Longitudinal studies have shown that VO2max increases the most as the outcome of training in the age between 15-25 (Rusko, 2003). Meanwhile, it is not clear how much this increase is connected to training or other development values. The aim
of the present study was to analyze maximal oxygen uptake longitudinally among 15-19 year old cross-country skiers and its relations with training characteristics. Methods: determination of anthropometrical data (height, weight, BMI) and aerobic capacity (VO2max) in the age period from 15 to 19 years during 5 years in 58 skiers (41 males and 17 females). Results: The dynamics of relative VO2peak (ml/kg/min) were not
signifi cant in comparison across all age groups in young male skiers. A signifi cant positive trend of VO2peak (l/min; ml/kg/min) was found in young female skiers in the 17-year-old age group compared with the previous age group. Signifi cant relationship was detected between change of training volume and change of VO2peak/kg (difference between the age of 15 and 19 years among male young skiers) (r=0.475, p=0.002). In conclusion, our study showed a moderate increase in VO2peak during the age period of 15 to 19 years, whereas the increase was more pronounced in male than female skiers. VO2peak of young cross-country skiers was associated with the age as well as with the training hours per week. |
