[Purpose] This study aimed to examine the effects of physical activity on forward head and rounded shoulder postures in healthy young adults. [Participants and Methods] We recruited 20 healthy young adults engaged in high levels of physical activity and 20 healthy young adults engaged in low levels of physical activity. Both groups completed the International Physical Activity Questionnaire (IPAQ) to assess their physical activity levels. The scapular index (SI) was calculated to assess rounded shoulder posture, whereas the craniovertebral angle (CVA) was calculated to assess forward head posture. Differences in SI and CVA between the two groups were examined. [Results] There was a significant difference in the SI between the two groups, with the low physical activity group exhibiting a lower SI than the high physical activity group. However, there was no significant difference in the CVA between the two groups. [Conclusion] Our study showed that low physical activity levels in healthy young adults could negatively affect shoulder posture but not head posture. Therefore, regularly monitoring rounded shoulder posture in individuals with low physical activity levels is recommended for health considerations.
