Abstract

Kelelahan otot lower body secara langsung memengaruhi efisiensi gerakan take off dalam jump spike. Hubungan antara kelelahan dan perubahan kinematika ini menjadi faktor krusial dalam menentukan performa optimal atlet bola voli. Penelitian ini bertujuan untuk menganalisis pengaruh kelelahan otot lower body terhadap kinematika pada fase take off teknik jump spike serta hubungan antara pusat gravitasi tubuh (CG) dan gaya reaksi tanah (GRF). Sampel sebanyak 12 atlet laki-laki Unit Kegiatan Mahasiswa (UKM) Bola Voli Universitas Pendidikan Indonesia (UPI) Bandung. Penelitian ini menggunakan Metode deskriptif dengan pendekatan kuantitatif menggunakan desain pretest dan posttest. Teknik analisis data yang digunakan adalah Uji Paired T Test. Hasil penelitian menunjukkan peningkatan signifikan kadar asam laktat, yang mengindikasikan akumulasi akibat kelelahan. Pada parameter kinematika, tidak ditemukan perbedaan signifikan pada sudut ankle, knee, dan hip, meskipun terjadi perubahan. Namun, jump height menunjukkan penurunan signifikan, menunjukkan bahwa kelelahan mempengaruhi kemampuan lompatan. Selain itu, tidak ditemukan hubungan signifikan antara kelelahan dan perubahan parameter kinematika lainnya. Penelitian ini menyimpulkan bahwa kelelahan otot lower body berdampak signifikan pada performa jump height, namun tidak mempengaruhi sudut tubuh selama fase take off teknik jump spike. Penelitian ini menyarankan pentingnya pengelolaan kelelahan otot untuk menjaga performa jump spike. Pelatih dan atlet harus fokus pada pemulihan dan penguatan lower body. Implikasi penelitian menunjukkan bahwa meskipun sudut tubuh tidak terpengaruh, penurunan jump height dapat mengurangi efektivitas permainan, sehingga latihan daya tahan dan teknik lompatan perlu ditingkatkan. Lower body muscle fatigue directly affects the efficiency of the take-off movement in the jump spike. The relationship between fatigue and kinematic changes is a crucial factor in determining the optimal performance of volleyball athletes. This study aims to analyze the effect of lower body muscle fatigue on kinematics in the take-off phase of the jump spike technique and the relationship between the body's center of gravity (CG) and ground reaction force (GRF). The sample consisted of 12 male Volleyball athletes from the Student Activity Unit (UKM) of the Volleyball Indonesian Education University (UPI) Bandung. This study employed a descriptive method with a quantitative approach using a pretest-posttest design and Paired T-Test for data analysis. The results showed a significant increase in lactic acid levels, indicating accumulation due to fatigue. In the kinematic parameters, no significant differences were found in the ankle, knee, and hip angles, although there were changes. However, jump height showed a significant decrease, indicating that fatigue affects jumping ability. In addition, no significant relationship was found between fatigue and changes in other kinematic parameters. This study concludes that lower body muscle fatigue has a significant impact on jump height performance, but does not affect body angles during the take-off phase of the jump spike technique. This study suggests the importance of managing muscle fatigue to maintain jump spike performance. Coaches and athletes should focus on lower body recovery and strengthening. The implications of the study suggest that even though body angle is not affected, decreased jump height can reduce game effectiveness, so endurance training and jumping technique need to be improved.
