Track And Field Sports In The Special Physical Training Of Long Jump Method Research

Long jump sports belong to the projectile motion, we according to the movement ofthe far degree formula S=v2sin2a/g, Mass ejection far mainly depends on the initialvelocity and mass ejection Angle, although the long-jump than with a mechanicalmovement are exactly the same, but they follow the rule is the same. Far degrees afterso long jump athletes takeoff performance depends on its takeoff to complete themoment of takeoff speed and Angle. However, players of the level of the final stagesof run-up speed and take-off Angle and the vertical velocity is decided to leap a tengspeed at first.[9] so according to this law, the athlete must ensure that the premise inthe high-speed run-up, efficient attempt to obtain suitable Angle. The developmenttrend is very obvious. The lacks of any factors are unlikely to succeed. From theperspective of sports biomechanics to analyze, Run-up speed depends on two aspects,One is the absolute velocity of athletes; The two is the utilization rate of absolutespeed athletes run-up process. And the angle are mainly decided quickly kicking inathletes and stretching ability, namely the athlete "s fast strength ability. The formerSoviet Union scholar B#bIIOIIB thinks: the movement of the external state(kinematics) and internal mechanism (dynamics),In terms of the number of significant relationship is close0. Show that the causalrelationship, if the speed and strength quality athletes do not have a high level of longjump, so he could not very good improvement of technology and improve athleticperformance. Special physical factors so decisive effect to the performance of longjump athletes from the special speed, the rapid strength athletes. Through theoreticalreasoning, both at home and abroad as well as the results of the regression analysis ofthe data analysis of competition of elite athletes in recent years, we see not hard, longjump athletes to achieve the excellent sport achievement goal, must have perfectrun-up and take-off ability, can best embody the special physical fitness indexes intwo aspects ability is special speed athletes and special fast take-off ability, Andspecialized speed ability to obtain athletes have a higher absolute speed level asreserves, speed and strength rapid take-off ability require absolute power as a reserve,so long jumpers must be absolute velocity and absolute strength training as the basis,to the development of athletes specialized speed ability and special ability of fasttaking-off special physical ability training as the core. Ensure that the athletes achieveexcellent performance on the premise of.We can see that the analysis of the take-off process: athletes do in the moment oftake-off leg work is composed of centrifugal rapid transition to the concentriccontraction work, and in order to achieve rapid take-off effect, we must quickly endthe centrifugal contraction pedal instantaneous muscle and rapid transition to thecentripetal contraction stretching work. So in the process of rapid strength training,should focus on the take-off leg eccentric and concentric contractions alternating fastswitching action, such practice is mainly to improve the take-off leg muscles bypassive stretch to quickly convert active contraction ability. So start off the leg to thefastest speed buffer action of contact with the ground and start kicking was the best take-off vertical velocity and horizontal speed, improve take-off effect. Athletes inorder to adapt to the high intensity of game, to achieve external performance througha variety of methods for training (special technical actions) and the internalmechanism (physical quality) of the perfect combination of. So in the process oftraining, to effectively improve the quality and efficiency of physical training,especially for the special physical ability training. Choosing the reasonable trainingmethods is an important factor affecting the success or failure of training. Thephysical ability training method must accord with human body physiological,biochemical, biomechanical characteristics and combining with the characteristics ofindividual athletes. The most important thing is to be in the physical training hasalways adhered to the "implementation method combined with practice, meet thespecial requirements and special characteristics of athletes and means" to thisprinciple, we can effectively improve the sport achievement...
