Abstract

This study aims to determine the effect of circuit training on T-kick speed in pencak silat athletes. The method used is a quasi-experimental with a pretest-posttest control group design. The sample consisted of 20 athletes who were randomly divided into two groups: experimental and control. The experimental group underwent a circuit training program for four weeks, while the control group underwent conventional training. Kick speed measurements were carried out using Kinovea software. The results of the Paired Sample t-Test showed a significance value of 0.000 (p <0.05), which indicated a significant increase in the experimental group. The average T-kick time decreased from 0.76070 seconds to 0.64250 seconds. This study shows that circuit training can significantly increase kick speed by increasing leg muscle strength, neuromuscular efficiency, and motor coordination. These findings contribute to the development of more specific and technology-based training methods in pencak silat.

Abstract

The purpose of this study is to examine whether there is a significant effect of jack knife stretching and Nordic hamstring exercise on the hamstring muscle flexibility of futsal extracurricular students at state junior high school 7 Cimahi, and to determine whether there is a significant difference in the effects between jack knife stretching and Nordic hamstring exercise on the hamstring muscle flexibility of these students. The method used in this study is an experimental method with a Two Groups Pretest and Posttest Design. The population in this study consisted of 22 male students from state junior high school 7 Cimahi who participated in the futsal extracurricular program. The sample also consisted of 22 students, selected using the total sampling technique, which means the entire population was used as the sample. The sample was then divided into two groups using the ABBA formula. The treatment was conducted over 15 sessions (3 times per week). To measure hamstring muscle flexibility, the researcher used the Sit and Reach Test instrument. The Shapiro-Wilk test was used to test data normality, the Paired t-test was used to test the effect, and the Independent t-test was used to compare the effects. The results after the data analysis, a significance value of 0.000 was obtained, indicating that there is a significant effect from the treatment of jack knife stretching and nordic hamstring exercise. Data analysis showed that there was no significant difference in the effects between jack knife stretching and Nordic hamstring exercise. It can be concluded that both jack knife stretching and Nordic hamstring exercise have an effect on hamstring muscle flexibility.

Abstract

Evaluating the effectiveness of training programs by monitoring athletes’ skills makes a crucial contribution to endurance sports such as road cycling. The purpose of this study was to examine the effect of polarized training on FTP (Functional Threshold Power), which is defined as the maximum power that an athlete can maintain for approximately 60 minutes. There were 5 expert cyclists aged 17-20 years from ISSI Kota Bandung, involving pre-test and post-test stages using an experimental method. 80% of the training sessions were low intensity, with the remaining 20% being high intensity, and participants had to follow a polarized training schedule for a period of 6 weeks. A Wahoo KICKR smart trainer with MyWhoosh FTP20 settings was used to assess FTP. A t-test was performed after a Shapiro-Wilk test to check whether the data was normally distributed or not in the statistical process. Outcomes indicated a substantial FTP improvement, rising from 3,514 to 3.820 W/kg (t = -6.372, p = 0.003 < 0.05). Polarized training significantly increases FTP among road cyclists, as shown in these findings. This demonstrates that the use of polarized intensity allocation is a scientifically proven approach to increasing FTP, an essential measure of cycling skill or ability marked by FTP.

Abstract

The purpose of this study was to examine the effect of Drag Flick Drill Training on the shooting accuracy of the boys’ indoor hockey team at State Senior High School 14 in Tangerang Regency. The researcher used an experimental method to prove the effect of a treatment on the outcome of that treatment. This study used a one-group pre-test post-test design. This research design involved measurements through a pre-test administered before the treatment and a post-test conducted after the treatment was given to the sample. The researcher took a population of 27 students and a sample of 13 students. The treatment was given 8 times, twice a week. The sampling technique used in this study was purposive sampling, with the characteristics of the research sample being 13 male students in grade X at State Senior High School 14 Tangerang Regency who had just participated in the indoor hockey extracurricular activity. The instrument used in this test was a Target Game. The results of this study showed a significant effect of Drag Flick Drill Training on the shooting accuracy of male students participating in indoor hockey at State Senior High School 14 Tangerang Regency. Through these drills, students also show greater courage in making decisions to shoot. In addition, students who are able to achieve a high shooting percentage are generally supported by the consistent application of drag flick drills in the training process. It can be concluded that Drag Flick Drill Training has an effect on shooting accuracy.

Abstract

This study investigated the effect of integrating scanning into a diamond passing training program on the passing accuracy of U13 football players at SSB Saswco FC Bandung. We used a quantitative quasi-experimental method with a one-group pretest–posttest design. Total sampling was used to choose all 20 eligible 13-year-old players. Prior to and following a four-week intervention (three sessions per week for sixty minutes each), passing performance was evaluated using the Loughborough Soccer Passing Test (LSPT). We used a paired-samples t-test, the Shapiro-Wilk normality test, and effect size computation to compare pretest and posttest results. The results showed that as LSPT scores decreased from the pretest (M = 64.10, SD = 5.04) to the posttest (M = 60.90, SD = 4.13), passing performance improved. The paired-samples t-test showed a significant improvement following the intervention (t(19) = 8.587, p < 0.001) with a very large effect (Cohen’s dz ≈ 1.92), and the normalcy assumptions were satisfied. The paired-samples t-test showed a significant improvement following the intervention, t(19) = 8.587, p < 0.001, with a very large effect (Cohen’s dz ≈ 1.92), and the normality assumptions were satisfied. These findings suggest that embedding scanning cues within diamond passing drills is an effective approach to enhance passing performance in youth players by combining technical execution with perceptual–cognitive decision-making demands.
