Description

  The present invention relates to a training system comprising a training device for use by athletes to improve footwork agility and upper body creative exercise. Such devices are often used in athlete training courses and can be used in combination with music or rhythm sounds to help athletes maintain a particular rhythm.

  This training system provides athletes, coaches and conditioning professionals with innovative and dynamic training systems in the technical philosophy rather than just training aids. By using this comprehensive training system, athletes can coordinate (muscle movement coordination), self-acceptance (be aware of their own position in relation to the external environment, Position sense, etc.), rhythm and balance can be developed and kinesthetic feedback can be obtained through the use of movement patterns such as dance, thereby identifying footwork and upper body creative movements or It is possible to promote improvement in the overall field.

  This system can integrate dedicated exercise patterns and training drills (practices) for a particular sport selected. This training system alleviates the difficulty of performing footwork and upper body creative exercises and dance drills during normal training courses by providing a training device that is a "perfect training system by itself" Can do. In addition, this training system should be used as an aid to other training devices, systems and methods such as pliometrics (muscle training method that repeats exercises that stress muscles at once, muscle tension method), core stability and reaction training. It has the flexibility to be able to.

  This device and system can be incorporated into any stage of physical conditioning of a team or individual. This training system can be used as a system to improve foot movement in new or complex skill training. The device and system can also be used as part of a core training program by overloading a physiological system that current training systems cannot normally tension. This is because coaches require special complex scenarios that require more than just repetitive regular training runs and require excessively time-consuming preparation for numerous teaching setups. . This training system is also designed for rehabilitation of individuals or athletes after injury. This training system provides a step-by-step personal approach for any rehabilitation program, and it has been critical that it has been left alone or difficult to implement without a separate specialized training system. It is possible to configure so as to improve the physiological adaptability (such as sensory organs). This training system enhances the content of rehabilitation programs by focusing on the development of muscle dynamic footwork and upper body creative movements for the purpose of redeveloping elements such as coordination, self-acceptance, rhythm and balance. .

An example of an apparatus for training and practicing athletes is disclosed in US Pat. No. 6,477,427. However, this device has a number of drawbacks, especially when considering the stability of the device in use and the resilience to unexpected impacts.
US Pat. No. 6,477,427

  In this known device, a bar-like cross rail is used to prevent the inelastic flexible railing (generic name for guardrails, fences, handrails, etc.) from being removed during use. Is relatively unstable and easy to move when an athlete hits it. When this device is connected to a pile and fixed, the pulling string may be connected to the railing via a snap connector so that the ladder of the device is disconnected from the pile when subjected to excessive force. it can. However, this device is very inconvenient to use because it is unstable when placed simply on the floor. On the other hand, when the device is fastened to the pile, the above-mentioned “separation” means must be provided. Moreover, every time “disconnect” occurs, the devices must be reconnected, which is extremely inconvenient. Furthermore, the only tethering mechanism recommended is to stake on the ground, which is unsuitable for indoor use.

  This known device has crosspieces that are substantially parallel to each other, but it turns out that repeated drills (exercises) are not beneficial to athletes and can be harmful. is doing.

  According to the present invention, a training device for use by athletes to improve footwork agility, comprising two elastic cords each spanned between two weights, and the two There is provided a training apparatus having a ladder assembly (ladder-like structure) composed of a plurality of cross rails spanned between elastic cords.

  This device makes it possible to form a ladder from a large number of crosspieces attached between two elastic cords. As the elastic cord, for example, a cord having elasticity can be used. Also, the use of a weight allows the device to be used both indoors and outdoors, since no soft ground is required to tether the device. The use of elastic cords means avoiding the need to provide means for separating the ladder from the anchor (tethering means) when subjected to an impact.

  Furthermore, by using the present invention, as will be described later, it is possible to create a large set that is stable and can be restored to its original form by itself even if an athlete hits or kicks. .

