EFFECT OF RED FRUIT ON RATS'S MALONDIALDEHYDE LEVEL AT MAXIMAL PHYSICAL ACTIVITY

The cells continuously produce free radicals and reactive oxygen species (ROS) as a part of metabolic processes. These free radicals are neutralized by an antioxidant defense system. Maximal physical activity can produce an imbalance between ROS and antioxidants and thus caused oxidative stress, which is possibly related to fatigue and tissue injury. Red fruit oil contains high betacarotene and tocopherol. This study investigated the effect of red fruit oil on malondialdehyde level in maximal physical activity. This study used pretest-posttest control group design. Twenty four rats were divided into 4 groups. The control group (I) was administered with 1.5 ml distilled water, intervention groups (II), (III) and (IV) were administered with different doses of Red Fruit Oil (0.5 ml, 1.0 ml, and 1.5 ml/day, respectively). All groups were trained to swim for 4 weeks and then were forced to swim without a load until being exhausted. The malondialdehyde (MDA) and time to swimming to exhaustion were measured. Analysis showed that MDA level obtained was decreasing significantly (P<0.5) and time of swimming was increasing significantly (P>0.5) in the intervention groups. The results conclude that red fruit oil can obviously to reduce MDA level VCO and increase endurance and delay fatigue induced by maximal physical activity in rat.
