Sports is always remain a heated topic for the discussion, some countries built specialised facilities to train top atheletes rather than providing sports facilities that everyone can use. In my opinion, it has both positive and negative impact for the development.
On the one hand, sports is very emotional topic for everyone, from young children to old citizen everyone play sports in different ways. They have their rights to get facilities which helps everyone. Providing special facilities for only top atheletes makes injustice for them. It will give negative impact for the country, the government gives special training to only top players then children will not able to learn new skills in game and it will affect to the country after some years. Every athelete is not born as rich, they also need support from his country so they can make their country proud. For example in 2024, olympics Pakistan won only few medals because they not providing facilities to the players. Pakistan athelete Arshad nadeem who won gold medal in Jawline in 2024 olympics he had no money to purchase good jawline people give money to him for jawline. it will gives negative impact for Pakistan.
On the other hand, Give special facilities to top athelete gives short term benefits to the country these players achieve medals in international sports until they retired. After that new generation will not able to catch old generation level in sports. Because every sports need lots of trining from childhood but government give special treatment to only top players.
At the end of the picture, every country has to focus on long term success not only on short term achievement.
