Individual Factorial Structure of Biomechanical and Psychophysiological Indicators as a Basis for Determining the Fighting Style of Qualified Veteran Boxers

Abstract

Purpose: to reveal the fighting style of veteran boxers based on the individual factor structure of psychophysiological and biomechanical indicators.
 Material and methods. The study involved 42 qualified veteran boxers (aged 45-50). A biomechanical analysis of the indicators of the movement speed of various points and the values ​​of the joint angles while performing a direct blow by boxers has been used as a research method. The psychophysiological method has been used to determine the time of a simple and complex reaction under standard conditions and in various testing modes. Descriptive Statistics and Factor Analysis have been applied as methods of statistical analysis.
 Results. Two main factors have been identified in the structure of the complex performance of qualified veteran boxers,. Factor 1 (55.063% of the total aggregate variance) is named "Speed". Factor 2 (44.937% of the total aggregate variance) stands for “Speed ​​Endurance”. Individual factor structure, which is characterized by the distinctive factor "Speed ​​and Coordination Endurance" by more than 80% as well as by the marked factor "Speed" by less than 30% is considered to be a particularity of the tempo style boxers. Individual factor structure, which is characterized by the intensity of the factor "Speed" by more than 80%, and by the distinctive factor "Speed ​​and Coordination Endurance" by less than 30% is considered to be typical for the playing style boxers. The individual factor structure, which is characterized by the marked factor "Speed" by more than 50%, and by the intencity of the factor "Speed ​​and Coordination Endurance" by less than 30% is seen to be peculiar to the strength style boxers.
 Conclusions. It is shown that the psychophysiological features of boxers of different fighting styles are reflected in the features of the direct strike technique. The lack of speed at the beginning of the movement in tempo style boxers is supplemented and compensated by the high speed of movement. Playing style boxers are characterized by a high speed of movement at the very beginning of the strike. Strength style boxers are characterized by the gradual development of movement speed.

Biomechanics of martial arts: the analysis of the scientific resources of Scopus

“…Definitely gone are the days of merely intuitive training, based solely on movement patterns inherited from masters and reproduced for decades [21,22]. Nowadays, an increasing number of scientists are engaged in conducting biomechanical research to identify the factors that influence the performance of strokes [23,24].…”

Special physical fitness factors of athletes involved in pole sports

“…Modern scientists (Kozina, Kozin, Cieślicka, Prusik, Muszkieta, Sobko, Ryepko, Bazilyuk, Polishchuk, Osiptsov, Kostiukevych, 2017;2020 [14,15,16,24,25] actively use multidimensional analysis methods for study of the structure of integral preparedness of young and qualified athletes in various sports. Leading Ukrainian specialists Kozina, Kozin, Boychuk, Skaliy, Zelenskiy, Honcharenko (2019, 2021) consider the most suitable mathematical tool -factor analysis, which allows you to reduce a wide range of readiness indicators and identify the main components that determine the exact characteristics of individual characteristics of athletes [14,15]. The use of modern methods of Health, sport, rehabilitation Здоров'я, спорт, реабілітація Здоровье, спорт, реабилитация 8(4) analysis helps to create optimal training techniques that most meet the requirements of the training process in a specific period of time.…”

“…In sports games, with the help of factor analysis, scientists Kozina, Khrapov, Yevstratov, Kolomiets, Hryshchenko, Minenok, Nosko, (2019) develop individual factor models of physical fitness of athletes of different game role [15]. In martial arts, on the basis of the individual factorial structure of psychophysiological and biomechanical indicators, scientists identify the fighting style of veteran boxers [14]. In this regard, the researches in this work confirm and supplement the data of the above authors, regarding the need for a factor analysis of physical development indicators, special physical and functional preparedness to determine the peculiarities of training athletes with Pole Sport.…”

“…Based on the results of assessing the level of physical and functional training, it can be argued that the level of training of athletes involved in pylon sports is sufficient [5]. As is know [14,15,16,17], factor analysis is used to reduce variables and determine hidden relationships between indicators and identify the main components that determine the structure of athletes' preparedness. In this study, factor analysis made it possible to identify six factors (table 4).…”
