The study objective is to determine physical exercises modes when developing motor skills in girls aged 14. Materials and methods. The participants in the study were 40 girls aged 14. To achieve the objective set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of training tasks; pedagogical experiment, methods of mathematical statistics, methods of mathematical experiment planning, discriminant analysis. Results. The first canonical function explains 73.3% of the variation in results, the second function – 21.6%, which indicates their high informativity (r1=0.898; r2=0.743). The analysis of canonical functions highlights the statistical significance of the first and second canonical functions (λ1=.067; р1=0.001; λ2=0.346; р2=0.001). The first and second functions have a high discriminative ability and value of interpretation with respect to the general totality. The number of repetitions for mastering the first and fourth series of training tasks has the largest contribution to the first canonical function. This indicates that the exercises for developing motor abilities and teaching to control movement time and muscular effort influence the effectiveness of teaching a press headstand and handstand. The number of repetitions for mastering the second and third series of training tasks has the largest contribution to the second canonical function. This indicates that starting and ending positions, and actions without which the exercise performance is impossible influence the effectiveness of teaching a press headstand and handstand. Conclusions. The discriminant function structure coefficients show that the training program effectiveness is determined by selecting the series of training tasks and their performance modes. To choose the most rational mode of exercises of the series of tasks when teaching girls aged 14 a press headstand and handstand, the first discriminant function can be used with an emphasis on the most informative variables.

The study objective is to determine physical exercises modes when developing motor skills in girls aged 15.Materials and methods. The participants in the study were 40 girls aged 15. To achieve the objectives set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of training tasks; pedagogical experiment, methods of mathematical statistics, methods of mathematical experiment planning, discriminant analysis. To achieve the objective set, the study examined the effect of different variants of performing exercises, specifically: the number of repetitions (x1) and rest intervals (x2) on mastering a press headstand technique. The girls aged 15 were divided into four groups according to the experiment plan. During the learning process, a method of algorithmic orders was used. The student could proceed to the next exercise only after a correct performance of the previous exercise on three consecutive attempts. The number of repetitions needed to teach exercises in each series of training tasks was recorded. The level of proficiency in the physical exercises performance was determined by the alternative method: “performed” or “failed”. A technically correct performance of the exercise gave the students “1” point; a failure to perform the exercise gave them “0” entered in the protocol.Results. The 22 type experiment made it possible to study the multifactorial structure of teaching the girls aged 15, using a program of algorithmic orders; to specify optimal correlations of factors for their use when teaching physical exercises during physical education classes; to collect data for the calculation of regression models of teaching separate series of training tasks and for discriminant analysis to obtain a generalized model of teaching an exercise in general.Conclusions. To select a generalized mode of exercises of the series of tasks when teaching girls aged 15 a press headstand and handstand, the first discriminant function can be used with an emphasis on the most informative variables.The regression equations obtained from the analysis of the 22 full factorial experiment data make it possible to specify and select the most effective modes of exercises for mastering separate series of training tasks.

Research objective. To improve the methods of pedagogical control of motor and functional preparedness of female high schoolers. Materials and methods. To achieve the tasks set, the research used the following methods: analysis of scientific and methodological literature, pedagogical testing and methods of mathematical statistics of data reduction. Statistical analysis. We used the IBM SPSS 20 program of statistical analysis to process the research materials. It calculated the following statistics for each variable: mean, standard deviations, Student's t-test criteria for independent samples. During the discriminant analysis, we created a prognostic model for belonging to a group. This model builds the discriminant function (or a set of discriminant functions in case of more than two groups) as a linear combination of predictor variables, which ensures the best division of groups. The participants in the study were 22 girls aged 15, and 32 girls aged 16. Research results. The canonical function obtained explains 100% of the variation of the results, and is informative for the classification of motor and functional preparedness of the girls aged 15-16. The analysis of the canonical function proves its statistical significance (λ=.489; р < .0001). The structural coefficients of the canonical discriminant function show that the levels of functional preparedness of the girls aged 15 and 16 considerably differ. Conclusions. The girls aged 15 show better motor and functional preparedness than the girls aged 16. This indicates that the reason why the 16 year-old girls fall behind the 15 year-old girls is the decrease in physical activity at the age of 16. The levels of the functional preparedness of the girls aged 15 and those aged 16 differ significantly. The data obtained show a prognostic significance of the discriminant function in assessing the level of motor and functional preparedness of the girls aged 15-16. The discriminant model can be used for pedagogical control of the level of motor and functional preparedness of girls aged 15-16.

