The Effect of Green Coconut Water (Cocos Nucifera) before Aerobic Physical Activity on Pulse Recovery in Athletic Athletes

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 5 th , 7 th , and 9 th 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/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 (5 th , 7 th , 9 th 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.
