The purpose of the study was to obtain regression models of immediate and delayed training effect of strength loads in boys aged 8 years, based on a full factorial experiment. Materials and methods. The study participants were 48 boys aged 8 years. The experiment was performed using a 22 factorial design. The study materials were processed by the IBM SPSS 22 statistical analysis program. The study examined the impact of four variants of strength load on the immediate (ITE) and the delayed (DTE) training effect of orthogonal strength exercises modes and rest intervals in boys aged 8 years. Results. The study results show that in the proposed matrix of the 22 full factorial design, the chosen step of variation of factors is sufficient to study the influence of different modes of strength exercises on the dynamics of ITE in boys aged 8 years. Based on the data analysis, the study obtained regression models of load for calculating the ITE1, ITE2, and DTE. The obtained regression models make it possible to calculate the number of repetitions and rest interval to achieve the most rational load variant. Conclusions. The analysis of regression equations shows the interrelation between training effects: ITE1 —> ITE2 —> DTE. The value of ITE1, ITE2, and DTE at station I (exercises to strengthen arms and shoulders) and station II (exercises to strengthen abdominal muscles) depends on the increase in the number of repetitions in a set and the duration of the rest interval. The value of ITE1, ITE2 at station ІІІ (exercises to strengthen back muscles) depends on the increase in the number of repetitions in a set and the duration of the rest interval. The value of DTE – on the increase in the number of repetitions in a set and the reduction of the rest interval duration. The value of ITE1 at station IV (exercises to strengthen leg muscles) depends on the increase in the number of repetitions in a set and the reduction of the rest interval duration. To strengthen the DTE, it is necessary to reduce the number of repetitions in a set and the duration of the rest interval.

“…It is well known that the level of coordination abilities development determines the success in developing motor skills (Khudolii, 2019;Marchenko & Dykhanova, 2019;Ivashchenko, 2020), but the results of testing coordination abilities showed that the girls and boys did not statistically significantly differ by these indicators (Table 1) and had a statistically significant difference in the level of proficiency in acrobatic exercises. For the girls, the proposed acrobatic exercises are difficult to perform.…”

“…To identify the patterns of motor function development, modern research uses methods of multivariate statistics such as factor and discriminant analysis (Brusseau & Burns, 2018;Hohmann, Siener, & He, 2018;Ivashchenko, 2020). Discriminant analysis allows to obtain both a regression equation to classify schoolchildren by their motor fitness level, and to Ivashchenko, O., Nosko, Yu., Bartik, P., & Makanin, O.…”

The purpose of the study was to identify gender-related peculiarities of 7-year-old schoolchildren’s motor fitness. Materials and methods. The study participants were 59 7-year-old schoolchildren (girls – 27, boys – 32). The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The study used the following research methods: analysis of scientific and methodological literature, pedagogical observations, testing of motor fitness, probabilistic approach to assessing the learning process, methods of mathematical statistics. The study recorded the primary schoolchildren’s level of proficiency in gymnastic exercises. The coefficient was determined by the formula: p = (m/n)×100, where p is the level of proficiency, m is the number of successfully performed exercises, n is the total number of attempts to perform the exercise. In the experiment, the study controlled the level of proficiency in the following exercises: forward roll; backward roll; shoulderstand with bent legs. Results. The differences in the development level of movement coordination of individual parts of the body and vestibular stability are not statistically significant; in the 7-year-old girls and boys, there is a statistically significant difference in the development level of strength, speed strength, speed, endurance, and the level of proficiency in acrobatic exercises. Conclusions. A canonical discriminant function can be used to classify and identify the indicators that have the greatest weight in assessing gender-related peculiarities of 7-year-old schoolchildren’s motor fitness. In assessing gender-related peculiarities of 7-year-old schoolchildren’s motor fitness, these indicators include the level of proficiency in acrobatic exercises, the level of relative strength of shoulder flexors, endurance, and speed strength.

“…Studies focus on the organization of pedagogical control in physical education classes (Ivashchenko, 2020;Koryahin, Blavt, & Ponomaryov, 2019), means and methods of influence (Chen, Dai, & Gao, 2017;Ivashchenko, Khudolii, Iermakov, Lochbaum, Cieslicka, Zukow, Nosko, & Yermakova, 2016;Skead & Rogers, 2016), and also on the use of pedagogical techniques of physical education with different nosologies in the educational process (Adyrkhaev, 2016;Bondar, 2000;Orikhovska, Andrieieva, Kashuba, Lazarieva, Lytvynenko, Kirichenko, Arefyiev, & Khrypko, 2020).…”

et al. 2020

The objective of the study was to determine the age-related peculiarities of functional and motor fitness of students of a special medical department of higher education institutions. Material and methods. The study participants were 1st year (n = 34); 2nd year (n = 14); 3rd year (n = 58); 4th year (n = 21); 5th year (n = 16) male students. One group was organized in each year of study, which added up to five experimental groups. All the students participated in physical education classes twice a week. To solve the tasks set, the following research methods were used: analysis of scientific literature, pedagogical observation, pedagogical testing, formative experiment, index method, biomedical methods, and methods of mathematical statistics. During classes, the study used the method of strictly regulated exercise (motor density of the class was 50-70%), for developing general endurance – the continuous method with covering a distance of 1,000-2,000 m (heart rate: 120-150 beats per minute), circuit and repetition methods. Results. The study results show positive changes in the functional state of the respiratory system and speed and strength abilities in the 1st-5th year students of the special medical department (p < 0.05). Conclusions. A successful development of the basic functional body systems and motor abilities in 1st-5th year students can be achieved under the influence of pedagogical conditions, namely: the method of strictly regulated exercise using exercise equipment (motor density of the class was 50-70%); the continuous method with covering a distance of 1,000-2,000 m at a slow pace (heart rate: 120-150 beats per minute); circuit and repetition methods. By the results of comparative analysis of the functional and motor fitness, the 1st-5th year male students of the special medical department show better results in tests for assessing the cardiovascular and respiratory systems, speed and strength abilities. In the 18-22 age range, according to the Ruffier index, there is an increase in the number of male students of the special medical department with a “good” and “satisfactory” cardiovascular system state and a decrease in the number of students with a “bad” result.
