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, Influence of an adapted functional football training in improving the specific-motor performances of football players(Faculty of physical education sport and health, 2020-06) ;Tasevski, Zikica; ; ; The research is was conducted on a sample of 40 football players at the age from 17 to 35 years with the basic aim to establish quantitative transformation changes of the tests for assessing the specific-motoric abilities under the influence of an adapted functional football training with top football players who play different positions in the team. For completing the goals, there were applied six tests of assessing the specific-motoric abilities as follows: zigzag running without a ball (CIK_CAK), zigzag running with a ball (CIK_CAK_T), Ajax test 5 x 10 meters without a ball (AJAKS), AJAX test 5 x 10 meters with a ball (AJAKS_T), Illinois test without a ball (ILINOIS), Illinois test with a ball (ILINOIS_T). The experimental program was being applied during six working weeks with four trainings each week. Trainings were applied with a circular method of work, and the respondents were placed in stations, divided into groups, each of two players. The research results suggest that the six-week experimental training program of an adapted functional football training had a positive effect in improving the average results with the six tests. On the base of the numerical values of arithmetic means and rated differences, it can be concluded that within a six-week period the entire sample of respondents marked improvement with the tests: zigzag running without a ball (CIK_CAK), Ajax test 5 x 10 meters without a ball (AJAKS), Ajax test 5 x 10 meters with a ball (AJAKS_T), Illinois test without a ball (ILINOIS). - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Regression analysis of variables for of situational-motoric knowledge with motoric abilities among female volleyball players in Republic of Macedonia(Faculty of physical education sport and health, 2016-06); ; ; ; Nejic, KThe research is conducted in order to determine the relation and influence of the variables of motoric space (independent variables) on the variables that define personal situational-motoric knowledge (variables as criteria) among female volleyball players in Republic of Macedonia; linear regression analysis applied. There are 8 variables for assessment of motoric abilities which are applied, as well as 4 variables for assessment of situational-motoric knowledge. The achieved results showed that the system of independent variables has statistically significant influence on the following criteria: DPR_4, OPLL. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Could you make a program for basic preparation for me?(Faculty of physical education sport and health, Skopje, 2015-06); ; Realization of the training process should be carefully pre-planned activity. Usually it is taken into consideration the ability of the athletes, that couch would like to modify. The whole idea of the training process should be written and clearly stated in the form of plan. In this way, it is easier to be understood of what, how much and how the couch and athlete work/train. Usually it is an annual plan and it last for one season. Therefore, within one season there are period of basic preparation, than competitive period, and at end is the rest period. When creating the basic preparations, one should take into consideration how much time its needed for realization of them, than when could be organized a friendly matches? When is the first official match? What is the age category of athletes? What is the previous experience of athletes (experienced / if they were in regular training process or not)? The rest is a creation of the author, who should have experience and knowledge of the methods for the transformation of motor skills and their implementation in the "match." - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Coordination burdened Exercises- condition for the proper development of children(Faculty of physical education sport and health, 2016); ; ; ; Choosing the right sports and recreational activities for young age groups is a real challenge. The activities should be adapted to the age, interest, previous experience and abilities of the children that would use them. The coordination as a motor skill is present in every movement. It is directly related to the intellectual abilities. The intellect is needed in order to show the coordination in the movements. Coordination burdened movements are also stimulating the thinking and require consciousness involvement. As an ability, it provides the human the opportunity for self-learning and self-cognition during the learning of the movement and its performance. It is therefore recommended, during the process of creation of activities for the children, to allow them to face the movements they never experienced, that are new for them, but still applicable for their age.