  It is advantageous if the means used to attach the crosspieces to the cord allows the crosspieces to be attached to any part of the cord. In that case, the ladder assembly can be configured in such a manner that the interval between two adjacent cross rails is variable.

  Each crosspiece can preferably be mounted in two different orientations with respect to the cord so that the angle between the cord and the crosspiece can be, for example, α or 180 ° −α. In that case, a very wide range of different forms of ladder assemblies can be formed by attaching each of the cross rails arranged in sequence in one of two directions.

  As detailed later, this means that each time an athlete performs a drill, the path taken to the device is slightly different, so the athlete repeats the same drill. Does not suffer from harmful effects.

  In a preferred embodiment, the horizontal rail is configured such that the horizontal rail can be attached to the cord by passing the cord through a hole formed at the end thereof. This hole can be drilled at an angle other than 90 ° with respect to the longitudinal axis of the crosspiece.

  At both ends of the cord, hooks that engage with a ring (eyelet) provided on the weight can be provided. However, a ring or eyelet may be attached to the cord and a hook may be attached to the weight. Each weight is preferably provided with a number of cord attachment means (rings or hooks) so that additional ladder assemblies can be attached to its various locations.

  When four attachment means are provided at equal intervals on each weight, it is possible to form a set in which a plurality of ladder assemblies are arranged in a square or rectangle.

  Embodiments of the present invention will be described below by way of example with reference to the accompanying drawings.

  Referring to FIG. 1, a ladder assembly 1 according to the present invention includes four weights 2 and two stretchable cords (hereinafter referred to as “stretchable cord” or simply “cord”). 3. Each cord 3 is attached to two weights 2 by hook and eyelet assemblies 4a and 4b. In this specific embodiment, hooks 4 a are provided at both ends of each cord 3, and eyelets 4 b for engaging the hooks are provided at each weight 2. A plurality of horizontal rails 5 are bridged between the two cords. Holes are formed at both ends of each horizontal rail, and the horizontal rail is attached to the cord by passing the cord through the hole. The horizontal rail 5 can be held at a predetermined position by the toggle 6 (see FIG. 4), but other fixing means may be used. Usually, the ladder assembly is provided with about 16 horizontal bars, but for the sake of simplicity, a smaller number of horizontal bars are shown in the figure.

  The cord used in the present invention is called an elastic buffer rubber cord having a diameter of 8 mm, which is a natural rubber covered with a polypropylene yarn cover and has a stretchability of 140% ± 10%.

  The weight 2 is made of steel to provide stability to the device during use, but any other suitably heavy material can be used. Field tests have shown that a weight of 11.5 kg is particularly effective. In combination with the elastic buffer cord described above, a ladder of up to 9.8 m can be assembled.

  The weight 2 can also be formed from a heavy plastic material by molding or other methods. In a preferred embodiment, the weight 2 is encapsulated (encapsulated) with rubber in order to obtain a traction friction force (anti-slip action) and a protective action against the floor. These weights are formed with female and male surfaces so that they can be easily and safely stacked.

  As another embodiment, the weight 2 can be seated on a rubber mat to obtain traction friction and floor protection. The crosspiece 5 is manufactured from a molded plastic tube and can be provided with a reinforced inner wall of aluminum.

  The elastic cord and the plastic crosspiece have the advantage of being weatherproof.

  FIG. 2 shows a preferred embodiment of the weight 2. FIG. 3 shows a preferred embodiment of the crosspiece 5. The crosspiece 5 has an end cap 7 for protection. An alarm device (in the preferred embodiment, a buzzer) that issues an audible alarm when an in-use athlete hits a side rail can be incorporated into the end cap. The alert provides feedback regarding the accuracy of the athlete's footwork during practice. The alarm can be switched off if the device is being used by many athletes at the same time.

  Figures 5a and 5b show a hook 4a according to a preferred embodiment of the present invention. This hook is designed so that it can be clamped in place through a cord around it.

