Abstract

Kafein merupakan suatu zat ergogenik yang biasa dikonsumsi oleh orang awam maupun kalangan atlet untuk meningkatkan performa dalam berolahraga. Kafein terkenal karena efeknya yang dapat meningkatkan ketergugahan, kewaspadaan, dan konsentrasi. Kafein pun juga terbukti efektif dalam meningkatkan daya tahan dalam berolahraga pada cabang olahraga yang membutuhkan daya tahan tinggi atau kombinasi antara daya tahan dan kekuatan. Namun terkait efeknya terhadap cabang olahraga yang membutuhkan akurasi dan waktu reaksi masih jarang terdapat penelitian yang menguji secara empiris. Oleh karena itu tujuan dari penelitian ini adalah untuk mengetahui pengaruh kafein terhadap akurasi dan waktu reaksi pada atlet cabang olahraga yang membutuhkan akurasi dan waktu reaksi. Penelitian ini dilakukan dengan menggunakan metode systematic literature review terhadap 14 artikel yang didapatkan dari 3 sumber portal jurnal. Hasilnya menunjukkan bahwa kafein dapat meningkatkan kecepatan reaksi namun tidak berpengaruh terhadap akurasi pada atlet cabang olahraga. Namun pada dosis yang melebihi batas optimum, kafein dapat mengurangi akurasi dan waktu reaksi pada atlet cabang olahraga.
