Abstract: Athletics is a sport with many numbers of matches, every athlete can take 2 numbers, this requires a nutrient that can help restore the pulse faster, especially in running numbers. The objective of this study is to determine the effect of green coconut water on the decrease in recovery pulse at the 5th, 7th, and 9th minute. The research method used in this study is pre-experimental design with one-group pretest-posttest design. The population of the study was athletes in Pekalongan Regency with 13 total sample. Materials / research tools used are whistles, measuring cups, pencils, notebooks, green coconut water. The study was conducted in February 2020 at Widya Manggala Krida Stadium, Pekalongan Regency. This study uses two research variables: (1) independent variables: mineral water and green coconut water (2) dependent variables: recovery pulse (5th, 7th, 9th minutes). The research data analysis technique was independent t-sample test. The test was carried out at a significant level of p = 0.05. Statistical test results from the t-sample show that there is a difference in recovery pulse at the 5th minute (p = 0.002), recovery pulse at the 7th minute (p = 0,000), recovery pulse at the 9th minute (p = 0.001 ). The conclusion in this study is that there is an effect of giving green coconut water drink before aerobic physical activity on the recovery pulse. Keywords: mineral water, green coconut water, aerobic physical activity, recovery pulse AbstrakAtletik merupakan cabang olahraga dengan banyak nomor pertandingan, setiap atlet dapat mengikuti 2 nomor pertandingan, hal ini dibutuhkan suatu nutrisi yang dapat membantu memulihkan denyut nadi lebih cepat terutama dinomor lari. Penelitian ini bertujuan mengetahui pengaruh air kelapa hijau terhadap pemulihan denyut nadi dimenit lima, tujuh dan sembilan. Metode penelitian menggunakan pre Experimental Design melalui One Group Pretest - Posttest Design. Populasi menggunakan atlet atletik Kabupaten Pekalongan dengan jumlah sampel 13. Bahan/alat penelitian yang digunakan adalah peluit, gelas ukur, pensil, buku catatan dan air kelapa hijau. Penelitian ini dilakukan pada bulan Februari 2020 di Stadiun Widya Manggala Krida Kedungwuni Kabupaten Pekalongan. Variabel Penelitian: 1) Variabel bebas terdiri dari air mineral dan air kelapa hijau (cocos nucifera), 2) Variabel terikat menggunakan pemulihan denyut nadi pada menit kelima, ketujuh dan kesembilan. Analisis data menggunakan t-sample independent dengan taraf signifikan p=0,05. Uji statistik t-sample memperlihatkan adanya perbedaan pemulihan denyut nadi dimenit lima p=0,002., menit ketujuh p=0,000., dan menit kesembilan p=0,001. Simpulan penelitian ini menunjukkan adanya pengaruh pemberian air kelapa hijau sebelum melakukan aktifitas fisik aerobik terhadap pemulihan denyut nadi.Kata kunci: air mineral, air kelapa hijau, aktivitas fisik aerobik, pemulihan denyut nadi
Keywords: Cocos Nucifera / denyut nadi pada / atlet atletik / pengaruh air kelapa hijau / Terhadap Pemulihan Denyut Nadi
