Obesity and inactivity are the main causes of cardiovascular and metabolic diseases; Although the role of physical activity on people's health has been reported, the type of exercise and the most favorable method of physical activity on improving body composition are still of interest to researchers. Therefore, the purpose of this study was to compare three methods of aerobic exercise, traditional resistance and TRX on the body composition of women in Sadra city. In this applied research, 24 women with an age range of 27 to 32 years and a weight range of 60 to 65 kg were selected as a statistical sample and randomly divided into groups of (1) aerobic exercise, (2) resistance exercise and (3) exercise TRX were split. Then, the subjects of each group performed the selected exercises for three sessions a week and each session lasted 40 to 60 minutes during the eight-week period. Body fat percentage, mineral mass, body protein mass, body water percentage and net body mass were measured in the pre-test and post-test of the research by BOCAX1 body composition evaluation device made in South Korea. It seems that the three methods of training did not have a significant difference in changing the body composition of women; Also, the factor of time and the number of training sessions along with daily calorie evaluation have been very important factors in the results of this research.

The imbalance in the prooxidant-antioxidant ratio causes uterine tissue damage. The aim of this study was to evaluate the effect of Pumpkin seed and aerobic training on mitochondrial biogenesis markers and DNA damage in uterine tissue in rats toxicated by hydrogen peroxide.

To implementation of this experimental research, 42 male wistar rats randomly were divided into 7 groups. All groups received 100 mg/kg body weight of hydrogen peroxide (H2O2) for 14 days intraperitoneal. Rats in supplemented groups received hydrophilic the rats received supplemental hydroalcoholic extract of pumpkin seeds at doses of 1 and 2 mg/kg body weight per day by gavage method. Aerobic training was performed on a treadmill at a speed of 23 m/min, 30 min/day, 5 days/week for eight weeks. 24 hours after the last training session, rat uterine tissue was collected. Data were analyzed using by Independent T-test, two-way ANOVA and Bonferroni post hoc test at P<0.05.

Combined intervention of pumpkin seed extract with aerobic exercise significantly increased methyl guanine levels and oxidant-prooxidant balance (PAB), as well as significantly decreased adenosine triphosphate (ATP) and malondialdehyde (MDA) levels in uterine tissue (P<0.05).

According to the results, supplementation of pumpkin seed with aerobic exercise can have a greater effect on improving mitochondrial biogenesis and reducing uterine tissue DNA damage.

Skeletal muscle atrophy is one of the most common muscle disorders that severely reduces the quality of life. Regular physical activities, especially resistance exercises, are one of the most important non-pharmacological interventions for the prevention and treatment of muscle atrophy. By increasing anabolic hormones, resistance training inhibits protein degradation signaling pathways and activates protein synthesis signaling pathways and reduces muscle atrophy. Many medicinal plants can also reduce muscle atrophy by inhibiting the signaling pathway of protein degradation and activating the signaling pathway of protein synthesis. Turmeric, tribulus terrestris, rice bran and ginseng are examples of medicinal plants that can inhibit muscle atrophy. According to the common mechanisms of resistance training and medicinal plants on the process of muscle atrophy, the results of studies show that these two interventions prevent muscle atrophy, especially in the conditions of skeletal muscle wasting diseases, by affecting the signaling pathway of muscle protein synthesis and degradation. do These two interventions in combination with each other have a synergistic effect and strengthen each other's effect. Therefore, the use of medicinal plants along with resistance exercises is an efficient way to maintain muscle mass.

The present study was conducted with the aim of comparing the effect of short-term use alone and a combination of L-arginine and L-citrulline supplements on the aerobic and anaerobic capacity of young soccer players.

n this semi-experimental study, which was conducted with a pre-test-post-test design, 60 young male soccer players with an age range of 15 to 18 years were selected as available and in 4 groups of 15 L-arginine supplement, L-citrulline supplement, combined of L-arginine, val-citrulline supplement and placebo. In the pre-test and post-test stages, the aerobic and anaerobic power of the subjects was measured using yo-yo tests and RAST test. The period of supplement consumption was for 7 days. The amount of L-arginine and L-citrulline supplements alone was 2.4 grams per day, and in the combined group, each of the supplements consumed 1.2 grams.

Short-term consumption (7 days) of L-arginine supplement, L-citrulline supplement and a combination of L-arginine and L-citrulline supplement on increasing aerobic power, peak anaerobic power, average anaerobic power, minimum anaerobic power and reducing the fatigue index of football players Young people have a significant effect (P>0.05). Other results indicate the greater effect of the combination of L-arginine and L-citrulline supplements compared to L-arginine and L-citrulline supplements alone in improving the aerobic and anaerobic capacity of young soccer players.

Based on the findings of the present study, it can be concluded that the combined use of L-arginine and L-citrulline supplements can be effective in increasing the aerobic and anaerobic capacity of young football players..

The use of cannabidiol oil supplement can control cardiovascular risk factors. Exercise can also be effective in the rehabilitation of heart attack by strengthening the heart tissue. Therefore, the purpose of this study was to investigate the effect of eight weeks of cannabidiol oil consumption and swimming exercise on the expression of AEA gene in heart tissue of rats suffering from myocardial infarction.

The present research was experimental. 25 rats with myocardial infarction were divided into five groups of 5 series: 1) healthy control, 2) MI, 3) MI + exercise, 4) MI + CBD, and 5) MI + exercise + CBD. Myocardial ischemia was induced by subcutaneous injection of isoproterenol (85 mg/kg intravenously) in myocardial infarction rats. The swimming training program was for eight weeks. The CBD supplement was given at a dose of 50 mg/kg during eight weeks. The data of the research was analyzed by one-way ANOVA and Tukey's post hoc test (p≥0.05).

AEA in the MI group had a significant decrease compared to the healthy control group (p=0.01). Compared to the MI group, only the MI group + swimming + CBD supplement showed a significant increase in AEA (p=0.01). Compared to the MI group, only the MI+swimming+CBD supplement group showed a significant increase in AEA (p=0.01).

Eight weeks of CBD oil consumption and swimming exercise can reduce heart tissue damage caused by isopretenol -induced myocardial infarction by increasing the expression of AEA.
