Background and Objective: An activity performed through a new motional pattern and very intensively often leads to a kind of muscle soreness whose indicator is delayed onset of pain, which is called Delayed Onset Muscle Soreness (DOMS). This study was done to determine the effect of vitamin C and E supplementation on lipid peroxidation and delayed onset muscle soreness in professional basketball players. Methods: In this clinical trial study, 24 male professional basketball players were randomly divided into four groups including vitamin C (1000 mg), vitamin E (800 IU), vitamin C (500 mg) + vitamin E (400 IU) and placebo (Glucose 500 mg). Supplement was consumed two hours before and 24 hours after leg press and scuat exercise. Blood samples were collected before the first supplementation and immediately (post- exercise), 24 hour and 48 hour after exercises. Serum creatine kinase (CK), malondialdehyde (MDA), vitamin C and vitamin E and the level of perceived muscle soreness were evaluated. Results: MDA in Vitamin E group significantly decreased in the 24-hr to 48-hr after the exercise in compared to bignning of exercise (P<0.05). Serum CK significantly increased 24-hr and 48-hr after the exercise in all groups (P<0.05). Muscle pain perception non significantly increased after the exercise in all groups in compare to baseline level. Conclusion: Short period supplementationin of vitamin C and E, either alone or in combination can not reduce pain and muscle damage and lipid peroxidation following the leg press and scuat exercise in professional basketball players.

Background and Objective: Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic hepatic diseases which may be associated with cardiovascular disease. This study aimed to consider the effect of combined therapy with resveratrol supplementation and interval exercise training on heart cells apoptosis in rats with NAFLD using TUNEL assay.
Methods: This experimental study was done on 35 Wistar rats. Animals were randomly allocated into five groups including control (healthy) and four NAFLD groups, including patient, resveratrol, interval exercise, and resveratrol + interval exercise. A TUNEL assay kit was applied for the detection of apoptosis in heart tissue.
Results: The patient group had significantly higher percentage of heart apoptotic cells (24.38±0.69%) compared to the other groups (P<0.05), while the resveratrol + interval exercise (9.02±0.49%) and resveratrol (9.47±0.83%) groups showed significantly lower mean levels of heart apoptotic cells compared to the patient and interval exercise (P<0.05) groups. There was no significant difference in mean of apoptotic cells between resveratrol and resveratrol + interval exercise groups. The mean of apoptotic cells in interval exercise group was 11.39±0.28%.
Conclusion: Nonalcoholic fatty liver disease is considerably associated with heart cells apoptosis. Resveratrol supplementation especially combined with interval exercise significantly reduces apoptotic cells in heart tissue.

Background and Objective: Acute ischemic preconditioning improves exercise performance. This study was done to determine the effect of four weeks of ischemic preconditioning on vascular grow factor (VEGF), lactate metabolism and fatigue indices.
Methods: In this clinical trial study, twenty inactive young men were randomly divided experimental (n=10) and control (n=10) groups. Subjects in experimental group perceived ischemic preconditioning (consisted of four 5-minute cycles of ischemia, followed by five minutes of reperfusion) for four weeks prior training. Blood samples were taken in the rest in order to measuring of VEGF. 48 hours prior and after the last intervention session, subjects performed an anaerobic Wingate test and rating the perceived exertion immediately and blood lactate were measured before, immediately, 5, 10 and 15 min after of Wingate test.
Results: 4-week IPC treatment significantly increased VEGF in compared to control group (138.2±8.2 vs 160.1±10.3) (P<0.05). Rating of perceived exertion (6.4±0.5 vs 6±0.1) and lactate accumulation in 15 min after exercise was significantly lower in experimental group in compare to controls (4.1±0.8 vs 5.6±1.2) (P<0.05). There was no significant difference between groups for power output (745.2±131.6 vs 769.7±148.6) and fatigue index (50.58±7.2 vs 46.2±11.8).
Conclusion: Four weeks of ischemic preconditioning increase VEGF and reduce rating the perceived exertion and blood lactate after intensive exercise in inactive young men.
