Aim: The aim of the present investigation is evaluate the effect of L- Arginine supplements on the oxidative and nitrosative stress in liver of rats following acute exercise on a treadmill. Method: Thirty two male Vistar rats (160-210 g) were randomly divided into four groups: control (C); L-Arg treatment (Arg); exhaustive exercise (E); and exhaustive exercise with L-Arg treatment (E + Arg). E and E+Arg groups performed a 1 hour acute running test, or until exhaustion on a treadmill (16-26 m/min) and Arg and E+Arg groups treated orally with the L-Arg (2% diet, for 30 days). Sampling was performed 1 hour after exercise. Nitric oxide production was evaluated by measuring nitrite formation, using Griess reagent. oxidant-Antioxidant’s ratio was measured as TOS/ TAC levels. Results: According to the means of the oxidant-antioxidant’s balance (E)=0.91±0.12, (SC+Arg)=0.92 0.04 and (E+Arg)=0.91±0.09, TOS/TAC decreased in (E), (SC+Arg) and (E+Arg) groups compared with control group (SC); however, this decrease was not significant. And the results showed nitric oxide in (SC) group (mean=9.01 6.31 ) was more than other groups, but there was no significant change in there. Conclusion: The results of the present study didn’t show existence of oxidative-nitrosative stress and supplementation effect in muscle 1 h after acute exercise.

Abstract
Aim: Cardiac disorder is a disease that affected many people. This disease not only affects the body but also results in depression and anxiety. The purpose of this study was to determine the effectiveness of two months exercise rehabilitation on anxiety and somatisation of CABG patients.
Method: Our subjects were 60 patients that were under surgery in one of the city’s main hospitals. From these, 930 patients who went to cardiovascular research center were put in the exercise rehabilitation group and 30 patients who did not go to rehabilitation were put to the control group. Then rehabilitation group performed 90 minutes exercise session 3 times per week for 8 weeks and the control group did not experience any beneficial physical activities. Subjects completed the SAS questionnaire before and after the rehabilitation program.In doing so we were able to assess the amount of anxiety and somatisation.
Results: The findings demonstrated that there was a significant decrease in anxiety in exercise rehabilitation group compare to the control group (p=0.014). In addition, we observed reduction in somatisation but it was not statistically significant (p= 0.25).
Conclusion: Exercise rehabilitation may be a good method to prevent mental disorder and modify the post effects of coronary artery bypass surgery.

Abstract
Aim: The purpose of this study was to determine the proper height of hurdles for ten consecutive double-legged jumps in plyometric training
Method: The sample included 45 female (height: 165 ±5 cm and weight: 56.0 ±6.4 kg) and 35 male (height: 177 ± 6 cm and weight: 68.8 ±7.3 kg) volunteers. Two different tests of height jumps over hurdles, namely "1 repetition maximum jump (1RMJ)" and "10 repetition maximum jumps (10RMJ)" were administrated in two separate sessions 48 hours apart from each other. The rate of drop in height of 10RMJ (compared to 1RMJ) was divided into three groups of "15 cm and lower", "20-25 cm", and "30 cm and higher".
Results: Discriminant analysis showed that for 59% of cases, 1RMJ height could estimate 10RMJ height correctly. Furthermore, by the means of multiple regression analysis, an equation was produced to estimate proper height of 10RMJ from 1RMJ height. Accordingly, there was a variation of 10 to 35 cm in the drop rate of 10RMJ in different individuals. There was no relation between anthropometric measures and jump height. The best predictor of 10RMJ was 1RMJ.
Conclusion: It is likely that the technique of jump, which determines the energy cost of every jump, would have a vital impact here. It is suggested to determine the height of hurdles for different number of consecutive jumps apart from 10 repetitions by the use of the same study design.
