut. If it suits your circumstances and goals, take the shortcut! If you want to be a lifelong follower of climbing, take the hard road and learn the rest of the picture yourself, in the long run this will be a shortcut for you.

For those who take the self-coaching path, you are already ‘on it’ by reading this blog. Good one! Keep in mind that actually doing the training is the easy part. Your constant challenge is to be doing the right training at any given moment. So for every hour of training, it would really get you further if you did at least the same in learning about training (reading, watching, thinking, analysing). 

Make sure you are getting information from every channel available - things like: this blog, many other writers on this subject online, reading books on training and not just ones specific to climbing, motivation, watching good climbers, asking good climbers what they do. (Hint: Lots of very specific questions in a row will get much more than one general question like ‘How do I get better?’).

Which path are you on? Don’t fall between two stools.

PS: I am not sure if that final figure of speech is a British thing or not, but for anyone who hasn’t heard it before, please note it refers to stool as in the chair.

New research published on finger endurance

My undergraduate research project investigating determinants of finger endurance in trained climbers was recently published in the Journal of Sport Sciences. You can see the details here or access the full paper if you have access to the scientific journals through an academic or other institution. A huge thanks to Stan Grant for encouraging me to keep going with the log preparation of the manuscript for submission and to everyone that worked with me on the paper and volunteered for the research itself.

We observed that climbers were not dramatically better at tolerating occlusive isometric contractions of the finger flexors (as you get in difficult climbing), but were surprisingly good at sustaining long periods of intermittent high force isometric contractions compared to untrained people. This could be down to an ability to perfuse the muscles very rapidly and recover from the contractions while reaching for the next hold. Not surprisingly, we also observed yet another confirmation that pure finger strength, and especially finger strength to weight ratio was a strong predictor of climbing level.

The intermittent isometric muscle contractions of our fingers in climbing are not that common in strength and endurance dependent sports, and there is still much to be learned about the exact causes of failure to maintain force output and sequence of chemical events that happen deep in the exercising muscle during fatigue. 

Big up to anyone out there willing to take up this mantle and help us to learn more about the physiological limitations in climbing. The continued dramatic rises in the level of ability of the worlds top climbers really shows that we are nowhere yet, either with our understanding, or what could be done with it.
