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

Does a Cup of Turkish Coffee Affect Postural Control and Hand-eye Coordination in Young Adults? A Quasi-experimental Study

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.

Study Overview

• Status: Completed
• Conditions: Caffeine; Balance; Distorted; Coordination and Balance Disturbances
• Intervention / Treatment: Other: Caffeine intake

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.

Intervention / Treatment

Experimental: Study group; 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.

Other: Caffeine intake; One cup of Turkish coffee contains 60 mg/65 ml (1 Turkish coffee cup) of caffeine. Participants will be instructed to sit for 10 minutes before drinking coffee. To prepare the Turkish coffee, 5 g of ground dry coffee will be mixed in 100 mL of tap water and left to boil in a coffee machine. When the first boil starts, it will be removed from the machine and poured into the cup. Then, 65 ml of Turkish coffee will be given to the subjects to ensure oral caffeine intake.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Postural control assessment with Biodex Balance System	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	Baseline and immediately after caffeine intake

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hand-eye coordination assessment with alternate hand-wall toss test	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.	Baseline and immediately after caffeine intake
