Relationships between the heart rate of badminton players 10-12 years in a competitive activity

Abstract

An integral indicator that helps to regulate the parameters of external load for badminton athletes is the heart rate. Considering the requirements for physical preparation and significant interdependence with the functionality of young athletes, we consider it appropriate and informative to determine this indicator in the dynamics of competitive activities and to establish the relationship of these data. Purpose: to establish the relationship between heart rate indicators within the competitive activities of Ukrainian badminton players d 10-12 years at the stage of preliminary basic preparation. Methods: theoretical analysis and generalization of scientific and methodological data to clarify the problem field of research, pedagogical observations of heart rate indicators during the competitive activities of Ukrainian badminton players 10-12 years, methods of mathematical statistics for processing the data. During 2019, competitive activities were analyzed with the participation of 67 badminton players 10-12 years in competitions of the national level. Results. The essence of the impact of physical activity on the organism of badminton players 10-12 years was determined by zones. The first zone provided for the indicators to be in the range of 124 beats/min., the second – 125−145 beats/min., the third – 146−166 beats/min., the fourth –167−187 beats/min. and the fifth – more than 188 beats/min. After analyzing the data, the correlation coefficient between 16 groups of data was determined. It was reflected certain characteristics of the heart rate in the conditions of competitive activity. Conclusions. The correlations of heart rate indicators within the competitive activity of Ukrainian badminton players 10-12 years at the stage of preliminary basic preparation was established. These correlations indicated that with increasing stay of athletes in the fifth zone of heart rate decreases duration and share of stay in the first-third zones of heart rate. At the same time the indicators of average and maximum heart rate of athletes in the conditions of competitive activity increase. In all load zones (according to heart rate) there is a high level of density between the indicator of absolute duration and the relative share of stay in the corresponding load zone (r = 0.89−0.92).
