Kata Kunci: Bentuk dan Program Latihan Plyometric, Power, Kekuatan Otot Tungkai

Penelitian ini bertujuan untuk mengkaji tentang: (1) Efektivitas Latihan Plyometric Knee Tuck Jump Menggunakan Landasan Pasir Pantai Terhadap Power dan Kekuatan Otot Tungkai, (2) Efektivitas Latihan Plyometric Hurdle Jump Menggunakan Landasan Pasir Pantai Terhadap Power dan Kekuatan Otot Tungkai, (3) Menganalisis pengaruh bentuk latihan dan program latihan plyometric Knee Tuck Jump dan Hurdle Jump, yang paling efektif memberikan efektivitas terhadap peningkatan power otot tungkai. (4) Menganalisis pengaruh bentuk latihan dan program latihan plyometric Knee Tuck Jump dan Hurdle Jump, yang paling efektif memberikan efektivitas terhadap peningkatan kekuatan otot tungkai. Sampel penelitian adalah Mahasiswa Pendidikan Kepelatihan Olahraga yang memilih kepelatihan cabang olaharaga sepakbola sebanyak 33 Mahasiswa yang dibagi dalam tiga kelompok dengan masing-masing kelompok berjumlah 11 Mahasiswa.  Kelompok eksperimen I mendapat perlakuan latihan knee tuck jump, Kelompok eksperimen II mendapat perlakuan latihan hurdle jump dan Kelompok III yaitu kelompok kontrol (konvensional) tidak mendapatkan perlakuan. Penelitian ini dilakukan selama 5 minggu. Jenis penelitian ini menggunakan penelitian kuantitatif dengan metode quasi experiment. Rancangan penelitian menggunakan Non-Randomize Pre Test Post Test Control Group Design, serta analisis data menggunakan ANOVA. Proses pengambilan data dilakukan dengan Force Decks FDLITE untuk power otot tungkai dan Nordbord untuk kekuatan otot tungkai, pada saat pretest dan posttest. Kemudian data dianalisis SPSS 23.0. Data Kelompok I Knee Tuck Jump antara lain: power otot tungkai mengalami peningkatan 12.62%, kekuatan otot tungkai mengalami peningkatan 13.36 %, Kelompok II Hurdle Jump antara lain: power otot tungkai mengalami peningkatan 14.83 %, kekuatan otot tungkai mengalami peningkatan 16.63%. Hasil di atas dapat disimpulkan; (1) Terdapat efektivitas latihan plyometric knee tuck jump terhadap power otot tungkai dan kekuatan otot tungkai; (2) Terdapat efektivitas latihan plyometric hurdle jump terhadap power otot tungkai dan kekuatan otot tungkai; (3) Terdapat perbedaan efektifitas bentuk latihan dan program latihan plyometric knee tuck jump dan hurdle jump terhadap power otot tungkai; (4) Terdapat perbedaan efektifitas bentuk latihan dan program latihan plyometric knee tuck jump dan hurdle jump terhadap kekuatan otot tungkai.

Key words: Plyometric Exercise Forms and Programs, Power, Leg Muscle Strength

            This study aims to examine about: (1) The Effectiveness of Plyometric Knee Tuck Jump Training Using Beach Sand Platform on Leg Muscle Power and Strength, (2) The Effectiveness of Plyometric Hurdle Jump Training Using Beach Sand Platform on Leg Muscle Power and Strength, (3) Analyzing the effect of exercise forms and plyometric Knee Tuck Jump and Hurdle Jump exercise programs, which most effectively provide effectiveness on increasing leg muscle power. (4) Analyze the effect of exercise forms and plyometric exercise programs Knee Tuck Jump and Hurdle Jump, which most effectively provide effectiveness on increasing leg muscle strength. The research sample was Sports Coaching Education Students who chose to coach football sports as many as 33 students divided into three groups with each group totaling 11 students.  Experimental group I received knee tuck jump exercise, experimental group II received hurdle jump training treatment and Group III, the control group (conventional) did not get treatment. The study was conducted for 5 weeks. This type of research uses quantitative research with quasi-experimental methods. The research design used Non-Randomize Pre Test Post Test Control Group Design, as well as data analysis using ANOVA. The data collection process was carried out with FDLITE Force Decks for leg muscle power and Nordbord for leg muscle strength, during pretest and posttest. Then the data was analyzed SPSS 23.0. Group I Knee Tuck Jump data includes: leg muscle power increased by 12.62%, leg muscle strength increased by 13.36%, Group II Hurdle Jump included: leg muscle power increased by 14.83%, leg muscle strength increased by 16.63%. The above results can be concluded; (1) There is an effectiveness of plyometric knee tuck jump exercises on leg muscle power and leg muscle strength; (2) There is an effectiveness of plyometric hurdle jump exercises on leg muscle power and leg muscle strength; (3) There are differences in the effectiveness of plyometric knee tuck jump and hurdle jump exercise forms and programs on leg muscle power; (4) There are differences in the effectiveness of plyometric knee tuck jump and hurdle jump exercise forms and programs on leg muscle strength.
