Power otot tungkai bawah merupakan salah satu komponen penting dalam
menunjang performa atlet sepak bola, terutama dalam aktivitas seperti
menendang, berlari cepat, dan perubahan arah secara mendadak. Meskipun
banyak pemain telah menguasai teknik dasar permainan, tetapi belum tentu
memiliki power otot yang optimal. Salah satu bentuk latihan yang terbukti efektif
dalam meningkatkan kekuatan dan daya ledak otot tungkai adalah Plyometric
Barrier Hops (PBH) dan Zig-Zag. Penelitian ini bertujuan untuk mengetahui
pengaruh latihan PBH dan Zig-Zag terhadap peningkatan power otot tungkai
bawah pada pemain sepak bola Amri FC di Nagari Batu Taba tahun 2025.
Penelitian ini menggunakan desain quasi eksperimen dengan rancangan one group
pretest-posttest. Sampel dalam penelitian ini berjumlah 11 orang pemain sepak
bola berusia 1618 tahun yang dipilih secara purposive sampling. Intervensi
dilakukan selama 4 minggu dengan frekuensi tiga kali latihan per minggu.
Instrumen pengukuran yang digunakan adalah vertical jump test. Hasil penelitian
menunjukkan peningkatan rata-rata power otot tungkai dari 32,00 cm sebelum
intervensi menjadi 36,00 cm setelah intervensi. Hasil uji Wilcoxon menunjukkan
nilai signifikansi sebesar p=0,003 (p

Lower limb muscle power is one of the key components in supporting the
performance of football athletes, especially in activities such as kicking, sprinting,
and sudden changes in direction. Although many players may have mastered the
basic techniques of the game, they do not necessarily possess optimal muscular
power. One form of training that has been proven effective in enhancing lower
limb strength and explosiveness is Plyometric Barrier Hops (PBH) and Zig-Zag
drills. This study aimed to determine the effect of PBH and Zig-Zag training on
increasing lower limb muscle power in Amri FC football players in Nagari Batu
Taba in 2025. This research used a quasi-experimental design with a one-group
pretest-posttest approach. The sample consisted of 11 football players aged 1618
years, selected through purposive sampling. The intervention lasted for four
weeks, with a training frequency of three sessions per week. The measurement
instrument used was the vertical jump test. The results showed an increase in the
average lower limb power from 32.00 cm before the intervention to 36.00 cm after
the intervention. The Wilcoxon test revealed a significance value of p = 0.003 (p <
0.05), indicating that PBH and Zig-Zag training had a statistically significant
effect on lower limb power. In conclusion, plyometric barrier hops and zig-zag
drills can significantly improve lower limb muscle power. This type of training
can serve as an effective alternative method in physical training programs to
support the performance of football players.
