Exercise does not increase contrast sensitivity

Woods, Russell L. , Wood, Joanne M., & Jack, Michelle P. (1997) Exercise does not increase contrast sensitivity. Clinical and Experimental Optometry, 80(5), pp. 173-177.

Abstract

The contrast sensitivity of 19 healthy normal subjects was measured before and immediately after 10 minutes of controlled exercise on an exercise bicycle. Contrast sensitivity was measured with an adaptive procedure, which is relatively free of decision criteria effects and the rate of false positive responses was recorded. Ten of these 19 subjects then formed a control group, where contrast sensitivity was measured before and after a 10-minute period of rest.

We found no change in either contrast sensitivity or the false positive response rate after exercise. Similarly, there were no changes after the period of rest in the control group. Hence, previous reports of improved contrast sensitivity resulting from exercise, which have used a less robust psychometric method to measure contrast sensitivity, may have measured a change in the subject’s decision criteria rather than a change in contrast sensitivity.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
