A. Latar Belakang Masalah
Olahraga merupakan berbagai aktifitas jasmani yang dilakukan dalam bentuk permainan dan perlombaan dalam rangka memperoleh rekreasi atau kesenangan. Selain itu olahraga dapat menjadi alat pemersatu bangsa, karena tidak ada perbedaan ras dan golongan. Kemudian olahraga juga dapat turut menunjang pembangunan mental dan karakter bangsa yang kuat, lewat filosofi yang lahir darinya. Jenis olahraga apapun itu yaitu fairplay.
Pendidikan jasmani adalah suatu proses pembelajaran melalui aktifitas jasmani yang didesain untuk meningkatkan kebugaran jasmani, mengembangkan ketrampilan motorik, pengetahuan dan perilaku hidup sehat dan aktif, sikap sportif, dan kecerdasan emosi. Lingkungan belajar diatur secara seksama untuk meningkatkan pertumbuhan dan perkembangan seluruh ranah, jasmani, psikomotor, kognitif, dan afektif terhadap siswa.
Salah satu pendidikan jasmani adalah atletik yang diberikan mulai dari sekolah dasar sampai perguruan tinggi. Di sekolah dasar pelajaran pendidikan atletik, termasuk mata pelajaran pendidikan jasmani dan kesehatan adalah lari 60 meter.
Lari adalah aktifitas fisik melakukan gerakan langkah maju dengan kecepatan, sedangkan kecepatan adalah kemampuan seseorang dapat melakukan dengan kaki, gerakan sejenis yang banyak dalam waktu yang singkat.
Pada lari 60 meter , factor pendukung utamanya adalah kecepatan. Oleh karena itu kecepatan dalam melakukan suatu gerak ditentukan oleh berbagai factor. Faktor motoris yang mempengaruhi kecepatan terdiri atas kekuatan, kecepatan reaksi, kontraksi, relaxasi dan koordinasi otot serta explosive power otot tungkai. Selain kecepatan factor pendukung lainya dalam berlari adalah kekuatan otot tungkai yang baik, kemudian diperlukan juga kelincahan dalam gerak dari factor diatas dalam penelitian ini penulis hanya ingin mengetahui kontribusi factor explosive power otot tungkai dengan kecepatan lari, karena explosive power otot tungkai memegang peranan penting dalam kecepatan berlari seseorang.
Sifat motoris yang mempengaruhi kecepatan terdiri atas : kekuatan, reaksi, kontraksi, relaxasi, dan koordinasi otot serta explosive power otot tungkai.
