Performing sports activities along with the consumption of herbal supplements, especially in people, have different effects on the body's antioxidant and oxidant systems. The purpose of this research was to investigate the effect of eight weeks of intense interval training with chlorella supplementation on serum levels of malondialdehyde and total antioxidant capacity in obese or overweight middle-aged women. The statistical population of the present study consisted of overweight or obese middle-aged women (BMI ≤ 25) with an age range of 40 to 65 years. A number of 40 subjects were selected by invitation and based on the study entry criteria and randomly divided into four groups: exercise and supplement (10 people), exercise and placebo (10 people), supplement (10 people) and control (10 people). became HIIT exercises consisted of periods of 60 seconds of maximum intensity running (85-95% of the reserve heart rate) followed by 60 seconds of low-intensity running (55-60% of the reserve heart rate). The subjects did 6 times in the first week, 8 times in the second week. they completed the third to fifth weeks 10 times and the sixth to eighth weeks with 12 repetitions. Shapiro-Wilk test for normality of data and correlated t-test, one-way analysis of variance and Tukey's post hoc test to test hypotheses was used and the significant level was considered at the alpha level of 5%.

Background and Aim:The aim of the present study was to investigate the effect of two types of intense training on the levels of thioredoxin reductase-1 enzyme and malondialdehyde in testicular tissue of male wistar rats.Material and method:19 male Wistar rats,8weeks old and weighing200± 5g, after10 sessions of introducing training protocols and after weighing, were randomly divided into3groups(control, intense endurance training, intense training).Intense endurance training protocol included running on a treadmill for8 weeks and intense periodic training protocol included running on a rodent treadmill for 8 weeks. 48 hours after the last training session,the rats were anesthetized with ether and sacrificed and then the testicular tissue was isolated under sterile conditions.The amount of Thioredoxin Reductase-1 was determined by ELISA method and using a spectrophotometer and also the concentration of Malondialdehyde was determined by three Barbituric acid method using a spectrometer. One-way ANOVA with Tukey's post hoc test was used to analyze the data.Result:After8 weeks, the amount of Enzyme in the intense endurance training group and intense periodic training group increased significantly compared to the control group(P<0.05). Also,there was no significant change in the amount of Malondialdehyde in testicular tissue of the intense endurance training group and intense periodic training group compared to the control group(P>0.05).Conclusion: According to the results of this research,it can be said that intense endurance training and intense periodic training has increased the amount of thioredoxin reductase-1 enzyme in a testicular tissue and by creating adaptation in the body's antioxidant system, has not increased malondialdehyde.