  The length of the ladder can be easily changed by releasing the cord from the hook, sliding the hook along the cord, and re-clamping the cord to the hook at the desired location. The weight may be repositioned to fit the shortened ladder length. If necessary, you can remove some of the side rails as long as they are shorter.

  Referring to FIG. 6, a preferred embodiment of a ladder assembly is shown in schematic view. At both ends of each horizontal beam, a hole is formed at an angle with respect to the longitudinal axis, so that the horizontal beam can be attached to the cord in one of two directions. It has been made possible. In the embodiment shown in FIG. 6, one crosspiece 5a is oriented in one direction so that the angle between it and the cord 3a is α, and the adjacent crosspiece 5b is connected to it and the cord 3b. Is oriented in the other direction such that the angle between the two is 180 ° -α. In FIG. 6, each horizontal rail is assembled so that adjacent pairs of horizontal rails have different directions. Even if the holes at both ends of the horizontal beam are drilled at an angle of 90 ° with respect to the longitudinal axis, there is a margin of allowance, so the horizontal beam should be arranged at a slight angle with respect to the cord. Note that is possible.

  However, when the hole is drilled at an angle of 90 °, two problems are encountered when the rod (lateral beam) is moved to an oblique position. That is, since the 90 ° hole does not adapt to the diagonal position of the rod, it is very difficult to move the rod, and once it is directed to the diagonal position, the railing (cord) is distorted, and in a straight line Not a zigzag line.

  The form of the ladder is different each time the ladder is set up, for example, because there is a slight difference in the distance between the cross rails. Differences in the form of the ladder that occur at each set-up are very important in adapting to different situations, rather than having the same movements follow exactly each time, in training an athlete. Toggle can be used to temporarily fix the crosspiece in place. A press release mechanism allows the crosspieces to be easily repositioned as desired during training.

  FIG. 7 shows a ladder assembly that is configured differently by arranging several of the adjacent crosspieces, for example, the crosspieces 5c and 5d in the same orientation. Thus, it will be appreciated that numerous different configurations of the ladder assembly are possible by changing the orientation of the side-by-side rails. Further, in certain embodiments of the present invention, the angle of each side rail or some side rail holes may be different from the angle of other side rail holes.

  FIG. 8 is a diagram illustrating one advantage of the ladder assembly of FIG. 7 over the ladder assembly of FIG. That is, if the athlete moves along the path A, B, or C on the ladder assembly of FIG. 7, they can move along different paths. On the other hand, in the ladder assembly of FIG. 8, the paths A, B, and C are all the same. This advantage of the ladder assembly of FIG. 7 is obtained by attaching the crosspiece to the cord at an angle other than 90 °.

  The fact that the crosspiece is attached to the cord by passing the cord through the hole at the end means that the crosspiece is slid along the cord to various interiors in order to freely change the interval between the adjacent crosspieces. Means that you can. 9a and 9b show the holes in the cross rails through which the cords pass. The crosspiece can be held in place with respect to the cord using one or more toggles 6 as shown in FIG.

  FIG. 10 shows an embodiment in which three ladder assemblies are formed in a U shape and the fourth side of the inner square is formed by a single cord. This use of a single code makes it possible to incorporate multiple footwork patterns as routines around a straight line. Larger forms suitable for group or group practice can also be created.

  Such cascading of multiple ladder assemblies is made possible by providing multiple attachment means for each weight so that one or more ladder assemblies can be attached to a single weight. The ladder assemblies can be cascaded as shown. As will be apparent to those skilled in the art, any number of ladder assemblies can be assembled into a training system, for example, rectangular, square, or U-shaped with one side connected by a cord, or L-shaped. FIG. 11 shows an example in which two ladder assemblies are combined in a straight line.

  It would be advantageous if additional obstacles could be added to the training exercise.

