This study incorporated posture improvement issue into health related physical fitness, and focused on shoulder posture as the target, combining with the promotion of aspects in health related physical fitness to provide course content that improves posture through exercise. We adopted quasi-experiment design and randomly assigned two classes as the experiment group (incorporate posture improvement issue) and the control group (without incorporating posture improvement issue). The aim of this study was to compare the changes in the posture of round shoulders prior and post course between students that are with and without incorporating posture improvement issue, and investigate the correlation between the degree of round shoulder changes and the changes of indicators in physical fitness test. The result shows that the round shoulder posture of all students has improved significantly after taking the course (right and left shoulder in control group：T=6.341, p=.000, T=8.376, p=.000; right and left shoulder in experimental group：T=11.937, p=.000, T=7.549., p=.000). Comparing the two groups, it was found that the improvement of the round shoulder at the right shoulder in experimental group was significantly better than that of the control group (T=-2.121, p=.038). These findings revealed that this health related physical fitness course helps to improve poor shoulder posture, and there is an intervening effect in this course that incorporated posture improvement issue. Furthermore, according to the results of physical fitness test, there were no significant changes on the trunk forward flexion, broad jump and three minutes step test in control group. For the experimental group, in addition to the significant increase on the broad jump, there were no significant changes on the trunk forward flexion and three minutes step test, but the degree of improvement in the right round shoulder posture was not significantly related to the degree of progress on broad jump. This study demonstrated that the health related physical fitness course could effectively improve the students’ round shoulder problem through incorporating posture improvement issue, but the improvement of round shoulder posture was not related to the progress of indicators in physical fitness tests.
