Introduction: Alzheimer's is a destructive brain disease that causes progressive cognitive disorders for which there is no cure. The aim of the present study was to investigate the effect of aerobic exercise along with the consumption of saffron extract on spatial memory and the amount of tau protein accumulation in the hippocampal tissue of Alzheimer's induced male rats.Method: In this experimental study, 32 adult male rats were randomly divided into 4 Alzheimer's groups including control, aerobic exercise, aerobic exercise, extract and extract. Aerobic exercises including 3 training sessions per week were performed for 8 weeks. Y maze test was used to check spatial memory and ELISA method was used to measure tau protein. One-way analysis of variance was used to analyze the data.Findings: The results showed that after 8 weeks of aerobic training with saffron supplement, there was a significant increase in spatial memory performance in the intervention groups compared to the control group (P < 0.5). Also, regarding the amount of tau protein accumulation in the aerobic exercise group, aerobic exercise and extract showed a significant decrease compared to the control group (P < 0.5).Conclusion: It seems that aerobic exercise and consumption of saffron extract improves spatial memory performance and reduces the accumulation of tau protein in the hippocampal tissue of Alzheimer's male rats.

Aim: High intensitystrength and endurance training can increase exercise capacity. The aim of this study was to describe the effect of high intensity strength and endurance training on body fat index, glucose homeostasis and serum leptin of 15 to 20 year old Taekwondo players boy. Method: Of the eligible volunteers in the study, 20 taekwondo players aged 15 to 20 were selected as the research sample. The subjects were randomly divided into two groups: moderate-intensity resistance-endurance training (the first group, the mean age was 17.77 ± 2.26 years) and high intensity (second group, 16.90 ± 1.72 years). The first group, , had moderate intensity and endurance training for 95 minutes, and the second group performed high intensity training for 80 minutes. Along with the conventional taekwondo exercises Before and after 8 weeks training, body fat index, glucose hemeostasis and serum leptin were assessed. For data analysis, dependent t-test and independent t- test were used. p < strong>Results: Compared with the pre-test, in the second group a significant decrease was observed in the body fat percentage, insulin and insulin resistance levels. Leptin and FBS significantly decreased after exercise in both groups. The Comparison between groups showed only significant difference in body fat percentage (P=0.03).. Conclusion: High intensity strength and endurance training in athletes can potentially lead to significant reduction in subcutaneous fat. Decreased serum leptin and glucose levels and improved insulin sensitivity can improve the taekwondo lpayers performance
