EFFECT OF MANGOSTEEN (Garcinia Mangostana L.) PEEL SUPPLEMENTATION ON ALKALINE PHOSPHATASE SERUM IN MALE STUDENTS AFTER HEAVY EXERCISE

Physical exercise can increase metabolism in the liver due to the presence of alkaline phosphatase
(ALP), which subsequently causes the oxidative stress. In order to reduce this effect, the consumption of natural
antioxidant is commonly performed, and one of these antioxidants could be found in mangosteen peel that
contains high content of Xanthone and Procyanidin. This study aims to understand the effect of mangosteen peels
to alkaline phosphatase serum in male student group who have performed heavy exercises. Methods: A true
experimental study was carried out with pre- and post-test, and 21 male students were recruited which were
divided into two groups. To understand the effect, a control group which was instructed to prescribe placebo
was involved, whereas the other group was invited to consume mangosteen peels with dosage of 550 mg as their
supplements. Both of the groups were prescribed for two weeks before performing the exercise, in which they
were invited to perform treadmill exercise which had 75%-85 of intensity for three times a week. The ALP
levels were measured on the final day of treatments after performing the heavy exercise. Results: A significant
rise of ALP levels were demonstrated by the control group with p value <0.05, in contrast the group who has
consumed the mangosteen peel as their supplements had significantly lower ALP levels compared to the
placebo group. Conclusion: It is concluded that mangosteel peels had the ability in lowering the ALP serum levels in male students who have performed heavy exercise.
