اثر محدودیت کالریایی حاد و یک جلسه تمرین ایروبیک با موسیقی خوشایند و ناخوشایند بر کورتیزول و سروتونین سرم زنان ورزشکار

Research Aim: Apply of caloric restriction during training and heavy competitions may lead to the development of psychosomatic disorders such as depression by increasing the cortisol and reducing the serotonin mediated intermediate in brain and body fluids. Therefore, it seems that the use of music can lead to modification of undesirable hormonal changes.The aim of this semi-experimental study was to evaluate the effect of acute caloric restriction and one-session aerobic training with pleasant and unpleasant music on serum cortisol and serotonin in female athletes. Research Method:For this purpose, 20 healthy female athletes (aged between 23 and 40) were studied in pleasant music (n=10, weight 71.51 5.84 kg, height 159.90 6.27 cm) and unpleasant music (n=10, weight70.07 12.54 kg, height 157.60 4.62 cm) groups. Both groups do tow- sessions exactly the same high impact aerobic training with (65 -85 ) MAX HEART RATE for 115 minutes. Blood samples were taken in 4 steps, immediately before and after the first and second exercise sessions, about 5 milliliters of mixed blend with 5ml syringes from the pre-elbow vein by experienced staff nurse. Statistical analysis was performed (P?0.05) by Shapirovilke, independent t-test and Bonferroni. Charts were plotted using Excel software.Findings: The response of cortisol to both (pleasant and unpleasant) music groups with and without caloric restriction was almost similar, increasing and significant (p<0/05). The response of serotonin to both (pleasant and unpleasant) music groups with and Continuation of thesis abstract without caloric restriction was almost similar, increasing and significant (p<0/05). The variation pattern in both the pleasant and unpleasant music groups was similar, and no significant difference was observed between the two groups at the four stages of measurement (p>0/05).Conclusion: Despite the meaninglessness between two pleasant music and unpleasant music groups, results show musical effectiveness. Therefore, it is suggested that when exercising a relatively high calorie restriction, before exercising at least pleasing music playback is included as a way to moderate depression indices
