Item type:Publication, BIOMECHANICAL STATUS AND DEVELOPMENT LEVEL OF FUNDAMENTAL MOTOR SKILLS OF CHILDREN FROM 7 TO 10 YEARS(2013)The research covered a group of fundamental motor skills by defining their biomechanical status and development levels. We analyzed 12 basic motor skills, 6 of which are locomotor and 6 of manipulative type. Skills were analyzed with qualitative biomechanical analysis and then wеre applied appropriate algorithms and mathematical statistical programs for data processing in order to determine their biomechanical status. The research results show that the basic motor skills seen as a whole have expressed heterogeneous biomechanical characteristics. After applying the method of principal components to the results of the qualitative biomechanical analysis, 3 principal components were obtained, while applying the same method to the results of the development level assessment, 4 principal components were obtained. The development level assessment was carried out on 137 male subjects aged 7 to 10 years. Each performance of the subjects was recorded with a video camera and then the presence of performance criteria were registered through predefined qualitative -biomechanical patterns for performance in movement. The data shows that although there was a monotonous increasing trend in the average score in each skill, statistically significant difference was determined in 8 motor skills. Statistically significant difference was determined in the average total score of achievements in locomotor and manipulative skills. In each of the skills the most difficult and the easiest performance criteria were determined. The data indicates a low level of development of the fundamental motor skills that could be attributed to the interaction between the factors individual-environmenttask, especially emphasizing the influence of the environmental factor. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Changes of the maximal strength potential of the flexor muscles in the elbow joint after six weeks of programmed workout with standard and modified repetitive efforts done by the students of the Faculty for Physical Culture in Skopje(Faculty of physical education, 2008-05)The research analyses the changes of the maximal strength potential of the muscles flexors in the elbow joint, as well as the anthropometric measures and bio-mechanic variable covered by the work programme. The conducted workout programme was of longitude character, with time duration of six weeks and two time zones for control of the changes. The same was conducted on 51 students of the Faculty of Physical Culture in Skopje. The students were divided into three experimental groups (previously homogenized), who had tasks to conduct work strength exercises at the Scot’s bench, for the included muscles, with individual outer weight (dumbbell). Each of the groups practices various performance methods of the muscles’ contractions. The first experimental group have worked according to the matrix exercise method. The second experimental group have worked with shortened amplitude in the elbow joint, in the zone from the semi flexion to the maximal flexion and vice versa. The third group assignment was also to work with the shortened amplitudes in the elbow joint, however performed in a manner of maximal extension up to the semi flexion and vice versa. The analysis and the statistical processing of the results (ANOVA/MANOVA) have shown positive changes in the maximal strength capacities within the participants from all three experimental groups. Non-existence of the differences in the results gained by the transversal check (control and final testing), have presented similar behaviour of the strengths capacities of the respondents in each of the groups, although they all have worked under different model of movement performance in the elbow joint. The findings support the transformation programmes of the human performance abilities and are directly focused towards the modification of the strength component. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, COMPARISON OF CHANGES IN THE MUSCLE STRENGTH POTENTIAL OF ELBOW FLEXORS AND EXTENSORS IN ADOLESCENTS FOLLOWING A SIX-WEEK PROGRAMMED EXERCISE WITH MODIFIED REPETITIVE MUSCLE LOADS(Faculty of physical education, 2012-12)The research analyses and compares the changes of the maximum strength potential, isokinetic parameters and measures for anthropometric indicators realised in accordance with standard methods and echo sonography, between flexor muscles and extensor muscles, as well as the genetic predisposition for strength capacity development of the subjects. The experimental procedure included 21 subjects, divided into 3 experimental groups, pilot research homogenised. Individually focused programme for maximum strength capacity was realised, through exercises on Scott bench for the elbow flexor and extensor muscles during a 6-week period. The first group worked in a classic method, loading the muscle tissue along the entire elbow amplitude. The second group worked in an elbow reduced contractions methods in conditions when the muscle tissue exhibits maximum load. The third group also worked in a reduced contractions method, but in conditions when the muscle tissue can endure maximal external load. Statistical analysis showed positive effects of the experimental programme for transformation of the maximal strength capacity for both muscle parties in the three experimental groups. Data obtained from the three control points speak of similar tendency of the three experimental groups, although the subjects carried out different tasks. The elbow flexor and extensor muscle groups endured similar strength capacities transformation. The hypothesis on the association of strength capacities with the ACTN3 genotype was not confirmed from the muscle tissue genetic dominance analysis. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Влијание на прекумерната телесна тежина врз антропометрискиот, биомоторичкиот и функционалниот простор кај ученичките од петтите одделенија во Скопје (магистерски труд)(Faculty of physical education, sport and health, 1996)Shukova Stojmanovska D.The quantitative and structural influence of overweight on the manifest and latent anthropometric, biomotor and functional space, as well as the predictive influence of the latent anthropometric dimensions on the manifest and latent biomotor variables and the manifest and latent variables for estimating cardio-respiratiry function. First all students were divided into 11 groups according to their height, with a difference in height of up to 4 cm, and then for each group the average weight for the corresponding height was calculated separately. Then, from 1100 students from the fifth grade from 24 primary schools in Skopje, a total of 435 students were selected, which were divided into three groups. In the first group were students whose weight was 90 to 110% of the average weight for the appropriate height (students with normal body weight - H = 150), in the second group were students whose weight was 110 to 130% of the average weight for the appropriate height (students with first degree of obesity - H = 146) and in the third group were students whose weight was over 130% of the average weight for the appropriate height (students with second degree of obesity - H = 139). On such a stratified sample, we applied 15 anthropometric, 13 biomotor and 9 variables for estimating cardiorespiratory function. Within each group, as well as for the three groups together (H = 435), the latent structure in the three mentioned spaces was determined. Quantitative and structural intergroup differences in the manifest and latent space were determined with the help of univariate and multivariate analyzes (T-test, ANOVA, MANOVA and discriminatory analysis). In addition, the predictive influence of manifest and latent anthropometric variables on biomotor and cardiovascular capacity assessment variables was determined by regression analysis. With the help of factor analysis, the latent structure in the anthropometric, biomotor and functional space in all subgroups and in all students together was determined. Based on the obtained results, it can be concluded that among the three groups of students, there are statistical significant differenences in both manifest and latent variables. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Различниот статус на телесната маса и нејзините импликации врз антропометрискиот, биомоторичкиот и функционалниот простор кај ученичките од вишите одделенија на основните училишта (VI-VIII) од Скопје (докторскиот труд)(Faculty of physical education, sport and health, 1999)Shukova Stojmanovska D.The quantitative and structural influence of different body mass status on the manifest and latent anthropometric, biomotor and functional space, as well as the predictive influence of the manifest and latent anthropometric, biomotor and functional dimensions on the manifest and latent functional characteristics are investigated. For that purpose, we conducted a longitudinal survey of 900 students from VI, VII and VIII grades from 22 primary schools in Skopje. They were divided into three groups: malnourished, normal body weight and obese, with different numbers of entities in each subgroup and in each age separately. The division into three subgroups was made with the help of our BMI modification, to which we added the average value of 6 skin folds. We decided on this modification after factorization of 16 existing methods and indexes, which in the current practice are used for selection in relation to body weight. We applied 21 anthropometric, 13 biomotor and 9 functional variables (to estimate cardiorespiratory capacity) on this stratified sample. Within each of the three groups, the latent structure of the three mentioned areas was determined. Quantitative and structural intergroup differences in each age and for each sub-sample in the three ages were determined with the help of univariate and multivariate analyses (T-test, ANOVA, MANOVA discriminative analysis). In addition, the predictive influence of the manifest and latent anthropometric, biomotor and functional dimensions over manifest and latent biomotor and functional characteristics were determined by regression analysis. Based on the obtained results it can be concluded that between the three groups of students, in the three spaces and in the three different ages, there are a number of statistically significant quantitative and structural differences.
