Item type:Publication, Changes in the Muscle Strength of the Elbow Flexors Following a Six-week Experimental Procedure in Adolescents Monitored Through Isokinetic and Motor Tests(Acta Inform med, 2014-06); ;Handjiski Zoran,Handjiska Eli,A group of 7 subjects underwent an experimental procedure which studied the potential changes in the maximal strength of the non-dominant arm elbow flexors. The programme duration was limited to 6 weeks during which the subjects practiced exercises 3 times a week, 3 series, on a Scott bench. Individual approach was applied to the external load and it was designed so that the weight being lifted would increase if the number of lifts in one series would exceed 3. The subjects were monitored through the one-repetition maximum 1 RM motor test and the isokinetic tests performed on biodex system, tested in 3 time periods (at the beginning, after 3 weeks, and after the 6th week). Of the 6 isokinetic tests, only the test for the maximum torque and the time for achieving the maximum torque have shown statistically important changes in terms of reduction in values, which was not expected. The one-repetition maximum test, unlike the isokinetic tests, has shown statistically important increase of the maximal muscle strength of 32.1% after the third week of exercising, and 46.8% after the six weeks of exercising. The statistical test for the correlation between the two variables has shown low correlation between these two tests. The values of the data of the two test types have not shown any correspondence among the subjects possibly due to the type of performance of the maximal muscle load during exercises, performed in conditions identical to the one-repetition maximum test, with similar and yet differ- ent conditions in the case of isokinetic tests. Most probably, due to the conditions in which the exercises and the tests took place, there is difference in the obtained results. - 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, Force platform - testing and diagnosis in sport and physical activities(Faculty of physical education sport and health, 2017); ; ; Force platform is one of the most used instruments for assessing movements in sports, physical activity and medicine. It is primarily used to measure the ground reaction force. Today, various types of platforms are present in the testing and diagnostics depending on their technical and physical characteristics. Knowledge of its functioning and the ability to understand and interpret the results is crucial for those who use this tool. The text first lists the general and technical characteristics of the platform, and then provides practical examples of its application. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Workload Ratio Assessment in Football: Evaluating Simple and Exponential Moving Averages(Research in Physical Education, Sport and Health, 2024); ;Sejkeroski Mihailo ;Nuno André Nunes ;Soklevska, Ilievski, ElenaIntroduction: To identify the optimal technique for examining time series data related to the Acute Chronic Workload Ratio (ACWR), correlations between the Simple Moving Average (SMA) and the Exponentially Weighted Moving Average (EWMA) were investigated in this study utilising a decay factor (λ) over a period of 7/28 days. Five GPS metrics were included in our analysis: Total Distance, Accelerations, Decelerations, High Metabolic Load Distance, and Distance in Speed Zones 3+4+5 (>19,9 km/h). These data points were collected from 22 players across 47 days, excluding the first 28 days, for a total of 596 data points per pair [SMA/EWMA]. Methods: Shapiro-Wilk and Kolmogorov-Smirnov normality tests were performed on the SMA and EWMA datasets prior to using the Spearman, Kendall Tau, and Distance Correlation techniques to assess correlations and dependencies between pairings. Using Python and libraries including Pandas, NumPy, Matplotlib, SciPy, Scikit-Learn, Statsmodels, OpenPyXL, Dcor, and IPython.display, the analysis was carried out in Anaconda's Jupyter Notebook. Results and Discussion: Significant departures from the normal distribution were shown by normality tests (p<0.05 for most of the variables). With p-values of 0.00, Spearman analysis showed significant correlations for every pair of variables, ranging from moderate (0.46) to somewhat weak (0.23). Additionally, Kendall's Tau revealed statistically significant correlations (p=0.00) across strengths, ranging from moderate (0.32) to weak (0.16). With values ranging from 0.25 to 0.44, Distance Correlation showed significant connections (p<0.00), while Energy Distance values displayed a range of discrepancies. Interestingly, EWMA frequently displayed values that were marginally lower than SMA, highlighting a significance level of p=0.00. Conclusion: The results show continuous trends and modest to moderate positive correlations between the variables under study. Both SMA and EWMA can be used with the help of distance correlation. EWMA is typically chosen for responsive trend analysis and offering a realistic representation of current conditions in ACWR monitoring due to its emphasis on recent data. The decision between SMA and EWMA, however, may change depending on the coaching needs; in this study, EWMA approaches produced somewhat lower scores than SMA. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Comparison of changes in the muscular power potential of elbow flexors after a six-week experimental procedure with two groups of subjects working according to the standard load method and the greatest muscle load method(Faculty of physical education sport and health, Skopje, 2014); ; Saiti, AThe six-week programme for improvement of the elbow flexor muscles strength was carried out on 14 subjects, divided into two experimental groups (E1 and E2) in order to assess the potential maximal strength changes. The first group worked according to the standard method of muscle contraction – entire amplitude in the elbow. The second experimental group worked according to the method of reduced angle of muscle contractions within an amplitude of maximal extension and 30⁰ to flexion in conditions when the muscle shows greatest muscle load. Each of the subjects exercised 3 times a week, performing 3 series on the Scott bench with one-arm weight as external load and one to three repetitions in each series. The programme, according to which the trainings were carried out, was performed with individual approach. In each series, the weight with which each of subjects exercised, changed (increased) in reference with the number of repetitions in single series, but with no more than 3 repetitions. Individual changes in each of the groups were analysed, as well as the inter-group differences for all tests. Results have shown a statistically significant increase of the maximum strength of the elbow flexor muscles of 32,1% after 3 weeks of exercises and 46,8% after six weeks of exercises in E1, and 27.9% after the third, and 43.6% after the sixth week in E2 (tested with the 1RM test). The inter-group differences tested after the third, and after the sixth week, have shown no statistically significant differences, which means that although the subjects of both groups worked with different amplitudes of muscle contractions, they have still achieved statistically identical changes in the maximal strength component of the affected muscle groups. This individual approach method, as well as the reduced amplitudes of exercise of the maximal strength of the flexor muscles, enables a fast and efficient change of this capacity and may have an application in the field of sports, recreation or rehabilitation. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Determination and comparison of the qualitative biomechanical status of the motor stereotips in handball with two methodological approaches(Faculty of physical education sport and health, 2016-06) ;Trajkovski, T; ; The knowledge of the biomechanical characteristics of the sports technique is one of the most important stages in the determination of the key aspects of the performance, through which more rational and more efficiant approach is enabled in its study and improvement.The objective of this research is to determine and compare the qualitative biomechanical status of the motor stereotypes from the sports game handball by applying two methogological approaches. The sample of motor stereotypes is analyzed with the method of qualitative biomechanical analysis through an application of binary and ordinal data, followed by determination and comparision of the biomechanicl intersimilarity, the complete biomechanical similarity, the adjacent biomechanical similarity, the force of the biomechanical connection and the biomechanical structure.The obtained results indicate presence of a similar interpretability in the two approaches for determination of the biomechanical status. Still, in terms of the biomechanical structure, the orthogonal and the skew solution provide a clearer structure and interpretability in the ordinal approach.Further research is required for more reliable generalizaton, which will also include other approcahes both in the qualitative biomechanical analysis, as well as in the methodology, through which the biomechanical status of the motor stereotypes would be determined and compared. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Alpine climbing as a sport(Center for physical education at Faculty of physical education, Skopje, 2009)Most frequent explanation about alpinism and believes that it is not a sport is coming from the directions and thoughts that believe in the following paradigm “within alpinism there is no agonism”. Alpinism is an activity where individual person is left on his own to overtake the obstacle, to be more precise to climb the rock or the mountain. There is no other person or subject in general to compete with. Defining the physical activities through the terms of sport and recreation means, putting some borders of the meaning of these activities. Definitions should follow the contemporary thoughts and news as well as the new directions. Bordering, by its meaning, is losing a freedom, and especially for the activities that would be not at all productive. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Relation between the standing vertical jump (Abalak test), standing long jump, and squat jump 2 legs 5 jumps (optojump) tests for assessment of the explosive strength of legs(Faculty of physical education sport and health, 2016-06); ; ;Klincarov, Ilija ;Starc, GregorSejkeroski, MihailoThe purpose of this study was to assess whether and if there is correlation between the applied tests for explosive strength of legs, so as to provide a recommendation when selecting tests for assessment of the explosive strength of legs. The subject of this research is the explosive strength of legs, tested at 36 examinees, male, age of 18-19 years. Three tests were executed: 1. standing vertical jump (SKOKVIS) – Abalak test , 2. standing long jump (SKOKDAL), 3. squat jump 2 legs 5 jumps – with optojump equipment. The examinees were divided into 3 groups. Each of the groups was randomly distributed in one of the 3 test places. Breaks of 5 minutes per examinee were given between tests. During testing, for the Abalak and standing long jump tests, the examinees have performed 2 attempts, and one attempt for squat jump 2 legs 