Slow reaction time to catch a ping-pong ball
If the reaction speed is slow when catching a ping pong ball, you can improve it from the following aspects: ** 1. Focus and judgment ** 1. ** Increase concentration ** - Concentration was crucial in a table tennis match or practice. He had to concentrate on the trajectory of the ball and judge the direction, speed, and rotation of the ball. For example, in his daily practice, he deliberately trained himself to eliminate external interference and only pay attention to the movement of the ball. 2. ** Increase judgment speed ** - Judgment abilities included visual judgment, auditory judgment, experience judgment, and psychological judgment. Among them, the speed of judgment was especially important. A slow judgment would cause the subsequent actions to be slow. To improve the speed of judgment, one needed to observe the opponent from all sides, whether they were fighting on the field or watching from the sidelines. He had to remember the opponent's movements and the rotation, speed, and landing point of the incoming ball. For example, he had to remember what rubber the opponent used, what movements he made, how much strength he used, the location of the hitting point, the area where the ball touched the board, and other factors related to the rotation, speed, and landing point of the ball. He also had to remember how to receive the ball to make the opponent uncomfortable and help him prepare for the next board. He tried his best to elevate his visual judgment and hearing judgment to experience judgment, which was to improve his prediction ability. In this way, he could reduce his over-reliance on the ball while it was flying. He could use the corner of his eye to observe the opponent's position and the direction of the center of gravity movement, which would help improve his reaction speed. ** 2. Skill training ** 1. ** Pay attention to the connection of the ball ** - The connection between each ball was crucial. If his movement speed was slow, he could make up for it by increasing the speed of the ball's connection. In daily practice, you should pay attention to the continuity of hitting the ball and improve the speed of switching between different strokes. 2. ** Practice ball rubbing ** - Rubbing the ball was a skill that was easily overlooked but very important. Practicing rubbing the ball more often during normal times would allow him to grasp the initiative of the game and increase the probability of winning when playing against people of average level. It would also help to improve his overall skills. 3. ** Master the short pose technique ** - He could control the opponent's attack with a short stance, but it was difficult to master. If it was difficult for him to practice, he could find someone with a higher level or even a professional table tennis player to train him. After mastering the technique, it would be easier to deal with amateurs. 4. ** Strengthened serve technique ** - Serve was the key to improving table tennis skills. For those who wanted to improve their reaction speed, mastering the serve technique could control the rhythm of the game to a certain extent, creating more opportunities for themselves to take the initiative to hit the ball, thus improving their reaction speed. ** 3. Daily training ** 1. ** Focus training ** - He could use the table tennis trainer to train and play for about 20 minutes every day, which would help improve his concentration and reaction speed. 2. ** Strength training and footwork training ** - Carrying out moderate body strength training and footwork training could improve the reaction speed when playing, increase the flexibility of the body, and respond to the needs of large angle landing points. 3. ** Maintain a reasonable exercise frequency and intensity ** - Pay attention to the time, frequency, and intensity of exercise to avoid excessive exercise. Over-exercising might affect the body's condition and not be conducive to improving reaction speed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
A generation gap
The traditional view was that there was a small gap in three years, a big gap in five years, and a gap in ten years. At first, it meant that the generation gap between parents and children was about 20 years. Later, ten years became the boundary of the generation gap (such as the 70s, 80s, 90s, and 00s). With the rapid development of the times, the generation gap was shrinking. Now, when describing the age characteristics, it had been shortened to five years or even shorter. For example, there was an obvious generation gap between the post-95 and post-00 generation when there was only a difference of five years.

The Generation Gap Between the 60s and 90s
The post-60s and post-90s grew up in different eras, and there were differences in many aspects. The post-60s had experienced a period of relative material scarcity, and their lives might be more focused on the satisfaction of basic needs and hard work, while the post-90s mostly grew up in a relatively rich environment and were used to modern and convenient lifestyle. In terms of perception, for example, in terms of consumption concepts, the post-60s may be more inclined to frugality and practicality, while the post-90s may pay more attention to personality, quality, and experience. In terms of career planning, the post-60s may value stable and long-term career development, while the post-90s may pursue more diverse and flexible career choices and pay more attention to the realization of self-worth. However, the generation gap was not an insurmountable gap. On some common interests, such as the acceptance of smart cars, both sides may have the same choice. Moreover, if both parties were willing to understand and accept each other, they could also communicate and interact well across the generation gap.
