Abstract
In physical activity, in addition to forming free radical compounds, the body will form antibodies in the form of endogenous antioxidants. In the event of an imbalance in the formation of free radicals with antioxidants (oxidative stress) exogenous antioxidant administration will help to restore the balance of free radicals with - antioxidants. Provision of vitamins and massage manipulation immediately after physical exercise is expected to help in decreasing levels of MDA Plasma as one indicator of the degree of free radical in the blood and helps speed up the recovery of the body.
It is an experimental research with post-test control group design with sample of 20 college students of Unipa Surabaya. Which is divided into 2 groups with each group amounted to 10 college students. The group is Control group and Vitamin E group. The all group performed 2.4 km run, the treatment was given after the sample did the physical activity. After 1 hour of treatment each group was taken by radially to see blood MDA plasma levels.
After processed data got average of plasma MDA level of each group that is control group with mean 8,0870 nmol/ml, vitamin E group with average 2,9020 nmol/ml. From the statistical t test obtained of P value < 0.05. Thus, there was significant difference of MDA Plasma level between control group and vitamin E after physical exercise.
ABSTRAK
Dalam aktivitas fisik, selain membentuk senyawa radikal bebas, tubuh akan membentuk antibodi dalam bentuk antioksidan endogen. Jika terjadi ketidakseimbangan dalam pembentukan radikal bebas dengan antioksidan (oksidatif stres) maka pemberian antioksidan eksogen akan membantu mengembalikan keseimbangan radikal bebas dengan - antioksidan. Penyediaan vitamin dan manipulasi pijat segera setelah latihan fisik diharapkan bisa membantu dalam menurunkan kadar MDA Plasma sebagai salah satu indikator tingkat radikal bebas dalam darah dan membantu mempercepat pemulihan tubuh.
Penelitian ini merupakan penelitian eksperimental dengan desain kelompok kontrol post-test dengan sampel 20 mahasiswa Unipa Surabaya. Yang terbagi menjadi 2 kelompok dengan masing-masing kelompok berjumlah 10 mahasiswa. Kelompok ini adalah Kelompok kontrol dan kelompok Vitamin E. Semua kelompok melakukan lari 2,4 km, perlakuan diberikan setelah sampel melakukan aktivitas fisik. Setelah 1 jam pengobatan, masing-masing kelompok diambil secara radial untuk melihat tingkat plasma darah MDA.
Setelah data yang diolah didapatkan rata-rata kadar MDA plasma masing-masing kelompok yaitu kelompok kontrol dengan rata-rata 8,0870 nmol/ml, kelompok vitamin E dengan rata-rata 2.9020 nmol/ml. Dari uji statistik diperoleh nilai P <0,05. Dengan demikian ada perbedaan tingkat MDA Plasma yang signifikan antara kelompok kontrol dan vitamin E setelah latihan fisik.
Penelitian ini menunjukan bahwa dengan pemberian vitamin E setelah latihan fisik dapat membantu menurunkan kadar MDA Plasma yang merupakan indicator tingkat radikal bebas.
