Description
Technical field
The utility model belongs to the Motion Technology instrument field, relates to training of muscular strength and explosive force and diagnostic system.
Background technology
Muscular strength and explosive force are the deciding keys of competitive sport in modern age, do not have remarkable muscular strength and explosive force almost to be difficult to survive in competitive sport with keen competition.In the very violent competitive sport of many competitions, want to strive for one seat, muscular strength and explosive force are the key physical efficiency key elements of success or not, it also is the training problem that coach, sportsman suddenly desire seeking breakthrough and development, therefore, for effectively lifter motion performance, the training method that coach and countless sports science man are devoted to seek effectively to promote muscular strength and explosive force invariably, the while also construction the training theory of many muscular strengths and explosive force.
(weight training is exactly the main means that are used for training muscle strength for a long time WT), also is considered to promote the effective ways of maximum muscle force in weight training.Yet many studies show that though weight training can effectively be promoted muscle strength, is not enough to improve dynamic motion performance (Fry ﹠amp; Kraemar, 1991), even can produce restrictive function (Bloomfield et al, 1990) to responsiveness, and then limited the development of explosive force.
The target that modern competitive sport is pursued is higher, faster, farther, and according to kinematic principle, these targets are determined by speed, and according to momentum theorem, speed is determined by linear impulse again.Though the key player who promotes muscular strength is still being played the part of in traditional weight training, as if can't satisfy the sports demand of modern height pursuit speed and explosive force.In the sports, the power of muscle is called explosive force, explosive force is strength and function of speed, therefore, in order to promote the competitive sport performance, meet the demand of most of dynamic motion performances, except the training of maximum muscle force, the training of necessary consideration speed aspect can reach the purpose that promotes explosive force and sports performance.
In order to adapt to the dynamic athletic performance of great majority, make training more approach actual competitive state, developed again afterwards the excess of export isometric training (plyometrics training, PT), as the means that promote responsiveness and explosive force.Superfine long training is a kind of muscle of tractive in advance (prestretch), makes muscle become the passive elongation of centrifugal contraction, forces the final entad contraction phase can produce a kind of explosive force training method (Kritpet, 1989) of more powerful contraction.The advantage of this training kenel shows (Schmidtbleicher on stretch reflex (stretch reflex) characteristic that makes full use of elasticity of muscle energy (elasticenergy) and excite muscle, 1992), its training goal is to link strength of action and responsiveness, to produce the action kenel of sending out sexual reflex effect (explosive-reaction) wink, it often is used to refer to jump dark training (depth jump), also can contain any muscle stretch reflex characteristic of utilizing of lid, to produce the training kenel (Chuand Plummer, 1984) of sending out the sexual reflex action wink.This training method is mainly that in conjunction with speed training and strength building in the hope of increasing explosive force, its purpose is in order to produce the summation of maximum strength in the shortest time.In recent years, superfine long training extensively is subjected to coach's welcome, and this training method is combined sport skill training, is widely used in the Modern Exercise Training course, and obtains good training effect (Komi, 2003).Need the sports events of powerful explosive force at some, for example basketball, vollyball, sprint race, jumping, throwing and gymnastics etc., superfine long training also is considered to necessary training tool.Cai Fengren, Liu Yu (1998) once was trained for means with the dark jumping of controlling fast increment and control amount speedup, implement to be total to the quantitative control mode of superfine long training load in eight weeks by a definite date twice weekly, the result shows: the vertical jumping of two experimental group has improved 7 centimeters and 7.8 centimeters respectively, the responsiveness progress 10.26% and 10.52%, the explosive force progress 10.72% and 10.23%, but with Squat Jump is that the dynamic maximum muscle force value of testing means is not showing and changes, and, the effect of the explosive force lifting that is caused is that therefore training method has promoted responsiveness but not strength of action.This research has illustrated that superfine long training is very helpful on enhancement explosive force and responsiveness, but for the development of maximum muscle force its restriction is arranged.This research is also advised: superfine long training is if can develop explosive force in property ground more comprehensively in conjunction with weight training.The research of Adams et al (1992), relatively traditional squat weight training in six weeks, superfine long training, squat weight training are in conjunction with superfine long training, three kinds of different training methods promptly show the explosive force Influence and Development: in conjunction with weight training and superfine long the training compared with the mode of carrying out weight training or superfine long training separately, more can effectively promote explosive force and vertical jumping ability.
In order to promote responsiveness and explosive force in conjunction with superfine long training, and weight training can promote the two-fold advantage of maximum muscle force and explosive force, and remove possible shortcoming, researched and developed a kind of Plyometric of being called Power System (Plyopower Technologies system at present in Australia, Australia) training aids, carry out so-called superfine long weight training (plyometric weight training), this training method mainly is to utilize similar Smith's training aids (Smith Machine), the bullet shake formula of bearing a heavy burden is squatted and is jumped (weightedballistic jump squat) or the superfine long lower limb explosive force training of squatting and jumping (weighted plyometric jump squat) of bearing a heavy burden, and also can have or not counteragent (with or without countermovement) to lie on the back and push away the upper limbs explosive force training of throwing (bench press throw).This is a kind of special high speed motion under suitably bearing a heavy burden, emphasizing must fast and not have the retarding braking phase at whole entad Syst course of action, and will people from the company of load is with thick stick to push off ground (loading by lower limbs is squatted and jumped) or weight is thrown out from hand (upper limbs is lain on the back to push away and thrown) in latter stage entad.More existing researchs have verified that the superfine long training of bearing a heavy burden comes much betterly (Newton, 2005) to the effect of vertical jumping explosive force than simple superfine long training or simple high-drag weight training.
Research also shows the floor press (bench press) of traditional type and lies on the back to push away and throw (bench throw) difference in responsiveness and strength output, lie on the back to push away and throw because of there be not the retarding braking process to heart stage, responsiveness presents more and more faster result, and strength also remains on relative high level with the momentum value, therefore, lie on the back and push away the development of throwing better effect is arranged explosive force.
Aspect the optimum load of crouching jumping that bears a heavy burden, the research of Wilson et al (1993) is pointed out: maximum (the maximal voluntary contraction that arbitrarily shrinks with 30%, MVC) load is trained, can obtain the increase of maximum explosive force, this research is also found simultaneously: the heavy burden crouching jumping training with 30% MVC is best to the effect of vertical jumping performance.The research of the research of Dugan et al (2004) and Newton (2005) is pointed out: for trained player, bear a heavy burden with 30% of maximum isometric muscle force MVC and squat to jump training, the explosive force peak value of exportable maximum, loading to train with this to obtain best explosive force training effect; But for the relatively poor experimenter of the level of training, the load of 10%MVC can produce maximum explosive force value on the contrary, therefore, should decide according to the athletic level of training when selecting load.
The discussion of research background as can be known more than comprehensive: maximum muscle force can be effectively promoted in weight training, but is not enough to change dynamic athletic performance; And superfine long training can effectively promote responsiveness and explosive force, but the development of maximum muscle force is had its restriction.
Though above-mentioned training method can increase strength and explosive force performance, still, the sportsman carries out superfine long training under the situation of bearing a heavy burden, and the impulsive force on the weight of barbell and ground when landing does not have the negative effect of being suspected to have to athletic safe and psychological aspect.
