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%.

Alzheimer's disease is a neurodegenerative disease. In this disease, the accumulation of beta-amyloid plaques in the brain causes a decrease in nerve density and the volume of the hippocampus. Studying the types of sports activities and finding the best type is considered as a way to control Alzheimer's. The aim of the current research was to study the effect of six weeks of continuous aerobic training on the neuronal density of the hippocampus CA1 region and memory performance.The current research was carried out experimentally. The statistical population was male Wistar rats with a weight range of 300 to 350 grams. For this purpose, 40 11-month-old male rats were prepared and randomly divided into four groups of 10 including the training patient group, control patient group, healthy training group and healthy control group. The rats performed the relevant exercises for six weeks by repeating five sessions per week. 48 hours after the last session, brain tissue was removed and data were collected. Neuronal density was measured by histological method and memory performance by novel object recognition test. The results were extracted using two-way variance analysis at a significance level of p≥0.05.Neuron density in the hippocampus in the training patient group increased significantly compared to the control patient group. Also, improvement of memory performance was observed in the training patient group compared to the control patient group (p=0.004). Performing continuous aerobic exercises for six weeks increases the neuronal density in the hippocampus and improves memory function in Alzheimer's disease.

Aim: choosing the type of sports activity for better effect in obese people can be considered as an important factor and challenge. On the other hand, Spexin plays a central and peripheral role in regulating satiety and food intake, motility of the digestive tract, energy metabolism and glucose/lipid metabolism. Therefore, the present study was conducted with the aim of comparing the effect of eight weeks of aerobic exercise and 30-20-10 on serum levels of spexin and lipid profile indices of obese men. Methods: The present experimental study and its statistical sample were 30 obese men who were randomly assigned to two groups of aerobic exercise and 30-20-10 exercise (15 people in each group). Aerobic exercise and 30-20-10 exercise were performed for eight consecutive weeks. Before and after the start of the protocol, height, weight, maximum oxygen consumption blood sampling from the brachial vein were performed to evaluate the amount of spexin and lipid profile.Results: The inter-group results showed that there was a significant difference in the levels of SPX and total cholesterol between the two groups of aerobic exercise and 30-20-10 exercise, so that by examining the difference in means, the greatest effect was after aerobic exercise. P = 0.001 and P = 0.005). But HDL levels were not significantly different between the two groups (P=215).Conclusion: According to the results of the present study, it is likely that aerobic exercise has a better effect on the serum levels of spexin and cholesterol in obese people than 10-20-30 exercises.
