Football Players’ "Cardiorespiratory System and Intermittent Endurance" Test

Abstract

Twenty six football players of the Shandong Luneng youth team (U17), the 2019 season Chinese National Youth Super League champions. Based on a comprehensive assessment of the working capacity and func- tional support of intermittent endurance, the levels and changes in the reaction of the cardiorespiratory system and energy supply of football players’ activities were analyzed under the condition of fatigue cu- mulating in the process of performing a series of high-speed segments. The prerequisite for testing was the preservation of the parameters of running 70 m in 10 s during the entire testing period. Content of Cardiorespiratory System and Intermittent Endurance test: duration of work in a series – 4 minutes; dura- tion of work with the maximum available intensity – 10 s (running distance 70 m), rest interval – 20 s. The number of combinations of work segments 10 s and rest intervals 20 s in a series is 8. The efficiency of work is assessed by the number of completed series and the reaction of the cardiorespiratory system. The typo- logical differences in the functional support of the special working capacity of football players who had a high level of working capacity were determined. They are associated with a balanced type of aerobic and anaerobic energy supply, with an insignificant tension of the mechanisms for fatigue compensating and a predominantly anaerobic type of energy supply provided a high level of respiratory compensation for met- abolic acidosis.

Characteristics of Functional Support for Specialized Physical Performance in Rowers

“…В спеціальній літературі представлено певний спектр факторів, які формують структуру функціонального забезпечення спеціальної працездатності спортсменів [2]. Представлені якісні та кількісні характеристики швидкої кінетики фізіологічних процесів [3], стійкого стану та сталого розвитку реакцій [4,5], спроможності компенсації втоми в умовах високої інтенсивності фізичних навантажень [6,7]. Всі ці компоненти ґрунтуються на високоспеціалізованих реактивних властивостях організму, які визначають спроможність швидко, адекватно і в повній мірі витримувати фізичні навантаження.…”

“…Even in low doses, cadmium has a toxic effect on the nervous system, immune system, reproductive system, and cardiovascular system [2,3]. Since cadmium is actively involved in physiological processes [4] and can cross the placental barrier, its accumulation leads to changes in the activity of various enzymes, shifts in the main morphological parameters, and significantly disrupts the balance of trace elements in the adult rat and embryos [5]. Cadmium can both increase the content of certain trace elements, causing their retention in tissues and organs and vice versa -cause significant losses of certain divalent cations, replacing them with itself.…”

“…The particular literature presents a certain range of factors that form the structure of functional support of special performance of sportsmen [2]. The qualitative and quantitative characteristics of the fast kinetics of physiological processes [3], steady state and sustainable development of reactions [4,5], and the ability to compensate for fatigue under conditions of high-intensity physical activity [6,7] are presented. All of these components are based on highly specialised reactive properties of the organism that determine the ability to quickly, adequately and fully withstand physical activity.…”

“…Однією з них є система тестування, представлена у футболі, боксі, видах веслування під умовною назвою «Cardiorespiratory System and Intermittent Endurance. Test» [12]. Ця система дозволяє вивести на максимальний рівень функціонування реакцію КРС і енергозабезпечення роботи, оцінити функції в умовах виражених повторних та змінних режимів діяльності.…”
