The concept of green infrastructure and ecological urban planning has become one of the leading directions in achieving sustainable development, environmental balance, and socio-economic well-being in the 21st century. As rapid urbanization continues across the globe, cities are facing severe environmental challenges such as air and water pollution, inefficient energy consumption, and climate-related risks. In this context, green infrastructure serves as a comprehensive approach to integrate natural systems into urban environments, providing ecological services such as clean air, green transportation, biodiversity protection, and climate adaptation. This article explores international practices in developing sustainable urban environments through green infrastructure, analyzing the experiences of countries such as Singapore, Denmark, Germany, and South Korea that have successfully implemented eco-friendly urban systems. Special attention is paid to the experience of Uzbekistan, where recent national policies have prioritized environmental modernization and ecological balance in urban planning.

In the modern globalized economy, strategic business management has become the central driver of corporate adaptability, sustainability, and competitive advantage. Through an analytical review of international practices and theoretical frameworks, this paper examines how business management—rooted in planning, leadership, innovation, and stakeholder integration—enables firms to thrive amid dynamic market conditions. Drawing upon Lominé, Muchena, and Pierce’s (2014) work on business management [1] and contemporary data from the OECD, World Bank, and McKinsey Global Institute, the analysis compares management structures and strategies across developed economies such as the United States, Germany, and Japan. The study demonstrates that organizations emphasizing knowledge-based management, digital transformation, and leadership development achieve superior growth performance and resilience, with an average productivity increase of 25–40% compared to less structured firms [2].

Crop is considered the most valuable, high – yield grain crop food, fodder, technical and agrotechnical importance. As food, cornstarch's Dogi is used. His Dogi is considered very nutritious and has an average content of 10,6% cutlet, 1,4% ash substances. But, in corn grain, the protein content is low. For this reason, bread is closed by adding 25-30% bug'doy flour to the corn flour. Since corn Dogi has a lot of precipitation (4,3-5,0%) in its composition, it quickly hurts it. Grain porridge is separated in special machines, flour is prepared from the rest, because in the composition of corn porridge contains about 25 – 40% fat, from which the oil used for food is prepared. In addition, cereals from corn cereals are prepared, during the milk – wax ripening period, it can be used as food, in which it is fried (tonsils) and boiled.

Currently, the health of people involved in high-performance and elite sports is of particular concern. Regular, intense physical activity causes changes in the human body, affecting most organs and systems, as well as fundamental biological processes. Research conducted in our country and abroad in recent decades shows that poor health and reduced athletic performance in athletes are associated with defects in nonspecific resistance and immune defense. Furthermore, the harmonious functioning of the immune system depends on the normal functioning of other organs and systems, so any disruption inevitably affects the athlete's immune status. Excessive training and competitive stress in athletes can lead to immunodeficiency and autoaggressive conditions. Long-term irritants that exceed the body's response thresholds lead to premorbid conditions, various disorders, and exhaustion. The period of increased susceptibility of the body to infections in elite athletes after acute and significant physical exertion is called the "open window." The "open window" theory links the surge in illness among athletes to short-term suppression of the immune system due to excessive physical exertion.

The human body's adaptation to intense physical activity is a key issue in muscle physiology and sports medicine. This issue's significance is further enhanced in the context of developmental physiology. The adaptation of young athletes to gradually and steadily increasing physical activity both facilitates the development of their motor potential and can overload immature systems, particularly the immune system. These and other factors determine the relevance of studying the adaptation of adolescents to intense physical activity—cross-country skiing.

Significant issues related to optimizing the structure, volume, intensity, and especially the dynamics of training loads for young skiers remain insufficiently studied. Analyzing the results of control competitions, functional fitness dynamics, and especially the results of major competitions for young skiers, a number of authors believe that traditional load planning does not contribute to achieving higher results in the main starts of the season. According to numerous literary sources, the traditional annual training cycle for young skiers has some shortcomings in the distribution of training loads throughout the annual sports training cycle. The main drawback, in our opinion, is that the bulk of the loads are essentially applied at the beginning of winter competitions, i.e., in November-December, and in a significantly smaller volume at the end of the season - February-March. V.S. Fomin emphasizes that not total " maximization " of loads in cyclic sports, but scientifically based " economization " can become a promising direction for finding solutions, especially in children's and youth sports

One of the trends in the development of the global sports movement at the end of the 20th century is the significant expansion of sports, individual disciplines, and competition programs in which women athletes participate, ranging from team and club competitions to the Olympic Games. Despite all their humanism, the first organizers of the modern Olympics did not dare to allow female athletes to participate. In 2010 alone, 11 athletes were admitted to the tennis and golf competitions at the Olympic Games in Paris, which constituted only 0.8% of the total number of participants. At the first Winter Olympics, 13 women (4.4%) took part. In subsequent years, the Olympic programs gradually expanded, and at the 2016 Games in Atlanta, women made up 35%, and at the Winter Games in Nagano, 44.2%. Almost any sport mastered by men has become feasible for women.
