As seasons change, we can say with some exaggeration that the preparation periods also change. The period of summer preparation, known as summer pre-season (SPS), has its own specifics and differences compared to the winter preparation period. First and foremost, it is important to emphasize that in our climatic conditions, the biggest difference lies in the current weather conditions and temperature variations between winter and summer. The second most significant difference, which gradually diminishes, especially in professional football, is the length of the preparation period. The summer preparation period in football is generally shorter compared to the winter period.
