Technique: Vision control

By Chris Ford

Taking control of your vision can have a huge impact on the speed and flow of your riding. But becoming faster isn't just about getting the techniques right, it’s also about practice.

Understanding how vision works

The first step to riding better through vision control is to know how the different parts of our vision work. Here we have to dip into neuroscience, but stick with us as it’s important stuff. Your eyes pick up information through two types of vision – focal and ambient – and these work quite separately, delivering information from the eyes along different pathways to different places in the brain.

Focal vision is concerned with what we look at and is used to identify objects.

Ambient vision picks up information from everything that is in front of us, within range of the eyes.

While focal vision takes time to decide where to look then process the information, ambient vision is instant and unconscious because we don’t think about what it sees, we just see it and react to it. Think broadband vision – it’s always on, always working.

Ambient vision is most important for movement control and for managing our bodies as we adjust to changes in balance or our environment. Think about walking down the road and sending a text. You rely totally on focal vision to write the text, but at the same time you rely totally on ambient vision to see where you are going and not trip or bump into things.

Mountain biking as an applied science

Understanding the science means we can now apply it to the trails. The way to do this is to use each visual system to best effect, to keep us fast, smooth and safe.

Focal vision allows us to look ahead, scan for specific objects or trail sections that we need to prepare for. We know focal vision is relatively slow, so we have to look ahead to give our eyes time to move and focus, then our brain time to process. The faster you go, the less time you have, so you need to look further ahead.

Ambient vision allows us to see the trail as it approaches us and to control our reaction to that trail. Our ambient vision works quickly and keeps us balanced, so we have to trust it to do its job. We still need good body position and footwork, but with those things in place it’s our ambient vision that gets us through with speed, balance and good control.

Managing focal vision

The biggest problem most riders face is letting their focus gradually get sucked in to the front wheel. Often this happens when you spot a big rock way ahead, then watch it all the way until you hit it. Instead of letting your focal vision hand over to your ambient vision as the terrain approaches, you find yourself looking down, out of control and not ready for what comes next.

To change this you need to look at the trail in bite-sized chunks, or sections. For example, a corner would be a section, or a rock garden, or a jumble of tree roots – any manageable feature, obstacle or defined part of the trail can be called a section. Now follow these simple rules:

  • Before entering a section look right through it, scanning the trail quickly for any major features
  • Once in the section, make sure you look to the exit and down the trail beyond it
  • As you approach the exit, focus on the entry to the next section

The idea is to train your focal vision to keep moving ahead of you, and breaking the trail up into chunks like this gives you clear points for your eyes to aim for. For example, as soon as you enter a tight turn you are rotating your head and shoulders to look for the exit. In the second half of the turn you are choosing your line through to the next trail section.

When cornering, always look through the corner to the exit. where your head and shoulders lead, your body will follow.: when cornering, always look through the corner to the exit. where your head and shoulders lead, your body will follow.

Getting faster with vision control

One of the most exciting things about improving your vision is the effect it can have on your speed. If you have a trail you ride often, and know you have the skills to clean it, try working on your vision to ride it faster and faster.

1. First look at how it breaks into sections.

2. Then, as you ride it, try to move your focus ahead of you, section by section, and allow your ambient vision to control your instant, intuitive reactions to the trail as it reaches you.

3. Next think about the places where you use your brakes, and why. Often, braking is the result of information overload as the trail comes at you too fast - you can’t process it, you start to feel out of control, so you hit the brakes.

But there’s an alternative to slowing down – pull in the information sooner and give yourself more time to process it. In other words, just as you reach for the levers, try looking further down the trail instead. Trust your ambient vision to handle what you’re about to hit and start working your focal vision on the obstacles further ahead.

Head control affects vision control

Head movements affect balance and the more rapid the movement, or if it is combined with the feet being unstable, the greater the impact on balance. This is partly caused by the disruption to the inner ear but also by the effect of rapid movements on your vision. If you can ensure that your head and shoulders flow smoothly down the trail, whatever your arms and legs are doing, you’ll retain good vision.

This is where vision ties in closely to good footwork and body position. You need relaxed arms and legs, elbows low and bent, knees bent, hips flexible and ready to move – every part of your body needs to absorb the shocks from the trail so your torso and head can move calmly and quickly forwards.

