The effect of water intake on some physiological responses and the concentration of lactic acid in the Anaerobic exercise

Abstract

Abstract This study aimed to identify the effect of water intake on some physiological responses (heart rate at rest, the maximum heart rate during exercise, blood pressure at rest, blood pressure after the exercise). It also aimed to identify the effect of water intake on the concentration of lactic acid in the blood after Anaerobic physical activity. The study sample consisted of 10 students from the Department of Physical Education at the University of Jeddah, average age (20±01 years), body mass index (35 ± 19). The researcher used the experimental method. The researcher used 800 m sprint exercise, then measured heart rate at rest, the maximum heart rate during exercise, Systolic and Diastolic blood pressure at rest and after the exercise, and the concentration of lactic acid before and after the exercise. While the study sample in the second test took an amount of 1liter of water before the exercise. Data were statistically analyzed using the Statistical Package (SPSS) program to get the results using averages, standard deviations, and Kolmogorov-Smirnov Z-test, and t-test for correlated groups. The study results showed the absence of the effect of the intake water before Anaerobic physical exertion on the pulse of the heart at rest, or on the concentration of lactic acid after the effort, while the results showed the effect of the intake water before Anaerobic physical exertion to increase systolic and diastolic blood pressure at rest. The study recommended increasing athletes’ attention to drink eating water before and during physical exercise, and to conduct further scientific studies on the biochemical and physiological variables for both genders for different sports.