5 jumps. The jump 2 legs 5 jumps test on optojump equipment was executed with hands on hips. Pearson’s analysis was performed on the results of Abalak, standing jump and heights of optojumpt tests, as well as a multiple regression during which, as predictor variables, the output data were taken of the tests with optojump, for 1-contact time with surface (T.Cont), 2-flight time (T.Flight) and 3-Power as a output from the jumps, and the criteria results of Abalak, standing jump and heights of optojump. The Pearson’s analysis has shown significant correlation between the results of the Abalaks, standing jump and heights of otpojump tests. Highest correlation (r=0.638, p=0.000) exists between the tests Abalak and standing long jump. Lowest, yet significant, correlation exists between Abalak and the height resulting from the optojump test r=0.466 (p=0.002). In the first multiple regression analysis where height is dependant variable, the entire system of predictor variables contributes to the analysis in a statistically significant manner (R=0.99, p=0.000). In case of a SKOKVIS dependant variable, the system of predictor variables, again, has statistically significant impact in the analysis (R=0,519, p=0.017). In this case, single contribution to significance is attributed to the variable T.Flight (p=0.017). In the third multiple regression for the dependent variable SKOKDAL, the analysis is statistically significant (p=0.007), and, once again, the main (single) variable for significance is T.Flight (p=0.03). Existence of correlation between the three included tests in this research has shown that, in method-related terms, tests are efficient when assessing the explosive strength of legs. Presumably, it can be recommended that those who shall apply the tests for explosive strength in legs shall have to choose the test they shall systematically apply, so as to show whether there are any changes of this ability following a treatment with exercises. One can conclude that, perhaps the time spent in the flight phase can in some way be used as a predictor on the reached height, during the testing of the standing vertical jump and the standing long jump. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Planning of microcycle in football- dosaging of the training load - #2(Faculty of physical education sport and health, 2021-06); ; ;Tasevski Zikica; Brazhanski OgnenIn the process of planning/ modeling training programs, repetitive training periods are used, in the form of cycles (weekly, monthly, annual). This is done in order for the coach to present clearly the idea for the training program, and also to allow the athlete's biorhythm to adapt to the competition’s cycles. When creating a training cycle in football, the components of the training such as intensity, volume, weekly training frequency as well as rest, during and after the training, are always taken into account. We usually talk about the 7-day micro cycle, as the shortest period of planning the training program. This micro cycle can be organised in several variants: in the preparatory period, or in the period of competition, where there can be one or two matches in seven days. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, SELF-ASSESSMENT AMONG SKI INSTRUCTORS WITH DIFFERENT LEVELS OF BASIC ALPINE SKIING SKILLS(Science and Research Centre Koper, Slovenia, 2020); ; ; ; Kiril, NaskovSki instructors need to have adequate knowledge and skills in assessing sports techniques as a condition for successful intervention that will lead to improved performance. The purpose of this research was to assess how instructors with different levels of performance evaluate their skiing skills. A total of 58 Instructor candidates were rated with a score of 1 (lowest) to 5 (highest) by Examination Board in 7 elements of basic alpine skiing technique: Gliding straight (basic position), Wedge swinging, Wedge curves, Basic turn, Basic swinging, Wide corridor and Narrow corridor. After the practical exam, all candidates completed a self-assessment form on the same scale of 1 to 5 for each individual skiing element. The average practical grade of all seven skiing techniques, awarded by the Examination Board, was taken as a criterion for grouping. Three groups of high, intermediate and low skiing level were defined. The high performance group consisted of a total of 16 candidates with an average grade above 4. The mid-level group consisted of 26 candidates with an average grade between 3 and 4, while the low-performance group comprised 16 candidates with an average grade below 3. The results obtained from the Examination Board and the Self-Assessment were compared to determine the degree of coincidence expressed as a percentage difference between these two scores. From the results obtained, there is an evident difference in the objectivity of the self-assessment between groups. The high performance group showed the smallest percentage difference (9.79%) in the scores obtained by the Examination Board and the Selfassessment.The mid-level group showed a percentage difference between the two scores of 21.95% and the low-performance group of 54.04%. The high-performance group was recorded also by several individuals who underestimated their performances, which is not the case with the other two groups. There is a significant overrated self perception in the intermediate group and especially in the low skills group. The conclusion is that the higher level of performance increases the degree of objectivity of self-assessment. This rate of self-estimation and awareness of body position is probably due to the higher skiing experience of the candidates with the highest level of performance.
