Kelincahan atlet sepak bola U-14-15 memiliki rata-rata sebesar 18,38 detik dan atlet bola voli U-14-15 sebesar 19,89 detik. Hasil penelitian pada kecepatan pada atlet sepak bola U-13-14 tahun memiliki rata-rata 4,56 detik dan atlet bola voli U-13-14 tahun sebesar 5,35 detik. Variabel kelincahan atlet sepak bola usia 13-14 tahun memiliki rata-rata kelincahan sebesar 18,88 detik dan atlet bola voli usia 13-14 tahun sebesar 19,16 detik. Berdasarkan hasil analisis data tersebut dapat disimpulkan bahwa bahwa, kecepatan dan kelincahan atlet usia muda pada cabang sepak bola lebih baik jika dibandingkan dengan cabang bola voli. Permainan bola voli lebih stasioner dan dengan terbatas gerakan di ruang yang lebih kecil, sedangkan permainan sepak bola  memiliki lebih banyak ketidakpastian di ruang yang lebih besar. Parameter antropometri juga memainkan peran yang signifikan terhadap variabel kelincahan, misalnya, karena pentingnya dimensi tubuh dalam hasil tes motorik, yaitu, tinggi badan, panjang kaki, atau indeks massa tubuh.This study aims to compare the physical condition of speed and agility of young football and volleyball athletes. This research is a comparative study with a sample, namely, FIKK UNY Sports Laboratory school athletes in football and volleyball aged 13-14 and 14-15 years, totaling 87 players. A comparative study will be carried out by collecting data by assessing physical condition by the trainer. The instrument for assessing physical condition is speed by carrying out a 30 meter sprint test, and agility using the Illinois Run Agility Test. The collected data will be analyzed using a t-test according to the nature of the data. Based on the results of the research above, it can be seen that the average speed of soccer athletes aged 14-15 years (U) is 4.52 seconds and for volleyball athletes it is 5.08 seconds. The average agility of U-14-15 football athletes is 18.38 seconds and that of U-14-15 volleyball athletes is 19.89 seconds. The results of research on speed for U-13-14 year old soccer athletes were an average of 4.56 seconds and for U-13-14 year old volleyball athletes 5.35 seconds. The agility variable for soccer athletes aged 13-14 years has an average agility of 18.88 seconds and volleyball athletes aged 13-14 years is 19.16 seconds. Based on the results of the data analysis, it can be concluded that the speed and agility of young athletes in soccer are better than in volleyball. Volleyball games are more stationary and with limited movement in smaller spaces, whereas soccer games have more unpredictability in larger spaces. Anthropometric parameters also play a significant role on agility variables, for example, due to the importance of body dimensions in motor test results, namely, height, leg length or body mass index.

Abstract

The training model in improving a pencak silat athlete's abilities is an important factor, because an inappropriate training model will have a bad impact on the technique being trained. For example, the training model given to the fighters is not varied or is interpreted as a monotonous training method, this has a direct impact on the fighters, for example they are lazy about training and do not experience changes. The aim of this research was to determine the effect of plyometric training on the speed of T kicks in silat martial arts at the 1945 Teachers' Association University, East Nusa Tenggara. In this research, researchers used a one-group pre-test and post-test design with a quantitative experimental method approach. The number of samples in this study was 20 martial artists. Data collection techniques in this research used tests and non-tests. Non-tests include observation, interviews and documentation, then the test method uses two plyomteric training methods. The data analysis technique in this research uses the t-test analysis system. The results of this research prove that based on the results of the calculation of the data in this study, it shows that there is a change in the speed of the T kick in the fighters. With the posttest results, if you look at the pre-test average, it is 21.93 and the post-test value is 23.86%. Based on these results, it was stated that there was an influence of plyometric training, the form of training of which was squat split jump and stride jump crossover, the speed of Pencak Silat T kicks. Based on the categorization of the final test results, the speed of Pencak Silat T kicks performed by the silat fighters was in the Good category.

Abstract

Taekwondo is a Korean martial art characterized by rapid kicks. In the combat category, technical ability is the key to success in gaining points. The aphurigi technique (axe kick) is one of the important techniques in taekwondo because the technique gives a point contribution of around 20% in the match. Thus, it is necessary to investigate kinematic analysis to determine the kinematic parameters that contribute to the success of the aphurigi (axe kick) kick technique. 24 athletes were involved in this research, divided into 2 groups, namely the national level group and the regional group. All samples performed aphurigi kicks, then recorded using a camera and analyzed using skill spector software in 2 dimensions. There are 6 parameters analyzed consisting of kick speed, hip position, angular speed, and kick range. From the measurements that have been carried out, the results show that national-level athletes have significant differences compared to regional athletes in kick speed in the upswing phase, p-0.003, hip position, p-0.045, and knee angle in the upswing phase, p-0.026. However, there were no significant differences in other parameters, including kick speed in the upswing phase, kick range, and knee angle in the upswing phase. The results show the importance of a specific training program to train kinematic parameters that can influence aphurigi kick performance, therefore amateur athletes can master effective kick techniques and compete at the national level.
