Abstract:
Objective: Exhaustive enduranceexercise can induce reactive oxygen species; ROS. It was important for sedentary to adaptation in regular exercise. We aimed to determine the effect of acute and trained exercise on antioxidant levels and nutritional status in sedentary people performing low intensity endurance exercise.
Methods: Nutritional status was assessed by body mass index (BMI) body fat, lean body mass, and waist to hip ration (WHR). The C-reactive protein (CRP), creatinine phosphokinase (CPK), lactic acid, and serum viramin E and retinol levels were determined.
Results: Twenty healthy sedentary volunteers with age range, 19-23 years old were enrolled. They were compared among pre-exercise, acute trained exercise at 4, and 8 weeks. There was significantly increased in vitamin E level after acute exercise (p<0.001), trained exercise at 4 weeks (p< 0.001) and 8 weeks (p<0.001). Vitamin E level higher in trained exercise at 4 weeks than in acute exercise (p = 0.004). BMI was significantly lowered inacute exercise (p<0.001) and trained exercise at 4 weeks (p = 0.025) compared to pre-exercise. Lean body mass was significantly declined in acute exercise (p<0.001), trained exercise at 4 (p=0.001) and 8 (p = 0.002) weeks compared to pre-exercise. There wassignificantly reduced in weight to hip ration in trained exercise at 8 weeks than in pre-exercise (p = 0.013).
conclusion: Significant higher higher in vitamin E level were found in sedentary who performed low intensity exercise compared to pre-exercixe. Levels of nutritional status was differed among acute and trained exercise bout. Thus, vitamin E might be the sensitive biomaker affected after sedentary attended in low intensity endurance training exercise. The protein supplementation should be taken into consideration.
