Waterpolo is a sport which
characteristic is high aerobic endurance. Children are enrolled in the
process of training already at the age of 10 and 11.
Studies
of some authors show that there are differencies in some of the
cardiorespiratory parameters between young athletes enrolled in the
process of waterpolo training and those who do not practice sport
actively.
The aim of our study was to spot the difference in
some of the parameters (absolute oxygen consumption VO2 (ml/min),
relative oxygen consumption VO2/kg (ml/min/kg), bodymass index (BMI),
percentage of muscles and oxygen consumption per kilogramme of muscle
tissue, between two groups of young representative waterpolo selections
aged 1988 to 1990 and 1991 do 1993).
By applying the T-test to
small indipendent samples on the level of statistic significance
α=0.05, we spotted a difference in BMI, while regarding all
the other parameters, we didn't notice any significant difference. This
shows that the training stimulus leads to identical adaptive changes in
cardiorespiratory system and that the spotted difference probably
arises from a different degree of biological development.
Key
words:
waterpolo, oxygen consumption, BMI, young athletes.
