Detailed Description
This single-group interventional study is designed to examine acute changes in selected blood biomarkers following aerobic exercise in professional soccer players. A total of 20 professional male soccer players aged 18-25 years will voluntarily participate. Participants will be recruited from a professional soccer club in Karabuk, Türkiye. Before participation, all individuals will receive information about the study procedures, provide written informed consent, and undergo medical screening to determine their eligibility for maximal aerobic exercise.
Body height and body mass will be measured before exercise testing. Aerobic exercise will be performed using a progressive 20-meter shuttle run test. Participants will run continuously between two lines positioned 20 meters apart while following prerecorded audio signals. Running speed will progressively increase as the interval between the audio signals decreases. The test will end when a participant fails to reach the designated line before the audio signal on two consecutive occasions.
Venous blood samples of approximately 5 mL will be collected immediately before and immediately after the exercise protocol by qualified healthcare personnel. Blood samples will be collected into anticoagulant-free serum tubes. Following a clotting period of approximately 30 minutes, the samples will be centrifuged at 3,000 revolutions per minute to separate the serum. Serum samples will be stored at -70°C until laboratory analysis.
Serum ferritin, folate, vitamin B12, and parathyroid hormone (PTH) concentrations will be measured. Pre- to post-exercise changes in each biomarker will be analyzed separately to determine the acute physiological responses elicited by aerobic exercise in professional soccer players.

Intervention / Treatment |
|---|---|
|
Experimental: Aerobic Exercise
All participants will complete a progressive 20-meter shuttle run test.
Venous blood samples will be collected immediately before and immediately after the exercise protocol to assess acute changes in serum ferritin, folate, vitamin B12, and parathyroid hormone concentrations.
|
Participants will perform a progressive 20-meter shuttle run test by running continuously between two lines positioned 20 meters apart in time with prerecorded audio signals.
Running speed will progressively increase as the interval between the audio signals decreases.
The test will end when the participant fails to reach the designated line before the signal on two consecutive occasions.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Change in Serum Ferritin Concentration From Pre-Exercise to Immediately Post-Exercise
Time Frame: Immediately before exercise and immediately after completion of the 20-meter shuttle run test
|
Venous blood samples will be collected immediately before and immediately after the 20-meter shuttle run test.
Serum ferritin concentration will be measured in ng/mL.
For each participant, the change will be calculated by subtracting the pre-exercise value from the post-exercise value.
The group-level outcome will be summarized using the mean change and standard deviation.

Change in Serum Folate Concentration From Pre-Exercise to Immediately Post-Exercise
Time Frame: Immediately before exercise and immediately after completion of the 20-meter shuttle run test
|
Venous blood samples will be collected immediately before and immediately after the 20-meter shuttle run test.
Serum folate concentration will be measured in ng/mL.
For each participant, the change will be calculated by subtracting the pre-exercise value from the post-exercise value.
The group-level outcome will be summarized using the mean change and standard deviation.

|
Change in Serum Vitamin B12 Concentration From Pre-Exercise to Immediately Post-Exercise
Time Frame: Immediately before exercise and immediately after completion of the 20-meter shuttle run test
|
Venous blood samples will be collected immediately before and immediately after the 20-meter shuttle run test.
Serum vitamin B12 concentration will be measured in pg/mL.
For each participant, the change will be calculated by subtracting the pre-exercise value from the post-exercise value.
The group-level outcome will be summarized using the mean change and standard deviation.

|
Change in Serum Parathyroid Hormone Concentration From Pre-Exercise to Immediately Post-Exercise
Time Frame: Immediately before exercise and immediately after completion of the 20-meter shuttle run test
|
Venous blood samples will be collected immediately before and immediately after the 20-meter shuttle run test.
Serum parathyroid hormone (PTH) concentration will be measured in pg/mL.
For each participant, the change will be calculated by subtracting the pre-exercise value from the post-exercise value.
The group-level outcome will be summarized using the mean change and standard deviation.
