Kata-kata Kunci: hydroterapy, suhu, sirkulasi air, asam laktat

Kelelahan merupakan kondisi yang dialami atlet pasca latihan atau pertandingan. Kelelahan disebabkan kandungan asam laktat yang berlebihan dalam sel tubuh. Hal ini dapat menganggu performa atlet dalam latihan atau pertandingan selanjutnya. Penelitian ini bertujuan untuk mengetahui pengaruh circulated flow of hydrotherapy terhadap penurunan kadar asam laktat Pasca Latihan.

Penelitian ini bertujuan untuk mengetahui: (1) pengaruh antara suhu air 20^oC, dan 37 ^oC terhadap penurunan kadar asam laktat, (2) perbedaan pengaruh antara kecepatan air 0,25 ,dan 0,50 liter/detik terhadap penurunan kadar asam laktat, (3)pengaruh interaksi antara suhu air dan kecepatan air terhadap perubahan kadar asam laktat. Penelitian dilakukan dengan metode eksperimen factorial 2x2 menggunakan 6 kelompok subyek uji dengan kondisi biometrik yang relatif sama. Perlakuan hydrotherapy diberikan dengan penambahan sirkulasi aliran air yang memiliki efek pijat di permukaan tubuh. Temperatur air divariasikan sebesar 20 ^oC dan 37^oC. Kecepatan  air divariasikan sebesar 0.25 dan 0.50 liter/detik. 

Hasil penelitian ini menunjukkan bahwa: (1) ada perbedaan pengaruh yang signifikan suhu air 20^oC, dengan kecepatan air 0,25, dan 0,50 liter/detik terhadap penurunan kadar asam laktat, terbukti dari (K1), (K2) nilai p=0.002<0.05,(2) ada perbedaan pengaruh yang signifikan suhu air 37^oC, dengan kecepatan air 0,25, dan 0,50 liter/detik terhadap penurunan kadar asam laktat, terbukti dari (K2), (K3) nilai p=0.002<0, (3) ada interaksi antara suhu air (20^oC, 37^oC) dan kecepatan air 0,25, dan 0,50 liter/detik terhadap perubahan kadar asam laktat, terbukti dari nilai p=0.04 <0.05. Kelompok yang mempunya hasil maksimal dalam menurunkan kadar asam laktat Pasca Latihan yaitu variasi (K4), (K3), (K1), dan (K2).

Key Words: hydrotherapy, temperature, water circulation, lactic acid
Fatigue is a condition experienced by athletes after training or competition. Fatigue is caused by excessive lactic acid content in the body's cells. This can interfere with the athlete's performance in training or the next match. This study aims to determine the effect of circulated flow of hydrotherapy on decreasing post-exercise lactic acid levels.
This study aims to determine: (1) the effect of water temperature of 20oC and 37oC on decreasing lactic acid levels, (2) the difference in effect between water speeds of 0.25 and 0.50 liters/second on decreasing lactic acid levels, ( 3) the effect of the interaction between water temperature and water speed on changes in lactic acid levels. The research was conducted using the 2x2 factorial experiment method using 6 groups of test subjects with relatively the same biometric conditions. Hydrotherapy treatment is given by adding circulating water flow which has a massage effect on the surface of the body. The water temperature was varied by 20oC and 37oC. The speed of the water is varied by 0.25 and 0.50 liter/second.
The results of this study indicate that: (1) there is a significant difference in the effect of water temperature of 20oC, with a water speed of 0.25 and 0.50 liters/second on the decrease in lactic acid levels, as evidenced by (K1), (K2) p = 0.002 <0.05, (2) there is a significant difference in the effect of water temperature of 37oC, with a water speed of 0.25 and 0.50 liter/second on the decrease in lactic acid levels, as evidenced by (K2), (K3) p value = 0.002 < 0, (3) there is an interaction between water temperature (20oC, 37oC) and water speed of 0.25 and 0.50 liters/second on changes in lactic acid levels, as evidenced by the value of p=0.04 <0.05. The group that had the maximum results in reducing post-exercise lactic acid levels were variations (K4), (K3), (K1), and (K2).
