Background and Objective: Fibrinogen, an inflammatory marker as well as a fundamental part of the coagulation cascade, is suggested to play a significant role in the pathogenesis of atherosclerosis and complications of atherothrombotic diseases. This study was carried out to assess the comparison of acute aerobic and resistance training method on plasma fibrinogen concentration in young women. Materials and Methods: This semi-experimental study was done on twenty trained volunteer women students, which was selected objectively, and availability. The subjects were randomly divided into two groups of aerobic (n=10) and resistance training (n=10). Aerobic group performed exhaustive workout program on treadmill intensity 65 to75% of Vo2max on treadmill. The resistance group completed three sets of 5-7 repetitions of six exercises at an intensity corresponding to 80% of 1RM. Following 12 to 14 hours of nightly fasting, venous blood samples (5 cc) were collected pre, immediately after exercise and after 60 min of recovery and analyzed for fibrinogen content. Participants were matched according to anthropometric measurements, age, fat percentage and Vo2max. Data tested by using independent t, repeated measures analysis of variance and post-hoc test least significant difference (LSD) (P≤0.05). Results: In both the aerobic and resistance training groups, fibrinogen levels increased immediately after exercise and remained higher than baseline levels during recovery. This changes were significant only in aerobic group (P<0.05). Resistance training increased significantly the fibrinogen levels immediately after exercise than aerobic exercise (P<0.035). Conclusion: It can be concluded that the exhaustive aerobic exercise may induce slightly increase the fibrinogen levels in comparison with resistance training at intensity corresponding to 80% of 1RM.

Background and Objective: Oxidative damage associated with the presence of Lead in the brain has been proposed as one possible molecular mechanism involved in Lead toxicity. Aerobic exercise is known to protect the brain through a cascade of molecular and cellular processes. The purpose of this study was to investigate the effect of 8 week aerobic training on the brain-derived neurotrophic factor (BDNF) and malondialdehyde (MDA) levels in rat's cerebellum exposed to Lead acetate. Materials and Methods: In this experimental study, 40 Male Wistar rats were randomly allocated into four groups: sedentary base, sham (30 mg/kg of ethyloleate), Lead and exercise+Lead (20 mg/kg Lead acetate, intraperitoneally). The exercise program consisted of progressive running training on the treadmill for 15 to 22 m/min, 25 to 64 min/day, and 5 days/week for 8 weeks. BDNF and MDA levels were measured by ELISA and TBARS methods, respectively. Results: Chronic Lead acetate administration enhanced significantly (P<0.05) cerebellar MDA levels in rats compare to base and sham groups but had no effect on BDNF levels. Cerebellar MDA significantly was reduced and BDNF non significantly was increased in Lead acetate+ training group. Conclusion: Regular aerobic exercise with moderate intense may exert role neuroprotective against Lead-induced cerebellar injury by down-regulating oxidative stress and promotes brain health through increases in BDNF.

Background and Objective: Oxidative stress plays a major role in the structural and functional changes of the myocardium due to diabetes. This study was done to determine the effect of swimming training and arbutin supplement on cardiac antioxidant enzymes and oxidative stress in diabetic rats. Methods: In this experimental study, 42 male Wistar rats were randomly allocated into 6 groups including control, diabetes, Arbutin, diabetes+Arbutin, diabetes+exercise and diabetes+ exercise + Arbutin (combined). Diabetes induced using alloxan (90 mg/kg/bw, intraperitoneally). Arbutin (50 mg/kg/bw, ip) was administered for 5 days a week. The exercise consisted of swimming training at 5 min to 36 min per day, 5 days a week for 6 weeks. Renal Malondialdehyde, catalase level and superoxide dismutase (SOD) activity were evaluated in animals. Results: Diabetes significantly increased cardiac Malondialdehyde level and decreased cardiac SOD activity and catalase level (P<0.05). Six weeks of supplementation with Arbutin, swimming training and combined intervention significantly increased catalas level and superoxide dismutase activity compared to the diabetes group(P<0.05). Malondialdehyde level significantly reduced in combined and exercise groups in comparison with diabetic group (P<0.05). Conclusion: Regular training (swimming) and Antioxidant supplement (Arbutin) protect the cardiac tissue against diabetes-induced oxidative stress through their antioxidants capacity and the combination of the two interventions have synergic effect.

Background and Objective: Liver diseases accompanied with growing of obesity in children. This study was done to evaluate the effect of aerobic exercise and vitamin C intake on liver transaminases activities in 8-11 years obese girls.

Methods: In this quasi-experimental study, 28 obese girls were randomly divided into four equal groups including control, exercise, supplement (500 mg vitamin C tablet, dailly) and combined (500 mg vitamin C, daily plus exercise) groups. Aerobic exercise was consisted of exercise movements at 50% to 70% maximal heart rate and 3 sessions per week for 8 weeks. Fasting blood samples were collected before and 48 hour after the last intervention. Serum transaminases activities were measured by enzymatic colorimetric method.

