Sažetak
PURPOSE: The principal aim of this investigation was to assess tracking of cardiorespiratory fitness and fatness from adolescence to adulthood. METHODS: The sample consisted of 62 participants (36 male ; 26 female), median age: 43 (range: 36-43). During adolescence measurements were taken at the age of 15. The same procedures were repeated 18 or 25 years later when the participants were around 36 or 43 years old. Fatness was evaluated through body mass index (BMI) and the sum of triceps, calf, suprailiac and subscapular skinfolds while fat distribution was assessed through the ratio of central skinfolds and the sum of skinfolds. Peak oxygen uptake was measured by a portable breath-by-breath metabolic system during a maximal treadmill exercise test. In addition, ventilatory aerobic and anaerobic thresholds were determined. RESULTS: BMI and subcutaneous fat showed very moderate to good tracking from adolescence to middle adulthood in both gender, while for body fat distribution this was true only in men but not women. Interage correlations from adolescence to middle adulthood reached 0.61 (p<0.001), 0.54 (p<0.001) and 0.51 (p=0.003) in males and 0.17 (p=0.47) in females for BMI, sum of skinfolds and skinfold ratio, respectively. The observed tracking of cardiorespiratory fitness was less good. Peak oxygen uptake tracked moderately (partial r=0.50, p<0.001 for absolute VO2peak and partial r=0.30, p=0.03 for relative VO2peak), whereas no tracking of aerobic (partial r=0.07, p=0.62) or anaerobic threshold (partial r=0.16, p=0.31) was noted for the same age interval. CONCLUSIONS: Fatness tracked reasonably well from adolescence to middle adulthood, whilst tracking of cardiorespiratory fitness for the same age interval was poor to moderate for some indicators of fitness or not significant for the others. Therefore, preventive strategies regarding fatness should focus on high-risk groups of adolescents. Conversely, strategies to increase cardiorespiratory fitness should not be focused on adolescents with low fitness, but include all adolescents irrespective of their cardiorespiratory fitness status.
