Abstract
The composition of the human body is composed of more than 70 percent in the form of fluids which are divided into organs such as the brain, lungs, kidneys, muscles and bones. Physical activity carried out at moderate intensity results in changes in body temperature causing body effects, one of which is a decrease in endurance. Taekwondo athletes when competing with a duration of 90 seconds result in an increase in body temperature, marked by sweating and dehydration. In these conditions, athletes must restore and maintain body condition to complete a maximum of 3 rounds of competition. The purpose of this study was to determine the effect of giving alkaline and normal fluids on the endurance of male athletes aged 15-17 years. This study used a cross sectional approach with a pre_test, post_test control group design. The sampling technique used purposive sampling. The sample in this study was the male junior Taekwondo kyorugi athlete Purbalingga with a total of 24 athletes. The total administration of liquid pH8 was 1800 ml and pH7 was 1800 ml which was divided into 600 ml 4 hours before exercise, 600 ml during exercise and 600 ml 15 minutes after exercise. Based on the results of the study, the average value of the paired sample t test of the experimental group pH 8 showed that the pre-test treatment was 72.83 and post-test was 76.58. Meanwhile, in the control group, pH 7 showed that the pre-test control was 72.83 and the post-test was 69.92 with a significance value in the treatment group of 0.029 and 0.145 in the control group. The independent value of the treatment group was 0.026 and the control group was 0.027. The treatment group with alkaline water pH 8 had an effect on the endurance of Taekwondo athletes compared to normal pH.
