NCT07540559

Brief Summary

This study aims to investigate the effects of daily coffee consumption on balance performance in healthy university students. Caffeine is a widely consumed psychoactive substance that may influence neuromuscular control, reaction time, and postural stability. Participants will be categorized based on their habitual caffeine intake levels, and balance performance will be assessed using standardized clinical tests. The results are expected to contribute to the understanding of the relationship between caffeine consumption and balance performance.

Outcome Measures

Primary Outcomes (4)

  • Single Leg Stance Test

    The Single Leg Stance Test will be used to evaluate static balance. Participants will be asked to stand on one leg for as long as possible without support. The duration will be recorded in seconds.

    Single assessment at baseline

  • Y Balance Test

    The Y Balance Test will be used to evaluate dynamic balance. Participants will reach in anterior, posteromedial, and posterolateral directions while maintaining single-leg stance. Reach distances will be measured in centimeters.ere measured in centimeters.

    Single assessment at baseline

  • Timed Up and Go (TUG) Test

    The Timed Up and Go (TUG) test will be used to assess functional mobility and dynamic balance. Participants will be instructed to stand up from a chair, walk 3 meters, turn around, walk back, and sit down. The total time to complete the task will be recorded in seconds.

    Single assessment at baseline

  • Tandem Walking Test

    The Tandem Walking Test will be used to assess dynamic balance. Participants will be instructed to walk in a heel-to-toe manner along a straight line. Performance will be recorded based on time and/or number of errors.

    Single assessment at baseline

Secondary Outcomes (1)

  • Borg Rating of Perceived Exertion (RPE) Scale

    Single assessment at baseline

Study Arms (3)
