Nutrition and Diet.




It is time to get back to the plan; we have covered a bit about technique [1], Physiology[2] and Biomechanics[3] This leaves nutrition and fitness, although I doubt I will cover fitness as a “how to” guide as like most technique it changes with the wind.

So how to begin with nutrition? It has certainly got to be one of the scariest parts of all types of sport training as it has the ability to have a big impact on our daily lives. 

Our bodies are effectively a complex machine, which require a wide range of nutrients, food, vitamins and energy to keep going. A balanced diet is the optimum level of these nutrients for an average person.


 NHS

Ok so no one is “average”, but we can agree that by having too much fat and unhealthy food can cause people to become overweight and one way to rectify this is to adjust our diet.  The different diet types are seemingly endless from organisations like Weightwatchers and Slimmingworld to specific diets like Atkins and the Special K challenge. 



All of these have one goal, to loose weight and the impact on the body is tremendous.  We see it all the time in the Glamour Magazine.   They all describe and show how people have changed physically, and sometimes mentally, for the better/worse.

This is where it gets interesting; this methodology can be applied to an athlete.  Imagine if you can improve your performance through your diet.  How much of an advantage can that give you? In some cases it can make the difference as it did for Hannah Miley in the European championships[4].

Like the weight loss diets, the variations on performance diets are endless. A couple of classic examples of how a diet is used to affect ones performance is within Cycling and Body building.

In cycling, Carb loading is used quite a lot so what are Carbs or Carbohydrates? Well they are compound groups, which give us energy.  These compounds are the first place our body goes to get energy.  Now Carb loading is effectively a process of giving the body an excess of carbohydrates to use.

You do it by almost staving yourself of Carbohydrate rich food, for example potatoes, pasta etc, for a couple of days (or more) before the competition.  Then on the day of the competition you eat a plate of highly rich Carbohydrate food.  The theory is that this gives you a huge energy boast.

It is a very clever way of using food to boost your performance but it is not without its risks.  Those few days before can cause the body to be lethargic and irritable aka not great for your partner or work colleagues.

It is time for another example; welcome to the world of the Body Builder.


It is just physically impossible to get this pumped on pushing weights alone.  A very specific and specialist diet is required, one which is super rich in protein. The protein builds muscle mass if taken at the correct stages of ones fitness regime, maximising muscle growth.

In archery neither of these options is really preferable although I have known some archers to use parts of both examples above for their specific training regimes. 

The general advice which is given to archers is little and often, effectively become a farmyard animal.  The constant ingesting of food will maintain energy levels at a constant and consistent level and therefore, in theory, maintain performance.

To help athletes/bodybuilders achieve more from their workout some take supplements.  A supplement is an artificial/synthetic way of increasing a specific mineral or compound within the body. The humble vitamin C or Cod liver oil tablet is an example of such a supplement.


Taking supplements at specific times during training can maximum growth in muscles and burn the most amount of fat.

The list of what supplements you can buy is long, with variation on taste, type and effect.  No doubt they do have their place for ones training regime, but where does the line sit between illegal and legal ways of boasting ones performance?

Using food supplements and specialist diets like carb loading is a legal way of boasting ones performance yet a steroid, which is a banned drug, isn’t allowed.

The role of drugs in sports have been well documented. With recent cases of Lance Armstrong[5] and the report from Australia saying drugs in sport was widespread[6] .

But what drives someone to take this risk of using banned substances?  Well it is one thing, psychology, the need and desire to win at all costs.

The anguish of Archery/Sport


Well it is now gone 9pm and I am back in the house with my girlfriend.  She has had a busy day doing the chores and garden. She has done everything, even ironed my shirt ready for work tomorrow. Without that support I wouldn’t be here on the computer.

For my day, well I can’t really say the same.  I shot below my average and the team came second.  Overall, I am pretty disappointed with my performance. It’s easy to beat yourself up over it and think it was you who let down the team.

For the top athletes it can sometimes feel like you have let the country down. I mean Rebecca Adlington was incredibly emotional after coming 3rd in the Olympics [1].

This is the flip side of sport.  All that effort and practice can amount to nothing.  It is so easy to say it is worth it with a medal around your neck.  But spare a thought for the people who put all the effort in and don’t make it or have careers cruelly cut short though illness and injury. 
These people rarely reach the headlines and if it does it is often tragic. Take Fabrice Muamba who collapsed during a football match on the 27th of March [2].

He has never played again and has had to change his lifestyle completely.

Yet for the rest of us we cannot dwell on these tragedies.  It is back to the training field to perfect my technique and in a fortnight’s time I will try again at another competition.  This time it will be worth it.

Hmm I wonder if my girlfriend will make me another cup of tea for the journey?

Good night.

For the love of Archery/Sport



A break from my normal posting time: it is roughly 5:30am and I am getting up to go for a shoot 60 miles away in another county.  My teammates are due any minute to give me a lift and my girlfriend has kindly made me a cup of tea for the journey.  (She has promptly gone back to bed and is sleeping peacefully)

It does make you think about why we put ourselves through this. The early mornings and long hours practicing, all for a tin medal round your neck- which you are never guaranteed to get.

It can be a tough question to answer but in reality we do because we love it.

