Abstract

Background: The aim of the present study was to assess physiological-biochemical reactions to incremental exercise loads and the levels and development of endurance skills in young male and female team game players. Material/Methods: The study sample comprised 370 soccer, handball, basketball and volleyball players (186 girls and 184 boys) from the Lower Silesian Regional Teams in Poland, aged 14.20 ±1.37 years (boys) and 13.90 ±1.15 years (girls). The exercise test consisted of the shuttle run Beep Test for estimation of aerobic fitness. The assessment of endurance skills was based on the length of the covered distance in the Beep Test as well as on measurements of the heart rate (physiological) and blood lactate concentration (metabolic). Results: Among the four studied groups of players a statistically significant improvement in endurance skills was noted in male volleyball players (p ≤ 0.05). Conclusions: Significantly higher levels of endurance skills in young male handball, basketball and volleyball players and in female volleyball players who remained on the regional teams for two consecutive years may be an indication of the players’ proper selection and training. Significant changes in blood lactate concentration in young players, revealed in both cross-sectional and continuous studies, were only noted in male volleyball players. Significant decreases in the heart rate in the cross-sectional study was found only in male handball and basketball players and in female basketball players, whereas in the continuous study only in male handball players. An assessment of young players’ physiological-biochemical reactions on the basis of exercise test results can effectively enhance the optimization of training loads.
