Purpose:The most important airway protection mechanism during swallowing is adequate laryngeal elevation. Suprahyoid muscles are responsible for laryngeal elevation. The aim of our study was to compare the effects of  three different exercises including Shaker,  CTAR  and a new method Chin Tuck with TheraBand Exercises on suprahyoid muscles activity. Methods:Forty-two healthy subjects with a mean age of  27.92±5.02 years (min=18, max=40), of which 50% were male were included. All  individuals  were divided into three groups; Chin Tuck Against Resistance (CTAR); Group 1, Shaker exercise; Group 2, Chin Tuck Exercise with Theraband (Theraband); Group 3, with computerized randomization. Surface EMG evaluation was performed to determine  electrical activity  of the suprahyoid muscles during maximal voluntary isometric contraction and during performing CTAR, Shaker exercise and Chin Tuck with Theraband. Normalized suprahyoid muscle activations were calculated  as: Recorded Maximum Electrical Activity During Exercise  (mV) / Recorded Maximum Electrical  Activity During Maximum İsometric Contraction (mV). Results:A statistically significant difference was found between three groups in terms of normalized suprahyoid muscle activiteit (p<0.001). The difference between three groups was caused by the difference between Group 1 and Group 2 (p<0.001) and between Group1 and Group 3 (p=0.040) in favor of Group 1.  No difference was found between Group 2 and Group3 (p=0.104). Conclusion:In conclusion, primarily CTAR exercise should be included in rehabilitation to increase the suprahyoid muscle activation. In addition, chin tuck exercise with Therband can also be considered as an alternative to CTAR.
