[ABSTRAK
Pasca latihan yang berat dan lama, atlet memerlukan suplemen gizi yangtepat untuk memaksimalkan pemulihan dan performa. Penelitian ini bertujuanuntuk membuktikan pengaruh susu cokelat dan minuman berkarbohidrat-proteinterhadap pemulihan dan performa atlet dayung nasional cabang rowing puteraberusia 18 – 23 tahun. Penelitian ini merupakan penelitian eksperimental murniyang bersifat single-blind dengan crossover design dan dilaksanakan di PelatnasDayung Pengalengan, Jawa Barat pada Bulan April 2015. Atlet diberikan susucokelat atau minuman berkarbohidrat-protein selama 4 jam recovery di antara 2latihan endurance. Sebelum (pre) dan sesudah latihan (post), sampel darah venadiambil untuk mengukur peningkatan ureum darah dan kreatin kinase darahsebagai indikator pemulihan, masing-masing menggunakan Cobas C111 danAdvia 1650/1800. Performa diukur pada latihan ke-2 menggunakan ergometerdayung. Peningkatan ureum darah, kreatin kinase darah dan performa antarakedua perlakuan dibandingkan menggunakan uji t independen. Hasil analisismembuktikan bahwa peningkatan rata-rata ureum darah setelah pemberian susucokelat lebih rendah, yakni 9,14 ± 3,39 mg/dl dibandingkan minumanberkarbohidrat-protein, yakni 16,29 ± 4,89 mg/dl (p value = 0,012) yang artinyapemulihan glikogen otot setelah pemberian susu cokelat lebih tinggi dibandingkanminuman berkarbohidrat-protein. Hal ini menunjukkan bahwa susu cokelatmerupakan alternatif suplemen pasca latihan yang efektif.

ABSTRACT
After an intense and long lasting exercise, athletes have sought nutritionalsupplements to maximize recovery and performance. This study compared theeffects of chocolate milk and carbohydrate-protein replacement drink on recoveryand performance among national rowing male athletes aged 18 – 23 years. This isa single-blind, true experimental study with crossover design, conducted inNational Training Centre, Pengalengan, April 2015. Athletes received milkchocolate or carbohydrate-protein replacement drink during 4 hours recoverybetween 2 endurance exercises. Before (pre) and after exercise (post), venousblood sample was collected to measure the increase of blood urea nitrogen (BUN)and creatin kinase (CK) as indicator of recovery, using Cobas C111 and Advia1650/1800 respectively. Performance was measured in the second exercise usingrowing ergometer. The effects of each treatment on BUN, CK and performancewas compared by using independent t tests. The result demonstrated that theincrease of BUN were significantly lower (muscle glycogen recovery weresignificantly higher) for chocolate milk trial compared to carbohydrate-proteinrepleacement drink trial (9,14 ± 3,39 mg/dl vs. 16,29 ± 4,89 mg/dl, P = 0,012). Itsuggested that chocolate milk is an effective post-workout recovery aid., After an intense and long lasting exercise, athletes have sought nutritionalsupplements to maximize recovery and performance.
