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

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.
