Abstract

Penelitian ini bertujuan untuk mengetahui apakah metode latihan Time Control Speed Strength (TCSSM) memberikan pengaruh terhadap peningkatan start reaction time pada atlet sprinter Kota Bandung. Tujuan dari penelitian ini adalah mengetahui peningkatan yang signifikan antara metode latihan Time Control Speed Strength terhadap peningkatan start reaction time pada atlet sprinter. Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Sampel yang digunakan adalah semua  atlet sprint Kota Bandung yang bertempat latihan di Stadion Atletik Padjajaran yang sudah mewakili Kota Bandung dan Jawa Barat dengan menggunakan teknik pengambilan total sampling. Instrumen penelitian ini adalah tes start reaction time dengan menggunakan alat sensor gerak atau balok start elektrik. Berdasarkan analisis dan pengolahan data diperoleh dari hasil output uji paired samples test kelompok eksperimen diketahui nilai sig. (2-tailed) 0.030 0,05. Sedangkan kelompok kontrol diketahui nilai sig. (2-tailed) 0.056 0,05. Dapat disimpulkan bahwa terdapat peningkatan yang signifikan kelompok eksperimen dengan metode latihan time control speed strength terhadap start reaction time pada atlet sprinter Kota Bandung dengan kriteria peningkatan termasuk sangat tinggi dan tidak terdapat peningkatan yang signifikan hasil start reaction time antara pretest dengan posttest pada kelompok control.

Abstract

The purpose of this study was to determine the impact of implementing circuit training through the reverse periodization model on increasing endurance. The research method used is an experimental method using One Group Pre-test Post-test Design. Purposive Sampling was used for sampling as many as 14 samples from UPI female futsal players. The sample did a Pre-test to determine the Power Endurance of each sample, then they were treated with 12 meetings for 4 weeks with Circuit Training, after that the sample did a Post-test to determine the effect of the Treatment. The data processing technique used descriptive data analysis, normality test, homogeneity test, and Paired Sample T-Test test. Research data that has been obtained and analyzed using the Paired Sampe TTest test with the IBM SPSS version 25.0 computer application. The results of the analysis show that there is a significant increase in the impact of the application of the reverse periodization model on increasing the power endurance ability with a sig value. 0.00 0.05. it can be said that there is a significant increase in the impact of implementing circuit training through the reverse periodization model on increasing power endurance capabilities.

Abstract

Abstract This study aims to determine the difference between the application of the drill shooting training method using the instep and shooting using the inside of the foot on the speed and accuracy of futsal shooting for Futsal Athletes at the Bassuran Muda U-16 Jakarta Academy. This research is using experimental method. In this study, there were two groups, namely: the group that applied the drill shooting method using the instep and the group that did the shooting using the inside of the foot on the speed and accuracy of shooting. The sample used in this study were the core players in the Academy Bassuran Muda U-16 Jakarta, totaling 20 people using a proposive sampling approach. The instruments used are pre-test and post-test of shooting speed and accuracy using two shooting stances, namely shooting using the instep and shooting using the inside of the foot. The results of this study indicate that there is a significant effect of drill shooting exercise using the instep and inner foot on increasing the speed and accuracy of shooting futsal, but there is no significant difference in drill shooting exercise using the instep with the inner foot on the speed and accuracy of shooting futsal. on the Futsal Athletes at the Youth Bassuran U-16 Academy in Jakarta

Abstract

The purpose of this study was to determine the relationship between time- motion analysis on the results of the Judo match at the XX National Sports Week (PON) in 2021. The research method used was a descriptive correlational research method. The population used in this study was a video match of West Java Judo athletes who competed at the XX National Sports Week (PON) 2021 in Papua, totaling 15 athletes. The author uses a convenience sampling technique, the author only analyzes West Java athletes who compete in the fighting or sparring category. The research instrument used is videos of Judo matches at the XX National Sports Week (PON) in 2021 in Papua which will be analyzed in time-motion using a stopwatch. Data collection techniques were carried out by analyzing judo match videos. The data processing technique uses three methods, namely descriptive statistics, normality tests, and correlation tests. The results of the study indicate that time-motion analysis does not have a significant effect on the results of judo matches. So it can be concluded that the relationship between these variables has no relationship or is not correlated.

Abstract

This study aims to analyze the relationship between wrist flexibility and arm muscle strength with smash accuracy and speed in badminton athletes of Universitas Pendidikan Indonesia (UPI). In this study using descriptive methods with correlational techniques and the sample in this study amounted to 12 UPI Badminton UKM athletes.. Descriptive statistics show the average wrist flexibility of 99.16, arm muscle strength of 5.01, smash accuracy of 4.25, and smash speed of 103.83. The normality test results showed that the data were normally distributed (p> 0.05). Pearson correlation analysis showed a significant positive relationship between wrist flexibility and smash accuracy (r = 0.640, p = 0.025) and smash speed (r = 0.662, p = 0.019). Similarly, arm muscle strength was significantly associated with accuracy (r = 0.587, p = 0.045) and smash speed (r = 0.720, p = 0.008). However, the regression analysis results showed that these two variables together did not have a significant effect on smash accuracy (p = 0.081) but were significant on smash speed (p = 0.030). The results of this study underscore the importance of wrist flexibility and arm muscle strength in supporting smash performance, both in terms of accuracy and speed. Training that focuses on improving flexibility and arm muscle strength is recommended to help athletes improve the quality of their smashes, while still considering aspects of technique and coordination.
