Brief summary
This study is a single-blinded, prospective, controlled trial aiming to evaluate the effect of supervised aerobic exercise on adipokine and myokine biomarkers in patients with breast or colon cancer during their systemic chemotherapy.
Detailed description
To determine the effect of aerobic exercise on adipokine and myokine biomarkers such as Interleukin-6 (IL-6), Irisin, Leptin and Adiponectin in the blood of breast or colon cancer patients receiving chemotherapy compared to ones who did not exercise during their systemic chemotherapy. Patients who were diagnosed with solid type of cancer specifically focusing on breast or colon cancer will be recruited either to the exercise group (EG) or control group (CG) during their systemic chemotherapy. An individualized supervised resistive aerobic exercise which will be performed via stationary resistive biycle ergometer will be implemented along with the chemotherapy process for EG. Each exercise session will be performed 2 times per week for at least 12 weeks (can be extended up to 24 weeks) during chemotherapy. Exercise intensity will be set as submaximal, 50-70% of heart rate reserve, and each session will be lasted 35 minutes. All exercise sessions will be supervised by the researchers to avoid potential side effects. 5 cc venous blood samples will be collected before the first and last chemotherapy infusions (for both EG and CG). The samples will be blinded to the analyzers did not know which group the samples belonged to.
Interventions
OTHERExercise
The exercise program will be started with 25 Watt (W) for 5 minutes of warm-up. Then it is steadily increased automatically by 5W in 5 minutes apart for 25 minutes for the loading period. The last 5 minutes which will be started by lowering the load to 25 W for cooling will be implemented for cooling down. To prevent acommodation, the warm-up period will be modified by increasing nearly 10% of its previous rate three weeks apart.A submaximal exercise prescription will be followed according to the American College of Sports Medicine guideline by taking into attention 50-70% of Heart Rate Reserve.A submaximal exercise prescription will be followed according to the American College of Sports Medicine guideline by taking into attention 50-70% of Heart Rate Reserve.
