Abstract

The purposes of the study are to make clear the present situation of snow removal maneuver performed by older adults in snowy regions and to elucidate the interrelationship among physical fitness, activities of daily living and capability of snow removal.<BR>Questionnaires on lifestyle and physical activities were distributed to 334 elderly males and 397 elderly females who are living independently in Hokkaido. Among these respondents, physical fitness test developed by Japanese Ministry of Education, Science and Culture and questionnaires on Activities of Daily Living were performed on 102 elderly male subjects and 196 female subjects to extract the physical fitness factors for snow shoveling.<BR>Higher percentages of the respondents answered to be engaging snow removal every snowfall, that is to say, 80%, 88% and 73% at age ranges of 65-69, 70-79 and 80-89 years in males, and 46%, 47% and 27% at age ranges of 65-69, 70-79 and 80-89 years in females, respectively. Since no difference was seen in the percentages of the subjects who are engaging snow removal every snowfall between the groups either outpatients group and non-outpatient group, or high blood pressure group and normotensive group in males, a large part of older adults males strain themselves demanding work. Significant differences were observed in mean values in age, physical fitness between the two female groups who are engaging snow removal every snowfall and the female group who are impossible to snow removal because of lower fitness, that is to say, 72.8±6.1 vs 78.6±7.3years in age, 148.2±5.4 vs 145.3±7.0cm in height, 22.7±5.0 vs 19.1±5.3kg in grip strength, 10.1±3.9 vs 13.2±5.3 sec in 10m hurdle walk time, 494±77 vs 426±88 m in 6-minutes walk distance, and 2'7.1±4.5 vs 22.0±4.7 point in activities of daily living score, respectively.<BR>Therefore, it was concluded that physical fitness factors such as strength, leg power, endurance are an important determinants of the snow removal for older adults in snowy regions.
