Abstract

Plyometrics is an explosive physical training method used to increase power output, force production, and speed. Plyometrics is a way to push muscles to achieve maximal strength quickly and thus serves to increase explosive-reactive power through a variety of movements and is a popular training approach. Therefore, plyometric training is expected to have an effect on the results of the starting jump distance, and researchers aim to study more deeply the effect of plyometric training on the results of the starting jump distance in swimming. This study uses a quantitative approach with an experimental method with a One Group Pretest-Posttest Design research design. The population in this study involved 70 Tritons swimming club athletes located at the Horizon Swimming Pool, Bandung City, then the sample used was 15 people selected using purposive sampling techniques, with the instruments used being taken from the results of measuring the distance of the swimming start jump with the Kinovea application. The data were processed and analyzed using a normality test withShapiro Wilkthen analyzed using the T test with SPSS 25. The T test value is with a Sig. (2-tailed) value of 0.000, based on the test results, the Sig. (2-tailed) value <.05 so that H0 is rejected. then it can be concluded that there is a significant influence between plyometric training on the results of the start jump distance of swimming sports. Thus, because of this significance, it can be seen that plyometric training can affect the start jump distance of swimming sports.

Abstract

This study examines the impact of static stretching on flexibility improvement in Taekwondo athletes. Specifically, the purpose of the research is to observe the effects of implementing this method over 14 sessions (conducted three times per week). The research method used is an experimental design with a one-group pretest-posttest design. The sample in this study was selected using purposive sampling, consisting of 12 athletes. To measure flexibility, the study employed the Maximal Hip Flexion Activation Knee Extension (MHFAKE) test. Quantitative data were analyzed using the Wilcoxon test. The results show that static stretching significantly improves flexibility, with the average score increasing from 35.83 to 21.66 (50.00%). The Wilcoxon test indicated a p-value of 0.002 < 0.05, meaning the alternative hypothesis (Ha) is accepted, and there is a significant effect. In conclusion, static stretching has a significant impact on the improvement of flexibility in Taekwondo athletes' muscles.

Abstract

In the field of sports coaching, research urgently needed that is closely related to achievement. Specifically, in the field of sports psychology, there is still a great need for research that specifically examines ideas that can be used as input for those who need them. The purpose of this study is to examine developments regarding sports psychology research, especially aspects of psychology that are currently developing rapidly through a bibliometric approach using a computerized mapping analysis application using VOSviewer. Apart from that, this research hopes to identify existing research trends in the field of sports psychology. Various article data obtained were sourced from Google Scholar using the Publish or Perish Reference Manager application. The keywords used to guide the search process in this research are “Psychological Aspects on Athletes”. During the search, the author found 988 articles relevant to the keyword. The articles obtained came from a span of 10 years, namely 2012-2022, and came from various journals and publishers. If explained one by one the published articles related to the psychological aspects of athletes from year to year will be obtained as follows: 55 articles in 2012, 62 articles in 2013, 69 articles in 2014, 73 articles in 2015, 73 articles in 2016, 74 articles in 2017, 89 articles in 2018, 119 articles in 2019, 140 articles in 2020, 132 articles in 2021 and 102 articles in 2022. Judging from the data, it can be seen that there has been an increase and decrease from year to year and we checked all of this using VOSviewer. The results of this study will help future researchers regarding sports psychology, especially aspects of psychology in sports, in finding sources, studies, and theories that are relevant to their research. However, this research still has limitations in using the application, so it is recommended to use other applications that make it possible to obtain further results.

Abstract

There are main factors that can reduce the level of competitive anxiety in athletes, namely mental toughness, this is proven in research on other sports but has not been done in the sport of diving. This study aims to examine the significant relationship between mental toughness and competitive anxiety of diving athletes in the training phase. The method used is descriptive correlation using the Sport Mental Toughness Questionnaire (SMTQ) instrument and the Sport Competitive Anxiety Test (SCAT) questionnaire. The research sample amounted to 24 diving athletes at the West Java level, Data collection through google form in the form of questionnaires and data analysis techniques with SPSS version 26. The results of data analysis show that there is a significant negative relationship with a pearson correlation value of -0.415 with a Sig value. (2-tailed) 0.044 Based on the test results, the value of Sig. (2-tailed) <0.05 so that H0 is rejected. This study concludes that there is a significant relationship between mental toughness and competitive anxiety in the training phase

Abstract

The purpose of this study was to analyze the performance of artistic swimmers from West Java using video as a more objective evaluation tool. Athlete performance has usually been assessed directly, which can lead to subjectivity. Kinematic analysis was used for data from three female athletes from qualifying round of the 2025 West Java Provincial Sports Week and the 2025 West Java Regional Sports Championship . Leg height index (LHI) and average leg angle deviation (LAD) in vertical and knight movements were calculated using Kinovea software for frame-by-frame data extraction. The LAD was calculated based on the angle deviation from the ideal position, and the LHI values were compared to the FINA standard height card. The analysis results show that there are quite noticeable technical differences between the subjects.  SSK a showed the best and most consistent performance, with an average LHI of 9.5 (Vertical) and 9.6 (Knight) that was closer to the FINA standard, and her LAD was also relatively small on both elements. AEN demonstrated a stable LHI (9.1 Vertical; 9.2 Knight). Compared to other athletes, AEN LAD values tended to be higher, which may indicate that she reached sufficient height to make utilizing the angles around her peak more difficult. Meanwhile, LNL achieved a lower LHI (9.1 Vertical; 8.9 Knight) as well as the smallest LAD value in the Knight movement (1.3°). Although her vertical LAD (5.9°) was higher than AEN. The results indicate that video-based performance analysis can be successfully applied to the evaluation of artistic swimming performance.
