I High School sports specialty health, the net height of 1.85, best of 10 seconds 100 meters 8,200 meters 22 seconds 6, are Notes from, and triple jump could be on the 14 meters, 110 meters to ask for training field do? Training time is also enough? There are hurdles is not very difficult to practice? What should be noted that an important aspect, thank you for the,

hurdler require tall, weight control, lower limb length and height than the big, thigh length and leg length ratio and small.

1. Height: The first 18 to 20 Olympic Games men's 110-meter hurdles, the average height of the top 8 players were 1.858 meters, 1.884 meters and 1.864 meters; Article 20 and 21 Olympic Games women's 100-meter hurdles before the average height of 6 were 1.666 and 1.70 meters . Height and is conducive to cross the hurdle fixed height and the use of three-step running across a fixed distance between fields, running 400-meter hurdles, you can reduce the number of columns between the running. But the straight bar athlete's body is also not too high (more than 2 meters men's, women 1.80 m or above), high column is bound to run between the three-step binding, lower than the column dexterity and coordination, and affect the whole running rhythm.

2. Quetelet index (weight / height × 1000): 18

20 Olympic men's 110 meters hurdles athlete Quetelet index were 424,391 and 400, women's best hurdler 350; international quality men's 400 meters hurdles athlete 407. Note tall, shapely athletes are conducive to obtaining a more appropriate step length and stride frequency quickly, while avoiding the burden of excessive body weight can speed up the bar between the speed of running and cross-bar.

3. Longer than the lower limb (lower limb length A / height × 100): This index reflects the lower limb length and center of gravity of the important indicators. Modern hurdle technology from a "hurdle" to run field development, and requirements "hurdle step" closer to the flat to run, to minimize fluctuations in the body center of gravity, so that run-off between the bar and the bar closely link up. Lower extremities, compared with athletes to form a longer high center of gravity, fast-paced "running bar" technology has created favorable conditions.

3. Than the size of the legs [(lower limb length B-calf length A) / calf length A × 100]: This index reflects the human large ratio between leg length. In some cases, lower limb length, thigh length of the short radius of the athletes put smaller teams are conducive to leg lift and accelerate the formation of a good swing speed and a big leg folded over the hurdle technology.

(1) flat race and the hurdles of the time difference: 14 to 17-year-old athlete's requirements are: men's 110-meter hurdles for the 2.5

2.2,400 m column was 4.0 to 3.6; the women's 100 meter hurdles for the 1.6

1.2,400 2.8

2.4 meters. The model of the standard of elite athletes are: Men's 110-meter 1.8 to 2.0,400 m column of 2.5

2.0; the women's 100 meters hurdles 1.0,400 for the 1.2


1.5 m column. The smaller the difference this time, indicating possible hurdle technology.

(2) before and after the halfway hurdles time difference: straight bar should be the second half faster than the previous half, corner bar, the latter half slower than the previous half. "Outline" for 14 to 17-year-old athlete's requirements are: men's 110 meter hurdles from 0.4 to 0.6,400 m column of 3.0

2.0; the women's 100 meters hurdles 0.4,400 for the 0.3


2.0 m column. The standard model of elite athletes the basic Ibid.

2. Specific Performance: It is a special technical level of athletes, special qualities and special ability to the level of overall performance. After a period of training, specific performance strengths and weaknesses and the level of increase, a direct reflection of the special athletes can be trained sexual development potential, is an important indicator of selection. Should pay attention to training and competition for athletes to track performance observation, and its specific speed and specific achievements of progress to improve the quality of the relationship between the speed of analysis and comparison.

Height: there is no material impact on the sprint performance, different height of athletes in the sprint has achieved good results. But from an overall perspective, high-level athletes who are mostly taller. According to the information at home and abroad, "Outline" height to make the following criteria: the men's 100 meters, 200 meters athletes and 175 ± 5 cm, men's 400 meters athletes for 180 ± 5 cm; the women's 100 meters, 200 meters athletes and 165 ± 5 cm, women 400 m athletes and 170 ± 5 cm, as well as various stages of selection should be made to reach the height of the corresponding requirements. For the shorter people with special athletes can not be ignored.

