Pengaruh Pelatihan Knee Tuck Jump dan Double Leg Bound terhadap Power Otot Tungkai

Abstract

Penelitian ini bertujuan untuk mengatahui pengaruh pelatihan knee tuck jump dan double leg bound terhadap peningkatan power otot tungkai. Rancangan penelitian the non-randomized control group pretest posttest design. Subjek penelitian adalah siswa putra peserta ektrakurikuler sepak bola SMA Negeri 2 Singaraja berjumlah 39 orang, hasil pretest dilakukan ordinal pairing, yaitu 13 orang diberikan pelatihan knee tuck jump, 13 orang diberikan pelatihan double leg bound, dan 13 orang kelompok kontrol. Power otot tungkai diukur dengan test vertical jump. Data dianalisis dengan uji F (one way anova) pada taraf signifikansi (α) = 0,05 dengan bantuan program SPSS 16.0. Hasil analisis data pada kelompok perlakuan knee tuck jump terjadi peningkatan power otot tungkai sebesar 58,77, kelompok perlakuan double leg bound sebesar 56,31 dan pada kelompok kontrol sebesar 44,31. Hasil uji one way anova variabel power otot tungkai antara kelompok perlakuan dan kelompok kontrol didapat Fhitung sebesar 8,912 dan signifikasi 0,001 yaitu terjadi perbedaan pengaruh antara pelatihan knee tuck jump dan double leg bound terhadap power otot tungkai. Berdasarkan hasil uji LSD, kelompok pelatihan knee tuck jump lebih baik pengaruhnya dibandingkan pelatihan double leg bound terhadap peningkatan power otot tungkai. disimpulkan; (1) pelatihan knee tuck jump dan double leg bound berpengaruh terhadap peningkatan power otot tungkai. (2) terdapat perbedaan pengaruh antara pelatihan knee tuck jump dan double leg bound terhadap peningkatan power otot tungkai. (3) pelatihan knee tuck jump lebih baik dari pada double leg bound terhadap peningkatan power otot tungkai.

This research to know effect of knee tuck jump and double leg bound to increase leg muscle power. Design with the non-randomized control group pretest posttest design. The subject were 39 male student participants of football extracurricular SMAN 2 Singaraja, then from pretest to get ordinal pairing, 13 male students given knee tuck jump training, 13 male students given training in double leg bound, and 13 male students as control group. Leg muscle power was measured by vertical jump test. Can be analyzed by F test (one way ANOVA) at a significance level (α) = 0.05 with SPSS 16.0. The results of analysis showed a changes in the average value of the leg muscle power variable. In the treatment group of knee tuck jump showed an increase of leg muscle power much as 58,77, group double leg bound much as 56,31 and in the control group much as 44,31. The test results of Fmeasure of one way ANOVA of leg muscle power between the group and the control group was obtained 8,912 and the significance is 0.000, which means there is a difference between the effects of knee tuck jump and double leg bound to the leg muscle power. Based on the test results of LSD, the repetition sprint training group have better influence than knee tuck jump and double leg bound to increase leg muscle power as much as 13.533. From the results of data analysis in the discussion it can be concluded that; (1) training repetition sprint and skipping rope effecting the increase in leg muscle power. (2) There is a difference between the effects of sprint training repetition and skipping rope to increase leg muscle power. (3) The repetition sprint training is better than skipping rope to increase leg muscle power
