    Abstract
    Ecxercise is defined as any body movement produced by skeletal muscle thats results in energy expenditure that is planned and repetitive with a goal of improving physical ftiness. During exercise, the cardiovascular and respiratory responses are characterised by increase in heart rate, cardiac output and oxygen consumption. This condition , heart rate, CO and O2 consumption increase linearly with intensity oh exercise. The breathing of supplemental oxygen has been used as a potential ergogenic aid. The consumption of water that is purported to contain 7-10 times the normal amount of oxygen (oxygenated water) that it can enhance both exercise performance and recovery between bouts of exercise. The purpose of this study to identification from the different heart rate for along to during exercise given to drinking oxygenated water with placebo. The junior high school with the Body Mass Index (BMI) between 16 – 20 (n=40) selected with simple random had taken oxygenated water and 400 cc plan water. All the children given oxygenated water and plain water 30 minutes before the exercise for along 10 minutes. The heart rate was measure when exercise, resting and recovery time. From this study we found undifferent significant statisticly between heart rate from two goup to given drinking oxygenated water and placebo when the resting, peak during exercise and the recovery.
     
    Latihan fisik / olah raga adalah pergerakan tubuh yang dilakukan oleh otot dengan terencana dan berulang yang menyebabkan peningkatan pemakaian energi untuk memperbaiki kebugaran fisik. Denyut jantung, curah jantung dan kebutuhan oksigen meningkat pada saat melakukan latihan fisik. Keadaan ini meningkat secara linier terhadap intensitas latihan fisik tersebut. Salah satu upaya untuk meningkatkan kadar oksigen yang masuk ke dalam tubuh adalah dengan air minuman beroksigen yang memiliki potensial dalam pengiriman oksigen sehingga dapat memperbaiki performans latihan fisik . Penelitian ini dilakukan untuk mengetahui perbedaan denyut jantung selama latihan fisik terhadap pemberian minuman beroksigen dengan plasebo . Anak Sekolah Lanjutan Tingkat Pertama (SLTP) dengan BMI antara 16 – 20 (n=40) yang telah diacak secara sederhana untuk mendapatkan air beroksigen dan plasebo sebanyak 400 cc. Air beroksigen atau plasebo diminum 30 menit sebelum latihan fisik, dengan lama latihan 10 menit. Denyut jantung diukur pada saat istirahat, puncak latihan fisik dan masa pemulihan. Pada penelitian ini kami tidak ada menemukan perbedaan bermakna secara statistik terhadap denyut jantung pada saat istirahat, puncak latihan fisik dan masa pemulihan pada kedua kelompok baik kelompok yang mendapat air beroksigen atau plasebo.