When it all works and you feel as though the trail is approaching you at a sensible speed, even though you’re riding faster than ever before, then you know you’ve got vision control mastered.

Cornering

  • Scan the trail: As you straighten up and get into a comfortable position for high-speed riding, start to scan ahead and use your focal vision to check for obstacles and select a line to deal with them effectively.
  • Look ahead: Approaching the exit of the last turn you can look far down the trail, trusting your ambient vision to get you through the rest of the turn as you start to pick up speed.
  • Prepare for the next turn: Once a turn is coming to an end you need to be looking through the trail towards the next section, in this case a second switchback, and figuring out your entry line, speed and body setup.
  • Look through: As you enter a turn section look through the trail to get your line and start to figure out your exit route.
  • Lead with your head: By turning your head and shoulders you can lean the bike more effectively through the turn, as well as making sure you look for your exit point in good time. Weight is centred on the bike, not back, to ensure good front wheel grip.

Climbing

  • Chin up: With your head forward keep your chin up and look ahead, not down at the front wheel. Line choice is important and you also need to plan for surges of energy to get over steps or steep sections.
  • Weight the wheel: Keep your chest low and forwards to ensure the front wheel has enough weight over it to keep it on the trail and tracking straight.
  • Keep it smooth: Smooth application of power through good pedalling technique is vital on steep, loose, long climbs like this. It also lets you sit fairly still, allowing your focal vision to work more effectively as you select your lines.
  • On the nose: Slide forwards on the saddle and sit right on the nose. It’s not always comfortable but it lets you maintain traction and still stretch your body forwards.

Drop-offs

  • Drop your heels: Keep your heels down on steep roll-offs for maximum grip on the pedals and good control of bike and body as you accelerate forward then hit the bottom.
  • Trust yourself: Let your ambient vision do all the close control work as you focus ahead, knowing that you will pick up speed at the bottom of the drop.

On fast downs, it’s crucial to focus as far ahead as possible to give your brain time to react: on fast downs, it’s crucial to focus as far ahead as possible to give your brain time to react

Steep descents

  • Night rider: In low light your ambient vision improves while focal vision slows down, so even in dark, rocky terrain you must look ahead and not down at the trail below or just in front of you.
  • Eyes up: You can see the front of your front tyre even if you don’t look at it, so look ahead and trust your balance and your bike to handle the rocks that are under you already.
  • Set up for smoothness: With body pushed back and chest low you can keep your arms flexible, ensuring that all bumps are absorbed and your head and upper body move smoothly down the trail.
  • Stable platforms: Keep your cranks level and heels down so your feet will stay firmly on the pedals, even on steep and rocky terrain.

Top tips for practicing vision control

Get a focus: When sessioning a trail section get a friend to stand round the corner, or at the bottom of a slope, and look to them as soon as you can. If you’re alone take some tape and tie it to a tree or rock as a focal vision marker.

The right pack: If you use a rucksack make sure it’s bike specific. These are designed to sit lower on your back than regular packs, so when you tip your head back it doesn’t interfere with your helmet and restrict your vision. Also, be sure to tighten waist and chest straps on descents so the pack doesn’t bounce up and hit your helmet.

Set-up tips for good vision control

Top tips: wax: top tips: wax

Wax up: Wet, dirty and misted-up glasses make seeing the trail that much harder, so take steps to protect your vision. To keep lenses cleaner, mist-free and better at shedding raindrops you can wax them up. First get them perfectly clean, then rub a bit of candle wax on both sides, polish it on with kitchen paper or lint-free cloth, then reapply and polish again to make sure you have a good coating. This makes a huge difference, especially on steamy winter rides. Don’t even think about hitting the trails without glasses, or you’ll get all manner of muck in your eyes.

Get the low view: Dropping your saddle for descents lets you sink your body lower on the bike, without getting bucked forwards suddenly if the back wheel hits larger rocks. In training this lets you take a bolder approach to rough terrain as you learn to trust your ambient vision without worrying about larger obstacles. But there’s another effect – by bringing your eyes down and back you get a better view of the trail hitting your wheel than you would if your head was high over the bars.  This improves your unconscious bike handling and reduces the temptation to tilt your head down.

