[Measure of fitness and physical activity related to cardiovascular diseases and death].

The quality of fitness (aerobic capacity, maximal endurance performance or highly related physiological parameters) or physical activity improving fitness show a tight, reverse correlation to the all-cause and to the cardiovascular mortality within. The most fit one third of the population expect a 30-40 percent smaller chance for cardiovascular events, compared to the less fit third quarter. Low fitness (that can be changed) is just as a threatening risk factor as the traditional ones, its detection calls out for simple interventions to improve fitness: proper physical exercise.
