In the case of baseball, for example, the Youth Olympic Baseball Games has an age limit of 14 to 18 for the following reasons:

1. Focus on Youth Development:The Youth Olympic Games aim to bring together talented young athletes from around the world. This age group is a critical stage in the development of young people, and by setting an age limit, you can ensure that the competition focuses on this specific group of athletes, providing them with a global stage to showcase their talents and skills.

2. Nurturing future sports talent:The Youth Olympic Games is not only a platform for competition, but also focuses on the education and growth of athletes. By participating in the Youth Olympic Games, young athletes are exposed to a higher level of training and competition environment, helping to develop their athleticism, teamwork and Olympic spirit. Age restrictions help ensure that participants are at an appropriate age for this type of development and exercise.

3. Keep the game fair and competitive:Athletes of different ages differ in terms of physical development, skill level, and competitive experience. By setting an age limit, you can ensure that the contestants compete under relatively equal conditions, so as to maintain the fairness and competitiveness of the competition.

4. Comply with IOC regulations:The Youth Olympic Games (YOG) is a global sporting event hosted by the International Olympic Committee. The International Olympic Committee (IOC) has set an age limit for athletes when formulating the rules for the Youth Olympic Games, taking into account the developmental characteristics of young people and the fairness of sports events. Complying with this rule helps to preserve the reputation and authority of the Youth Olympic Games.
