Introduction: Silybum marianum is an annual or biannual herbaceous species of the Asteraceae family. The medicinal effects of this plant are due to the presence of a group of flavonolignans which is called silymarin. It has been suggested that silymarin has anti -inflammatory, antioxidant properties and could stabilize cell membranes and regulate cell permeability and could prevent the appearnance of some of the undesirable muscle damage indices in patients and even athletes. Hence, the aim of this study was to determine the effect of silymarin intake on some mascular damage markers in serum of active males after the one session aerobic exercise.

Methods: Twenty-two active males (mean age 25.09±2.11 years, body fat 13.56±1.94% and VO2max 50.5±4.88 ml/kg-1/min) were divided into two homogenous groups of 11 subjects (supplement and placebo groups) in a semi-experimental, randomized and double-blind design (6 mg.kg-1.day silymarin or Dextrose). After 7-days of supplementation, all subjects participated in aerobic exercise protocol including running on the treadmill at the 0% grade for 30 min with 65-70% HRreserve. Changes in muscle damage indices (total serum CK and LDH, AST) were determined in four phases (baseline, after supplementation period, immediately and 24 hours after the exercise). Data were analyzed by repeated measure ANOVA, bonferroni, and independent t test at α≤0.05 level of significance.

Results: The results showed that after 30 min aerobic exercise, the levels of serum muscle damage enzymes significantly increased immediately and 24 hours after exercise in Silymarin and Placebo groups (P≤0.05). However, after 24 hours of aerobic exercise, all of muscle enzymes activity was signficiantly higher in Placebo group in comparison with Silymarin group (P≤0.05).

Conclusions: Based on the present findings, it could be concluded that silymarin supplementation could significantly decrease further aerobic exercise-induced muscle damage in active males.

Introduction: Menopausal women face many problems including osteoporosis. One of the preventive ways to avoid osteoporosis and its complications is regular activity and participation in sports. So, the aim of this study was to evaluate the effect of 16 weeks of Pilates exercises on bone mass density in menopausal women.
Methods: Therefore, 30 menopausal women were selected as subjects and randomly divided into two groups of control and exercise. The training group practiced Pilates for 16 weeks. T-score, L1-L4 lumbar region and femoral neck of both groups were measured by Stenosis densitometer (DEXA), before training, after 8 weeks and after 16 weeks of training. A comparative test of repeated measurements with intergroup factors was used for examining data.
Results: Results shows that the interaction between time and group is significant (p< 0.05). Bone density of the lumbar vertebra was reduced after 8 weeks of Pilates workouts, which wasn’t significant. But there was a significant increase after 16 weeks of workout compared to 8 weeks (p<0.05). Also, this density ratio shows a significant increase in interaction with the control group after 16 weeks of workout. Similar results were seen in femoral neck density with lumbar vertebrae.
Conclusion: It seems that doing Pilates workouts by menopausal women, has a significant effect on bone mass density after a long time. Therefore training method of Pilates is an appropriate training method for menopausal women.

Introduction: Intense exercise damages tissues and disturbs some cellular processes through oxidative stress and antioxidants can modulate intense exercise-induced oxidative stress. The aim of the current study is to examine the effect of short-term selenium on serum hydrogen peroxide (H2O2) and Glutathione (GSH) supplementation of inactive male university students, following a session of acute exhaustive aerobic training.
Methods: The present study is a semi-experimental study with a cross-sectional design, which was conducted at the laboratory of the University of Birjand in the year 1397. 10 inactive male university students at the average age of 18.60 ± 0.84 and BMI of 21.38 ± 3.61 ml/kg/min were randomly selected for this research. The 10-member group attended four stages, called control, training, supplementation, and training + supplementation group, in a cross-sectional way. The training protocol which has been used in the test was Bruce Protocol. After attending one training session, the subjects took selenium supplementation in the form of capsules (200 mg daily) for 14 days. Immediately after the training, the blood samples were taken from arm vessels and was analyzed. For the determination of the normal distribution of data, the Shapiro-Wilk test has been employed. Then an analysis of variance repeated measure test and dependent t-test were used for extraction of results at the significant level of p<0.05.
Results: The results showed that following acute exhaustive aerobic training, H2O2 serum levels have increased significantly (p=0.01) and then significantly decreased (p=0.001) by taking selenium supplementation for 14 days (p=0.001); however, after training and selenium supplementation, GSH serum levels did not show any significant changes (p=0.27).
Conclusion: Since taking selenium supplementation for 14 days could significantly decrease the high H2O2 levels, following a session of acute exhaustive aerobic training, it seems that this supplementation can have a positive effect on the oxidative stress, caused by acute training.

Introduction and purpose: Sexual dysfunction is common among women and takes a toll on quality of life. The purpose of this study was to assess the effects of both aquatic exercise and fennel consumption on multiple domains of sexual function and estradiol level in women.
Materials and Methods: In this semi-experimental study with pretest-posttest design, 30 females aged 20–40 years were randomly assigned to three major groups of exercise-placebo, exercise-supplement, and control. Aquatic exercise was carried out at moderate intensity, three days per week for 8 weeks. The participants in the fennel group received oral soft capsules containing 100mg of fennel twice a day for 8 weeks and women in the placebo group received the same doze of placebo capsules containing 100mg of sunflower oil. Female Sexual Function Index (FSFI) and blood samples were collected 48 h before and after the last sessions of exercise training. Estradiol was assessed using ELISA assay. Data were analyzed using repeated measures ANOVA and SPSS Software v.21.
Results: Total FSFI score (P= 0.01) as well as desire (P= 0.01), arousal (P= 0.03), satisfaction (P= 0.04), orgasm (P= 0.05) and lubrication (P = 0.04) in the exercise-placebo group improved significantly compared to the control group. Furthermore, sexual function (P=0.01) and estradiol level (P=0.02) were significantly improved in exercise-supplement group, compared to exercise-placebo group.
Discussion and Conclusion: Combination of aquatic exercise with fennel consumption may increase estradiol level, and improve sexual function in women.
