In order to maintain the highest level of scientific validity, participants are placed in a study group through random assignment rather than by request. This is done by an automated system through which the outcome has no outside influence. Every participant (including those originally placed in the wait list group) will have the chance to participate in either the Tai Chi or cycling exercise program.
