Abstract
The purpose of the present study was to determine the target heart rate during physical exercise adjusted to habitual physical activity in order to aid inactive aged persons.
Heart rate (HR) were recorded continuously for 24 hrs from 16:00 with portable HR memory to see the level of physical activities in 10 men (aged 68-85yrs) and 10 women (aged 63-74yrs). They were members of a sport class for the aged. Anamnesis and informations abous hours spent for sport, walking, cycling, and sleep were taken from the subjects. HR and blood pressure at rest and body weight were measured every week before exercise.
Pattern of habitual physical activity of individual case is (1) inactive, or (2) active but slow-moving; play gate-ball, over 3 days/week, or (3) active and quick-moving; play trim gymnastics, folk dance, or table tennice, 1-3 days/week. The majority of active but slow-moving ones are border hypertensive or hypertensive. On the basis of peak HR during 24hrs, HR 90s beat/min is considered to be optimal as the initial target HR for inactive or active but slow-moving ones, and HR 100-120 beat/min is optimal for active and quick-moving ones.
