The following are abstracts of poster presentations accepted for the StairMaster Conference on Aging and Physical Activity, October 21–23, 1993, in Virginia Beach, Virginia. In planning the conference, the goal for both the invited presentations and poster sessions was to include a balance of scientific research, professional application, and program development information. The abstracts are organized alphabetically according to the last name of the first author. A special thank you goes to the Journal of Aging and Physical Activity reviewers who participated in the review process. Articles based on the invited conference presentations will appear in future issues of the Journal.