The objective is to determine the influence of the physical exercises modes on effectiveness of motor skills development in 5th-7th grade girls. Materials and methods. The study involved 5th grade girls (n = 28), 6th grade girls (n = 28) and 7th grade girls (n = 24). To solve the tasks set, the study relied on general scientific and special research methods, methods of mathematical experiment-planning.Studying the influence of different variants of the educational process structure, namely: the number of repetitions (x1) and the rest intervals (x2) on acquisition of the technique of physical exercises performance, provided for achieving the objective. A full 22 type factorial experiment was conducted. The 5th-7th graders were divided into training groups according to the experiment plan. In total, there were twelve experimental groups organized, four in each class.Results. The analysis of the regression equations shows that the rest interval between repetitions (x2) has the greatest influence on teaching 5th-7th grade girls physical exercises, with the number of repetitions (x1) being of somewhat less significant influence. The relation between these factors (x1x2) has a considerable weight in teaching to “rope climb in two or three sets” and to do a “pullover mount with a swing of one and a push-off with the other leg”.Conclusions. To increase the effectiveness of teaching 5th-7th grade girls physical exercises, the number of repetitions in throwing exercises should be increased to twelve times, and the rest interval reduced to 60 seconds. In the 7th grade, the number of repetitions should be reduced to six times, and the rest interval – to 60 seconds. The rest intervals in the exercises: “pullover mount with a swing of one and a push-off with the other leg” and “rope climbing in two or three sets”, should be reduced to 60 seconds and the number of repetitions – to six.

The Impact

The aim of the present study was to identify the relationship between morphological parameters and motor skills that are important for sprint performance in children aged 8 to 16 years divided into four age groups (U10, U12, U14, U16) in both genders. The sample consisted of two hundred eighty one participant who trained sprinting in various athletic clubs. A prediction set of twenty-five variables for assessing morphological characteristics and motor skills was applied, and the criterion variable was a sprint at 60m. Using multiple correlation, it has been established that a large number of morphological characteristics are statistically significant positive correlation with the sprint, especially the longitudinal variables, while the variables of skinfolds showed a low negative statistical significance in relation to the given criterion. In the field of motor skills, the highest number of positive statistically significant correlations were found in the tests of explosive power of the upper and lower extremities, agility test and horizontal and vertical jump tests. In order to determine which morphological features and motor skills should be applied in sprint running training, we tested related attributes using different algorithms for data mining (LR, M5, KNN, SVM, MLP, RBF). The results suggests that the predictors that we use can continue to be applied with high reliability in assessing sprint performance, but also in the monitoring of the training process in order to profile the better sprint achievements.

The aim of this research was to verify the FMS (Functional Movement Screening) method as apredictor of success in performing gymnastic elements on the floor routine and vault, on aselected sample composed of 36 male subjects aged 20 - 22 years, students of Faculty ofPhysical Education and Sport, University of Banja Luka. A battery of 11 motor skills tests wasassessed: 7 at floor routine (side-to-side and front-to-back cartwheel, roundoff, front and backhandspring, forward and backward flip) and 4 on vault (squat through on the vault and straddlevault with pre-flight, front handspring on vault, roundoff vault) together with FMS resultsall results received normal distribution and a relatively low average FMS value(14.313), which according to many authors is near the limit of the risk of injury (14). The overallresults of the correlation analysis indicated statistically significant relationship between FMSand variables PRENAZ (0.049) and SALNAZ (0.038) at significance level of0.05, while the applied regression analysis gave general information on the prediction modelthat showed statistical significance of 0.03 with the predictor variable FMS at the level of significance0.05. Observing the values of the determination coefficients R2, it was establishedthat the FMS method can predict the performance of the selected gymnastic elements on thefloor routine and the vault as an integral model, explaining about 96% of the common variabilitywith a criterion, representing a significant statistical value.

The Relationship

The present study investigated the relationship between offender type and personality in 21 juvenile males adjudicated for crimes of a sexual nature and 30 juvenile males adjudicated for nonsexual offenses including Possession of Narcotics, Burglary, Criminal Mischief, Assault, and other crimes involving property. Subjects who were aged 13 to 17 years (mean age 15) and committed to the State of Connecticut, Long Lane School, were administered the Minnesota Multiphasic Personality Inventory–Adolescent (MMPI–A). Scores on Psychopathic Deviate and Schizophrenia scales contributed most to the juveniles being classified as sex offenders, whereas scores on Hysteria and Psychasthenia contributed primarily to subjects being classified as nonsex offenders. A single discriminant function attained statistical significance, thereby correctly classifying 77% of the nonsex offenders and 71% of the sex offenders. Results indicate that sex offenders may be distinguished from nonsex offenders according to clinical scales of the MMPI–A.
