The Effect of Turkish Coffee on Postural Control and Hand-eye Coordination in Young Adults

Not Applicable

Completed

• Conditions: Caffeine; Coordination and Balance Disturbances; Balance; Distorted
• Interventions: Other: Caffeine intake

• Registration Number: NCT06561113
• Lead Sponsor: Bezmialem Vakif University

Brief Summary

Although the effects of different doses of caffeine on balance have been evaluated in various studies, the effects of low doses of caffeine ingested with Turkish coffee on postural control and hand-eye coordination remain unclear. In this study, it will be investigated the acute effects of 60 mg caffeine intake via Turkish coffee on postural control and hand-eye coordination.

Detailed Description

This study is designed as a one-group pretest-posttest quasi-experimental research. The study will be conducted with healthy young adults with low coffee consumption habits. Participants who meet the inclusion and exclusion criteria will undergo postural control assessment with the Biodex Balance System® and hand-eye coordination test with the Alternate Hand Wall Toss Test. Subjects will be given 65 ml of Turkish coffee (one cup) to ensure oral caffeine intake. The same assessments will be repeated 30 minutes after caffeine intake.

Arm && Interventions

Group	Intervention	Description
Study group	Caffeine intake	Participants who meet the inclusion and exclusion criteria will undergo postural control assessment with the Biodex Balance System® and hand-eye coordination test with the Alternate Hand Wall Toss Test. Subjects will be given 65 ml of Turkish coffee (one cup) to ensure oral caffeine intake. The same assessments will be repeated 30 minutes after caffeine intake.

Primary Outcome Measures

Name	Time	Method
Postural control assessment with Biodex Balance System	Baseline and immediately after caffeine intake	Postural control evaluation will be performed with "Biodex Balance System" (Shirley, NY). Three tests will be performed with the device: postural stability test, stability limits test, and the Modified Clinical Test for Sensory Interaction and Balance (mCTSIB). The test will then continue for 30 seconds, during which time the number of balls caught will be noted

Secondary Outcome Measures

Name	Time	Method
Hand-eye coordination assessment with alternate hand-wall toss test	Baseline and immediately after caffeine intake	Alternate hand wall toss test will be used to measure hand-eye coordination. The Alternate-Hand Wall-Toss Test is a test of hand-eye coordination, where the participant throw a ball against a wall from one hand in an underarm action, and attempt to catch it with the opposite hand. The test will then continue for 30 seconds, during which time the number of balls caught will be noted.
