Invention of a device aimed the training of the handling of the hockey stick (stick Handling) by strengthening pronator and supinator muscles of the hand, allowing the improvement of the control, the rapidity of execution, the strength and especially the good technique of handling a hockey puck. This device is meant to isolate the movement of the dribble of the puck by the hockey player, to strengthen it and refine it.
The movement of pronation-supination is hardly detectable and measurable by a coach's eye. This movement is short, fast and with high amplitude mainly contributing to the rapidity of the dribble as well as the shot in ice hockey. Usually, the education received the technique or the tool (device for exercise) that will use the hockey players for practising puck dribbling refer to a movement of flexion-extension of the arm which is a non-optimum technique in the practice of the dribble in ice hockey. The movement of flexion-extension is considered in terms of biomechanics as a coarse movement mainly used to generate brute force instead of performing a movement of great precision. Therefore, when a player makes a movement of flexion-extension of the arm in order to perform a dribble, he can hardly control the amplitude of the latter while generating a high speed, a essential quality to perform an efficient dribble. By contrast, a dribble by pronation-supination of the forearm allows to meet these requirements thus getting a dribble of quality well above.
The device is designed mainly to isolates the movement of pronation-supination allowing young and older, gifted or novice, professional or amateur to identify the exact gesture to perform for a puck dribble and refine it. Thus, the movement of flexion- extension of the elbow is avoided, a common mistake among the hockey players. Moreover, once the movement of pronation-supination is well assimilated, it allows the quality improvement of the dribble expressed by the increase of its rapidity of execution, of the force deployed or both simultaneously.
Once the movement is isolated, the device offers a variable resistance which allows targeting certain essential muscles for a dribble and strengthening them. To properly control the amplitude during the movement, a sound device warns the user and allows him to control precisely the degree of pronation-supination necessary to achieve the maximum amplitude according to the human biomechanics. More in details, a supination at 90 degree and a pronation at 85 degree both starting from the zero position respectively describe the maximum amplitude. When each position are reached, an audible as well as a light signal indicate simultaneously the user that the maximum amplitude is reached and immediately inform the exact moment to change the direction of the movement. The total amplitude of movement is 175 degree around a longitudinal axis.
Of course, the device distinguishes itself from other devices who work the flexor and extensor of the wrist which are of different muscles. It is noteworthy to mention that mostly of these muscles do not cross the wrist joint Therefore; they are rarely solicated during movement of flexion-extension of the wrist. However, they are extremely solicited during rotation of the radius on the cubitus since their origins and their inserts are located on these latter. Since they are very short, these latter contribute predominantly to the speed deployed during the dribble.
Few inventors have designed a device working on the techniques to use during a dribble. Moreover, these same techniques did not allow an effective training of a dribble since they do not involve the movement of pronation-supination. In addition, none has combined in a single device nowadays an apparatus used to assimilate the proper technique as well as to strengthen the solicited muscles during the motion. Even now, there is no such device that has a guiding system based on sound and visual warnings on the efficiency of the movement and a system of resistance. (CA 2642520)
Our invention combined all the elements above in an all-in-one device. It allows the user to learn the correct movement of the dribble, to strengthen the solicited muscles to this movement and to refine its accuracy.
