Abstract
This study aimed to clarify changes in physical function over a one-year period, as well as sex differences in elderly persons with cardiac disease during the maintenance period. A total of 29 elderly over the age of 65 （14 males： 74.1±6.0 years, 15 females： 74.0±4.1 years） with cardiac disease took yearly physical function tests over a two-year period. The 3 physical characteristics measurement, 6 Japan physical fitness tests developed by the Ministry of Education, Culture, Sports Science, and Technology of Japan, the stepping test by sitting position, and the timed up & go test were used. A questionnaire consisting of 12 items concerning daily living activities was administered to the participants. The mean differences were examined using two-way analysis of variance with one-factor repeated measurements. Muscular strength decreased in a one-year period in only one male and was superior in males in both years. Flexibility was superior in females, with any decrease over a one-year period being unnoticeable. The ability to walk decreased during a one-year period, but functional mobility improved. Decreases in equilibrium, muscular endurance, cardiorespiratory endurance, and agility were not found during the one-year period, and no sex difference was found. In conclusion, appropriate training and guidance for improving physical function relative to maintenance of muscular strength as well as an increase in the ability to walk may be required for elderly people with cardiac disease during the maintenance period.
