An evolutionary perspective on human physical activity: implications for health.

摘要: At present, human genes and lives are incongruent, especially in affluent Western nations. When our current genome was originally selected, daily physical exertion obligatory; biochemistry physiology designed to function optimally such circumstances. However, today's mechanized, technologically oriented conditions allow even promote an unprecedentedly sedentary lifestyle. Many important health problems affected by this imbalance, including atherosclerosis, obesity, age-related fractures diabetes, among others. Most physicians recognize that regular exercise is a critical component of effective promotion regimens, but there substantial disagreement about details, most importantly volume: how much caloric expenditure, as activity, desirable. Because epidemiology-based recommendations vary, often confusing alienating the health-conscious public, independent estimate, arising from separate scientific discipline, desirable, at least for purposes triangulation. The retrojected level ancestral activity might meet need. best available reconstruction suggests World Health Organization's recommendation, 1.75 ( approximately 2.1 MJ (490 kcal)/d), closely approximates Paleolithic standard, which genetic makeup selected.
