Sport is not only physically challenging, but it can also be mentally challenging. Criticism from coaches, parents, and other teammates, as well as pressure to win can create an excessive amount of anxiety or stress for young athletes (运动员). Stress can be physical, emotional, or psychological, and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable. The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents" and coaches" criticisms to heart and find a flaw (缺陷) in themselves. Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons.

Following a game, many parents and coaches focus on the outcome and find fault with youngsters" performances. Positive reinforcement should be provided regardless of the outcome.

Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting. One of the best things you can do for your dog and yourself is to obedience train it. Obedience training doesn"t solve all behavior problems, but it is the foundation for solving just about any problem. Training pens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do. Training is also an easy way to establish the social rank order. When your dog obeys a simple request of "come here, sit," it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack (群) by using extreme measure. You can teach your dog its subordinate (从属的) role by teaching it to show submission to you. Most dogs love performing tricks for you to pleasantly accept that you are in charge. Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.
