Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh program latihan power otot tungkai dan power otot lengan yang dilakukan di air dan di darat terhadap kemampuan renang gaya bebas 50 meter pada peserta didik Swimming Club Guru Renang Lampung (GRL). Penelitian ini menggunakan metode eksperimen semu dengan desain two groups pretest–posttest. Sampel penelitian berjumlah 22 peserta didik yang dibagi menjadi dua kelompok, yaitu kelompok latihan di air dan kelompok latihan di darat. Instrumen penelitian berupa tes kecepatan renang gaya bebas 50 meter dengan satuan waktu detik. Analisis data dilakukan menggunakan uji normalitas, uji homogenitas, serta uji hipotesis menggunakan paired sample t-test dan independent sample t-test pada taraf signifikansi 0,05. Hasil uji paired sample t-test menunjukkan bahwa latihan di air memberikan pengaruh yang signifikan (t = 8,696; p < 0,05), dan latihan di darat juga memberikan pengaruh yang signifikan terhadap kemampuan renang gaya bebas 50 meter (t = 6,185; p < 0,05). Selanjutnya, hasil uji independent sample t-test menunjukkan bahwa tidak terdapat perbedaan pengaruh yang signifikan antara kelompok latihan di darat dan kelompok latihan di air (t = 0,278; p > 0,05). Dengan demikian, latihan power otot tungkai dan power otot lengan baik di air maupun di darat sama-sama efektif dalam meningkatkan kemampuan renang gaya bebas 50 meter.

Abstract

This study aimed to analyze the contribution of leg speed, arm reaction speed, leg power, and arm power to the speed of the Gyaku Tsuki punching technique in female athletes at Jagabaya Raharja Dojo. The research employed a descriptive method with a correlational approach. The sample consisted of 20 female athletes selected using a total sampling technique. The research instruments included tests of leg speed, arm reaction speed, leg power, arm power, and Gyaku Tsuki punching speed. Data analysis was conducted using Pearson Product Moment correlation to examine partial relationships, as well as multiple correlation with the F-test to analyze simultaneous relationships at a significance level of 0.05. The results showed that leg speed had a significant relationship with the speed of the Gyaku Tsuki punch (r = 0.749). Arm reaction speed demonstrated a very strong and significant relationship (r = 0.896). Leg power also showed a significant relationship (r = 0.609), while arm power had a strong and significant relationship (r = 0.722). Simultaneously, leg speed, arm reaction speed, leg power, and arm power were significantly related to the speed of the Gyaku Tsuki technique, with a multiple correlation value of R = 0.933 and a contribution of 87%. These findings indicate that all research hypotheses were accepted, and these biomotor components should be developed in an integrated manner to improve the speed of the Gyaku Tsuki technique in karate athletes.

Abstract

This study aimed to analyze the relationship between arm muscle strength, hip muscle strength, and leg muscle power with the speed of Seoi Nage throwing performance among male athletes aged 16–20 years at the Seishin Judoka Club training center. The research applied a quantitative approach using a correlational method. The sample consisted of 20 athletes selected through a total sampling technique. The instruments included arm muscle strength tests, hip muscle strength tests, leg muscle power tests, and a Seoi Nage throwing speed test. The data were analyzed using Pearson Product Moment correlation and multiple regression analysis with the assistance of SPSS at a significance level of 0.05. The results indicated that (1) there was a significant relationship between arm muscle strength and Seoi Nage throwing speed (r = 0.601 > r-table = 0.444), (2) hip muscle strength also showed a significant relationship (r = 0.640 > r-table = 0.444), and (3) leg muscle power had a significant relationship with throwing speed (r = 0.700 > r-table = 0.444). Simultaneously, the three variables showed a significant relationship with Fcount = 7.401 > Ftable = 3.239 and contributed 58.1%. In conclusion, arm muscle strength, hip muscle strength, and leg muscle power play an important role in improving the speed of Seoi Nage throwing performance in judo athletes.
