Abstract

Kemampuan passing bawah merupakan salah satu keterampilan dasar yang harus dikuasai dalam permainan bolavoli. Namun, hasil observasi awal menunjukkan bahwa sebagian besar siswa MTs Miftahul Khaer Mare masih mengalami kesulitan dalam melakukan passing bawah dengan baik dan konsisten. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kemampuan passing bawah siswa melalui metode bola pantul ke lantai dan bola pantul ke dinding. Kegiatan dilaksanakan pada tanggal 25 Juni 2026 dengan melibatkan 30 siswa MTs Miftahul Khaer Mare. Metode pelaksanaan terdiri atas tahap persiapan, pelaksanaan, dan evaluasi. Evaluasi dilakukan menggunakan tes awal (pre-test), tes akhir (post-test), lembar observasi, dan angket kepuasan peserta. Hasil kegiatan menunjukkan bahwa rata-rata nilai kemampuan passing bawah siswa meningkat dari 13,27 pada pre-test menjadi 24,33 pada post-test atau meningkat sebesar 83,35%. Selain itu, hasil angket kepuasan menunjukkan bahwa mayoritas peserta memberikan penilaian baik dan sangat baik terhadap materi pelatihan, metode pembelajaran, kualitas pemateri, dan manfaat kegiatan. Pelatihan passing bawah bolavoli melalui metode bola pantul ke lantai dan bola pantul ke dinding efektif meningkatkan kemampuan passing bawah siswa serta memperoleh respons positif dari peserta.

Abstract

Background: Muscle fiber type composition is a key determinant of physical performance, health, and sports specialization. Training modality whether endurance, resistance, high-intensity interval (HIIT), or plyometric has been shown to induce specific adaptations in Type I (slow-twitch) and Type II (fast-twitch) muscle fibers through distinct molecular and histological pathways. Objectives: This narrative review aims to systematically analyze scientific evidence regarding the influence of various training methods on the dominance of Type I and Type II muscle fibers, covering the underlying mechanisms and implications for sports science practice. Methods: A literature review was conducted using electronic databases including Google Scholar, PubMed, and Scopus, with publication years ranging from 2015 to 2025. Studies involving human subjects with intervention periods of at least 4 weeks and fiber type analysis via muscle biopsy or myosin heavy chain (MHC) isoform identification were included. Results: Endurance training consistently shifts fiber composition toward Type I dominance via PGC-1α/AMPK signaling and mitochondrial biogenesis, while high-load resistance training primarily induces Type II hypertrophy. HIIT and sprint interval training promote Type IIa fiber dominance and hybrid fiber development. Plyometric training selectively enhances Type IIx and IIa recruitment. Detraining reverses these adaptations. Conclusions: Different training methods produce distinct, evidence-based adaptations in muscle fiber type composition. Understanding these shifts is critical for designing sports-specific training programs and optimizing athletic performance.
