dc.description.abstractIngestion beverage of carbohydrate electrolyte during exercise can assist to mount the achievement by slowing fatigue. Fatigue of because decreasing deposit of source of glycogen and indefensible reproduced ATP result the improvement of IMP and ammonia of during fatigue. The aim this research the change of plasma ammonia and urea of before, during and after exercise, after ingestion beverage of carbohydrate - electrolyte. Ten male subjects (age 18-30 years) were subjected to cycle ergometer at 60% of maximal O2 consumption (VO2max) with a pedal speed of 60 rpm until they become fatigued. They were given d drink of carbohydrate-electrolyte at a concentration of 6%, 12% and a flavored water placebo (W) to consume at a volume of 3 ml/kg bw every 20 minutes. Blood samples were taken at rest and during at every 20 minutes for analyzing plasma ammonia and urea. Mean exercise until the on set of fatigue in subjects this research is discovered that no difference for given three beverages. However, plasma ammonia and urea was to be significantly increase compared before and after exercise. Thereby that increase of plasma ammonia of during fatigue, and can become an criteria of increase ammonia with intensity exercise until fatigue. Possibility seems better than the increase of acid lactate.en_US
dc.description.abstractPemberian minuman karbohidrat berelektrolit dapat membantu proses memperlambat terjadinya kelelahan selama berolahraga. Kelelahan disebabkan karena berkurangnya sumber glikogen yang tidak dapat mempertahankan resistensi ATP sehingga menyebabkan peningkatan inosin monofosfat (IMP) serta amonia selama berolahraga. Tujuan penelitian ini untuk mengetahui perubahan plasma amonia dan urea sebelum, selama latihan, sampai terjadi kelelahan setelah pemberian minuman karbohidrat berelektrolit atau tidak berkarbohidrat. Penelitian ini melibatkan 10 naracoba laki-laki berumur 18-30 tahun, dengan mengayuh sepeda ergometer diberi beban VO2max 60% dengan kecepatan 60 rpm sampai terjadi kelelahan. Setiap naracoba diberi minuman karbohidrat berelelektrolit dengan konsentrasi 12%, 6% dan placebo volumenya 3ml/kg/bb setiap 20 menit, dalam waktu yang sama diambil darah sebanyak 5 ml untuk pemeriksaan plasma amonia dan urea. Hasil penelitian menunjukan bahwa plasma amonia dan urea bagi ketiga minuman ini tidak ada perbedaan, akan tetapi bila dibandingkan sebelum dengan selama latihan terdapat peningkatan yang signifikan. Disimpulkan bahwa dengan peningkatan plasma amonia selama latihan dapat menjadi indikator untuk intensitas latihan, jadi jelaslah bahwa untuk kriteria intensitas latihan sampai lelah penentuan hasilnya lebih baik daripada plasma laktat.en_US
