Maximal aerobic ( {Mathematical expression}) and anaerobic power ( {Mathematical expression}), fat free body weight, maximal cardiac output ( {Mathematical expression}) stroke volume (qmax) of the heart and the O2 capacity of the blood (Hb) were measured on 145 subjects in the age range 9-64 selected at random on a population of a subalpine area of Northern Italy. At the age of 17-25 years ( {Mathematical expression}) has been found to be on the average 41.5 ml/kg · min in the males and 33.9 ml/kg · min in the females: when referred to 1 kg of lean body weight ( {Mathematical expression}), it amounts to 48 and 46 ml O2/kg · min respectively. ( {Mathematical expression}) expressed as ml O2/kg · min in the same group of individuals is 173 for males and 146 for females. When referred to 1 kg of lean body weight the maximal anaerobic power is respectively 201 and 199 ml O2/kg · min. Both ( {Mathematical expression}) and ( {Mathematical expression}) decrease with increasing age. ( {Mathematical expression}) appears to be a linear function of {Mathematical expression} ·q is on the average 1.6 ml per kilogram of body weight for males with a high individual variability (σ = 15%) and 1.4 for females: it appears to be independent of age.
