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.

Aim: One of the complications of menopause that plays an important role in reducing the quality of life is the reduction of body fat-free mass. The aim of this study was to determine the effect of a period of whole body vibration course on myostatin and follistatin Serum in Postmenopausal Women. Methods: In this semi experimental study, 20 postmenopausal women with hypothyroidism were selected and divided into two groups of 10: control (C) and whole body vibration training (V). Group V performed these exercises for 12 weeks and three times a week, with a frequency of 30 to 50 Hz, applying on upper and lower limb training. At the beginning and end of the study, blood serum myostatin and follistatin levels were measured using the ELISA method, , body fat percentage, body mass index, and body weight. Due to the normality of data distribution, independent t and covariance statistical methods were used for analysis at a significance level of 0.05. Results: 12 weeks of whole body vibration training in group V significantly increased the serum levels of follistatin (P=0.001), and decreased myostatine (P=0.018) compared to the control group. There was also a significant decrease in body fat percentage (P=0.041), body mass index (P=0.044) and weight (P=0.047).Conclusions: It seems that whole body vibration training increases serum levels of follistatin and decreases myostatin in postmenopausal women, and these positive changes may play an important role in improving lean mass of postmenopausal women.
