Acute Exercise

This study aims to compare acute thyroid hormone and cortisol responses to aerobic and anaerobic exercise in sedentary women. Thirty sedentary women aged 18-25 years will voluntarily participate in the study. Participants will complete a 20-meter shuttle run test as the aerobic exercise protocol and a 30-second Wingate test as the anaerobic exercise protocol in separate testing sessions. Blood samples will be collected immediately before and after each exercise protocol. Serum thyroid-stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and cortisol concentrations will be determined using chemiluminescence-based laboratory methods. Changes in hormone concentrations will be compared between the aerobic and anaerobic exercise conditions.

Cancer has emerged as a prominent cause of mortality in the 21st century, with breast cancer (BC) being the most diagnosed malignancy. Multidisciplinary cancer management has improved survival chances, but side effects and long-term consequences of treatments have significant implications for cancer survivors' health-related quality of life. Exercise is increasingly considered and used in cancer treatment and follow-up. However, studies demonstrating the biological mechanisms underlying the anticarcinogenic effects (ACE) of exercise are insufficient to justify the most appropriate physical activity for different clinical scenarios. Achieving scientific excellence in understanding the ACE of exercise in cancer management is critical to optimize treatment and enhance patients' quality of life.
