健身運動「每日一萬步」之探討
摘要
In the views of public health and exercise, accurate exercise prescription can encourage people to exercise. For example, the US Centers for Disease Control and Prevention (CDC) and The American College of Sports Medicine (ACSM) recommend that ”at least 30 minutes moderate intensity daily physical activity, such as brisk walking”. The activity, walking, is the basic and simple exercise, and is the less limited exercise by environment factors in daily physical activity. Pedometer is one kind of convenient and inexpensive motion sensors of tracking daily physical activity (especially walking) that expresses as a summary output of steps/day. Many researchers and participants used pedometers to record steps/day, and hoped that, by the reason, it could increase daily physical activity. In 2002, Bureau of Health Promotion, Department of Health, R.O.C. (Taiwan) proposed the ideal ”10,000 steps/day can promote health”. A value of 10,000 steps/day is in fair agreement with health adult physical activity level (about 9,000~11,000 steps/day) and the concept is gaining popularity of the world. Considerations to the difference between different groups, preliminary evidence suggests that a goal of 10,000 steps/day is probably too low for children (girls about 11,000 steps/day, boys about 13,000 steps/day), and it may not be sustainable for some groups, including older adults and those living with chronic diseases. The value of 10,000 steps/day is somewhat a hard goal for some populations, such as manufacturing workers. However, compared with 30 minutes moderate intensity daily physical activity, 10,000 steps/day has efficacious effect and it also has the advantage of sustainable effect.
