The Benefits of Putting Your Hands in the Center of the Bar

In this video, we're going to talk about the benefits of putting your hands in the center of the bar when you're training.
Putting your hands in the center of the bar allows you to use a wider range of motion, which will help you develop better strength and flexibility. You'll also be able to improve your performance in the gym, and increase your endurance. So make sure to watch this video, and learn how to put your hands in the center of the bar for better results!
When we buy kites we have to decide the size of the bar. Why should we use the smaller bar for the smaller kites and the bigger one for the other ones?
Most beginners put their hands on the end of the bar but pro riders use the center. What is the best place and why? Find it out on this video and learn that the bars are levers type 3.

Thank you so much for the clear explanation, it's the first time I see a rational and scientific explanation to why it's more efficient IN ANY CASE to keep the hands close to the fulcrum

My pleasure

The short and only right answer is: to not make unwanted steering mistakes + easier to move the bar up and down the power line to stay in the sweat spot. Those points are brought up by others. Now about some flaws in your logic and reasoning: 1) Why we have different bar sizes? Because every kite has its maximum turning capability, and in that position steering lines attached to the kite have somewhat fixed (kites twists) distance between them, also the line length to the bar is fixed. So the parameters that determine what the minimal bar width should be to be able to maximum turn a kite are: line length+distance between attachment points of the steering lines at the kite. People will tell you from experience that is is not just the kite size that determines if you can get away with a short bar. Vegas 8m vs a Flysurfer Soul 8m... 40cm bar vs a 60cm bar that will work best. 2) You keep repeating (in your comments to others) that is easier (less muscle force) to turn the bar when hands in the middle close to the center. Just test it yourself, and slide your hands from each side to the depower rope and then ask somebody to hold the bar at the ends. Now try to twist. Next just move your hands away from center 5cm on each side. Now ask your friend which stance was easier for him/her to counter. Spoiler, the stance where your hands were in the middle was the easiest to counter. What comes into play is the fact that the kite-lines-bar is more complex than some mechanical simplified lever system. When you manage to twist your bar some degrees, the kites starts to help you turn, so when you have you have your hands near the middle AND are still capable of passing the point of where the kite will start to help you turn, you are fine. So the reason why it feels quiet easy to turn the kite when you have both hands 4/5 cm from the center is because you can still reach that point where the kites really starts turning without too much effort. TLDR; The way I test what the 'best' bar size is for a given kite: stand in water, and downloop the kite by fishpoling your bar. If you feel that you could get a tighter loop (test by pulling a floater), you need a wider bar, if you feel that you are pivotting the kite instead of turning, your bar is too wide.

1) Great point explanation 2) I don't say it's less force i say it's the same due to observing the formula and that it's a lever type 3. The experience you mention is flawed in the fact that we can put more muscle on on the tip than in the center. I need to get some dynamometer to confirm with weights. Also like your explanation for testing the size of the bar. AS said before the main thing is that you have better precision control in the center and that is where you should keep your arms. Having them more to the tips is not helpful at all. Thanks for your input.

Nice explanation! Thank you?

[@KookProofActivityCenter]

Glad it was helpful!

[@dylankoomen1063]

Nice video dude! Been riding along time already with my hands in the middle because it's relax 😎 but now I also know the science behind it 😜

[@KookProofActivityCenter]

Good to hear! Thanks for the feedback

[@JoshatHomeOffice]

Just came across this video and thought I'd add some additional input to the assumptions and mistakes being made. The first, and biggest mistake is the fulcrum point. It is not at the centre of the bar (with the exception of being way overpowered so the bar locks into the stopper). The fulcrum will be the hand that is at the end of the bar of the rising kite tip. The fact that the rotation point is at the centre of the bar is probably where the confusion comes from. Look up fulcrum to fill that knowledge gap. Now, the perfect analogy of why it takes less force with the hands apart is a garden spade, which is also a type 3 lever. Like a kite bar, the fulcrum point is one of your arms. If you're hands are close together, you will struggle to lift the load. If they are far apart, small movements make fast distance changes. There is a sweet spot in the middle, which is dependent on the intention of the user. The force required to steer a kite is relatively minimal for a person that has muscles tuned to kiting. That's a likely contributor to why your hands are able to get closer together as you progress. A beginner is in a tricky grey area where their muscles haven't been trained yet to apply the forces fully with hands close together, which leaves them in a situation of likely oversteering. Only repetition and practice will overcome this. Although there is some merit to the fact that the kite pulls from both ends of the bar, that will be a relatively small input to the system. This is also why you want to use different sized bars, as the input is exaggerated for the same hand position as the kite size decreases

[@KookProofActivityCenter]

That is a fascinating point you raise. I'm thinking of remaking the video and centering it more on the need to focus on having the hands in the center to have more control over the steering

[@fernandofefo4465]

Valeu, bacana demais o video. Sempre rola esse tema(tamanho da barra) nos grupos de discussão. Junta esse tema com o tamanho das "front lines"(o V mais alto ou mais próximo) em um outro vídeo. Parabéns!!!

[@KookProofActivityCenter]

Obrigado fernando. Tem esse também em Portugues no nosso outro canal. kzbin.info/door/esQiZTM5xg5KOnR0NEV9dQ

[@joakimho4048]

Thx... can u explain How the adjustment mechanism works on the ends of the bar....

[@KookProofActivityCenter]

The adjustment on the bar ends makes the bar bigger or smaller. It was a way that brands found not to have four different bar sizes. Like this, each bar can be changed to have two dimensions. On the example I have, you see the line is connected to one point. If you rotate the piece, it goes smaller or bigger, depending if the line is closer or further away from the tip.

[@GaetanoCrisci]

🔝🔝🔝 thank you for the inside overview!

[@KookProofActivityCenter]

Our pleasure!

[@flamewave0]

Sir you are mixing terms here, having hands close to the middle requires much more force from your hands to move bar, hence if you don't what kite to move about to keep your hands there. If you want to turn kite fast i.e. for kiteloop you should put your hands wide so you can turn kite quick with less force than you would require by having hands in the middle.

[@KookProofActivityCenter]

Not at all, you also don’t need to put your hands on the tip to make the kite turn faster. You do it from the center. That is because it's a lever type 3. Check footage of pro riders making kite loops, and you will see they keep their hands on the center and not on the tip.

[@KookProofActivityCenter]

It also doesn't require more force than on the tip. Check Wikipedia for the lever type 3 and you will understand.

[@zlatko.]

@@KookProofActivityCenter Actually you have to check carefully Wikipedia for lever type 3 forces :) With lever type 3 the closer your hand to the fulcrum(center bar) the more force you have to apply to move the load(kite pull at steering line). The advantages of hands closer to center bar are: 1) stable kite - light movements do not trigger kite response as you need to apply significant force 2) for small(short) movements of hands result into bigger(longer) travel of bar end - what you lose in force you gain in distance

[@KookProofActivityCenter]

There is no more force. It’s actually the same. Think of a fishing pole as it's the same type of lever. You put your hands close and not spread apart. From the internet: In a third class lever, the effort is between the load and the fulcrum. Some examples of third class levers include fishing rods, cricket bats and chopsticks. Third class levers are different from first and second class levers because instead of force multipliers, they are speed multipliers. This means they do not provide a mechanical advantage. In fact, more force is required in a third class lever to move an object. Third class levers are used in applications where speed is important. Because a larger force is applied by the effort, the load travels a further distance. Since the load travels a further distance, its speed is also multiplied www.skwirk.com.au/skwirk/uploadFiles/content/database/files/chapter.2848.body.html
