摘要：Resistance exercise associated with muscle tissue damage, needs recovery immediately. Protein is the major nutrient that plays roles in tissue damage recovery. Drink made from tempeh extract is rich in protein content that may be used for muscle damage recovery. The aim of this research was to evaluate the effect of administering tempeh extract on muscle damage recovery. A double blind control trial method was applied in this study. Eighteen semi-trained men (18-24 y) were randomly divided into three groups (n = 6 each) i.e: group 1 received tempeh-extract (contain~23 g protein), group 2 received whey drink (contain~23 g protein) and the third group which received placebo drink, after exercise. Subjects performed resistance exercise with load of 75% of maximum strength (1 RM) with squats which was divided into six set of fifteen repetition with a 2 minute rest interval between sets. Creatine kinase level (CK), muscle strength and muscle soreness as marker of muscle damage were recorded before exercise and at six, 24, 48, 72 and 96 h post exercise. Administering of tempeh-extract drink significantly decreased the CK level and increased maximal strength at 24 h compared to placebo group, however no significantly different in muscle soreness.
