Abstract
Aim: Diabetes mellitus is a metabolic syndrome which is determined by insulin deficiency-induced hyperglycemic or decrease of in body insulin sensitivity. Chronic inflammation conditions in diabetes are associated with Cyclooxigenase 2 enzyme (COX-2) expression. The major metabolites of this enzyme, which play an important role in cardiovascular homeostasis are Prostocyclin (PGI-2) and Tromboxane (TXA-2). However, Prostocyclin is a potent vasodilator and prevents platelet aggregation and Tromboxane causes vasoconstriction, proliferation of smooth muscles and aggregation and remodeling of platelets. The present study investigates the effect of 8 weeks of resistance training on the expression of COX-2 enzyme and its metabolites such as TXA-2 and PGI-2 in wistar diabetic male rats.
Method: For this purpose, in an experimental study 24 wistar rats were purchased from Pasteur Institute of Iran and divided into resistance training (n=12) and control (n=12) groups. The resistance training protocol included 8 weeks (3 sessions per weeks) of ten sets of ladder ascending with free weights were attached to the rats’ tails (70 to 75% of maximum capacity of carrying free weights by each rat).The animals were sacrificed 48 hours after the last session of training program and blood samples were taken. After the left ventricle was drained, stimulatory and inhibitory factors were measured and the data was analyzed by t-test via spss16 software.
Results: The results of independent t-test showed that there was a significant decrease in blood glucose (P

Abstract
Aim: Despite the large amount of proteins in the plasma, the urine is virtually protein free due to the selectivity of the glomerular barrier. Various physiologic settings, including exercise, can induce a transient increase in the urinary protein excretion that is usually benign and reversible. Several studies have reported postexercise proteinuria in healthy adults. However, there is little information about this phenomenon in adolescents. Therefore, the purpose of this study was the comparison of exercise-induced proteinuria after a semi-soccer protocol and a soccer match in male adolescents.
Method: Twenty-two adolescent male soccer players (age 14-16) were selected for this study and randomly assigned to soccer match or semi-soccer protocol groups. Urinary samples were gathered in form of 24-hours samples before and 24 hours after completion of exercise protocol.
Results: The result showed that completion of both the semi-soccer protocol and the soccer match caused significant increase in urinary excretion of total protein, creatinine, beta2microglobulin and gama glutamyle transfrase (p>0.0001). Also, in post-test, urinary excretion of all noted indexes was slightly higher in the soccer group but the difference was not statistically significant.
Conclusion: Changes in renal hemodynamics, glomerular basement membrane permeability, blood acidity, membrane charge, and hormonal and enzymatic alterations induced by exercise probably cause increase in glomerular permeability and disturbance of tubular reabsorbtion and it causes the excretion of low and high molecular weight protein in urine after exercise.
Key words: Exercise-induced proteinuria, Beta-2-microglobulin, Gama glutamyle transfrase, Creatinine

AbstractAim: The purpose of this study was to obtain normative values of body fat percent for athlete and non-athlete male adolescent in Tehran city.
Method: For this reason, 619 boys (11-12 years of age) including 306 athletes among 8 sports (with mean weight 33.9±6.0 kg and height 142.4±6.9 cm) and 313 non athletes (with mean weight 33.2±7.6 kg and height 140.5±6.7 cm) were selected randomly and participated in this descriptive study. Body fat percent calculated using slaughter equation and normative values of body fat percent for both athletes and non-athletes were obtained using descriptive statistics.
Results: The findings showed that normative values of body fat percent for athletes were in ranges of 8.72-19.09. Normative values of body fat percent for non-athletes were in range of 8.36-18.73. However, there were no significant differences between norms of body fat percent in athletes and non athletes.
Conclusion: With respect to result of this study, cultureal programs account into consideration for promotion knowledge about adverse effects of sedentary life especially in children and adolescents.
Key words: Norm, Body fat percent, Athlete, Non-athlete
