Purpose: Many studies emphasize that smoking has negative effects on cognitive function and muscle strength. Therefore, the study aimed to compare cognitive function, motor performance, and dual-task of sedentary healthy young individuals according to smoking status.
Methods: In the descriptive study, young adults between the ages of 18 - 25 were included. Participants were divided into two groups; smokers and non-smokers. General cognitive status was evaluated with the Standardized Mini Mental Test (SMMT) and executive function with the Stroop test. For motor performance, quadriceps femoris muscle and grip strength assessed and Extended Timed Up and Go (ETUG) test were used. Participants’ dual-task gait performance was assessed with an auditory task concurrent with the ETUG. Shapiro-Wilk test was used for data normality. Due to the variables were not normally distributed, intergroup comparisons were evaluated with Mann Whitney U test.
Results: 62 participants with a mean age of 21.08 ± 1.08 and a body mass index of 21.73 ± 2.76 were included. In intergroup comparisons, there was no difference between two groups in cognitive function, quadriceps muscle strength and grip strength (p>0.05). There was a difference in favour of non-smokers between two groups in ETUG and cognitive ETUG (p<0.05).
Conclusion: In conclusion, smoking causes performance loss in both dynamic functional activities and dual-task in young adults.

Amaç: Birçok çalışma sigaranın bilişsel fonksiyon ve kas kuvveti üzerinde olumsuz etkileri olduğunu vurgulamaktadır. Bu nedenle çalışma, sigara içme durumuna göre sedanter sağlıklı genç bireylerin bilişsel fonksiyonlarını, motor performanslarını ve çift görevlerini karşılaştırmayı amaçladı.
Yöntem: Tanımlayıcı tipteki çalışmaya 18 - 25 yaş arası genç yetişkinler dahil edildi. Katılımcılar iki gruba ayrıldı; sigara içenler ve içmeyenler. Genel bilişsel durum Standardize Mini Mental Test (SMMT) ile ve yürütücü işlev Stroop testi ile değerlendirildi. Motor performans için kuadriseps femoris kası kuvveti ve kavrama kuvveti değerlendirildi ve Genişletilmiş Zamanlı Kalk ve Yürü testi (GTUG) kullanıldı. Katılımcıların çift görev yürüyüş performansı, GTUG ile eş zamanlı bir işitsel görev ile değerlendirildi. Veri normalliği için Shapiro-Wilk testi kullanıldı. Değişkenler normal dağılmadığı için gruplar arası karşılaştırmalar Mann Whitney U testi ile değerlendirildi.
Bulgular: Yaş ortalaması 21,08 ± 1,08 ve vücut kitle indeksi 21,73 ± 2,76 olan 62 katılımcı dahil edildi. Gruplar arası karşılaştırmalarda iki grup arasında bilişsel fonksiyon, kuadriseps kas kuvveti ve kavrama kuvveti açısından fark yoktu (p>0,05). GTUG ve bilişsel GTUG'da iki grup arasında sigara içmeyenlerin lehine fark vardı (p<0,05).
Sonuç: Sonuç olarak, sigara genç yetişkinlerde hem dinamik fonksiyonel aktivitelerde hem de çift görevde performans kaybına neden olmaktadır.
