Effect of Circulated Flow of Hydrotherapy on Reduction of Lactic Acid Levels in the Body after Physical Exercise

Abstract

The purpose of this study was to analyze the effect of circulating hydrotherapy on reducing lactic acid levels in the body. This study used a 2 x 2 factorial experimental design. Subjects were taken in this study by means of purposive sampling and then the subjects were divided into 4 groups. A total of 24 adult males aged 18-21 years participated in this study. Exclusion criteria in this study were having a history of lung disease and heart disease. Subjects took blood to measure lactic acid levels (Pre-test). Furthermore, the subject carried out the running-based Anaerobic Sprint Test (RAST) activity. Then the subject rested for 2 minutes. Each subject was given an intervention based on their respective groups for 10 minutes. Furthermore, the subject took blood to measure lactic acid levels (post-test). The statistical test used is the two-way Anova in the SPSS application. The results of this study indicate that there are differences in the effect of water temperature of 20 o C, with a water speed of 0.25 and 0.50 liters/second on the decrease in lactic acid levels. There is a significant difference in the effect of water at 37 o C, with a water speed of 0.25 and 0.50 liters/second to reduce lactic acid levels. There is an interaction between water temperature (20 o C, 37 o C) with a water speed of 0.25 and 0.50 liters/second on changes in lactic acid levels. It can be concluded that Circulated Flow of Hydrotherapy with the development of modified Water Temperature (WT), and Water Speed (WS) can both be used to improve recovery by lowering blood lactic acid levels in the body after physical activity.
