This preliminary study was designed to survey general physical activity types of young Korean adults. In addition, perception of intensity for daily activities were compared to the known physical activity compendium for estimating metabolic equivalent (MET). A group of college students (44men, 25±2yrs, 175±5cm, 71±9kg, 23±3kg·m-2; 21women, 23±1yrs, 165±5cm, 51±6kg, 19±2kg·m-2) was selected and they responded to one survey and two questionnaire sessions. For the survey, they wrote down all the activities occurring at normal days. Based on the activities written, 55 activities were arbitrary selected and utilized to construct a questionnaire, which asked perceived intensity of daily activities. The intensity was scaled at 10 levels from 1; `comfortable and no physical endeavor at all` to 10; `physically challenged and exerted can`t be maintained`. The same questionnaire was administered twice with 2 days apart for the test-retest reliability. A total of 116 activities was identified, and the average number of written activities was 18.3±6.2 for men and 20.0±8.0 for women (ranged 8-35). The frequency of written activity for >41, 31-40, 21-30, 11-20, and 10> was 7, 4, 5, 18, and 82, respectively. The MET level distribution for 55 activities was 9, 21, 14, 5, and 6 for 1≥, 1.01-2, 2.01-3, 3.01-4, and >4.01 MET, respectively. The perception level for actual MET of 0.99, 1.70, 2.61, 3.66, and 6.75 was 1.75, 2.86, 3.69, 3.83, and 4.94, respectively. The regression analysis revealed the slope of preception for MET was 0.387. Based on the results, It was considered that more than 80% of daily activities was less than 3 MET intensity. Respondents overestimated activity intensities below 4 MET and underestimated above 4 MET. The slope of perception was less steeper than the actual MET.