  12, 13, 13a and 13b illustrate obstacles that can be attached to the training device described above. Figures 13, 13a and 13b show a conical member 8 which can be attached to a cross rail as an obstacle that the athlete must pass through. FIG. 12 shows a hurdle 9 that can be used in combination with or as an alternative to a conical member. The clip 10 facilitates the attachment of these obstacles to the cross rail.

  The inherent stability of this device allows such obstacles to be clipped to the crosspiece. None of the conventional devices can provide the required stability. In the present invention, a very stable system capable of attaching such an obstacle is provided by using a weight in cooperation with the elastic cord.

  The training device of the present invention can be installed directly on any floor or grass. For athletes trying to recover from injury, the device can be used on a cushioned mat.

  The device of the present invention is assembled by passing a series of crosspieces through two cords and then tensioning (stretching) each of the cords between two weights. Then, the crosspiece can be slid to a required position and held in place using the toggle as described above.

  The main factor that determines skill acquisition is psychomotor ability. Psychomotor refers to a technique that involves both physical movement (“motor”) and mental (“psycho”) elements. To develop psychomotor skills, it is necessary to consider perceptual skills, self-acceptance skills, and physical movement skills.

  Perceptual skills include reading the situation and recognizing the effects of other players.

  The sense of balance is sometimes referred to as self-acceptance in order to reflect not only balance but also a greater sense of position recognition. The sense of balance depends on information from the human eye, inner ear and somatic receptors (in the joint capsule, ligaments and muscles). Information from these sensory receptors travels to the brainstem and cerebellum regions of the brain where they are organized into spatial recognition. Humans can use this information to coordinate (coordinate) movements as a smooth sequence of movements.

  Physical exercise techniques include all voluntary movements of muscles in the correct order. However, this relates not only to the muscle that directly controls the desired exercise, but also to the posture-maintaining muscle that allows humans to maintain an upright posture and be able to coordinate the exercise and thus Also related to needing information about self-acceptance.

There are three aspects to learning psychomotor skills. That is,
1. Early or cognitive phase This is a phase in which humans learn each stage of a task, for example driving a car. At first there is too much information, so speed is important. If the speed of work is slowed down, the information that must be processed at that time becomes less and learning becomes easier.
2. Linking or operational aspects In this aspect, reactions are linked to appropriate stimuli. For example, learning one line of a poem triggers you to go to the next line. In contrast, it is much more difficult to recall and quote the line before the last line, and when requested, to recall the requested part, the entire poem is in your head. Read through. Thus, each line in the poem is a trigger to remind you of the next line.
3. Automatic response As control is taken over by the lower central part of the brain, tricks become more automatic. Acquisition of the physical motor order initially involves activation of the motor cortex and cerebellum, but the acquired motor order, referred to as the neural pathway, is probably somewhere else, possibly the striatum. There is a certain proof that it exists in the cortical network. At this stage, exercise performance is smooth and automatic. Thus, psychomotor is retained as a complete program or a neural pathway. Rhythms developed using music in the chain phase are embedded in the body during this automatic reaction phase, and athletes are not cue from outside (cue, trigger) to time their reaction, Gradually become dependent on your internal queue.

  It is clearly useful for athletes to repeat exercises until they become implanted in the body as a neural pathway that can be called when needed. Use this procedure many times. For example, a tennis player can practice backhand repeatedly. Unfortunately, however, footwork is an essential component of most sports, although much attention is not paid to footwork in many training regimens. A football player who cannot avoid a defensive player will probably not be able to play in the second half due to injury. Even if a tennis player has a complete backhand technique, the technique cannot be used unless the body can be brought to the proper position on the tennis court. It is possible to use footwork that naturally occurs when playing a particular sport, and to rely on regular training to produce sufficient practice. This is the way most footwork training has been performed in the past, but the training system according to the invention makes it possible to implement an improved method.

  Although the invention has been described above by way of example in connection with embodiments, it should be understood by those skilled in the art that various changes and modifications can be made without departing from the scope of the invention.