Results: 8 weeks of aerobic exercise, vitamin C and the combined intervention were associated with a significant reduction in Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) activities (P<0.05) whereas there was no effect on the Alkaline phosphatase activity. All these interventions were associated with significantly greater reduction in the ALT and AST activities ratio in comparision with control group. Combined intervention induced more reduction on percent of variables changes compared with other interventions (P<0.05).

Conclusion: It seems selected aerobic exercise and vitamin C intake may induce their protective effect in obese girls via improvement in liver function.

Background and Objective: Aging eldely is associated with impaired angiogenesis, glomerulosclerosis and increased susceptibility to nephrotoxic injury. This study was done to compare the independent and combined effect of aerobic exercise and garlic extract on the levels of renal vascular endothelial growth factor (VEGF) and transforming growth factor-β1 (TGF-β1) in eldely rats.

Methods: In this experimental study, 35 aged eldely male Wistar rats were randomly allocated into 5 groups including control, sham, garlic (2.5 g/kg/bw), aerobic exercise, garlic plus exercise. The animals exercised by swimming training at 5 min to 60 min per day, 3 days a week over 8 weeks. Animals in garlic plus exercise were received garlic extract (2.5 g/kg/bw) and swimming training. The renal TGF-β1 and VEGF level were evaluated by ELIZA method.

Results: 8 weeks swimming training, garlic supplementation and the combined intervention were associated with a significant increased the renal VEGF and reduced TGF-β1 level (P<0.05). There was no difference between swimming training, garlic supplementation and garlic plus exercise on renal VEGF and TGF-β1 levels in aged rats.

Conclusion: It seems that the protective role of regular swimming training, garlic supplementation and the combined intervention in the renal aging process meight in part be related to their ability to attenuate TGF- β1 and up regulating VEGF.

Background and Objective: The acute exercise leads to the induction of some cardiac and inflammatory biomarkers that are related to factors such as severity, type, training experience, gender and environment. This study was conducted to compare the effect of acute endurance and resistance training at two different intensity levels of high-sensitivity cardiac Troponin T (hs-cTnT) and tumor necrosis factor alpha (TNF-α) in male runners and bodybuilders.
Methods: In this quasi-experimental study, 20 male runners and bodybuilders with an age range of 20-24 years were purposefully and accessibly selected. The study was performed with a pre-test-post-test design on 10 male runners (endurance training) and 10 bodybuilding men (resistance training). The runners ran 6 km with moderate (70-75% of reserve heart rate) and high (85-85% of reserve heart rate) intensities at intervals of one week, during separate sessions. Bodybuilders also performed resistance training at moderate (70-75% of one repetition maximum) and high (80-85% of one repetition maximum) intensities.  Bodybuilders also performed resistance training at moderate (70 to 75% of a maximum repetition) and high (80 to 85% of a maximum repetition) intensities. Blood samples were taken before and immediately after exercise. Then the serum levels of hs-cTnT and TNF-α were measured.
Results: The serum level of hs-cTnT and TNF-α was significantly increased after acute running and resistance training with moderate and high intensities (P˂0.05), but intense acute exercise had a greater effect on increasing the levels of these variables. Also, the acute effect of intense aerobic exercise was associated with a greater increase in hs-cTnT level in compared to moderate-intensity aerobic exercise, high and moderate-intensity resistance training (P˂0.05).
Conclusion: In endurance and resistance athletes, the hs-cTnT and TNF-α responses are affected by the intensity of training and increase more with intense training. But the high intensity aerobic exercise is associated with a greater increase in hs-cTnT levels.

Background and Objective: Vitamin deficiency is common in patients with chronic low back pain and is one of the most important risk factors for chronic kidney disease. The aim of this study was to evaluate the effect of one course of core stabilization exercise and vitamin D intake on some of renal function biomarkers in patients with chronic back pain.
Methods: This single-blind clinical trial study was done on 48 women with chronic low back pain with random assignment in 4 groups of 12 people including control, exercise, vitamin D and combined groups. The exercise and combined groups performed 8 weeks of core stabilizing exercises with different levels. The vitamin D and combined groups received 50,000 IU vitamin D/week. Creatinine, urea and uric acid levels were measured before and after the interventions.
Results: The results showed that 74.26% and 25.64% of the patients had deficiency and insufficiency of vitamin D, respectively. After 8 weeks, significant reduction was observed in creatinine, urea and uric acid indicators of the exercise, vitamin D and combined groups (P˂0.05). In addition, combined intervention induced more reduction in mean of urea, and uric acid levels in compared to the two other interventions but the effect of exercise on the reduction of uric acid was more than vitamin D intake (P˂0.05).
Conclusion: Both core stabilization exercises and vitamin D intake intervention can be effective in improving renal function in chronic low back pain patients having abnormal low vitamin D levels. On the other hand the combined intervention seems to have more effectiveness.