2. Than the size of the legs [leg length / (calf length full high) × 100]: a relatively short legs, can run when the supporting phase center of gravity forward speed, big leg swing fast and effort before folding. Quite a long time calf, in the angular velocity of the same circumstances, "pawing" faster will help support the buffering action and shorten the completion time support. Therefore, the ratio of the size of leg length should strive for smaller requiring ≤ 100%, preferably ≤ 95%.

3. Than the ankle Wai (Wai ankle / Achilles tendon length × 100) and compared with the Achilles tendon length [Achilles tendon length / (calf + foot high) × 100]: Wai smaller ankle, Achilles tendon quite a long time, calf muscle strength greater Good speed and power. Thus, more than ankle-Wai should strive for smaller (≤ 100%, preferably ≤ 95%); than the Achilles tendon length should strive for bigger (≥ 50%, preferably ≥ 55%).

(B) the physiological function

sprint exercise time is short, strength, energy consumption per unit time is more demanding athletes are healthy and strong, and has a strong heart and lung function and anaerobic metabolism. Hemoglobin 12.0-14.0 g men over women, 10.5-12.5 g more than the vital capacity ≥ 75, stage index 105-115.

(C) dynamic performance and sporting qualities

1. Dynamic performance: Analysis of the world's best sprinters of the campaign experience found that most of them in the 13-18 age of special training, to achieve the best results at the age of men aged 25-26, women 23-25 years old, to achieve the best results need to use 8 -9 years of training, and initial results are generally higher. Achievements and progress in the early sprint speed reflect the innate ability and sprint sprint given potential, is a sprinter in the intuitive and objective selection of an important factor.

2. Campaign Quality: sprint performance depends on speed, speed, power and special endurance, these qualities and Genetic close selection test is the focus. The former Soviet Union researchers through the years of research, that under the system, the quality of the training year and a half growth forecast for the accuracy of the higher potential for sprinters.

(4) sprint technique

a reasonable way to run stride technology is open, frog stretch powerful swing positive, stride frequency faster, easier movement, forward good effect, the focus of stability, maintaining an appropriate forward torso, arm positive strong, straight-line running is good. According to sprint technical characteristics, the following three indicators.

1. Support Time: excellent sprinter sprint away from the fulcrum when the tread particularly fast (about 0.08-0.09 seconds), flight phase longer, which is a predictive bio-mechanical properties.

2. Stride frequency index (100-meter run average number of steps per second × height): studies have shown that stride frequency in the growth and development period does not change because of age, step-frequency index of the high growth portable larger, outstanding sprinter in this index in the High (≥ 7.4-8.1)

3. Stride index (an average stride length 100 meters ÷ Height): growth and development period, stride length is increased with age increased. As the speed = stride frequency × stride, so with age, the speed increase is mainly stride growth. Studies have shown that stride into a geometric growth in general and the relationship between height, its index is often a constant. Best sprinter this index higher (≥ 1.07-1.24)

(5) Psychological characteristics of

reaction speed (in particular, to listen to - dynamic response, are conscious of the will of the actions and achievements in improving technology, have a good effect), speed feel good (an accurate estimate of their own Paosu, the proper allocation of power and flexibility in adjusting the speed), Czech Republic, and strong perceptual sensitivity (increased movement frequency and the psychological premise of improved technologies), and the "want to run very soon," a strong desire is an excellent an important psychological characteristics of sprinters. Through a simple reaction time, start reaction time, perceptual speed of 50 meters, 100 meters to anticipate the speed and frequency of foot posture and other indicators to determine. Start reaction time (ms) for male 210, female 234, auditory reaction time for male 268, female 225, kinesthetic time error rate for men and 13.99%, female 14.69%. 100 meters to estimate in advance the error rate of 1.14% rate of both men and women, sitting a springboard for men and 55.45 times for 5 seconds, female 51.30, which can be used as material selection and evaluation of psychological Sprinters reference.

is also quite suitable for line

you still long, a long point on the better

me if you have a special 100 meters

I 178, the fastest 100 meters hurdles technology moves too 10.9

Anyway, also, I not suitable for one is not enough

hurdles Liu Xiang, the yellow race of people


Anyway, after all, in regard to the technical movement is too Mody Machine
