However, at the same time, teachers have not maximized analytical thinking supplements in learning and mastering student movements to optimize their physical education learning outcomes. This research used quantitative methods to examine the effect of analytical thinking skills on student learning outcomes. The participants were 24 elementary school students (mean age = 10.17+0.38) who were determined using a purposive sampling technique. Data on thinking skills were collected using instruments and rubrics for assessing analytical thinking skills. While the learning outcomes data use the final value of physical education learning. Data analysis used descriptive statistics and simple linear regression analysis. Descriptive analysis showed that students' analytical thinking skills were moderate (58.34%), and learning outcomes were good (100%). There is a significant influence between analytical thinking skills on student learning outcomes (t = 2.312, α = 0.031) with a determination value of 19.6%. Considering the essence of analytical thinking skills for learning outcomes and supporting students' life skills, the orientation of physical education learning outcomes parameters and the comprehensive and sustainable integration of analytical thinking into students' physical activities must be discussed further.","PeriodicalId":473532,"journal":{"name":"Jurnal Keolahragaan","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135132184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this research is to produce learning media in the physical education measurement test subject based on interactive multimedia, with product results in the form of mobile applications, interactive VCDs, printed books, and indexed reputable international journals which will later be used both in learning activities and in independent learning to facilitate in delivering learning material for physical education measurement tests. This study used the research and development approach from Borg and Gall. The target products or users in this study were lecturers in the sport’s physical education measurement test course. The subjects in this study were all PJKR FIK Unimed students who took the sport physical education measurement test course. The findings of the small group test showed that the questionnaire product had a total score of 565, an average of 28.25, and a total percentage of 70.62% in a small trial with a fairly valid category (used). The product could thus be used in this study, but the authors chose to carry out a large group trial to validate the product. Based on the findings of the large group test, the product questionnaire has a total score of 1369, an average of 34.22, and an overall percentage of 85.56% in a small trial with a very valid (used) category.

Motor competence stimulation focus on measuring the physical activity of playing games. The study investigated the potential improvement of motor skill by playing net games. Through the study, students are taught to make important decisions and acquire tactical knowledge by simplifying complex games. This research adopted an experimental design using One Group pretest-posttest method. Samples were collected through random sampling method in two classes of a selected elementary school. The Games Performance Assessment Instrument (GPAI) and the Gross Motor Development Test version 2 (TGMD-2) were used to assess students' playing understanding, motor skills, and numeric knowledge. Utilizing quantitative descriptive analysis, data were examined. The findings showed that the posttest values for motor skill aspects (95) were greater than the pretest results (88, 5). The average increase of each component for playing game was execution skill of 0.05, decision-making of 0.04, opponent coverage of 0.03, and overall of 0.05. Different test results show that t-test (t=4.50), both for game understanding and motor skill aspects, which were greater than t-tables (1,796). The statistics showed that the skills after treatment were significantly different from the students’ ability before treatment. This improvement in decision-making, technical execution, cover, support, game performance, game participation, pleasure, perceived competence, and intention to engage in physical activity is attributable to the usage of net games. The conclusion is that the use of net games is effective in improving the motor competence of elementary school students. However, the study only involves a small number of students, hence it is recommended for including a larger number of students in the further research, as well as using more rigid study design (control group) and take in different elementary schools.","PeriodicalId":473532,"journal":{"name":"Jurnal Keolahragaan","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135132193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of one training method is common, and the use of a combination of two training methods is something new in training. The purpose of this study was to reveal the effectiveness of the combination of split jump training as a plyometric exercise with short sprint training on the leg muscle power capacity and agility of volleyball players. The research method in this research is a quasi experiment involving 40 samples (age: 20.85 ± 0.89 years, height: 178.69 ± 6.51 cm, and weight: 72.47 ± 8.02 kg). This study used a modified randomized pre-test and post-test design without a control group. The population of this study were volleyball players at Universitas Pendidikan Ganesha (Undiksha). Purposive sampling was chosen to determine the sample, namely 40 male student players.The sample was given training combining split jumps with short sprints for 4 weeks with details of 12 training sessions (3 times a week). The Jumpa DF and agility t-test were chosen as instruments to measure leg muscle power and agility. The collected data was analyzed using a paired t-test with a significance level of 5%. Before testing the hypothesis, start by testing the normality of the data using the Kolmogorov-Smirnova test and the homogeneity of the data using Levene’s with the help of SPSS 16.0. The results achieved show that there is a significant influence on the leg muscle power (sig 0.05) and agility (sig 0.05) of volleyball players. Based on the results of this data analysis, it can be concluded that the combination of split jump and short sprint training for 4 weeks has a significant effect on the results of leg muscle power and agility in male volleyball players. Seeing the findings above, it is hoped that volleyball coaches can apply this training method, specifically in the pre-competition phase, which requires a short time to improve leg muscle strength and agility at the same time.","PeriodicalId":473532,"journal":{"name":"Jurnal Keolahragaan","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135132040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
