Daftar Isi:
- Muscle power was defined as the combination between speed and strenght of muscle contraction and enters in the fitness components. Plyometrics exercises can be used to improve the skills of volleyball players. This study was an experimental study using research designs pre test and post test control group design. The sampling technique inthis study with a simple random sampling. The total sample of 20 person so in one group consisted of 10 person. The first group was given additional ballistic stretching on knee tuck jump exercise. The second group was given knee tuck jump exercise. Measurements of leg muscle power using vertical jump test. Normality test p > 0.05 and homogeneitytest p > 0.05. The results showed an increase in leg muscle power in first group amounted to 14.30 cm and in second group an increase of 7.70 cm. Paired samples t-test p value = 0.000 (p <0.05) in first group and p = 0.000 (p < 0.05) in second group. Test increase explosive power leg muscle after exercise in both groups using independent sample t-test obtained first group and second group where p = 0.000 (p <0.05) with an increase in the percentage of 30.95% in the first group and 16.73% in the second group. From the research done can be concluded that the addition of ballisticstretching on knee tuck jump exercise is more effective than knee tuck jump exercise in increasing explosive power leg muscle in male volleyball players Medical Faculty Of Udayana University. Keywords: muscle power, ballistic stretching, knee tuck jump, vertical jump test.
- Daya ledak otot didefinisikan sebagai kombinasi antara kecepatan dan kekuatan kontraksi otot serta masuk didalam komponen kebugaran. Latihan pliometrik dapat digunakan untuk memperbaiki kemampuan para pemain voli. Penelitian ini merupakan penelitian eksperimental dengan menggunakan rancangan penelitian Pre Test and Post TestControl Group Design. Teknik pengambilan sampel dalam penelitian ini dengan simple random sampling. Jumlah sampel sebanyak 20 orang sehingga dalam dalam satu kelompok terdiri dari 10 orang. Kelompok pertama diberikan penambahan ballistic stretching pada latihan knee tuck jump. Kelompok kedua diberikan pelatihan knee tuck jump. Pengukuran daya ledak otot tungkai menggunakan vertical jump test. Uji normalitas p > 0,05 serta uji homogenitas p >0,05. Hasil penelitian menunjukkan adanya peningkatan daya ledak otot tungkai pada kelompok 1 sebesar 14,30 cm dan pada kelompok 2 terjadi peningkatan sebesar 7,70 cm. Uji paired sample t-test didapatkan nilai p = 0,000 (p < 0,05) pada kelompok 1 dan nilai p = 0,000 (p < 0,05) pada kelompok 2. Uji peningkatan daya ledak otot tungkai sesudah latihan pada kedua kelompok menggunakan independent sample t-test didapat kelompok 1 dan kelompok 2 dimana p = 0,000 (p < 0,05) dengan peningkatan dalam persentase sebesar 30,95 % pada kelompok pertama dan 16,73 % pada kelompok kedua. Dari penelitian yang dilakukan tersebut dapat diperoleh simpulan penambahan ballistic stretchingpada latihan knee tuck jump lebih efektif daripada latihan knee tuck jump dalam meningkatkan daya ledak otot tungkai pada pemain voli laki-laki Fakultas Kedokteran Universitas Udayana. Kata kunci : Daya ledak otot, ballistic stretching, knee tuck jump, vertical jump test.
