Abstract：Physical inactivity is one of 4 major risk factors of non-communicable diseases (NCD). Regular exercises decrease risks in morbidity and mortality of NCDs. The purpose of this paper is to discuss the health effects of different types and amounts of daily physical activity. Utilizing keywords such as daily physical activity and mortality, study reports in the epidemiology, disease morbidity and mortality effects of various activity types (sitting, standing, stair climbing, domestic/household physical activity, and occupational physical activity) were identified and explored. The results indicate that reduced sitting time and increased standing time, walking, stair climbing, and domestic/household physical activity would benefit health. The optimal physical activity amount for health should be 5 times the minimal physical activity recommended by the World Health Organization, which is 750 minutes 4 MET (metabolic equivalent of task) (moderate) a week, or 375 minutes 8 MET (vigorous) a week. We conclude that these findings should be adopted in official health recommendations. (Full text)
