Lower extremity strength as a function of exposure to pictorial stimuli of the same hue

20 May 1990


The theoretical base of this research study was to examine how an image would affect strength output. The experiment included two types of images. One of the images represented strength, power, and endurance. The other image represented silence, relaxation, and tranquility. I hypothesized the image focusing on strength would motivate subjects and increase strength output.

Fifty university students were randomly selected into two groups. Group one viewed a non-motivational image. Group two viewed a motivational image. A Cybex isokinetic dynamometer was used to assess quadriceps strength as the subject focused on the specific image.

An independent t-test was used to interpret the data. Results indicated that group two (shown the motivational image) had a higher quadriceps strength output than group one (shown the non-motivational image). These results supported the original hypothesis: subjects focused on a motivational image produce a higher strength output.
