Perlakukan pelaku olahraga menggunkan jenis latihan baru atau metode yang dalam beberapa tahun terakhir populer dalam dunia peningkatan kemampuan fisik, yaitu metode plyometric bervariasi agar atlet tidak merasa jenuh. Jenis latihan plyometric high hurdle jump dan forward and lateral hurdle jump merupakan dua jenis latihan plyometric namun berbeda pelaksanaan. Oleh karena itu, perlunya menyediakan sumber belajar dan sumber daya manusia yang mampu memberikan materi metode latihan plyometric.

Penelitian ini bertujuan untuk mengetahui pengaruh latihan high hurdle jump  dan forward and lateral hurdle jump terhadap peningkatan kekuatan dan power otot tungkai.

Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitian tindakan kelas. Metode penelitian menggunakan metode eksperimen. Desain penelitian menggunakan none equivalent (pretest and post-test) control group design. Variabel bebas dalam penelitian ini adalah latihan high hurdle jump, latihan forward and lateral hurdle jump, dan variabel terikatnya adalah kekuatan dan power otot tungkai. Sampel pada penelitian ini berjumlah 30 siswa kelas X  yang menggunakan teknik random sampling dengan teknik pengelompokan menggunakan ordinal pairing. Analisa data yang digunakan dalam penelitian ini untuk uji pengaruh adalah paired t-test. Selanjutnya untuk uji beda pengaruh antara kelompok perlakuan dan kontrol dilakukan menggunakan one way anova pada sebaran data normal.

Hasil pengujian menunjukkan ada perbedaan yang signifikan pada kelompok eksperimen high hurdle jump terhadap variabel kekuatan dan power otot tungkai dengan nilai signifikansi p sebesar 0.00 < 0.05, kenaikan persentase sebesar 5,82% pada variabel kekuatan dan 3,42% pada variabel power otot tungkai. Ada perbedaan yang signifikan pada kelompok eksperimen forward and lateral hurdle jump terhadap variabel kekuatan dan power otot tungkai dengan nilai signifikansi p sebesar 0.00 < 0.05, kenaikan persentase sebesar 4,51% pada variabel kekuatan dan 3,52% pada variabel power otot tungkai. Latihan high hurdle jump lebih efektif daripada latihan forward and lateral hurdle jump terhadap peningkatan kekuatan dan latihan forward and lateral hurdle jump lebih efektif daripada latihan high hurdle jump terhadap peningkatan power otot tungkai.

Treat sports players using a new type of exercise or a method that has been popular in the world of increasing physical abilities in recent years, namely the varied plyometric method so that athletes don't feel bored. Types of plyometric exercises high hurdle jump and forward and lateral hurdle jump are two types of plyometric exercises but their implementation is different. Therefore, it is necessary to provide learning resources and human resources who are able to provide material for plyometric training methods.

This study aims to determine the effect of high hurdle jump and forward and lateral hurdle jump exercises on increasing leg muscle strength and power.

This research uses a quantitative approach to the type of classroom action research. The research method uses experimental methods. The research design used the none equivalent (pretest and post-test) control group design. The independent variables in this study are high hurdle jump training, forward and lateral hurdle jump exercises, and the dependent variable is leg muscle strength and power. The sample in this study amounted to 30 students of class X who used the random sampling technique. Analysis of the data used in this study to test the effect is paired t-test. Furthermore, to test the difference in effect between the treatment and control groups was carried out using one way ANOVA on the normal data distribution.

The test results showed that there was a significant difference in the high hurdle jump experimental group on the variable leg muscle strength and power with a significance value of p 0.00 <0.05, a percentage increase of 5,82% in the strength variable and 3,42% in the leg muscle power variable. There is a significant difference in the forward and lateral hurdle jump experimental group on the variable leg muscle strength and power with a significance value of p of  0.00 <0.05, a percentage increase of 4,51% in the strength variable and 3,52% in the leg muscle power variable. High hurdle jump exercises are more effective than forward and lateral hurdle jumps to increase strength and forward and lateral hurdle jumps are more effective than high hurdle jumps to increase leg muscle power.
