Examination about amount of activities and intensity in sports cardiac rehabilitation

Abstract

The quantity and level of daily activities of patients regularly participating in cardiac rehabilitation were evaluated. The subjects were 17 patients with ischemic heart disease (10 males aged 71.9±6.0 years,7 females aged 68.7±3.4 years). The mean duration of rehabilitation was 7.6±4.5 years (0.5±14.7 years). The activities of the subjects were recorded for 1 week using activity recording sheets and an activity recording apparatus (Lifecorder, Suzuken). The mean daily number of walking steps was 9,207 in the males and 6,264 in the females. Concerning daily activity times, the females spent about 80% of the day at home, and they spent a mean of 11.1 hours (46.4%) on "other activities", probably affecting the time spent on hobbies (0.7 hours, 3%) and sports (1.0 hours, 4%). The level of activity was zero for 94.5% of the day in the males and 95.8% of the day in the females, and moderate for 1.4% of the day (about 20 minutes) in the males and 0.8% of the day (about 13 minutes) in the females. The patients participated in rehabilitation and regularly performed sports, but their weekly activities were insufficient in both the quantity and level. Particularly, the lack of activities of moderate levels was notable in the females.
