Abstract des Autors

The purpose of this study was to examine the effects of three cognitive strategies - imagery, preparatory arousal and counting backwards - on the hand grip strength of college age and older subjects. Additionally, this study analyzed the relationship of age differences on perceived exertion and state anxiety to grip strength. An analysis of the results revealed that imagery significantly enhanced strength as compared to the counting backwards strategy across all groups. However, imagery was no more effective in enhancing grip strength among the older subjects as compared to the young subjects. Analyses of perceived exertion and anxiety revealed little relationship to subjects' grip strength scores across sex and age. The results are dicussed in terms of the values of using mental I preparation among older adults. Verf.-Referat