  • Can't agree more with this, same principles apply to skiing. I can remember when I had my first lesson on 'visioning' as a young lad many moons ago when i had started to do a wee bit of racing. yes, having the technical skills is of course vitaly important, but 'visioning' had, and still has, the greatest impact on my skiing and biking.

    Kev

    PS top tip on waxing, never seen taht before!

  • brings a whole new meaning to waxing!

  • Great, I heard this under articles about target fixation, where you look at an object wanting to miss it, and as your concentration is on the object, lo and behold you hit it!

    Good tip on the waxing of glasses

  • Hi Chris

    Nice article, but I think your neuroscience is a bit wonky. Most neuroscientists refer to foveal vision and peripheral vision rather than focal and ambient. Light is focused across the whole retina equally well, it's just that the fovea contains the most dense concentration of light sensitive 'cone' cells.

    The reason we need to train ourselves not to use our foveal vision is not because it is intrinsically slower but because it is so small. Being small we have to move our eyes in a rapid process known as a saccade to fixate the fovea on the 'thing of interest'. The problem with this for any sport is that in terms of reaction time this is really, really slow. Not only does visual processing have to progress to higher areas to initiate a saccade, during the saccade itself visual perception is effectively switched off to prevent 'blur' signal from being processed as movement.

    Because our visual system has this 'blur' aversion, we find ourselves involuntarily tracking visual scenes, next time you're on a train try to allow the ground outside the window to blur past you eyes, it's impossible unless you fixate on something distant. This tracking means constant saccades and thus slower reaction times. Raising our foveal vision as far down the trail as possible keeps our eyes stable and free from saccades allowing the peripheral system to pick up the most information it can. So perceptually it might seem like peripheral blur, but subconsciously we're reacting to the visual stimuli in a fraction of the time it would take if we bothered our higher brain.

    Sorry to nitpick, but you also said 'Ambient vision is instant and unconscious', you mean subconscious; the unconscious part comes after the crash ;)

    Cheers

    Jess - I studied eye tracking in table tennis players many years ago, think I swalloed the textbook - Sorry.

  • Hi Chris

    On your recommendation I have bought the excellent 24 track compilation 'Ambient Vision -Various Artists' and it now takes pride of place in my record collection.

    Sometimes I listen to it on my iPod whilst mountain biking and I have to say the combination of mellow beats and chilled vibes improves my mountain biking no end! I also listen to it whilst driving my Ford Focal with similar results.

    My Favourite track is 'On the peripheral' by MC Flubber.

    Thanks also to jweston for her excellent review of the article.

    Nitpicking? Or picking on a nit?

  • Yikes! Shocking!

    I've decided to take my CD back to HMV and swap it for something by Pat Benetar or William Shatner or both (if such a dream CD exists).

    In case you're wondering, I did I rip it (off) to MP3 first.

  • Hi Jess

    Thanks for the information - I have always tried to pull together as much research as possible for both my own coaching development work and my features, so your feedback is a great help.

    The terms "ambient" and "focal" vision came from a book called Frontiers in Cognitive Neuroscience, published by the MIT Press, which I found useful as part of my research. As I understand it the terms relate back to work carried out by Trevarthen in 1968 and subsequently Mountcastle in 1976. I'm not a neuroscientist so I'm not going to argue with your analysis, but it seems that there are different forms of language in use both within science and within everyday English. The challenge for me as a coach and skills author is to use language which is technically sound but also encorages the right understanding and application of skills.

    This is why I like "ambient vision" and prefer it to "peripheral vision". Most people think of peripheral as being at the side of their view, what they see from the "corner of their eye". What I want riders to do is train their eyes to focus further ahead and allow ambient vision to pick up what is actually right in front of them - not objects on the periphery of the trail but things they're about to ride over. Hence my preference for this form of language.

    Other material in the feature came from work on vision in drivers, taken out of studies carried out in Norway, and another interesting paper I read about the impact of body movements and body stability on vision.

    As with all research there will be questions raised and I'm happy for that to happen - as I said I am not an expert in this field but have researched it to help me understand how vision affects performance on the bike. If you can add to that pool of knowledge then I'm really glad you took the time to write - not being a smart arse here - it's good to see some detailed work being applied to mountain bike riding theory and practice.
