Description

Force baseball

This creation relates to a force-measuring baseball, especially a finger strength signal that can wirelessly monitor and display the trainer's pitching.

Baseball is a teamwork sport that combines four techniques of "pitching, striking, running, and defensive". It consists of two elements: defensive (pitching and defensive) and attack (strike and run). There are many factors that need to be matched to win a baseball game. The key to winning the game is the pitcher. It is generally considered that the pitcher's performance is 70% of the game's outcome (Gao Yingjie, 1996; Ye Zhixian, 1997).

A good pitcher has the ability to have fast ball speed, good ball control, diversity change ball and smart ball-matching strategy (Ye Zhixian, 1997), in which the pitcher has the diversity of the ball is the basis of the ball, the common ball There are a fastball, a curve ball, a slider, a cutter, a sinker, a folk ball, a change up, and the like. According to the change pattern, it can be roughly divided into three categories: the lateral displacement change sphere, the longitudinal displacement change sphere, and the speed difference change sphere (Gao Yingjie, 1996; Yang Xianming, 1996). According to the throwing method, it can be divided into (1) The method of changing the finger holding the ball, (2) using the elbow, the rotation of the wrist, (3) or the combination of the two, the fork ball and the shifting ball are basically summarized as changing the ball of the grip method, and the card is extended. It is summarized as a change ball that uses the elbow to rotate. The curved ball, the sliding ball, the cut ball, etc. are summarized as the change balls that use the changing grip method and the elbow rotation (Gao Yingjie, Jiang Kunda, 2008).

Past studies have found that pitching techniques have significant differences in kinematics, kinetics, and degree of muscle activation when throwing different types of balls (Elliott & Glove, 1986; Sisto et al, 1987; Escamill et al, 1998; Fleisig et al , 2006), and pitching performance is related to muscle strength, pitching technique, pitching motion characteristics, etc. (Fleisig et al, 1999; Stodden et al, 2006; Mangine et al., 2013); recent studies have found that whether it is a straight ball or All kinds of change balls mainly depend on the wrist joints, the finger gripping method and the finger changes at the moment of pitching, causing the sphere to rotate in space to produce the Magnus effect, which causes the ball to change (Yang Changzhan, 2006), so the pitcher's finger movement and strength Size, playing a very important role in the throwing process, related to pitching accuracy and sphere flight trajectory (Hore & Watts, 2005), especially before the ball leaves the hand, giving the ball more power to accelerate and produce the ball Higher speed rotation for greater lift and Magnus force, which allows the sphere to fly faster and change more trajectories (Sakurai & Hirano, 2011). Sakurai & Hirano (2011) A study of the straight ball thrown by 19 baseball pitchers found that the axis of rotation of the ball is determined by the fingers and palms, and is related to the angle of the palm before the hand and parallel to the palm of the hand, so if the ball is to produce maximum lift When the ball is off the hand, the palm must face the home base direction, and the rotation axis of the sphere must be parallel to the ground. Therefore, the strength of the finger is one of the important factors affecting the pitching speed and the trajectory of the change.

However, in the current baseball-related technology, most of the baseball structure and baseball material are used, and there is no sphere for the baseball player to measure the finger strength of the pitcher to improve the performance of the pitcher and prevent sports injuries.

In addition, the conventional baseball pitch training method is when a pitcher is practicing in the pitching practice, and another pitching coach stands by the pitcher to observe, and the pitching teaching is carried out by the experience of the pitching coach. Some coaches will use more than one coach. The high-speed camera photographs the pitching process of the pitcher, and then uses the slow-motion playback mode to judge the position of the pitcher to judge the problem that the pitcher has to correct; however, the conventional baseball pitch training method cannot know the finger force of the baseball in the pitching process. The situation, the degree of finger fatigue, the force and force generated by the application of the ball, and the training methods and assessment tools for finger muscle strength, etc., so that baseball pitch training is less effective.

Therefore, the main task of this creation is to develop a force-measuring baseball, in order to measure the strength value of the pitcher's fingers on the sphere during the pitching process, as well as the finger fatigue monitoring during the pitching process, and also as a finger strength training. Use, to provide measurement of finger strength, power value feedback during finger training, finger force measurement, etc.

The signal processing control circuit is electrically connected to a signal transmitting unit and a power module, and the baseball surface is provided with at least two signal detecting units, and the second signal detecting unit is respectively connected to the signal processing control circuit. The sexual connection is used by the second signal detecting unit to measure the finger strength (pressing) value, and the signal processing control circuit receives and processes the finger power value, and then the signal transmitting unit transmits the finger power value signal by wireless transmission; the signal The receiving device is configured to receive the finger strength value signal, and the signal receiving device is provided with a screen for displaying information of the finger strength value signal.

The technical feature of the present invention is that the baseball surface is provided with at least two signal detecting units for measuring the finger strength (pressing) value, and then used in the baseball to have a signal processing control circuit and a signal transmitting unit; when the training personnel When the ball is pitched, the finger strength value signal measured by each signal detecting unit is transmitted to the signal processing control circuit for signal processing and calculation, and the processed and calculated finger strength value signal is transmitted through the signal transmitting unit. The wireless method is sent to an external signal receiving device, and the signal receiving device performs data display and monitoring of the finger power value signal, thereby achieving the force value applied by the pitcher's fingers on the sphere during the pitching process, and the finger fatigue during the pitching process. Monitoring, at the same time, can also be used for finger muscle strength training, providing measurement of finger strength, strength value feedback during finger force training, measurement of finger fatigue degree, etc.
