In some countries, they constructed specialized sport centre to provide professional training for the elite athletes use rather than opening for the public. In my opinion, I believe that is a positive development for country and necessary.
First, the main function of the specialized centre is proving a professional training environment, with hi-tech equipments for training and tracking the athletes’ health. Avoiding to open for publican can reduce facility utilization, which can decline the maintenance costs. For example, the national pitch only open when it has training and competition, also it was banned people access for protecting the grasses, which the ban decreased the damaging in grasses and the costs of maintenance.
Second, the cultivation of professional athletes needed to spend many years and extra investment by government, while they could positive for the national image and reputation when they became the best in the world. For instance, the number of wards in Olympic games which imply the power in the country, meanwhile, it also rise the national identity when their athletes achieve the prize. As the result, the specialized facilities only accounted for fewer numbers, whereas the government still constructed infrastructure for the public that enough for these using.
In conclusion, the essential factors of building the specialized facilities for national athletes were providing a professional circumstance and saving the unnecessary costs. At the same time, it could grow the national image and national identity if athletes have great achievement.