Background and Objective: Vitamin D increases muscle strength through protein synthesis and myogenesis and may play an important role in anaerobic and aerobic activities. This study was done to determine the vitamin D status and its relationship with physical function indexes in young Taekwondo athletes.
Methods: This descriptive-analytical study was conducted on 75 young male Taekwondo athletes, aged 18-23 years that were selected using randomized sampling method. Serum 25-hydroxyvitamin D level was measured by ELISA method. The 20-meter shuttle run, running based anaerobic sprint (RAST), vertical jump, 36-meter sprint and Illinois agility tests were used to determine aerobic and anaerobic capacities, explosive anaerobic power of the lower limbs, speed and agility, respectively. Body mass index and percent body fat was measured for each subject. Level below 20, 20-30 and more than 30 ng/ml of serum 25-hydroxyvitamin D were considered as vitamin D deficiency, insufficiency and normal status, respectively.
Results: The results showed that 48% (36 athletes) and 42.66% (32 athletes) of taekwondo athletes had deficient and insufficiency levels of vitamin D, respectively. Also, a significant correlation was detected between serum 25-hydroxyvitamin D concentration and aerobic power (r=0.897), anaerobic power (r=0.901), vertical jump performance (r=0.855), fatigue index (r=-0.838), agility (r=-0.634) and 36 meters sprint (r=-0.793) times (P<0.05). However, this association was significant in athletes with lower than normal levels of vitamin D (P<0.05), no association was found in subjects with normal vitamin D levels.
Conclusion: Vitamin D of 90.66% of young taekwondo practitioners was lower than normal level. Increasing in vitamin D level can improve the physical performance of young athletes with vitamin D deficiency or insufficiency status.

Background and Objective: Sedentary life and vitamin D deficiency are considered as related factors to increased inflammation and oxidative stress in obese individuals. This study was performed to determine the effect of Pilates training with vitamin D supplement on Monocyte chemoattractant protein-1(MCP-1) level and superoxide dismutase (SOD) activity in overweight men.
Methods: In this single-blind clinical trial, 56 overweight men were randomly assigned to control, Pilates, vitamin D and combination groups. The Pilates training was performed for 8 weeks with the intensity of 50-75% of reserve heart rate, 3sessions/week. The vitamin D and combination groups received 50,000 units of vitamin D per week. The levels of MCP1 and SOD activity were in the first and 8 weeks after interventions.
Results: Vitamin D status in subjects was lower than normal level. MCP-1 level in Pilates, vitamin D and combination groups significantly reduced and SOD activity increased after 8 weeks (P<0.05), but the combined intervention had a stronger effect on the modulation of MCP-1 level and SOD activity compared to the other two interventional groups (P<0.05). In addition, the effect of Pilates exercises on increasing SOD activity was more than vitamin D intake (P<0.05).
Conclusion: It seems that Pilates training and Vitamin D intake can be exert their protective effects in overweight individuals with abnormal vitamin D status by an increase on the SOD activity and decreasing the inflammatory index of MCP-1. Although these effects developed with combined intervention, Pilate training was associated with greater increases in antioxidant levels than vitamin D.

Vitamin D deficiency affects a broad range of health-related factors. Both obesity and vitamin D deficiency are associated with the development of oxidative stress and systemic inflammation. Inflammation can culminate in decreased vitamin D levels through the induction of oxidative stress. Evidence suggests that exercise may improve vitamin D status. However, the effects of exercise interventions on inflammation and oxidative stress in the coexistence of vitamin D deficiency and obesity/overweight are not well-established. Therefore, this review aimed to evaluate the effects of exercise on inflammation and oxidative stress in vitamin D deficiency status accompanied by obesity/overweight. A search for articles from 2006 to 2023 was conducted in specialized databases of PubMed, Scopus, and state inpatient database (SID). The searched studies were original research articles, reviews, and clinical trials selected using the keywords of vitamin D deficiency, systemic inflammation, oxidative stress, chemokine, exercise, obesity, and overweight. According to the studies, regular exercise can inhibit the vicious cycle of oxidative stress-inflammation in vitamin D deficiency status accompanied by obesity/overweight by negatively regulating some inflammatory factors and chemokines, reducing lipid peroxidation levels, and increasing antioxidant status. Moreover, the increase in 25-hydroxyvitamin D levels resulting from exercise can be considered another mechanism for reducing oxidative stress-inflammation in vitamin D deficiency status accompanied by obesity/overweight.
