A variety of health-related benefits can be obtained by participating in moderate-intensity physical activity most days of the week. However, many Americans continue to remain inactive. When examining the complex behavior of inactivity one cannot avoid wondering what impact the environment has on activity patterns. A criticism of many theories of behavior change has been the emphasis on individual behavior modification, rather than on sociocultural and physical environmental influences. To learn more about factors relating to physical activity, researchers may want to approach the problem from an ecological perspective. Proximity to exercise facilities has been identified as a possible determinant of physical activity and is an environmental element possibly affecting decisions to exercise. The purpose of this study was to examine relationships between frequency, intensity, and duration of physical activity and proximity of exercise facilities and quantity and satisfaction of home exercise equipment. The subjects were (n=411) male and female undergraduate students. Stratified sampling procedures were utilized. Significant relationships between intensity and duration of physical activity and the proximity of exercise facilities were found. Intensity and duration of physical activity were found significantly correlated (r=.208, r=.204, p < .05) with proximity of exercise facilities for freshmen. Intensity and duration of physical activity were significantly related (p<.05) to proximity of exercise facilities for females. Frequency was found significantly correlated (r=-.195, p < .05) with the proximity of exercise facilities for males. All of the independent variables significantly correlated (p<.05) with quantity of home exercise equipment, but were not significantly (p>.05) related to the satisfaction of home exercise equipment. When female students were examined, the relationships between the independent variables and quantity of home exercise equipment (p<.05) were significant. However, no significant relationships were found (p>.05) for males. Freshmen and juniors had the majority of independent variables significantly related (p<.05) to the quantity of home exercise equipment. Differences in the proximity of exercise facilities were found for year in school and gender (p<.05). Freshmen, sophomores, juniors and seniors initiated activity 1,668 (.3 of a mile), 3,669 (.7 of a mile), 4,921 (.93 of a mile), and 4,607 (.87 of a mile) feet respectively from their residences. Females and males initiated physical activity approximately 3,290 feet (.64 of a mile) and 4,189 (.80 of a mile) feet, respectively from their residences. Differences were found in quantity of home exercise equipment for year in school (p<.05).
