Objective: Aerobic training and Saffron has decreasing effects on apoptosis induced by exercise to exhaustion. The present study aims to investigate the Interactive effect of aerobic training with Saffron extract on BAX and Bcl2 proteins of cardiac tissue in trained rats following an aerobic exercise until exhaustion. Methods: This is a clinical trial, 48 Wistar male rats were assigned into following four groups (N=12): control )C) , Saffron extract) SE) , Aerobic training (AT) , Aerobic training + Saffron extract (AT+SE). Aerobic training was done for five times a week for 8 weeks. Saffron extract was administrated through oral gavage 100 mg.kg-1.day-1. The end of experiment, half of the rats was killed immediately before exhaustive training; on the other hand, remaining rats were killed immediately after performing an acute bout of exhaustive exercise on the treadmill. BAX and Bcl2 proteins levels were measured by ELISA method. The data were analyzed using a one-way ANOVA, with the significance level of P < 0.05. Results: following an exhausting BAX and Bcl2 proteins of cardiac tissue in the all groups Except in the AT+SE group were significantly increased and decreased respectively (P < 0.05). Conclusion: It seems that aerobic training and use of saffron extract Each one alone or in combination with each other prevented the significant change of Bax and Bcl2 proteins and BAX/Bcl-2 ratio following an exhausting exercise.

AbstractAim: Recently, the attention of sports science researchers has increased to the role of supplements that help to improve executive functions in addition to improving physical performance. The purpose of this study was to investigate the effectiveness of sodium bicarbonate supplementation on the executive functions of athletes before and after exhausting exercise.Method: 30 male athletes were randomly divided into 2 groups of 15 (supplement consumption group before the exhausting test and supplement consumption group after the exhausting test). The modified coocani test was considered as a training protocol. Continuous performance and N-back tests to measure attention and working memory were measured before conconi test and in four other stages. Data analysis was done by the method of mixed ANOVA and using SPSS 26 software.Results:The findings showed that the group that had taken sodium bicarbonate supplement before the conconi test performed significantly better than the other group in the attention and working memory tests (P<0.05). Conclusion: Acute consumption of sodium bicarbonate supplement both before exercise and as a recovery supplement improves attention and working memory after exercise.Keywords: Sodium bicarbonate, Exhausting exercise, Young athletes, Executive functions
