Objective: The aim of this study was an analysis for accuracy of subjective ratings for target force levels (%MVC Levels) when there is no feedback of exertions for participants in this analysis. Background: Many studies of perceived force exertion about the static contractions have been conducted with using the Borg CR-10 scale for various levels of target force exertions (i.e., %MVCs). However, there was only few studies for how people correctly estimate their subjective ratings of the grip strength associated with target force levels under no feedback. Method: A total of 10 healthy males were asked to perform their maximum grip strength, and then each participant was also asked to evaluate the subjective rating with the random target force levels (10 ~ 90% MVCs). Results: As the target force level was increased, subjective rating was also increased. In accuracy of subjective ratings for target force levels, 30, 40, 50, and 90% force levels were accurately estimated by the subjective rating of grip strength. However, participants under-estimated for the 10% and 20%MVC, whereas over-estimated for the 60~80% MVCs, respectively. Conclusion: Based on the study of accuracy of subjective perceive ratings for target force levels, people showed under-estimation for the relatively lower levels of target force levels and over-estimation for the higher levels of target force level (90% MVC). Most participants estimated fairly accurate subjective ratings for the target force levels of 40~50% MVCs. Application: The results of this study may applied as for understanding of the subjective rating of grip strength pattern based on the various voluntary grip force levels.
