Despite of that regular exercise training with appropriate intensity, as essential component of a healthy lifestyle, to induce a desirable and beneficial adaptation in the body, however, has demonstrated that exhaustive and strenuous exercises causes oxidative stress, inflammatory response, and structural damage to muscle cells, as well as decline in athletic performance. Therefore, there has been much effort to identify appropriate sport supplementation strategies that may help to reduce or prevent exercise-induced muscle damage and stress. So that, due to its antioxidant and anti-inflammatory properties, the use of herbal medicines and natural supplements maybe very effective to prevent exercise-induced muscle damage and oxidative stress. Hence in the present review, in addition to study of possible mechanisms, it has provided the effects of some natural and herbal supplements in sports. For this review, all relevant information were collected using search of some keywords such as natural supplement, herbal supplement, herbal and natural supplement and exercise performance, herbal and natural supplement and muscle damage via some internal and external databases including Web of Science, Pubmed, Google Scholar, Science Direct, Magiran, IranDoc and SID, that this information was extracted without time and geographical location limit (all time periods until 2021). The results indicated that the athletes are among those who use the herbal and natural supplement for their own benefit and it has been recognized that some herbs may help them to improve their performance, speed up recovery and reduce biomarkers of muscle damage. In conclusion, it seems that herbal and natural supplementation could exert preventive effects from exercise-induced muscle damage and oxidative stress by its antioxidant and anti-inflammatory properties, and some of these supplements have an ergogenic aids and improve physical performance in athletes.

Increased inflammation is a consequence of diabetes. Accordingly, the use of herbal medicine as a solution has been suggested. The objective of this study was to evaluate the effect of two months of chia supplementation in conjunction with inflammatory and anti-inflammatory responses in male Wistar diabetic rats.

36 diabetic rats were randomly assigned to 3 equal groups (control group, diabetes group, diabetes + chia group) and were subjected to 8 weeks of supplementation. Interleukin-1 and interleukin-13 were measured in soleus muscle tissue to examine the inflammatory and anti-inflammatory indicators. ANOVA and Tukeychr('39')s post hoc test were used for data analysis.

Although chia supplementation had aggravating effects on IL-1ß compared with the diabetic group, this effect was not statistically significant (p = 0.99). Also, IL-13 protein expression increased significantly in the diabetic control group by about 51% (p = 0.001), and in the diabetic group with chia supplementation by about 50% (p= 0.001) compared to the healthy control group. There was no significant difference between the two groups.

It seems that two months of chia supplementation with this dose and period of consumption could not have a positive effect on anti-inflammatory factors in male diabetic rats. Confirmation of this finding requires further research in this area.

  The most common and clinically important complication in adults with diabetes is cardiovascular diseases (CVDs). Exercise training and pomegranate have been recognized to ameliorate CVDs. The aim of this study was to examine the protective effect of aerobic training along with pomegranate juice concentrate on cardiac injury biomarkers in women with type 2 diabetes. In this study, 33 women with type 2 diabetes were selected from Babol City and were randomly divided into four groups (control, pomegranate concentrate, training and pomegranate concentrate+training). The training groups participated in a progressive aerobic training for six weeks, three sessions a week (60% to 75% of reserved heart rate and for 25 to 45 min). The groups of pomegranate concentrate and pomegranate concentrate+training were provided 150 mL of pomegranate juice concentrate for six weeks (at about 18 p.m). Two days before and after the protocol, their blood samples were taken in fasting state. The results showed that Troponin T, CK-MB and LDH were decreased significantly in the experimental groups (p=0.000, p=0.014 and p=0.034, respectively), whereas significant reduction of Troponin I and CK was observed only in the pomegranate concentrate+training group (p=0.048 and p=0.041, respectively). It seems that aerobic training and pomegranate juice concentrate and combination of both reduce cardiac injury biomarkers in women with type 2 diabetes

The purpose of this study was to investigate the effect of ginger supplementation on the gene expression of catalase (CAT), glutathione peroxidase (GPX), superoxide dismutase (SOD) enzymes and malondialdehyde (MDA) levels.
In a semi-experimental trial, 20 students with 20-25 years old from Shahed were selected and randomly divided into experimental (10) and control (10) groups.
The experimental group received one gram of ginger capsule at the doses of 250 mg, four times a day, for eghit weeks. Control subjects, also received placebo (maltodextrin) in the same manner. Blood samples were taken 72 hours before the start and 72 hours after the completion of the research protocol. The statistical methods of Kolmogorov-Smirnov, t dependent and independent, as well as SPSS (version 22) and Excel were used (P There was no difference between the groups in the gene expression of the antioxidant enzymes and MDA levels (p = 0.144 for SOD, p = 0.234 for cat, p = 0.1 for GPX, and p = 0.201 for MDA). In the experimental group, ginger supplement lead to significant reduction in MDA levels (p = 0.01).
According to the results of this study, it can be said that eghit weeks of supplementation of ginger may reduce the lipid peroxidation without affecting gene expression of antioxidant enzymes.

Many women in menopause have changed that part of these changes cause by decreased blood flow which is secondary to decreased estrogen. These changes may result in decreased their sexual activity. The aim of this study was to assess the effect of Ginkgo biloba extract (GBE) on sexual activity in 50 – 60 years menopausal women. In this Randomized placebo-controlled trial 80 healthy female volunteers aged 60 – 50 years، attending three health-care centers of Tehran University of Medical Sciences (TUMS)، were enrolled. The participants provided written informed consent and then received GBE at a dose of 120–240 mg (n = 40) or placebo (n = 40) daily for 30 days. The instrument of this study was the Sabbatsberg Sexual Rating Scale (SSRS) which the part of it evaluate sexual activity before and after intervention. Finally، the results were analyzed by using Fisher exact test، Independent samples- t test and Mann-Whitney Test. 27 menopausal women (45. 2 %) were in the 50 – 52 year group. Menopause age in the 29 women (45/9) was 50 years or more. After intervention، sexual activity had no significant difference between the two groups of Ginkgo biloba and placebo. Despite the effectiveness of the herbal supplement Ginkgo biloba in sexual desire in women، the results showed no effect on their sexual activity. With regard to the efficacy of many herbal supplements may appear after prolonged use، it is recommended that the next studies assess the effect of prolonged use of this plant.
