Dynamics of morphological and functional indicators of 10–12-year-old football players involved in the children and youth sports school program

Abstract

Paper considers the dynamics of morphological and functional indicators of young football players 10-12 years old. Objective study was conducted among football players of the FC Arsenal. 24 football players of 10, 11 and 12 years old took part in it, who train according to the state program for children and youth sports schools of Ukraine. Results: Morphological indicators by age have an uneven tendency to change. Indicators of body weight, chest circumference and anaerobic anabolic (ANAME) and anaerobic metabolic capacity (AME) football players significantly increase every year (р>0,05). An analysis of heart rate data of football players showed that with age, indicators decrease. Arterial systolic pressure (BP syst.) and diastolic pressure (BP diast.) does not increase significantly with age. Conclusions: During the study, body length increased on average from 10 to 11 years (t = 2,10; p <0,05) and from 11 to 12 years (t = 2,01; p <0,05), body weight (t = 2,47; 2.96; p <0,05 - 0.01), chest circumference (from 11 to 12 years; t = 2,17; p <0,05), respectively. The indicators of the cardiovascular system significantly improved only in heart rate (from 10 to 11 years; t = 3.07; p <0.001), in BP, ANAME and AME no significant changes were identified. At the same time, indicators of the respiratory system significantly changed in VC (from 11 to 12 years; t = 2,20; p <0,05) and respiratory rate (from 10 to 11 years; t = 3.23; p <0.001). The obtained indicators indicate a moderate load of young football players who train according to the program of the children's and youth sports school, which is important during the formation of functions and systems of the children's body.
