The study purpose was to determine the dynamics of training effects of orthogonal modes of strength training in boys aged 8 years. 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 using the IBM SPSS 22 statistical analysis program.Discriminant analysis was performed. The study examined the impact of four variants of strength training loads on the immediate (ITE) and delayed (DTE) training effects of orthogonal modes of strength exercises and rest intervals in 8-year-old boys. Results. In the first variant of strength training, the largest contribution to the dynamics of training effects is made by the work performed at the first place “exercises to strengthen arm and shoulder muscles”; in the second variant, the largest contribution to the dynamics of training effects is made by the work performed at the third place “exercises to strengthen back muscles”; in the third variant, the largest contribution to the dynamics of training effects is made by the work performed at the first “exercises to strengthen arm and shoulder muscles” and the third “exercises to strengthen back muscles” places; in the fourth variant, the largest contribution to the dynamics of ITE is made by thework performed at the first “exercises to strengthen arm and shoulder muscles” and the third “exercises to strengthen back muscles” places. The most significant changes in the DTE are associated with the fourth place’s work “exercises to strengthen leg muscles”. Conclusions. The response to strength training load includes immediate and delayed training effects. Thus it can be argued that training effects can be classified using the given battery of tests based on discriminant analysis. The efficiency of discriminant analysis increases when using 2k FFE active experiments.

The purpose of this paper is to determine the impact of strength training modes on the dynamics of training effects in 8-year-old boys.  Materials and methods. The study participants were 48 boys aged 8. The experiment was performed using a 22 factorial design. The study implemented the first variant of the combined method for developing arm and shoulder muscles (station І), strength of abdominal muscles (station ІІ), strength of back muscles (station ІІІ), and strength of leg muscles (station IV). The study materials were processed using the IBM SPSS 22 statistical analysis program. Discriminant analysis was performed. The study examined the impact of four variants of strength load on the immediate training effect (ITE1) after performing exercises at four stations, the immediate training effect (ITE2) after training, and the delayed training effect (DTE) 24 hours after training.  Results. The findings indicate that each of the variants of strength load can be effectively used depending on educational objectives of both one or a series of physical education lessons, and also show that the ITE and DTE of strength training depend on the initial level of fitness and the total amount of strength training in a physical education lesson.  Conclusions. The findings point to the possibility of using a discriminant function to assess and predict the development of strength in 8-year-old boys. The study confirmed the effectiveness of using factorial designs to obtain objective data on the dynamics of training effects in primary school pupils.

Background and Study Aim. The purpose of the study was to determine the peculiarities of using pattern recognition method in the management of the cumulative effect of strength loads in 8-year-old boys. Materials and methods. The study participants were 48 boys aged 8. The experiment was conducted using a 22 factorial design. The study materials were processed by the IBM SPSS 22 statistical analysis program. Discriminant analysis was performed. The study examined the impact of four variants of strength load on the formation of the cumulative training effect of three, six, nine, and twelve classes in 8-year-old boys. Results. The discriminant analysis provided information about the impact of four orthogonal variants of strength loads on the formation of the cumulative training effect of strength exercises of three, six, nine, and twelve classes in 8-year-old boys. The obtained data make it possible to choose a load mode at each step of the CTE formation and to manage schoolchildren’s strength training. Conclusions. The verification of the obtained discriminant functions shows their high discriminative ability and value in interpretation with respect to the general population (p < 0.05). It was found that the formation of the CTE of three classes is most influenced by the third load variant, six classes – by the third load variant, nine classes – the third load variant, twelve classes – the first load variant. The discriminant function structure coefficients made it possible to identify the factor structure of the CTE of 3, 6, 9, 12 classes, to find that the CTE3, CTE6 are associated with the work at the first place “Exercises to strengthen arm muscles”, the CTE9, CTE12 – with the work at the third (“Exercises to strengthen back muscles”) and the fourth (“Exercises to strengthen leg muscles”) places. The CTE of three, six, nine, and twelve classes depends on the modes of strength exercises and has different focuses. The CTE3 – speed and strength focus; CTE6, 9 – comprehensive focus; CTE12 – explosive-strength focus. The obtained values of centroids for the CTE of 3, 6, 9, 12 classes enable the management of schoolchildren’s strength training.

