In karate training we seek to draw maximum effectiveness and power from each technique. This is achieved by using the human body to its fullest. Through extensive study and many thousands of hours of practice and training it is possible to achieve levels of speed and power that may seem beyond the reach of “normal people.” Although we do train or bodies to be stronger and faster, the primary reason for a karate person’s ability to hit harder and faster is a function of muscle control. This is a function of contracting one and relaxing another muscle to achieve maximum speed while at the same time bringing the entire body’s weight to bear.
In each movement whether we are walking, jumping or punching there are multiple muscle groups involved. All movement requires the relaxing of one muscle or muscle group, while the other side contracts. Abductor muscles pull a body part away from the center line of the body. Adductor muscles pull toward the bodies mid line. The power that can be generated with one or the other will be greater if the opposite muscle can be fully relaxed and not pull against the movement. Additionally through the combined use of both muscle groups working in concert it is possible to generate much more power and speed than by using only one muscle group at a time.
One of the first things we learn in karate training speaks to this point, the idea of hikitte. In executing a technique with the upper body, punch, strike or block, the opposite hand is drawn back to a ready position at the hip. This movement is done vigorously and finishes at the same time as the primary technique. The goal is for both sides of the body to be contributing to the power of the technique.
There are many ways to generate power utilized by Karate-ka; changing vertical distance, rotation, vibration, contraction and expansion. Each of these is augmented by bringing the opposite side of the body into the movement.
There are people who, because of their size and strength, can strike with great effect. After learning to harness the power of the entire body focused into the same strike the effect is radically more devastating. A recent example of this was shown in a program aired on the Discovery channel called “The Human Weapon.” This is fairly anecdotal, but they tried to be as scientific as possible. Several martial arts styles were represented and each was given a variety of tasks is order to demonstrate whose style was best. Representatives from Tae Kwon Do, Karate, Boxing, Ninjutsu and others all participated. One of the few truly conclusive tests done allowed each practitioner to pick their most devastating technique in order to demonstrate the “killing blow”. A dummy was used and rigged with sensors and diagnostic equipment. From the data collected the scientists tried to show what the effect of each person’s strike would have been on the human body.
To make a long story short, the most devastating technique used was a hammer fist strike delivered to the solar plexus by the Ninjustsu practitioner. There were some striking things about this. One, he was the smallest of the group in terms of stature and weight. Two, there was no elaborate set up or grab necessary. And three, the strike was delivered from a standing position. How is it possible that this was the most devastating blow delivered from a group of self proclaimed masters? There was total body commitment and focus. No extra energy was wasted. The entire left side of his body was engaged as the right side delivered the blow.
In every technique there will be a dominant and non-dominant side. There will be muscles contracting and relaxing to complete the movement. The goal in every movement is for these opposing groups to work together to allow maximum function.
Punching: In delivering a straight punch or oi-tzuki there are several main points to keep in mind. For simplicity sake I will describe the right side oi-tzuki. As the right leg is propelled forward by the straightening of the left, the body should remain erect. As the lunch leaves the hip it should stay close to the body and only snap into fully rotated, final position as the front foot makes contact with the floor. The left side of the body must remain forward as the left hand is pulled into hikitte position. When the movement is finished, the right fist will be centered in front of the chest with the shoulders and hips square to the target.
There are many muscle groups involved in this motion. The abdominal muscles first and most importantly must keep the body upright and fully connected with the hips. The legs propel the body forward: the rear thigh and calf contract, the toes gripping the floor as the ham-string relaxes. The right arm is propelled up and forward by contracting the shoulder, tricep and pectoral muscle together. This requires relaxing the muscle of the bicep and latisimus. At the same time the opposite muscles are working on the left side to pull the left are back to the hip. The most important part of throwing the oi-tzuki and generating power is that the opposite (left) hip must remain even with the right so that the entire body weight can be propelled toward as a unit. All of the body weight is behind the blow and at the moment of impact the joints of the wrist, elbow, shoulder, hips, knee and ankle are all connected for a split second as the energy is transferred through the first two knuckles of the fist into the target. Force = Mass * Acceleration. The mass is provided by the body, the acceleration by the legs. In order for the full weight of the body to be utilized, the left side must be even with the right.
Striking with other weapons may be somewhat different but the same principals apply. Oi-tzuki is a specialized technique in Shotokan karate and we practice it continuously. There are many other weapons available to us. As an example of a different method of achieving a similar result let us look at chudan ude-uke. With the idea in mind that all blocks are also strikes and all strikes are also blocks, the fore-arm block is an excellent example of F=M*A through a round as opposed to linear movement.
