Efektivitas Pemberian Minuman Elektrolit Berkarbohidrat Terhadap Kadar Ureum Darah Pada Atlet Dayung Nasional Laki-Laki
Abstract
Latar Belakang: Latihan panjang akan menguras glikogen otot yang dapat diketahui dari peningkatan kadar ureum darah. Hal ini dapat menyebabkan penurunan performa pada latihan atau pertandingan berikutnya. Tujuan: Penelitian ini bertujuan untuk mengetahui efektivitas pemberian minuman elektrolit berkarbohidrat dengan kandungan karbohidrat sebanyak 1 gr/kgBB dibandingkan 0,35 gr/kg BB terhadap penurunan kadar ureum darah. Metode: Penelitian ini merupakan penelitian eksperimental murni, bersifat single blind dengan rancangan silang pada 10 atlet dayung nasional laki-laki di Pelatnas Dayung Pangalengan. Minuman yang diberikan adalah minuman elektrolit dengan jumlah karbohidrat sebanyak 1 gr/kgBB pada kelompok perlakuan dan 0,35 gr/kgBB pada kelompok kontrol. Minuman tersebut diberikan segera setelah latihan dan dua jam berikutnya. Pengambilan sampel darah vena dilakukan untuk mengukur penurunan kadar ureum darah sebelum dan setelah pemberian minuman dengan alat Cobas C111. Hasil: Hasil analisis menunjukkan bahwa penurunan kadar ureum darah lebih tinggi pada kelompok perlakuan yaitu sebesar 7,1% dibandingkan kelompok kontrol hanya sebesar 2,25%. Simpulan: Temuan ini menunjukkan bahwa pemberian minuman elektrolit berkarbohidrat dengan kandungan karbohidrat sebanyak 1 gr/kgBB efektif menurunkan kadar ureum darah.
