Sažetak
The aim of this research was to establish ventilatory lung function in four age different young water polo players groups and check the differences in lung capacities and volumes between the groups. The assumption is that the young water polo players and control group of non players will present differences in parameters of lung capacities and volumes.
Methods: The sample consists of 120 participants examined, divided in four age groups. Experimental group consists of 60 water polo playesr aged from 10 to 17. Control group consists of 60 non sportsmen of equal ages. Experimental group was formed from players from water polo school, young cadets, cadets and young juniors, 15 members in each group. The control group was chosen at random access method. All examiners were clinically healthy without morphological, motorical and psychical aberations.The sample of variables consisted of six variables of ventilatory lungs: inspiratory vital capacity, forced vital capacity, forced expiratory volume in one second, forced flow rates at 50% FVK, forced flow rates at 25% FVK, peak flow, two anthropomorphic measures (height and weight of the body) and examinee age. We performed one way analysis of variance and discriminating canonical analysis to establish the differences between the groups.
Results: There were no changes in relative ventilatory lung function after one year of training. Three years of organised training brings significant changes in relative ventilatory lung functions (dominantly in static lung ventilatory VKIN ref.; FVK ref.) and little bit less, but significant positive changes in dynamic lung ventilation (FEV 1% ref. , and MEF 25% ref.). Five years training contribute changes in dynamic lung ventilation ( FEV 1% ref., MEF 50% ref. and MEF 25% ref.). The efects of 7-years organised training bring significant changes in dynamic lung ventilation variables (FEV 1% ref., MEF 50% ref.).
Conclusion: Water polo training duration of 3, 5 and 7 years generate growth of ventilatory lung function. Young water polo players who take up multiannual training have increased values of variables that measure ventilatory lung functions. Water polo training of 3 years, statistically significant increased statical and dynamical ventilatory lung functions. Water polo training of 5 and 7 years dominantly elevates dynamical ventilatory lung function values. Analysis shows that constant long term water polo training in the context of young players trainings quantity and duration leads easily to measurable improvements in ventilatory lung function, compared to general population.
