Fitness in general includes both aerobic and anaerobic aspects. According to the priorities of the sportsman, one or the other of the two aspects will be emphasized, but the second one will not be neglected. The purpose of doing fitness exercises is, ideally, to create a complete athlete, able to face various physical and psychological demands.
The object of aerobic fitness is the so-called cardio training, a term which refers to the cardio-vascular system and the heart muscle (myocardium). We’ll talk about trainings which do not make oxygen duty and which are generally called ‘trainings of aerobic effort’. More exactly, they refer to efforts which take a long time (more than 12 minutes) – usually they take between 20 and 60 minutes and they determine acceleration of cardiac frequency and lung ventilation. Efficiency in training requires a frequency between 60-80% of the maximum cardiac frequency (calculated according to the formula 720-age – in years).
