Professional and amateur e-sports players aged 18-30 years recruited from Istinye University and affiliated e-sports organizations. Professional players are defined as individuals who engage in structured gaming for at least 25 hours per week, are affiliated with a competitive team, participate regularly in official tournaments, and receive income or sponsorship related to gaming. Amateur players engage in 15 hours or less of recreational gaming per week, are not affiliated with professional teams, and do not receive gaming-related income. All participants are healthy volunteers without medical conditions affecting physical performance.
Amateur e-sports players:
Exclusion Criteria:
Participants who engage in structured gaming ≥25 hours per week, are affiliated with a competitive team or organization, participate in official tournaments at least once per month, and receive income or sponsorship related to gaming.
Participants who engage in ≤15 hours of recreational gaming per week, are not affiliated with a professional team, and do not receive income or sponsorship from gaming.
BlazePod Reaction Time
Reaction time will be assessed using the BlazePod wireless light system. Participants will respond to randomized visual stimuli by tapping illuminated pods as quickly as possible. The mean reaction time (milliseconds) from three trials will be used for analysis. Lower values indicate faster reaction performance.
Time frame: At baseline
Yo-Yo Intermittent Recovery Test
Total distance (meters) completed during the Yo-Yo Intermittent Recovery Test, reflecting cardiorespiratory endurance.
Time frame: At baseline
Hand Grip Strength
Maximum grip strength (kg) measured using a Camry EH101 dynamometer. The highest value from two trials per hand will be recorded.
Time frame: At baseline
Wall Sit Test
Total time (seconds) participants maintain a 90-degree wall sit position, indicating lower-limb muscular endurance.
Time frame: At baseline
Push-Up Test
Total number of correctly performed push-ups completed without rest, representing upper-body muscular endurance.
Time frame: At baseline
Sit-and-Reach Test
Maximum reach distance (cm) achieved during flexibility assessment.
Time frame: At baseline
Body Mass Index
BMI calculated as weight (kg) divided by height (m²).
Time frame: At baseline
Y-Balance Test
Normalized reach distance (%) in anterior, posteromedial, and posterolateral directions to assess dynamic balance.
Time frame: At baseline
Countermovement Jump
Maximum vertical jump height (cm) calculated using the difference between standing reach and jump reach.
Time frame: At baseline
IPAQ-SF
Total physical activity expressed in MET-minutes per week.
Time frame: At baseline
