|THE EFFECT OF PACITAN SWEET ORANGE JUICE TO MALONDIALDEHYDE LEVEL (MDA) AFTER ECCENTRIC ACTIVITY|
|Pacitan sweet Orange Juice, Malondialdehide Level, Eccentric Activity|
Objectives: This research aim is to evaluate the effect of Pacitan orange Juice to Mallondialdehide Level (MDA) after doing Eccentric Activity Methods: This is an experimental laboratories with post control group design. 30 male students of Sport Science Faculty between 18 to 20 years old were recruited by purposive random sampling. The sample was divided into two groups, 15 people as experimental and 15 people as control. Both groups performed pull up activities, which include two sets with seven repetitions, and one minute paused. After completing pull up activities, 750 ml of orange juice was given to the experimental group, while control group got 750 ml of mineral water. After 1 hour, each group took blood-sampling test to determine the levels of malondialdehide and lactic acid after eccentric exercise. Result: The result showed that the average MDA of control group was 8.489 ± 2.55 while mean MDA of treatment group was 6.095 ± 1.99. The t-test showed significant results between the control group and the treatment group with pvalue = 0.008 <0.05 Conclucions: Pacitan orange juice revealed decrease the MDA levels after having eccentric activities. With regard to this, it can be concluded that with this treatment can respond to free radicals. The response is able to counteract ROS, which is containing the high antioxidant.