We do it for the challenge, the team, the feeling of elation, and the knowledge you are pitting yourself against other competitors on a level playing field.  Athletes like Anya Shrubsole thrive on that challenge [1]


That is the essence of why you do sport. If you win or beat your target, the feeling that you were the best on that day is unassailable.  Nothing and no one can take that away from you.  That is why you keep coming back and putting those long hours in.

Sport has been compared to a drug as you keep going until you have had your fix and then repeat it to try and get the same fix.  I, for example, stopped shooting/coaching for 2 years but yet I came back and never felt better.  With all addictions though it can be disastrous and athletes find it hard to go cold turkey.[2]

I think I best go into that another day as my lift is here.  We are off to a school hall in the middle of a non-descript housing estate.  Glamorous it is not but this is where it begins

Subtle Variations in Technique



We have looked at the forces and a bit about technique so let us take a look at a couple of top archers. The video below show Celine Schobinger and Natalia Valeeva in the recent world championship in Nimes.

Be aware it is 15 min long, but you only really need to view it for a couple of minutes, oh and the commentary is in French aka nonexistent.


Their technique is pretty much identical even though they are from different countries. Their style could be argued as text book.  However there are very subtle variations, for example Celine is left handed and pulls the string to the side of his face compared to Natalia etc.  Now these archers are at their top of their game and neither one has a “better” technique.  The differences are very subtle but very important as it shows that no one archer/athlete is the same. 

So each archer has their own variation on the same technique.  Now others can be considered to have an unorthodox style. Michele Frangilli is the classic example in archery.



The way this guy shots is frankly incredible! He has literally taken the rule book eaten it, regurgitated and then read it.  How he got to this point I have no idea and, try as I might, I cannot find information about it; to even hope to give a reason. 

Although saying that this is not the first time an unorthodox style has proven itself; take Kevin Peterson reverse sweep for an example.  When he first performed this strike/style it was considered unorthodox and went against the usual thinking.

 
It some situations is has proven very effective, but yet still it is only he who does it in the world of cricket.

So would changing Michele Frangilli technique to text book approach improve his performance? Well why not? It has been biometrically proven [1]  that the best stance/style is that demonstrated in the first video. Surely it is therefore better?

Yet there is another train of thought: “if it aint broke don’t fix it”.  He is still a very successful archer and walked away with team gold at the London Olympics [2]

To change or not to change is a key question and requires serious trust dedication on the part of the athlete and coach to even think about attempting it.  As any change can adversely affect an athlete’s performance in the short term.  It can even affect their mental game.

Just think you have reached the UK squad, by performing your way, then asked to changed your style entirely just because it is deemed better. If this change works then, great. If it doesn't it can leave you feeling rejected.

It is very personal thing and it is no wonder when it a certain style doesn't work some of the replies can be very derogatory, particularly if people train elsewhere to try and reach their goal. “Just because I didn’t train with squad they didn’t even check on me” [3]

That is one for the courts to decide but change can reap success, it did for Hannah Miley when she gained weight and changed her sleep patterns to improve her performance.[4]

Not something any usual 23 would do. That is dedication and shows a serious love of her sport.

Physical Forces and Alignment.



Before we get into technique an understanding is required of what physical stress an Archer’s body is under.  The video below is a good overview of this (apologies for the exaggerated American commentary) 

Before we continue, yes it is not 74ft Brady is shooting and no I do not know how many donuts were harmed in the making of this film.
 
With the commentary aside it does give an indication of the physical forces and how archers use the human body, the skeleton structure in particular, to handle it.
 
As mentioned at point (0.38min) in the video by aligning bones in the front arm (the arm holding the bow) this allows the compression force from pulling the bow to be loaded on the bones with only minimal effort from the muscles. This is great for efficiency and means Brady can keep doing the same shot each time.
 
Now let us focus on the right arm or the pulling arm. In the video it comes back and the hand rest under Brady’s chin. The point where the hand and subsequently the string touch his face is known as the reference point. The bow is not drawn much further from this point so Brady is now at full draw.

Take a look picture (a) a photo from behind of Taylor Worth (I couldn’t find a picture of Brady from this angle) at full draw. Notice how the string lings up with elbow. Then look at picture (b) a face front picture of Brady. Now notice how the arrow is lined up directly with the elbow. 

                                                Picture (a)                                                                    
Picture (b)
What you are looking at in archery terms is the draw force line or put simply alignment.  This is a text book position at full draw. It is solid, the force is being held directly inline, perfect really.  We can surmise that the force of the bow is being held by the right arm/pulling arm, in reality this is not the case. Nearly all the work/force is being held on the back muscles.

From this video see how the back muscles are moving and working during the shot. The back muscles are what we want to use during shooting. They are strong and can take 56lb of force as related in the video.  (you might need to loop the video is 8 sec long)


What Brady does and other archers of his caliber do can be classed as text book technique. It is worth knowing that the application of this technique can differ. 

Bloggers Note
This post has just taken a brief (text book) review to handling the power of a bow and in the process touched on technique. Now there is much more about technique than what I have written. There are volumes dedicated to this subject matter. This a blog not a book so don't shoot me on the bits i have missed.
