Purpose: This study aims to analyze the role and activation of the sternocleidomastoid (SCM) muscle during normal inhalation and maximal inspiratory pressure (MIP) among healthy adults. Methods: This study included 20 healthy adults. Surface electromyography was conducted to measure SCM muscle activation during normal inhalation and MIP evaluations. The MIP was assessed with a respiratory muscle strength device, and SCM activation was normalized to the percentage of maximum voluntary isometric contraction (%MVIC). Results: The study revealed no significant differences in SCM activation between the left and right sides during normal inhalation and MIP. However, SCM activation significantly increased during MIP compared to normal inhalation. Additionally, MIP results and SCM %MVIC during normal inhalation exhibited no correlation, but MIP results and SCM %MVIC during MIP demonstrated a significant positive correlation, indicating that higher MIP values are related to increased SCM activation during this phase. Conclusion: The results indicate that the SCM plays a crucial role in assisting inspiration during increased respiratory demands. This study provides valuable information for developing respiratory muscle training programs and rehabilitation plans for patients with respiratory or neuromuscular disorders.
