“…On the basis of the analysis of communities it is determined that the most informative in girls aged 12-14 years are the following tests: which characterize the development of dynamic and static strength of muscles of the legs and hands (girls 12 years old); which characterize the development of static, high-speed strength of leg muscles, static and dynamic strength of the muscles of the abdomen and hands (girls 13 years old); which characterize the development of the static and dynamic strength of leg muscles, the dynamic strength of the muscle of the hands (girls 14 years old). These results supplement the data of other authors [22,25] on pedagogical control in the physical education of schoolchildren.…”

“…The obtained results characterize the peculiarities of the dynamics of force readiness of middle classes girls and complement the data of Veremeenko [24], Ivashchenko et al [25] on the regularities of motor preparedness of children and adolescents. The authors recognize that with age, the weight of high-speed force and coordination of movements in the structure of motor-preparedness of girls increases.…”

To determine the structure of the development of power abilities in girls aged 12-14 years Material: Girls aged 12 years (n = 20) participated in the study; 13 years (n = 27), 14 years old (n = 30). Factorial analysis performed. Results: It is determined that the most informative in girls of 12-14 years old are the following tests: which characterize the development of dynamic and static strength of muscles of the feet and hands (girls of 12 years old); which characterize the development of static, high-speed strength of leg muscles, static and dynamic strength of the muscles of the abdomen and hands (girls of 13 years old); which characterize the development of the static and dynamic strength of leg muscles, the dynamic strength of the muscle of the hands (girls of 14 years old). Conclusions: Factor analysis allowed to determine informative indicators for controlling the development of power abilities in girls of 12-14 years old. The greatest weight in power preparedness has the relative and static strength of the leg muscles. In the second place, girls of 12-13 years old have the development of muscle strength shoulder girdle. 14 years old girls in second place, have the development of dynamic and static strength of the abdominal muscles and the dynamic strength of muscles of the shoulder girdle. Girls of 12 years old in third place have the development of coordination of movements, the static strength of the shoulder girdle and the dynamic strength of the back muscles. Girls of 13 years in the third place have development of the development of muscle strength of the abdomen. Girls of 14 years in third place have development of highspeed force and coordination of movements.

“…In sports training, the DA and PCA is a reliable analytical tool for categorizing subjects using a set of sEMG parameters. The productivity of a training program could also be estimated by the changes in parameters of interest in a subject (Czaplicki, Śliwa, Szyszka, & Sadowski, 2017;Ivashchenko, Khudolii, Iermakov, Prykhodko, & Cieslicka, 2018 (Vila-Chã, Falla, & Farina, 2010). Furthermore increase sample size, items/parameters could provide a significantly accurate and reliable multivariate fatigue model.…”

The aims of the study were: 1. To analyse the discriminative power of neuromuscular components for classifying the pre and post muscle fatigued states. 2. To examine whether the modification of neural recruitment strategies become more/less heterogeneous due to fatigue. 3. To research the effect of Erector Spinae (ES) muscle activity collectively with Rectus Abdominis (RA) and External Oblique (EO) muscle activity to identify the reduced spine stability during fatiguing Plank. Material and methods. Twelve boys (age – 12-14 years, height 148.75 ± 10 cm, body mass 38.9 ± 7.9 kg) participated in the study. Multivariate Discriminant Analysis (DA) and Principal Component Analysis (PCA) were applied to identify the changes in the pattern of the electromyographic signals during muscle fatigue. In DA the Wilks’ lambda, p-value, canonical correlation, classification percentage and structure matrix were used. To evaluate the component validity the standard limit for Kaiser-Meyer-Olkin (KMO) was set at ≥0.529 and the p-value of Bartlett’s test was ≤0.001. The eigenvalues ≥1 were used to determine the number of Principal Components (PCs). The satisfactory percentage of non-redundant residuals were set at ≤50% with standard value >0.05. The absolute value of average communality (x̄ h2) and component loadings were set at ≥0.6, ≥0.4 respectively. Results. Standardized canonical discriminant analysis showed that pre and post fatigued conditions were significantly different (p = 0.000, Wilks’ lambda = 0.297, χ2 = 24.914, df=3). The structure matrix showed that the parameter that correlated highly with the discriminant function was ES ARV (0.514). The results showed that the classification accuracy was 95.8% between fatigued conditions. In PCA the KMO values were reduced [0.547Pre fatigue vs. 0.264Post fatigue]; the value of Bartlett’s sphericity test was in pre χ2 = 90.72 (p = 0.000) and post fatigue χ2 = 85.32 (p = 0.000); The Promax criterion with Kaiser Normalization was applied because the component rotation was non-orthogonal [Component Correlation Matrix (rCCM) = 0.520 Pre fatigue >0.3Absolute<0.357Post fatigue]. In pre fatigue two PCs (cumulative s2 – 80.159%) and post fatigue three PCs (cumulative s2 – 83.845%) had eigenvalues ≥1. The x̄ h2 increased [0.802 Pre fatigue vs. 0.838 Post fatigue] and the percentage of nonredundant residuals reduced [50% Pre fatigue vs. 44% Post fatigue] from pre to post fatigue. Conclusions. The variability and heterogeneity increase in the myoelectric signals due to fatigue. The co-activity of antagonist ES muscle is significantly sensitive to identify the deteriorating spine stability during the fatiguing Plank. Highly correlated motor unit recruitment strategies between ES and RA, providing supportive evidence to the concept of shared agonist-antagonist motoneuron pool or “Common Drive” phenomenon during fatigue.

“…Bondarevsky's method" and test 14 "Shuttle run (4х9 m)", which characterize vestibular stability and general movement coordination . Unlike boys, to identify the level of coordination abilities development in girls aged 11, 12 and 13, it is advisable to use the tests that characterize relative and speed strength, the sense of running speed and vestibular stability (Ivashchenko, Khudolii, Iermakov, Prykhodko, & Cieslicka, 2018).…”

The study objective is to determine the possibility of identifying the state of coordination abilities development in girls and boys aged 11-13 using the methodology of multidimensional statistics. Materials and methods: Study participants. The study involved girls: 11 (n=20), 12 (n=23), 13 (n=19) years old; boys: 11 (n=21), 12 (n=20), 13 (n=19) years old. Study organization. The paper used analysis and generalization of scientific literature data, testing, discriminant analysis. Testing procedure. The testing program included well-known tests (Liakh, 2000; Serhiienko, 2001; Ivashchenko, 2016). Study results: The first canonical function explains 65.7% of the results variation, the second one – 25.1%, the third – 4.8%, which indicates their informative value. The coefficients of canonical correlation indicate the prognostic value of these functions. The first canonical discriminant function is most substantially related to the results of tests 4 (r=0.526), 14 (r=0.377), 2 (r=-0.306): therefore, a significant difference between the girls and boys aged 11-13 is observed in the development level of relative and speed strength, movement coordination. The structure coefficients of the second canonical discriminant function indicate that the function is most substantially related to variables 2 (r=0.502), 16 (r=0.434), 9 (r=0.379), 17 (r=0.357): so, a significant difference between the girls aged 12-13 and boys aged 11-13 is observed in speed strength, vestibular stability, and anthropometric data. Conclusions: The discriminant models characterize both age- and gender-related peculiarities of movement coordination development in the girls and boys aged 11-13. The data obtained show significant differences between the groups of girls and boys aged 11-13 both in the structure of coordination abilities development and the level of preparedness, and highlight the need to conduct separate physical education classes for girls and boys. Different programs should be used to develop coordination abilities in boys and girls aged 11-13.
