This article is to show a possible approach to the second jump in the Kata Kanku-Sho. Here the jump variant Yoko-Tobi-Geri (landing Ushiro-Geri) is explained and defined as training goal.
This is only meant to be a supplement to the previous contributions on the subject of jump training (see also Jump Training 3 - Coordination and Technique). Maybe new training ideas will arise for one or the other.

The theory of the jump - Yoko-Tobi-Geri / Ushiro-Tobi-Geri
Theoretical consideration: Even if you only stay in the air for 0.5 seconds when jumping, and measurements from sports universities have shown that, for example, a Karateka can accelerate Yoko-Geri's kick with up to 10-14 meters per second, an interesting fact results!
Because the kick or heel of the Yoko-Geri only covers just under a metre (depending on leg length), you only need 0.1 to 0.07 seconds for the kick. A little more time may be necessary to pull the leg back correctly into the starting position. So you don't even need half of the time you would have for the kick in the air!
And since the mass of the lower leg is only 5% of the total body mass (martial arts and mathematics), you need relatively little energy for the kick.
The adjusting screws are therefore: jumping power (maximum and fast power) and coordination/technique (optimise the sequence of movements, no unnecessary movements, make small/knees to the chest)...
Practice - 6 steps to success
I have taken the liberty of breaking the jump down into 6 steps or individual parts in order to have a structured schedule of how to realize this very special jump. A short video with all training steps in short form I have cut together. It is available below and on YouTube. Have fun while practicing! 🙂
Step 1 - Jump up straight
At first, simply jump up straight and bring your knees towards your chest. This is especially useful for gaining height and training the jump. This is where the training from the previous articles on jumping, strength and coordination training helps.
Step 2 - Turn in the air
In the next step we jump straight up again, and then try to turn 180 degrees in the air.
Step 3 - Training Yoko-Tobi-Geri
This can be learned relatively quickly by kicking against, for example, a sandbag leaning against a wall. A soft floor mat in the gym will do the same! 🙂 If you still have some inhibitions when jumping up, you can practice the Yoko-Geri by doing it while standing.
Later on you can simply jump against the mat/sandbag and when you put your foot on the obstacle, you can immediately push off again. This way you get a feeling for the technique in no time. Once you have a feeling for the focus of the technique Yoko-Toki-Geri, you move on to the next step.
Step 4 - Improve Yoko-Tobi-Geri
Now you try to kick in the air - without any resistance or physical target. You have to think about the target point. I personally try to aim at my own chin height about 1.5 meters away from me when jumping.
It is important to focus on the clean high jump and the precisely timed emergence of the Yoko-Geri, rather than on landing.
The speed is also very important. Here you should try to find a balance between clean technique and speed of execution. A narrow degree, which is individual for everyone. The only thing that helps here is to try it out until you feel comfortable in the jump. 🙂
Step 5 - Assemble and try!
In step 5, we should already be able to jump straight-up, body-in-the-air and fast-and-control a Yoko Tobi Geri kick. The landing itself and the Ushiro-Geri during landing has already been explained in the previous articles (Jump Training Part 1-3).
Now you can start to put all the fragments together and coordinate the whole process. Here you should already try to take the position as in the kata, and then it is practice, practice, practice... Again and again only this one complete sequence from the backswing before the jump to the standing up after the jump in Shuto-Uke Kokutsu-Dachi.
Step 6 - Repeat until the thighs burn
The whole thing from step 5 should then be repeated until the thighs burn. After the 4-5 jump at the latest, most of the jumpers will probably be a little less clean in terms of execution. This makes it all the more important to have a close look at the landing again and to optimize it, also to prevent injuries and long-term damage due to incorrect landing.
Hint: Jump training is always best in a separate training unit!
Even if the jump works out quite well, you should incorporate the coordination and also the strength exercises from the jump training into your training plan every now and then. Because the jump training does not only train jumping, because it also provides a firm and stable stand, especially in karate!
Conclusion on the Yoko-Tobi-Geri from Kanku-Sho
I know that my jump is not 100% either. You can always do better! This is what makes training so much fun for me personally - there is always something to do and to improve. And it won't be boring for the next decades. In this sense: Have fun with training. And always think about the regeneration of the body!
Update: Mikazuki-Geri Vs. Yoko-Tobi-Geri
As already mentioned in the previous post it is enough to master the original variation (Mikazuki-Geri) of the second jump in Kata Kankusho, but for the competition area I personally find the variation with Yoko-Tobi-Geri more beautiful.
Like so often everything is a matter of taste!

Nutrition and protein - Protein-rich foods
Besides carbohydrates and fats, protein is one of the main nutrients. Especially competitive athletes, but also hobby athletes have an increased protein requirement, in contrast to non-athletes. The protein requirement for athletes is about 1.1 to 1.5g per kilogram body weight, for bodybuilders even up to 1.8g per kg body weight.

Iain Abernethy - Karate Bunkai Course
Last weekend (February 14th - 15th) the Bunkai course with Iain Abernethy (6th Dan) took place in Achim (near Bremen / Germany). The course was organized and hosted by the Shotokan department of TSV Achim. An estimated 100 to 120 Karateka found their way to Achim to get new ideas and techniques from Iain in … Continue reading "Iain Abernethy - Karate Bunkai Course"
Fitness: Balance Board - ideas and exercises for more body tension
Some time ago I heard that you can train your body tension with a so called balance board. Especially as a Karateka body tension and balance training is very important, so I ordered a balance board. Fortunately, such are available from 20,- EUR (about 25 USD). After a short trial and error I was enthusiastic, … Continue reading "Fitness: Balance Board - ideas and exercises for more body tension"
