Summary In a Czechoslovakian population ranging in age from 12–55 years, physical fitness was examined. Heart rate increased linearly with power output, but the slope decreased with age up to 18 years in men and 15 years in women. Maximum heart rate decreased linearly with age in both sexes: from 193 beats/min at 12 years to 169 beats/min at 55 years in males, and from 198–174 beats/min in females at corresponding ages. The value of W 170/kg varied between 2.4 and 2.8 W in men, and 1.7–1.9 W in women; it decreased slightly with age in men, but remained steady in women. Systolic blood pressure at maximal work load rose with age. The incline is steeper in men: from 138/56 torr at the age of 12 years to 190/84 torr at 55 years, compared with 139/57 torr and 182/84 torr in women of similar ages. Pulmonary ventilation at submaximal work load depends linearly on load level, but hyperventilation occurs as the degree of load increases. In older subjects (over 40 years of age) hyperventilation is more profound. The peak values (112 l/min for men and 83 l/min for women) are attained equally in the 18th year of age; a mild decline then follows. Data on oxygen uptake expressed in absolute units ron in parallel, the maximum of 3.28 and 2.17 l/min for men and women, respectively, being reached at the age of 18. When related to body weight, oxygen uptake linearly decreased, within the age range followed, from 48.5 to 32.9 ml/min·kg in men, and from 40.3 to 26.5 ml/min·kg in women. We can thus conclude that the physical fitness of the Czechoslovakian population, as indicated by different functional variables, is similar to that reported for other populations with comparable living conditions.
