[6 "non-natural", yet most natural conditions necessary for health].

The medieval preventive medical scheme which persisted up to the period of Enlightenment, called the "Six Things Non-natural and Necessary", comprised six items whose influence on the health of the individual is not inborn (not determined by innateness), but no one can avoid facing them in his life (hence, they are "necessary"); however, they may be tackled in ways either promoting or impairing health (viz.: air, food, exercise, sleep, emotions, cleansing and sexuality). The taxative list of "Six Things" is normalized in book Six of Hippocratic "Epidemics"; later, the topos was furthered by Galen, John of Alexandria (and other Alexandrinian authors) and Hunain ibn Ishaq. At least nine authors in Bohemia, Moravia and Slovakia divulged the "Six Non-natural Necessary Things" from the 15th to the end of the 18th century. Due to the re-evaluation of "naturalness" on the break from Enlightenment to Romantism, the concept of "non-natural" conditions of health was abandoned; during the period of analytical medicine relevant questions were side-tracked; only the "re-synthetical" medicine (in the second half of the 20th c.) restored the original intuitive scheme of "Six Non-natural and Necessary" conditions of health in the new form of the "risk factors of health relevant behaviour".

[Comparison of the physical fitness of the young population of Czechoslovakia with similar data from other European countries].

In order to analyze the relationship between VO2 max and height, body mass and lean body mass a multi-longitudinal survey was conducted on three different age groups of randomly selected children from a small Czech community. Beginning at the initial ages of 8, 12 and 16 years subjects were subsequently retested three times at two year intervals. At overlapping ages there were no differences in the various age groups between height and VO2 max. By utilizing mean values for the various parameters at specific calendar ages a growth curve was constructed for each sex for the age range 8 to 20 years. The values were compared with longitudinal studies of various countries and no substantial differences were found. When VO2 max was then compared to height, body mass and lean body mass it was apparent that the almost linear relationship with height was the most precise. In addition the children remained, generally speaking, in their same rank order for VO2 max for the three different age groupings.

[Homesick in Capricorn's Woods. Remarks on the 300th anniversary of the dissertation on nostalgia and the 700th anniversary of "dolor de dampno"].

Nostalgia (homesickness) was introduced to the domain of medicine only in 1688, but mental suffering corresponding to it was described already in ancient poetry; in Central Europe, it appeared for the first time 700 years ago in the Chronicle of the Zdár monastery, written by Henry the Woodsculptor (= von Heimburg?). In the woodlands between Moravia, Lower Austria and Bohemia, mentioned by Ptolemaios under the Celtic name "Gabreta" (wild goats' wood, cf. Irish "gabrach"), also other behaviour patterns reflecting unusual mental anchorage patterns of the inhabitants appeared between the 13th and 17th centuries. Even if the content of the term "nostalgia" nowadays dissipated to vague "spleen" feelings, its descendant concepts flourish in modern philosophical ("thrownness", "alienation"), psychoanalytical ("existential frustration", "birth trauma," "object loss"), psychiatrical ("agoraphobia", "deprivation", "anaclitic depression") and social psychological ("cataclysmatic fears and anxieties") thought.

Favourable levels of cardio-vascular health and risk indicators during childhood and adolescence.

This paper is concerned with favourable levels of constitutional cardio-vascular health indicators during childhood and adolescence. A cross-sectional randomised sample of healthy Czechoslovakian children was investigated, because this population is habituated to a favourable life style. Twenty girls and 20 boys at ages 8, 12 and 16 years were recruited to the study. Statistical data for means and standard deviations are presented with regard to maximal aerobic power, haemodynamic variables such as arterial blood pressure, heart rate at submaximal and maximal muscular exercise, body fat content, blood lipids including total cholesterol and its fractions, high- and low-density lipo-proteins, fasting triglycerides and the apo-lipo-protein profile. The maximal oxygen uptake in absolute values increased with age in both sexes and the boys appeared to average higher than the girls at each age. When maximal aerobic power was expressed on a total body weight basis, boys appeared to average higher at age 16 years (56 ml X min-1 X kg-1) than girls (45.8 ml X min-1 X kg-1). The highest recorded heart rate for ergometric work averaged close to 200 min-1 in both sexes with no significant age differences. The diastolic blood pressure at rest did not change significantly with age or sex. Serum cholesterol levels were found to decrease significantly after puberty in boys (post-pubertal dip), but in the girls there was found no systematic change in mean values with age. When HDL was expressed as a percentage of total cholesterol there appeared to be no differences related to age and sex.(ABSTRACT TRUNCATED AT 250 WORDS)

Circulatory and respiratory responses to muscular exercise in Czech and Norwegian children.

This paper presents a comparison between Czech and Norwegian rural healthy children with regard to the functional characteristics of the circulatory and respiratory system based upon work physiological variables and measurements of some pulmonary volumes. The study included randomised samples of boys and girls at the age of 8, 12 and 16 years, 66 Czech boys and 63 girls, 54 Norwegian boys and 57 girls. At the age of 8 years the maximal aerobic power was closely similar in both countries, but in the older age groups the Norwegian children exhibited lower physical fitness. The maximal heart rate was close to 200 min-1 on the average without any sex, age or ethnic differences. In agreement with the higher maximal aerobic power the 12 and 16 year old Czech children had lower submaximal heart rates for the same oxygen uptake than the Norwegian children. The forced vital capacity and forced expiratory volume in one second was significantly higher on the average in Czech than in Norwegian children but the latter, expressed in percent age of the former, averaged 87 to 91% without any sex, age or ethnic differences. The maximal ventilation volumes during muscular exercise reached higher values in Czech than in Norwegian children of the same age, but the mean maximal respiratory rate was close to 60 min-1, being independent of age, sex and cultural differences. During heavy exercise only 40 to 50% of the vital capacity and 45 to 55% of the forced expiratory volume were taken into account and this index of pulmonary function did not differ with sex, age or ethnic differences.
