title: [A PARADIGM SHIFT IN THE PERCEPTION OF HEALTH MAINTENANCE FROM INCREASING PHYSICAL ACTIVITY TO DECREASING PHYSICAL INACTIVITY].
abstract: Modern man spends most of his waking hours (50-70%) in one form or another of sedentary behavior, defined as activity conducted in a sitting or reclining position involving low energy expenditure. The remaining waking hours are spent performing low intensity physical activity (25-45%) and medium-high intensity physical activity (less than 5%): Despite this distribution, medical research has focused on the impact of increasing medium-high intensity physical activity and many health organizations' recommendations are in accordance. In recent years, research conducted has begun to examine the effect inactivity has on health and has shown that excess sedentary behaviour is an independent risk factor for a wide range of medical problems such as obesity, metabolic syndrome, poor cardiovascular health profile, diabetes mellitus, and possibly cancer. Although the higher risk brought on by sedentary behaviour is partially reduced by increasing medium-high intensity physical activity, it is not completely neutralized. One way to diminish the harm caused by long hours of sitting is to take short breaks during periods of prolonged sitting in order to walk. According to these findings, it is worthwhile to recommend reducing the hours spent in sedentary behaviour, or at least to take frequent short breaks ("activity snacks") during periods of prolonged sitting to get up and walk around.
