The purpose and motivation for choosing a table tennis event

1. If you are a young person and rely on this sport to eat table tennis for a lifetime, the purpose is to be a national and even world champion; Motivation is to strengthen one's health, make friends, improve one's own (family, family's) living conditions, and win glory for the country.

2. If it is purely for physical fitness, this is one of the best sports in my opinion, one is that there is no physical contact and it is not easy to get injured; The second is that almost all the limbs of the body, such as the brain, eyes, hands, and legs, are involved in each return in the sport.

In addition, just for the sake of physical fitness, I recommend another item, that is, swimming, which is beneficial to almost all the bones, nerves, and internal organs of the whole body.

Guided by the decision theory and motivation theory, and using the research paradigm of experimental psychology, this paper studies the conflict of return motivation of juvenile table tennis players through the investigation of the framework effect of the return motive conflict and the three groups of mixed experiments close to the actual combat. The results show that when using positive language to express the receiving situation, the players show a risk aversion preference. When using negative language to describe the return situation, the player shows a risk-seeking preference, resulting in a return framing effect.

At the same time, there are individual differences in the framing effect. Secondly, the conflict of avoidance motives affects the initiative and aggression of the serve, and when the game is leading, the avoidance of the return motive is conducive to improving the initiative and aggression of the serve. When the score is behind, the return motivation that tends to be greater than the avoidance is conducive to improving the aggression of the return and so on. Thus, it provides a theoretical basis for the decision-making of coaches and athletes in the situation of conflict of return motives.

Purpose: To strengthen the body Motivation: Hobby.

What's right for you is good. It is necessary to consider your own playing style to choose the softness, hardness and elasticity of the bottom plate; The stickiness, thickness, hardness and elasticity of the rubber sheet.

It's elastic and easy to hold, but you still have to get used to your racket to make it a good table tennis racket.

Generally, brands can also buy a 200 or so one, it's about the same, the racket is thicker, elastic and smooth.

Choosing table tennis: When purchasing, you should master the following four essentials:

Appearance: The surface of the ball must be fine and non-reflective, and the waist seam of the ball must be neat and crisp.

Bounce Height: The ** height of throwing the ball from a height of 305mm onto a standard table tennis table is between 235mm and 255mm. If the bounce of the ball is high or low, it means that the elasticity of the ball is uneven.

Roundness: Place the ping pong ball on a smooth, flat surface and rotate to see if there is any vigor**. It means that the roundness of the ball is not good, the stability of the ball is poor, and the landing point of the ball is not easy to control.

Hardness: Pinch the pre-part of the ball with your thumb and index finger to observe whether the softness and hardness on both sides are consistent. If the degree of ** is the same, it means that the hardness quality of the ball is better, and the performance is better.

You need to know the role of investment banks – financial intermediation.

Why should there be financial intermediaries?

First, private capital investment belongs to the investor, who has capital in hand but does not have projects, or does not have many alternative projects.

Second, the enterprise or the party in short supply of funds, that is, the investee, has investment projects, but there are no investors.

Third, this has created information asymmetry, and those who want to invest money cannot find the investors who are short of money, so financial intermediaries came into being.

The advantages are obvious, the investment bank has large customers in hand, has a lot of information about the investor, and is not bad for funds**. At the same time, the investment bank also has investors in urgent need of funds, which can play an intermediary role and balance the information asymmetry between the two sides.

At the same time, investment banks have high reputation and professional financial service talents, which can reduce the moral hazard of investors and investees to a certain extent. There is no such thing as a fake project.

Therefore, it can be said that private capital investment and investment banks mainly look at the investment banks with good investment project information in their hands, and the investment banks are unwilling to smash their own signboards, and will definitely investigate investment projects, which are relatively low-risk.

Of course, there is also moral hazard in investment banks, such as whitewashing projects for the sake of selling them, so everything has to look at both sides.

That's it, I hope to answer your doubts.

It is enough to remember one point, no matter what you invest, it means that this thing is profitable, it is just a matter of the size of the interests, the banks are absolutely profitable under the market economy, and China is gradually opening up private banks, in fact, the richest is not the state, but the people. Got it? If you have any questions, you can continue to ask.

At present, this aspect has not been completely opened, and the purpose can only be said to be unified management and risk prevention. Specific goals and motivations, you have to go.