The leg movements will be similar for block or punching but it is the upper body which follows a very different path. Again I will use the right side as an example. The beginning position of the arm for ude-uke has the elbow level with the shoulder, the elbow bent and fist close to the ear. The body begins square to the front/target area. As the left arm pulls back in the usual hikitte movement, the right arm is pulled around and down by the pectoral and latisimus muscles. This in turn requires that the back muscles relax to allow the arm to move quickly around into position in front of the body with the fist level with the shoulder and the elbow pointed toward the floor. The true power is generated not by the movement of the arm but by the rotation of the body. The left hip rotates sharply back while the right hip moves forward leaving the body turned 90 degrees from the target. The rotation of the entire trunk along with the movement of the arm puts the entire body’s weight behind the block. The center line of the body is the center of the rotation as well. As both sides of the body spin the total energy is transferred to the target through the contact point of the arm.
Based on these principals of contraction and relaxation coupled with rotation, the power of the human body is magnified dramatically. It is through use of the entire body as a complete system that this is possible. All blocks, strikes, kicks and punches are thrown not with the limb delivering the blow alone. The opposite side of the body has as much to do with a powerful technique.

TIPS CARA MENGISI BENSIN/BAHAN BAKAR KENDARAAN ANDA
Seorang teman mengirimkan catatan seperti tertulis di bawah ini:
Saya tidak tahu berapa sebenarnya anda membayar saat mengisi bensin....tetapi di sini, di Durban, harga bahan bakar juga mahal. Saya telah bekerja di bidang bahan bakar/bensin selama 31 tahun, sehingga saya bisa memberikan beberapa cara agar uang anda menjadi lebih berharga untuk setiap liter bahan bakar yang anda beli.
Di Marian Hill Pipeline tempat saya bekerja di Durban, dalam waktu 24 jam kami memompakan/menyalur kan kurang lebih 4 juta liter. Satu hari solar, hari berikutnya bahan bakar pesawat jet dan bensin, LRP dan Unleaded. Kami di sini mempunyai tanki penyimpanan sebanyak 34 dengan kapasitas seluruhnya 16.800.000 liter.
BELILAH BAHAN BAKAR ATAU ISILAH MOBIL ATAU MOTOR ANDA DENGAN BAHAN BAKAR PADA WAKTU HARI MASIH PAGI KETIKA TEMPERATUR TANAH MASIH DINGIN
Ingat bahwa semua SPBU mempunyai tanki penyimpanan di bawah tanah. Semakin dingin tanahnya maka semakin padat/kental bahan bakarnya. Jika temperatur mulai panas/hangat, maka bahan bakarnya akan mengembang. Jadi jika membeli bahan bakar pada siang hari atau petang hari.....sebenarnya bahan bakar yang diisikan ke dalam tanki kendaraan anda jelas lebih sedikit dibanding jumlah liter yang anda beli.
Dalam business perminyakan, gravity yang spesifik dan temperatur bensin, diesel dan bahan bakar pesawat jet, ethanol dan produk minyak lainnya punya peranan penting. Kenaikan 1 derajat merupakan hal yang sangat berpengaruh dalam business ini. Tetapi SPBU tidak memberikan ganti rugi/kompensasi karena temperatur.
SALAH SATU YANG PALING PENTING ADALAH ISI BAHAN BAKAR SAAT TANKI KENDARAAN ANDA MASIH SETENGAH PENUH
Alasannya adalah semakin banyak bahan bakar yang ada di tanki kendaraan, maka semakin sedikit udara yang ada di bagian tanki yang kosong. Bensin menguap lebih cepat dari pada yang bisa kita bayangkan. Tanki penyimpanan bensin mempunyai apa yang kita sebut atap yang mengapung yang berfungsi sebagai clearance zero antara bensin dan atmosfer sehingga penguapannya bisa dikurangi. Tidak seperti SPBU, tempat saya bekerja di sini setiap truck yang kami muati ada ganti rugi/kompensasi karena temperatur, sehingga setiap liter yang dibeli jumlahnya benar-benar sesuai/tepat.
YANG PERLU DIINGAT LAGI, JANGAN ISI BENSIN JIKA ADA TRUK BAHAN BAKAR SEDANG MENGISI TANKI PENYIMPANAN
Hampir pasti bensin/solar akan teraduk saat bahan bakar dipompakan dari truck ke tanki penyimpanan, dan kemungkinannya akan ada kotoran di dasar tanki penyimpanan yang teraduk naik dan terikut masuk ke tanki kendaraan anda.
Saya berharap hal ini akan menolong anda untuk mendapatkan nilai yang maksimal dari rupiah yang anda gunakan untuk membeli bensin.
BAGIKAN TIPS INI KEPADA YANG LAIN! MARI KITA SALING BERBAGI INFORMASI UNTUK KEPENTINGAN BERSAMA, UNTUK KEBAIKAN MANUSIA
