Anthropometric and motor changes of girls after a year of aerobic gymnastics training
The purpose of this research was to study the effect of specific aerobic gymnastics classes for one year on individual anthropometric and motor parameters of girls aged 6-11 years. The study involved 23 girls (the average age at the beginning of the study was 8.04±1.22 years) representing 2 different aerobic gymnastics sports clubs in the city of Astrakhan. The selected group has completed its regular training and competitions for a period of one year. The measurements were carried out in January 2021 and January 2022, in the middle of the preparatory period. The normality of the distribution of features was checked using the Shapiro-Wilk criterion. The data were analyzed using the Wilcoxon sign rank criterion. Taking into account anthropometric indicators, significant changes (p<0.01) in height, body weight and BMI were noted. Taking into account the engine parameters, the average values of the endurance test in holding apart and extending the back significantly increased to the level of p<0.05. The average values of the 4x10 m shuttle run, the long jump from a standing position, modified push-ups, squats in 60 seconds significantly increased to the level p< 0.01. No significant changes were observed in the hanging test on bent arms or knee flexion in the hanging test. On the other hand, the indicators of a 1-leg stand with closed eyes and a 2-minute endurance shuttle run decreased slightly.
