Natural Antioxidant Intake After Exercise Can Oxidative Stress in the Third Trimester of Pragnancy

Study Overview
=================
Brief Summary
-----------------
Pregnancy is a condition that increased requirements of energy and oxygen, and if this condition is not maximally that can lead oxidative stress and produce free radicals which is affect in the pregnancy process. Malondialdehyde (MDA) level in pregnant women is higher than non-pregnant women. Exercise is one way to neutralize the free radical. The aim of this study was analyzed effect of treatment natural antioxidants after exercise which was pregnancy workout to MDA level in the third trimester of pregnancy. This study was a true experimental study. There were 24 prenatal pregnant women and separated to 3 groups, which were 8 prenatal pregnant women without pregnancy workout as a control group, 8 prenatal pregnant women with pregnancy workout but without natural antioxidant consume as a positive control group, and 8 prenatal pregnant women with natural antioxidant consume after pregnancy workout as a treatment group. The antioxidant compounds given in this study were guava juice that contains vitamin C. MDA levels was analyzed by spectrophotometric. Comparison between groups was done by one way ANOVA test.

Detailed Description
-----------------
Pregnancy is a condition that is vulnerable to all kinds - stress resulting in changes in physiology and metabolic function. In pregnancy there is also an increase in energy and oxygen requirements. The metabolic process can increase require of the oxygen and if it is not available as well as unmaximal used can causes the formation of oxidative stress and produces excessive free radicals which ultimately, that affected in the saferity of a pregnancy process. The imbalance between antioxidants and free radicals in pregnancy prosses are causes pathological and complications changes in pregnancy. This kind of biochemical marker of antioxidants and oxidants is very useful in observing complications that may arise in pregnancy. Treatment given is expected to eliminate complaints that arise while exercise during pregnancy can prevent the formation of free radicals, but exercise must be given in accordance with the ability of pregnant women. Physical exercise or exercise in pregnancy can maintain excess weight gain, prevent diabetes, hypertension, and shorten labor time. Sports is one way to neutralize the formation of free radicals because by doing physical activity, excessive oxygen can be used to produce energy. Increased free radicals are characterised by an increase of malondialdehyde (MDA) as a biochemical markers. Malondialdehyde (MDA) which is the output of lipid peroxidation prosses that measured to determine the presence of oxidative stress due to damage by free radicals. The resent study was found that MDA levels in pregnant women were higher compared to non-pregnant women. Increased MDA levels are in line with the increase in gestational age, from the first, second, and third trimesters. Study was also found that there was a significant increase in MDA levels accompanied by a decrease in non-enzymatic antioxidants, such as Vitamin-E, Vitamin-C, and Vitamin-A in pregnant women with hypertension. Moreover this study assums that was Giving Antioxidant to decrease Malondialdehyde (MDA) in the third trimester of pregnancy. futher more the aims of this study was analyzed effect of natural antioxidants treatment after exercise to MDA level in the third trimester of pregnancy. This study was a experimental study. This study was located in the several clinics midwife practice, Community Health Centers (Puskesmas) in Palembang and Bio Sains Riset Laboratory Palembang from August to October 2016. the study was approved informed consent from all participans as well as ethical clearance approval number is 007/UP-ETIK/I/2016. This study was obtained 24 prenatal pregnant women that separated to 3 groups, which were 8 prenatal pregnant women without pregnancy workout exercise as a control group, 8 prenatal pregnant women with pregnancy workout exercise as a positive control group and 8 prenatal pregnant women with consume natural antioxidants after pregnancy workout exercise as a treatment group. The antioxidant compounds given in this study were natural vitamin C from 100 ml guava juice without additionaly sugar, 5 cc syringe, cotton, alcohol, syringe, hanscoon, EDTA tube, serum, TCA 5%, Na thiobarbiturat 0,65%, MDA standart, and aquades. Spectrophotometric assay used to measure the MDA levels in the Bio Sains Riset Laboratory, Palembang and followed the essay of protocol kit from manufacture. Comparison between groups used by one way ANOVA test, that was considered significant if p < 0.05. All statistical analyses were done by SPPS for Windows version 16.0.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| MDA level | Malondialdehyde (MDA) levels is stress oxidative marker. MDA level messured with spectrophotometric assay. at Bio Sains Riset Laboratory, Palembang. Firstly, Mix 0.5ml blank + 0.5 ml standard and 0.5 ml serum using vortex mixer. Centrifuge for 10 minutes, with a speed of 2000 rpm, and Pipette 1 ml each filtrate and after that put it in boiling water bath for 30 minutes, then chill and read the absorbance with a spectrophotometer with a wavelength of 550 nm. | 7 days. |
