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

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.

Abstract

This study aims to analyze the effect of small-sided games training with different field sizes on the dribbling skills of 15-year-old soccer athletes. The study used a quantitative approach with a pretest–posttest control group experimental design. The study subjects were 20 15-year-old soccer athletes who were randomly divided into an experimental group and a control group with an equal number. The experimental group was given small-sided games training with varying field sizes, while the control group underwent small-sided games training without varying field sizes. Dribbling skills were measured using a zig-zag dribbling test at the pretest and posttest stages. Data were analyzed using descriptive statistics as well as prerequisite tests and independent t-tests. The results showed that small-sided games training with different field sizes provided more effective dribbling skill improvements than training without varying field sizes. Variations in field sizes created more diverse technical and situational demands, thus encouraging more optimal adaptation of ball control, agility, and player decision-making. These findings confirm that field size adjustment is an important factor in the application of small-sided games in the development of adolescent soccer athletes.

Abstract

Talent identification is a fundamental stage in developing competitive sports because it plays a role in determining the direction of long-term athlete development. In finswimming, the talent identification process requires a specific and multidimensional approach considering the different physical, technical, and physiological demands from conventional swimming. However, finswimming talent identification practices are still often carried out subjectively and have not been integrated into a systematic decision-making model. The goal of this study is to use the Analytic Hierarchy Process approach to perform a comprehensive literature evaluation and synthesis of scientific literature on finswimming athlete talent identification based on important criteria and talents, using a systematic literature review design guided by the PRISMA 2020 framework. The research process involved searching for publications published between 2015 and 2025 in the PubMed, ScienceDirect, and Google Scholar databases using the PRISMA 2020 criteria as a guide. Based on the selection process, four studies were determined to meet the inclusion criteria and a narrative and descriptive analysis was conducted. The synthesis results showed that physical and physiological characteristics, especially muscle strength and aerobic endurance, were the most important factors in determining finswimming skills, with technical and psychological factors coming in second. These findings show how the Analytic Hierarchy Process approach can help identify athletic talent in finswimming in an objective, methodical, and evidence-based manner.
