Abstract

This study aims to determine the contribution of split squad jump exercises, medicine ball overhead throws, and dumbbell wirst exercises to smash in volleyball female athletes of the noble club in 2020. Statistical testing is assisted by the SPSS statistical program using descriptive tests, prerequisite tests for normality, linearity and tests. correlation and calculate the effective contribution and relative contribution of variables. The research sample was obtained by purposive sampling technique of 10 athletes. Before testing the hypothesis, they must pass the prerequisite test, namely, the normality test is the value > sig. 0.05 and the linearity test is greater than the 5% significance level, the regression correlation test shows that rcount > rtable. R table with the provisions of df = n-2 (10-2 = 8) in the two-way significance test of 0.05 is known to be 0.631. So that each independent variable with its dependent variable is significant. From the results of the prerequisite tests and statistical tests, the data obtained are SE 78.7% and SR 100%. This means that the contribution between the independent and dependent variables in this study is 78.7% while the remaining 21.3% is influenced by other variables outside the study. The results of this study indicate that (1) There is a Contribution of Split Squad Jump to Smash in Volleyball Putri Mulia Medan. (2) There is a Contribution of Medicine Ball Overhead Throw to the Smash in Putri Mulia Volleyball Ball in Medan. (3) There is a Dumbbell Wrist's Contribution to the Smash in the Putri Mulia Volleyball Ball in Medan. (4) There is a contribution of Split Squad Jump, Medicine Ball Overhead Throw and Dumbbell Wrist to Smash on Putri Mulia Volleyball Ball in Medan.Keywords : Split Squad Jump, Medicine Ball Overhead Throw, Dumbbell Wrist, Smash, Volleyball

Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan pengaruh antara latihan downhill running dan uphill running terhadap peningkatan kecepatan lari 100 meter. Metode penelitian yang digunakan adalah eksperimen dengan rancangan two group pretest-posttest design. Sampel penelitian berjumlah 10 atlet yang dibagi menjadi dua kelompok, masing-masing diberi perlakuan latihan downhill running dan uphill running selama 6 minggu. Data diperoleh melalui tes lari 100 meter sebelum dan sesudah latihan, kemudian dianalisis menggunakan uji-t. Hasil penelitian menunjukkan bahwa baik latihan downhill running maupun uphill running memberikan pengaruh yang signifikan terhadap peningkatan kecepatan lari 100 meter (hipotesis 1 dan 2 diterima). Namun, berdasarkan hasil uji-t hipotesis ketiga, diperoleh nilai thitung > ttabel yang berarti terdapat perbedaan yang signifikan antara kedua kelompok latihan. Latihan downhill running memberikan peningkatan kecepatan yang lebih besar dibandingkan uphill running, karena mampu meningkatkan frekuensi langkah dan kecepatan maksimal, sedangkan uphill running lebih berfokus pada penguatan otot tungkai. Kesimpulannya, latihan downhill running lebih efektif dalam meningkatkan kecepatan lari 100 meter dibandingkan uphill running. Hasil penelitian ini dapat dijadikan acuan bagi pelatih dan atlet dalam menentukan metode latihan yang tepat untuk meningkatkan performa sprint.
PERBEDAAN PENGARUH LATIHAN MENGGUNAKAN RAKET TENIS DAN LATIHAN BOUNCE KICK BALL TERHADAP KEMAMPUAN MENERIMA SERVIS PADA ATLET PUTRA SEPAK TAKRAW STC SAMOSIR TAHUN 2023 Firman Putra Jaya Ndraha; Ibrahim Wiyaka

Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan pengaruh latihan menggunakan raket tenis dan latihan bounce kick ball terhadap kemampuan menerima servis atlet putra Sepak Takraw STC Samosir Tahun 2023. Populasi penelitian berjumlah 16 atlet, dengan sampel 10 atlet berusia 14–16 tahun yang dipilih menggunakan teknik matching pairing. Desain penelitian menggunakan pre-test and post-test two group design dengan metode eksperimen. Sampel terlebih dahulu diberikan tes awal, kemudian menjalani program latihan menggunakan raket tenis dan bounce kick ball selama enam minggu, lalu dilakukan tes akhir. Hasil analisis menunjukkan bahwa latihan menggunakan raket tenis memberikan pengaruh signifikan terhadap kemampuan menerima servis (thitung = 11,85 > ttabel = 2,78). Latihan bounce kick ball juga memberikan pengaruh signifikan (thitung = 8,78 > ttabel = 2,78). Selanjutnya, uji perbedaan antar kelompok menunjukkan adanya perbedaan pengaruh antara kedua metode latihan. Persentase peningkatan kemampuan menerima servis pada latihan menggunakan raket tenis sebesar 88,88%, sedangkan latihan bounce kick ball sebesar 72,10%. Dengan demikian, latihan menggunakan raket tenis lebih efektif dengan selisih peningkatan sebesar 16,78% dibandingkan latihan bounce kick ball.

Abstract

This study aims to analyze the kinematics of the overhead serve movement in sepak takraw. The focus of the study includes joint angles, movement speed, and body coordination during the serve. The method used is descriptive quantitative with observation techniques using video recordings analyzed frame by frame. The research subjects consisted of university-level sepak takraw athletes. The results show that the success of the overhead serve is influenced by the coordination between the initial movement, leg swing, and contact with the ball. Optimal angles at the hip, knee, and ankle joints contribute significantly to the speed and accuracy of the serve. Thus, understanding the kinematics aspects can improve the effectiveness of training and athlete performance.
