The development and results of a technique to determine the behavioral effects of exercise induced arousal on the performance of mental tasks were described. A total of 11, healthy, nonsmoking male subjects between 20 and 30 years of age performed a variety of mental tasks including serial visual four choice reaction time (SCRT), discrete visual four choice reaction time (CRT), unexpected auditory response time (URT), and index finger tapping tasks over a period of 2 days while exercising on a paramagnetic cycle ergometer. Four work levels (rest, 30 percent VO2max, 60 percent VO2max, and recovery) and three movement conditions (nonmovement, continuous pedaling, and interrupted pedaling) were monitored. The independent variables were practice between the 2 days, physical work, and movement. Significant correlations were established between tapping speed and movement condition, CRT reaction time and work level, SCRT reaction time and movement condition, and SCRT reaction time and practice. The author concludes that the method can be used to determine specific types of work tasks that will be disrupted by exercise induced arousal.
