Jump Manual Review
Recently Jacob Hiller has created a very useful book Jump Manual for athletes. Being not just theory, this manual is an effective workout which has been tested by time in fact. This manual is extremely special and outstanding.
Teng initial speed jump
Teng decided to jump at first speed is high or far the most important factor in the degree. It consists of run-off in the level of speed and vertical velocity generated by the combination of the human body by the level of capability and technology decisions. Jumping For maximum initial velocity, according to high or far achieved different degrees of horizontal velocity and vertical velocity have different requirements.
High jump, as high as possible in order to achieve a high degree, mainly vertical velocity, therefore, give full play to the level of the speed advantage of the situation of peaceful coexistence, the possible maximum vertical speed, and long jump as far away in order to obtain the degree, as much as possible maximum horizontal velocity.
Flight angle jump
Flight angle is off the end, from beneath, the body center of gravity of the angle between the horizontal direction vault. According to the formula to achieve the highest projectile vacated the highest altitude, flight angle should be at right angles, but not so in practice. Jump will also be required a certain level of speed, to ensure that the body over the bar. Meanwhile, with the development of high jump technique, run faster and faster. The study shows that the momentum gained rapid run-up, you can take-off force to increase the role of take-off leg support to improve the take-off power. Therefore, in the high jump, the increasing emphasis on speed of play and use of run-up to increase the level of take-off effect. If the projection formula based on the requirements, simply go to the pursuit of close to 60 degrees angle Teng, greatly limits the run-up to the level of the speed of play and use. In practice may not increase the vertical velocity and improve the take-off effect. From the back style comparison with the straddle can be seen in the run-up back style of play and the use of horizontal velocity are significantly more than straddle, so the angle of back style of Jumping also significantly less than the straddle, the off effects are superior to straddle. In the long jump, according to the projection formula, the flight angle should be 45 degrees. However, the jump forward when the people ran into the speed can reach 10 m / s or more, but the vertical velocity can not reach that level. If the 45-degree angle to the pursuit of the best mechanics in the formula and reduce the value of horizontal velocity, the jump will be greatly affected much degree. Therefore, in practice, can only be increased as much as possible the level of speed, and reach the largest possible vertical speed. Long Jump when the flight angle is 18 – 24 degrees.
