The article is devoted to the study of effective methods and strategies for improving strength abilities in qualified football players. Given the constant development of modern football and its demanding physical training of players, a wide range of reasons associated with the increase in strength performance in football players is investigated. The article discusses training techniques and methods aimed at increasing muscle strength, endurance and elasticity in football players. The authors analyze the impact of various physical exercises, including heavy strength training, functional training work, and exercises to develop stability and speed. The second part of the paper is devoted to the consideration of a differentiated approach in the training of football players, which is an important element in improving the physical and technical skills of players at different stages of their careers. It is established that a differentiated approach involves individualization of the training process, taking into account the characteristics of each player and his level of training.The ways of applying a differentiated approach in the formation of physical, technical and tactical competence of football players at different stages of their development are identified.The methods and strategies that allow coaches to effectively adapt training programs to the needs and capabilities of each player, ensuring the optimal development of their sports potential, are analyzed. Particular attention is paid to the individual characteristics of players, such as physical aptitude, technical skills, intellectual abilities and psychological stability, and how these characteristics can be taken into account when developing training programs. In conclusion, the article highlights the key aspects of improving strength abilities in skilled football players and provides recommendations on training methods to achieve optimal results on the field.

Aim: The article is dedicated to the study of the efficiency of complex of physical exercises on the dynamics of work of the cardiovascular system in primary school-age children with. Evaluation of the efficiency of influence of the complex of physical exercises on the dynamics of work of the cardiovascular system of children with scoliosis. Materials and Methods: 30 children (18 boys and 12 girls) with scoliosis, who performed the complex program of physical exercises, were examined. The age range of children is from 7 to 10. The activity of the cardiovascular system was evaluated based on the parameters of pulse pressure, stroke volume, maximal and relative aerobic capacity, pulse tolerance limit, and mean aortic pressure. Results: A possible increase in all parameters of the cardiovascular system after physical exercises was found. Increase in Maximum aerobic capacity (200,01±11,27 against 94,11±6,79 in boys; 210,01±7,90 against 64,32±1,22 in girls; (р<0,05) and relative Maximum aerobic capacity (5,97±0,51 against 3,57±0,79 in boys; 6,81±0,67 against 2,62±0,19 in girls; р<0,05) was shown. A possible increase in aortic pressure after physical exercises can indicate the increased pressure on a child’s organism. Conclusion: Scoliosis progression in children forms increased pressure on the work of the cardiovascular system, which manifests in the increase of pulse, mean aortic pressure, and stroke volume, and differs depending on age and sex and requires the development of the individual rehabilitation plan with consideration of found changes.
