Sažetak
The study presents cardiorespiratory fitness related data on two ancestrally different populations inhabiting western and eastern parts of the eastern Adriatic island of Hvar. The island is small, fairly homogeneous in its physical environmental conditions, but with clear ethnohistorical differences between west and east. Previous analyses of sociocultural and biological characteristics demonstrated that marked heterogeneity between western and eastern populations still exists. Both populations have traditionally been occupied in agriculture and fishing which entails strenuous physical labour. The sample comprises 181 males and 124 females, aged between 20 and 50 years, from 9 villages, which is 10.3% of their adult population. Cardiorespiratory fitness was represented by blood pressures (systolic and diastolic), maximal oxygen consumption (VO2max), and lung volumes (FVC and FEV1). Data were collected from health and lifestyle questionnaires, anthropometric body composition measures, submaximal bicycle heart rate tests, ventilatory tests, and other clinical measures. Anthropometric profiles of the Hvar populations indicate their satisfactory nutritional status in comparison to the U.S. normative data. There were no significant differences in lean body mass and subcutaneous body fat distribution between west and east. The western group was fatter and had more solid and stocky body build. Lung volumes of the two populations were within 87 - 108% of the CECA reference values. Both populations showed normal blood pressures and average VO2max. Differences in cardiorespiratory fitness were tested using a number of anthropometric, physiological, and behavior covariates for each cardiorespiratory trait (age, body fat and fat distribution, stature and chest dimensions, resting heart rate, blood pressure, smoking history). Significant effect of regional affiliation was found for lung volumes and VO2max in females. All adjusted values were higher in the eastern group. No significant regional differences were shown in males. The findings may reflect ancestral differences that persist today among populations living in the common biotope. Having in mind the extreme phenotypic plasticity of the studied physiological traits, there might also be important physical environment or lifestyle related characteristics not measured in this study that would explain regional and sex differences in cardiorespiratory phenotypes.
