Description

Sensing baseball

The invention relates to a sensing baseball, in particular to a signal capable of wirelessly monitoring and displaying the finger strength value of a trainer during pitching.

Baseball is a team-cooperating sport that combines four technologies: pitching, hitting, running, and defense. It consists of two major elements: defense (throwing and defense) and attack (strike and running). There are many factors to cooperate in winning a baseball game. Among them, the key to controlling the outcome of a game is the pitcher. It is generally believed that the pitcher's performance accounts for 70% of the game's outcome (Gao Yingjie, 1996; Ye Zhixian, 1997).

A good pitcher has the ability to have a fast ball speed, good ball control ability, diversified ball changes, and clever ball distribution strategies (Ye Zhixian, 1997). Among them, the diversified ball types are the basis of the ball distribution. Common balls There are fastball, curve ball, slider, cutter, sinker, folk ball, change up, etc. According to the type of change, it can be roughly divided into three categories: change ball in lateral displacement, change ball in longitudinal displacement, and change ball with speed difference (Gao Yingjie, 1996; Yang Xianming, 1996). According to the throwing method, it can be divided into (1) Change the method of finger grip, (2) use the rotation of elbow, wrist, (3) or the combination of the above two, etc. The fork ball and the shift ball are basically summarized as a change ball that changes the grip method, and the ball is stretched. It is summarized as a change ball using elbow rotation, curved ball, slide ball, cut ball, etc. are summarized as a change ball using simultaneous change of grip and elbow rotation (Gao Yingjie, Jiang Kunda, 2008).

Past studies have found that when throwing different ball types, the pitching technique has significant differences in characteristics such as kinematics, dynamics, and muscle activation (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, and pitching characteristics (Fleisig et al, 1999; Stodden et al, 2006; Mangine et al., 2013); recent research has found that whether it is a straight shot or Various changing balls mainly depend on the wrist joint, the way the fingers hold the ball and the finger changes at the moment of the pitch, causing the sphere to rotate in space to produce the Magnus effect, which changes the ball path (Yang Changzhan, 2006), so the pitcher’s finger movement and strength The size plays a very important role in the throwing process, and is related to the accuracy of the pitch and the trajectory of the ball (Hore & Watts, 2005), especially before the ball leaves the hand, the ball is given more force to accelerate the ball and produce Rotation at a higher speed produces greater lift and Magnus force, which in turn makes the sphere fly faster and change its trajectory more (Sakurai & Hirano, 2011). Sakurai & Hirano (2011) research on the straight ball thrown by 19 baseball pitchers found that the rotation axis of the ball is determined by the finger and palm, and is related to the angle of the palm before the ball is away from the hand, and is parallel to the palm, so if the ball is to produce the maximum lift At the moment when the ball leaves the hand, the palm must face the direction of the home base, and the rotation axis of the sphere must be as parallel as possible to the ground. Therefore, the strength of the finger force is one of the important factors affecting the pitching speed and the changing trajectory.

However, in the current baseball-related technologies, most of them are based on the structure and material of the baseball, and there is no sphere that measures the finger strength of baseball players to improve pitcher performance and prevent sports injuries.

In addition, the conventional baseball pitching training method is that when a pitcher practices pitching, another pitching coach stands beside the pitcher to observe, in order to rely on the experience of pitching coaches to teach pitching, some coaches will use more than one The high-speed camera shoots the pitcher's pitching process, and then the pitcher's posture is played in slow motion to judge the problem that the pitcher needs to correct; however, the conventional baseball pitching training method cannot know the force of the baseball's finger during the pitching process The situation, the degree of finger fatigue, the forward force and component force generated on the sphere, and the training methods and evaluation tools for finger muscle strength are not available...etc., so that the effectiveness of baseball pitching training is not good.

Therefore, the main subject of the present invention is to develop a sensing baseball to measure the force value exerted by the fingers of the pitcher on the ball during pitching, as well as the monitoring of finger fatigue during pitching, and can also be used for finger muscle training Use it to provide functions such as finger strength measurement, force value feedback during finger strength training, finger fatigue measurement, etc.