The purpose of the study was to determine the impact of exercises modes on developing a small ball throwing skill in boys aged 8.  Materials and methods. The study participants were 21 boys aged 8, who were randomly divided into three groups of 7 people. The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. The study examined the influence of the number of repetitions on the effectiveness of teaching boys aged 8 throwing a small ball at a target. A pedagogical experiment examined the influence of 6, 12, and 18 repetitions with a 60-second rest interval on the increase in the level of proficiency in exercises of boys aged 8. In the first group, the boys repeated the task 6 times with a rest interval of 60 s, in the second group – 12 times with a rest interval of 60 s, in the third group 18 times with a rest interval of 60 s. When teaching throwing exercises during the class, the study evaluated the level of proficiency by the alternative method (“performed”, “failed”) and calculated the probability of exercise performance (p = n/m, where n is the number of successful attempts, m is the total number of attempts).  In teaching boys aged 8, the method of algorithmic instructions was used. The next exercise started after three successful attempts. Throwing a ball at a vertical target was taught. The study materials were processed by the IBM SPSS 20 statistical analysis software. During discriminant analysis, a prognostic model for group membership was created.  Results. Discriminant analysis made it possible to determine the impact of the number of repetitions on the effectiveness of developing the skills of throwing a small ball at a target; answer the question as to how significantly the modes of repetitions differ by the effectiveness of motor skills development, what class the object belongs to based on the values of discriminant variables. Conclusions. Based on the analysis of group centroids, it was found that in boys aged 8, six repetitions of the exercise (6 sets one time with a rest interval of 60 s) significantly influence the increase in the level of proficiency in exercises during physical education lessons. The results of group classification show that 85.7% of the original grouped observations were classified correctly.

The study objective is to determine the influence of the combined method of strength development on the dynamics of training effect in girls aged 9 years. Materials and methods. The study involved 15 girls aged 9. The experiment was conducted according to the plan shown in Table 1. The study implemented the first variant of the combined method for developing arm and shoulder muscles (place I), abdominal muscle strength (place II), back muscle strength (place III), and leg muscle strength (place IV). The study materials were processed by the statistical analysis software – IBM SPSS 22. Discriminant analysis was performed. Results. The discriminant analysis indicates statistically significant changes in the training effect of strength exercises (places І–ІV, р < 0.001). The immediate and delayed training effect of strength exercises depends on the total amount of strength exercises in a physical education lesson. Thus, changes after training at each place of strength development are amplified by the subsequent exercises at other places, the differences between the testing indicators are statistically significant (p = 0.001). Conclusion. The study determined a positive training effect of strength exercises when using the combined method of strength development in the following modes: dynamic effort method – 3 repetitions, 30-s rest; maximum effort method – 1 repetition, 30-s rest; isometric effort method – 3 repetitions, 30-s rest; repeated effort method – 6 repetitions, 30-s rest. In strength load response, there are an immediate and delayed training effects. Thus it can be argued that it is possible to classify training effects by the presented battery of tests based on discriminant analysis.

Strength training is an important part of the preparation of competitive athletes. The subject of interest of the scientists connected of sports swimming was the level of strength ability of the competitors practising this sport and the influence of this ability on the final sports result. The purpose of this review is to describe and consider the impact of strength training of the shoulder muscles in sports swimming. A literature review was conducted in Embase, Medline PubMed, DOAJ, EBSCO and Google databases. Basic search terms are: training in sports swimming, strength tests, evaluation of muscle properties, rotation of the arm, strength measurement methods. Results: 235 results were found and 148 professional publications were selected and analysed. A thorough review of scientific publications indicates that strength parameters of the shoulder girdle muscles played a very important role on the sports performance of swimmers. The programmes combining swim training with 'on land' strength improvement or electrical stimulation are more effective than swim training alone. Significant fatigue of the rotator muscles can impair shoulder stability and result in injury. Increased strength in the internal rotation movement may result pathological conditions of the shoulder.
