    Abstract
    ABSTRACT The effects of methanol extract from the rhizome ginger (Zingeber officinale roscoe) on strenuous exercise program was studied in plasma and gastrocnemius muscle samples obtained from male Mus Musculus L mice. Methanol extract was given in oral doses of 0,07 mg/g, 0,14 mg/g, and 0,28 mg/g of mice body weight before exhaustive swimming exercise program, daily for a period of five days. The plasma and gastrocnemius muscle samples from the mice were subjected to biochemical analysis after exhausted swimming in the fifth day to determine the level of malondialdehyde (MDA) of the plasma and gastrocnemius muscle. The administration of 0,07 mg/g of ginger’s extract did not give any change of the malondialdehyde level in the plasma as well as in the gastrocnemius muscle. On the other scene, the administration of 0,14 mg/g of the ginger’s extract will reduce the plasma level of malondialdehyde, but not statistically significant, and reduce the level of malondialdehyde in gastrocnemius muscle significantly (p<0,05). While the administration of 0,28 mg/g of ginger’s extract precisely increasing the level of malondialdehyde, this condition probably caused by the transition of anti oxidant into pro oxidant in the higher dose of ginger’s extract. In conclusion, the most effective dose of methanol extract from Zingeber officinale Roscoe to reduce the level of malondialdehyde is 0,14 mg/g. Key words : methanol extract of rhizome ginger, strenuous exercise, gastrocnemus muscle and malondialdehyde.
     
    ABSTRAK Pengaruh pemberian ekstrak metanol rimpang jahe (Zingeber officinale Rosc.) telah dipelajari pada sampel plasma dan otot gastroknemius mencit jantan Mus Musculus L. Ekstrak metanol rimpang jahe diberikan secara oral dengan dosis 0,07mg/gBB, 0,14mg/gBB dan 0,28mg/gBB mencit sebelum berenang maksimal sampai lelah setiap hari selama lima hari. Sampel plasma darah dan otot gastroknemius mencit diambil segera setelah perlakuan renang maksimal selesai pada hari kelima, untuk dilakukan pemeriksaan kadar malondialdehid plasma dan otot gastroknemius. Pada pemberian 0,07mg/gBB mencit ekstrak metanol rimpang jahe, tidak mampu menurunkan kadar MDA plasma dan otot gastroknemius setelah latihan fisik maksimal. Sementara itu, pada pemberian dosis ekstrak metanol rimpang jahe sebesar 0,14mg/gBB dapat menurunkan kadar MDA plasma meskipun tidak signifikan, dan juga dapat menurunkan kadar MDA otot gastroknemius yang secara statistik signifikan (p<0,05). Sedangkan pada kelompok perlakuan yang mendapat ekstrak metanol rimpang jahe paling besar yaitu 0,28mg/gBB malah terjadi peningkatan kadar MDA yang mungkin disebabkan antioksidan berubah menjadi prooksidan pada dosis yang terlalu tinggi. Kesimpulannya ekstrak metanol rimpang jahe dengan dosis 0,14mg/gBB ,paling efektif menurunkan kadar MDA plasma dan otot gastroknemius mencit yang mendapat latihan fisik maksimal. Kata kunci: ekstrak metanol rimpang jahe, latihan fisik maksimal, otot gastroknemius dan malondialdehid.
