Effect of Zinc Rich Sesame Nutribar on the Physical Activity of Rats
Exercise is the stressor that can perturb body zinc homeostasis because it increases zinc loss and exercise is also the potent stressor that influences circulating zinc concentration in the blood affecting the physical performance of a person. Zinc added in the diets increases muscle strength and improves the endurance performance. The data on the effect of zinc supplementation in the dietary form and the endurance level of the athletes were found to be limited. The zinc supplements in the form of pills causes side effect, therefore an attempt was made to find out a dietary zinc supplement and its effect on the physical performance of rats. To find the effect of formulated sesame nutribar on the performance of the rats, 28 days supplementation protocol was carried out on a rat model. The desiccated coconut nutribar designed for the athletes containing 0.06mg (Experimental -I) and 0.08mg (Experimental-II) of dietary zinc were supplemented and a basal diet was fed to the control group (CGP) and physical training test was performed and evaluated. The rats of CGP were found to perform less in the swim test than Exp-I and Exp-II with F value being highly significant (p<0.01), thus indicating the effect of zinc present in the sesame nutribar. The data indicates the supplementation of the dietary zinc in the form of sesame nutribar improved the physical performance of the rats and thus can be used in place of elemental zinc.
