PENGARUH PELATIHAN SPLIT JUMP DAN SKIPPING TERHADAP DAYA LEDAK OTOT TUNGKAI PADA SISWA PUTRA PESERTA EKSTRAKURIKULER BULUTANGKIS SMP NEGERI 1 SERIRIT TAHUN 2014

Abstract

Penelitian ini bertujuan untuk mengetahui (1) pengaruh pelatihan split jump terhadap daya ledak otot tungkai, (2) pengaruh pelatihan skipping terhadap daya ledak otot tungkai, (3) perbedaan pengaruh antara pelatihan split jump dan skipping terhadap daya ledak otot tungkai. Subjek penelitian adalah siswa putra peserta ekstrakurikuler bulutangkis SMP Negeri 1 Seririt tahun 2014 yang berjumlah 30 orang. Penelitian ini menggunakan metode eksperimen dengan rancangan the modified group pre-tes post-test design. Tes pengumpulan data menggunakan tes vertical jump. Analisis data menggunakan perhitungan dengan uji anava satu jalur taraf signifikansi α = 0,05 bantuan program SPSS 16,0. Data hasil penelitian ini diuji menggunakan Uji Least Significant Difference (LSD), dengan hasil (1) pelatihan split jump berpengaruh terhadap peningkatan daya ledak otot tungkai dengan hasil rata-rata pre-test 47,47 dan rata-rata post-test 49,93, sehingga didapatkan rata-rata gain-score 2,47, (2) pelatihan skipping berpengaruh terhadap peningkatan daya ledak otot tungkai dengan hasil rata-rata pre-test 46,93 dan rata-rata post-test 50,60, sehingga didapatkan rata-rata gain-score 3,67, (3) pelatihan skipping memberikan pengaruh lebih baik dari pada pelatihan split jump terhadap peningkatan daya ledak otot tungkai dengan mean difference 1,200. Disimpulkan bahwa (1) Ada pengaruh pelatihan split jump terhadap peningkatan daya ledak otot tungkai, (2) Ada pengaruh pelatihan skipping terhadap peningkatan daya ledak otot tungkai, (3) Ada perbedaan pengaruh antara pelatihan split jump dan skipping terhadap peningkatan daya ledak otot tungkai, dimana pengaruh pelatihan skipping lebih baik dari pada pelatihan split jump terhadap peningkatan daya ledak otot tungkai.
Kata Kunci : split jump, skipping, daya ledak, otot tungkai.

This study aims to determine (1) the effect of the split jump training on explosive power leg muscle , (2) the effect of skipping training on leg muscle explosive power , (3) the difference between the effect of the split jump and skipping training on explosive power leg muscle . The subjects were male student extracurricular participants badminton SMP Negeri 1 Seririt 2014 , amounting to 30 people . This study used an experimental method to the design of the modified group pre - test post - test design . Test data collection using vertical jump test . Data analysis using ANOVA test calculations with one lane significance level α = 0.05 SPSS 16.0. Data were tested using the Least Significant Difference test ( LSD ) , with the result (1) training split jump affect the increase in leg muscle explosive power with the average results of pre-test average of 47.47 and a post-test 49.93 , so we get an average gain -score of 2.47 , (2) training skipping effect on the increase in leg muscle explosive power with the average results of pre-test average of 46.93 and a post-test 50.60 , so we get the average -rata gain -score of 3.67 , (3) training skipping give better effect than the split jump training to increase the explosive power of the leg muscles with a mean difference of 1,200 . It was concluded that (1) There is an effect of split jump training to increase leg muscle explosive power , (2) There is the effect of skipping training to increase leg muscle explosive power , (3) There is a difference between the effect of the split jump and skipping training to increase explosive power leg muscle , where the effect of skipping training is better than the split jump training to increase explosive power leg muscle.
