Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
These types of exercise cause various hormonal, immunological, and metabolic changes in the body. After exercise, significant changes are observed in biomarkers such as stress hormones (cortisol, progesterone), anabolic hormones (testosterone), immune system markers (IgA, TNF-α, IL-6, IL-10, IL-1β, IL-1RA, IL-4), and metabolic parameters (amylase, insulin, lactate). The fact that these parameters can be measured from both blood and saliva samples has increased the use of non-invasive methods in exercise physiology studies.
The level of physical activity is directly related not only to biological systems but also to an individual's psychological health and lifestyle habits. Research shows that regular physical activity reduces levels of depression and improves quality of life. The positive effects of exercise on the immune system become more significant when considered in conjunction with an individual's general lifestyle habits (nutrition, sleep, stress levels, substance use, etc.). It is particularly known that individuals with depression have high cortisol levels and suppressed IgA levels. Therefore, depression levels and lifestyle habits are important variables that affect the physiological responses to exercise.
This study will compare the effects of aerobic and anaerobic exercise on hormonal, immunological, and metabolic biomarkers measured via blood and saliva samples in young individuals. Additionally, the participants' physical activity levels, depression levels, and general lifestyle habits will be evaluated to explore the relationship between these variables and biomarker profiles. Measurements will include levels of testosterone, progesterone, cortisol, IgA, alpha-amylase, insulin, lactate, and various inflammatory cytokines, assessed using the ELISA method. In this way, the biological effects of different types of exercise will be evaluated from both physiological and psychosocial perspectives.
The main aim of this study is to comparatively examine the effects of aerobic and anaerobic exercises on hormonal, immunological, and metabolic biomarkers measured through blood and saliva samples in young individuals. Additionally, the relationship between the participants' physical activity level, depression level, and general lifestyle habits (nutrition, sleep patterns, substance use, etc.) with these biomarkers will be investigated, as well as the potential modulatory effects on the physiological responses to exercise.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group I - Control Group:
This group will not receive any training intervention. Participants will only undergo the Bruce Protocol and Wingate tests to serve as a baseline reference for physiological responses, allowing comparison with the other two groups.
No interventions assigned to this group
Group II - Treadmill Exercise (Bruce Protocol):
Participants will perform the Bruce Protocol on a treadmill, which involves progressive stages of increasing speed and incline to challenge cardiovascular endurance. At each stage, heart rate, blood pressure, and fatigue level will be recorded. The session will end with a cool-down phase.
Treadmill Exercise
Participants in this group will perform an aerobic exercise using the Bruce Protocol on a treadmill. The test involves walking or running with gradually increasing speed and incline in predefined stages to assess cardiovascular endurance. Heart rate, blood pressure, and fatigue levels will be recorded at each stage. The session will conclude with a low-intensity cool-down phase.
Group III - Bicycle Exercise (Wingate Anaerobic Test):
This group will perform the Wingate Anaerobic Test using a stationary exercise bike. Following a warm-up, participants will cycle at maximum effort for 30 seconds to assess anaerobic performance. Data collected will include pedaling speed, power output, heart rate, and oxygen saturation.
Bicycle Exercise
The Wingate Anaerobic Test will be conducted using an ergometer bike. After a standardized warm-up, participants will pedal all-out for 30 seconds against a preset resistance, aiming to evaluate their anaerobic performance. Physiological parameters including power output, heart rate, and oxygen saturation will be monitored throughout the test.
