Abstract

Penelitian ini bertujuan untuk mengetahui: 1) adakah pengaruh latihan Box jump terhadap vertical jump atlet putra Ganevo usia 14-17 tahun, 2) adakah pengaruh latihan standing jump terhadap vertical jump atlet putra Ganevo usia 14-17 tahun, 3) jenis latihan yang lebih efektif terhadap vertical jump atlet putra Ganevo usia 14-17 tahun. Penelitian ini adalah experiment dengan desain penelitian yang digunakan adalah “two groups pretest-posttest design”. Instrumen dalam penelitian ini tes vertical jump dengan reliabilitas 0,99 dan validitas 0,989. Subjek dalam penelitian adalah Atlet Klub Bola Voli Ganevo Usia 14 – 17 Tahun yang berjumlah 24 Atlet. Teknik analisis data menggunakan uji t dengan taraf signifikansi 5 %. Hasil penelitian menyimpulkan: (1) ada pengaruh latihan plyometric box jump terhadap vertical jump atlet bola voli putra Ganevo Usia 14-17 tahun, dengan t hitung (8,660) > t table (2,201), dan nilai Signifikansi (0,000) < dari (0,05), (2) ada pengaruh latihan plyometric standing jump terhadap vertical jump atlet bola voli putra Ganevo Usia 14-17 tahun, dengan t hitung (3,522) > t table (2,201), dan nilai Signifikansi (0,005) < dari (0,05), (3) latihan plyometric standing jump lebih baik untuk meningkatkan vertical jump atlet bola voli Ganevo putra Usia 14-17 tahun, dengan t hitung (2,133) > t table (1,720), dan nilai Signifikansi (0,026) < dari (0,05). Selisih posstest sebesar 1,75 cm.

Abstract

This study aims to determine: 1) is there any influence of Box jump training on vertical jumps of Ganevo male athletes aged 14-17 years, 2) is there any influence of standing jump exercises on vertical jumps of Ganevo male athletes aged 14-17 years, 3) is there any types of exercises give effective effect toward vertical jump of male athlete Ganevo aged 14-17 years. This research is an experiment study using two groups pretest-posttest design. The instrument in this study was a vertical jump test with a reliability of 0.99 and a validity of 0.989. Subjects in this study were Ganevo Volleyball Club Athletes Aged 14-17 Years, 24 Athletes in total as subjects. Data analysis techniques used the t test with a significance level of 5%.The results of the study concluded: (1) there was an effect of plyometric box jump training on the vertical jump of male volleyball athlete Ganevo Age 14-17 years, with t count (8,660)> t table (2,201), and the Significance value (0,000) < of (0 , 05), (2) there is the influence of plyometric standing jump training on the vertical jump of male volleyball athlete Ganevo Age 14-17 years, with t arithmetic (3,522) > t table (2,201), and the Significance value (0.005) < of (0 , 05), (3) plyometric standing jump training is better to increase vertical jump for volleyball athletes of Ganevo men aged 14-17 years, with t arithmetic (2,133)> t table (1,720), and significance value (0.026) <of ( 0.05). Post-test difference of 1.75 cm.
