INTRODUCTION:
The purpose of this study is to provide basic exercise rehabilitation data necessary for improving muscle imbalance, movement control, and shoulder stability in adult and elderly women by providing verification and evidence for the effect of selecting specific muscles according to exercise tools using Smovey and Dumbbell. The subjects of this study were those who had no shoulder or upper limb instability and musculoskeletal diseases, and who had no history of shoulder joint surgery in the last year.
METHODS:
All data were plotted by calculating the average and standard deviation between the group and the exercise on the muscle activity results of adult and elderly women using the SPSS 26.0 program, and two-way ANOVA with repeated measure was performed to verify the average difference. Paired sample t-test was conducted to find out the interaction effect between exercise, and independent t-test was conducted to find out the interaction effect between groups. In addition, one-way ANOVA was performed for each time point, and if there was a significant difference, post-verification was performed with a sketch. The significance level was set at p<.05.
RESULTS:
First, the results of this study showed a significant difference in upper limb muscle activity during flexion-extension movement of shoulder joints using Smovey and Dumbbell (p<.001). Second, there was a significant difference in upper limb muscle activity during abduction-adduction movement of shoulder joints using Smovey and Dumbbell (p<.001).
CONCLUSION:
Vibration generated by Smovey exercise affects not only the working muscles but also the cooperative muscles, strengthening the overall muscle activity of the upper extremities and the stabilizing muscles of the torso. A study comparing the muscle activity of Smovey and Dumbbell exercises helps to select the appropriate tool for the development of muscle function for each subject and provides basic exercise rehabilitation data necessary for improving muscle imbalance, movement control, and shoulder stability in adult and elderly women.
