Physical aktivity and human evolution

Six million years ago the story of human evolution began. About 40,000 years ago anatomically modern humans, Homo sapiens sapiens, emerged. To survive in a harsh environment full of natural and human obstacles and enemies, early man had to know how to keep fit to survive. From a genetic standpoint, humans living today are Stone Age hunter-gatherers displaced through time to a world that differs from that for which our genetic constitution was selected. Unfortunately, physical inactivity dominates most developed nations around the world, and is among the leading causes of disease burden and death worldwide. It was suggested that besides environmental factors also genetic/ biological factors influence voluntary physical activity. It is recommendable to seek the ways how to achieve improvement of recently prevailing sedentary life-style, otherewise rising prevalence of sedentary death syndrome could be expected.
