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

Rowing athlete performance is greatly influenced by aerobic capacity, explosive strength, and precise technical coordination. One strategy widely used to support performance improvement is altitude training, namely training in hypoxic conditions through the Live High-Train Low (LHTL), Live High-Train High (LHTH), and Intermittent Hypoxic Training (IHT) methods. Hypoxic exposure is believed to stimulate an increase in erythropoietin (EPO), which in turn increases hemoglobin (Hb), hematocrit (Hct), and total hemoglobin mass (Hbmass), thereby optimizing the body's oxygen transport capacity. This study aims to systematically examine the effect of altitude training on blood components and the performance of elite rowing athletes. The study was conducted using a Systematic Literature Review (SLR) approach based on the PRISMA 2020 guidelines. Data sources were obtained through the Publish or Perish tool with a publication year range of 2015–2025, and inclusion criteria focused on Randomized Controlled Trial (RCT) studies examining the effects of altitude training on elite rowing athletes. The results of the analysis showed that the LHTL method with a duration of 3–4 weeks and hypoxic exposure of ≥12 hours per day provided a significant increase in Hb, Hct, Hbmass, as well as aerobic capacity such as VO₂max and peak power output. However, there are variations in individual responses between "responders" and "non-responders," as well as differences in study design that cause the results to be inconsistent. Factors such as training intensity, initial fitness status, and nutritional support also influence the effectiveness of the intervention. Therefore, it can be concluded that altitude training has the potential to be an effective strategy to improve the performance of rowing athletes through hematological and physiological adaptations, with LHTL as the most promising method. This research is expected to provide theoretical contributions to the development of sports coaching science as well as practical recommendations for coaches and federations in developing evidence-based training programs.

Abstract

In Indonesia, many industrial companies still pay little attention to the physical fitness of their employees. If physical fitness is not maintained properly, there could be chronic physical illness, which seems to cause middle age to depend on others in their lives, thus affecting their quality of life. Therefore, in order to maintain physical fitness with a small risk of sports injury, it is better to choose water sports because they are safer than sports on land and allow for increased amplitude of movement and energy expenditure for middle age, one of which is aquarobics. Therefore, the researcher aims to examine the effect of aquarobics on the level of physical fitness of industrial employees. 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 industrial employees in Sindang Palay, Rahayu Village, Bandung Regency, totaling 30 people, then the sample used was 7 people selected using purposive sampling techniques. The instruments used are the Harvard step test, sitting standing from a chair for 30 seconds, sit and reach, time up and go, to find out how much the level of physical fitness is. Based on data analysis through paired t test at Alpa 0.05, it can be concluded that there is a significant effect of aquarobic exercise on physical fitness. Thus because of this significance, it can be known that aquarobics can affect the physical fitness of industrial employees.

Abstract

This research aims to analyze the performance of West Java swimming athletes in the 100-meter breaststroke event. This analysis is crucial given the importance of race analysis in competitive swimming and the limited specific studies on the breaststroke at the regional level. Employing a descriptive quantitative approach, performance data from eight athletes (four male and four female) from the West Java Swimming Series 2025 were analyzed. The parameters measured included stroke count, stroke rate, stroke length, time per 10-meter segment, total race time, and speed per segment. The results indicate that DE (male) and AL (female) were the fastest overall swimmers. AL, in particular, demonstrated highly competitive performance, even outperforming several male swimmers. Analysis of split times revealed a progressive deceleration pattern from segment 1 to segment 4 in most athletes due to fatigue. However, DE and AL consistently maintained their speed in the final segments. In terms of stroke count, there was a tendency for an increase from SC 1 to SC 4, while the highest stroke rate was observed in SR 4. For stroke length, SL 1 had the highest average, and Velocity 1 recorded the highest average among the speed segments. Standard deviations indicated better performance consistency among male swimmers compared to female swimmers.

Abstract

Agility is a very important physical component in futsal, where the ability to change direction quickly and accurately determines the performance of athletes on the field. This study aims to determine the effect of the combination of ABC Running Drill and Hexagon Drill exercises on increasing the agility of male futsal athletes. This study uses an experimental design with a pre-test and post-test approach. The study population was male futsal athletes from Al Azhar 5 Islamic High School Cirebon with a sample of 15 athletes. Agility was measured using the Agility T-Test before and after the intervention in the form of a combination of ABC Running Drill and Hexagon Drill exercises for six weeks with 2 meetings per week. The data were analyzed using the Shapiro-Wilk normality test. The results showed a significant increase in agility with a decrease in the average travel time from 13.48 seconds in the pretest to 10.90 seconds in the posttest (difference of 2.58 seconds). All study subjects who were initially in the “poor” category (>12.5 seconds) experienced an improvement in performance with a posttest time range between 9.61-11.84 seconds. The data had a normal distribution based on the Shapiro-Wilk test (p-value > 0.05) and showed a decrease in standard deviation from 5.62 to 3.59, indicating an improvement in performance consistency between athletes. The combination of ABC Running Drill and Hexagon Drill exercises has proven to be effective in significantly increasing the agility of male futsal athletes. This training method can be implemented as an effective training strategy to develop the agility skills of futsal athletes, especially for athletes with low initial agility performance.
