Data yang diperoleh selanjutnya di analisis menggunakan regresi ganda. Hasil penelitian berdasarkan perhitungan adalah power otot lengan memberikan sumbangan kecil, power otot togok memberikan sumbangan kecil, Power otot tungkai memberikan sumbangan kecil, power otot lengan, togok dan tungkai secara bersama-sama memberikan sumbangan besar terhadap kemampuan servis atas bolavoli dan sisanya dipengaruhi oleh variabel lain yang tidak masuk dalam penelitian. Dari hasil diatas data disarankan kepada pelatih ekstrakulikuler agar dapat memberikan porsi latihan yang lebih banyak pada power otot lengan supaya siswa mampu bermain bolavoli serta melakukan servis atas dengan baik karena didukung power otot lengan yang kuat, menekankan kepada siswa bahwa untuk melakukan servis atas dengan baik harus didukung juga dengan power otot togok yang sehat. siswa harus menjaga kesehatan otot togok agar berfungsi secara maksimal yaitu sebagai penyeimbang gerakan tubuh, bagi siswa yang mengikuti kegiatan ekstrakulikuler bolavoli tidak hanya menjadikan bolavoli sebagai kegiatan pengisi waktu luang, tetapi akan lebih baik jika siswa bisa terus memaksimalkan kemampuan dalam bermain bolavoli sehingga akan terlahir atlet bolavoli yang handal dari siswa ekstrakulikuler bolavoli SMA Negeri 1 Mranggen Kabupaten Demak. This research is to find out how much influence of arm power, torso power, and leg power to the ability of volleyball top service.
